1 00:00:00,040 --> 00:00:03,160 When you're going through TSA, it's not just sides that 2 00:00:03,160 --> 00:00:05,520 matters. I received a call from my mom 3 00:00:05,520 --> 00:00:11,200 who had what she thought was a very strange and probably pretty 4 00:00:11,200 --> 00:00:15,400 concerning experience going through airport security. 5 00:00:15,440 --> 00:00:19,840 She had her hands swabbed and she tested positive for a 6 00:00:19,840 --> 00:00:22,760 chemical that is used to make explosives. 7 00:00:23,080 --> 00:00:27,240 Jana, what are you up to? Well, today we are going to talk 8 00:00:27,240 --> 00:00:31,560 about the one ingredient that you should never use before 9 00:00:31,560 --> 00:00:35,120 going through airport security. Whether she made it to her 10 00:00:35,120 --> 00:00:38,440 international destination, I do not yet know, but hopefully. 11 00:00:57,480 --> 00:00:59,400 Hello everybody, and welcome back to another episode of 12 00:00:59,400 --> 00:01:01,160 Beauty by The Beaker. I'm Sadie. 13 00:01:01,240 --> 00:01:03,440 And I'm Natalie. And we're cosmonic chemists who 14 00:01:03,440 --> 00:01:05,680 are here to give science a hot new makeover. 15 00:01:05,720 --> 00:01:08,320 We sure are, because it's Wednesday and that's what we do. 16 00:01:08,400 --> 00:01:11,320 Every single Wednesday you can find us here giving science a 17 00:01:11,960 --> 00:01:18,600 really hot new makeover. Every every week until until 18 00:01:18,600 --> 00:01:22,040 that fateful day that we run out of storage on our external hard 19 00:01:22,040 --> 00:01:23,120 drive. So. 20 00:01:23,560 --> 00:01:28,000 So to prevent that from happening, please subscribe like 21 00:01:28,000 --> 00:01:29,800 comment. Share this with a friend Share 22 00:01:29,800 --> 00:01:32,640 this with a friend who's going to go on an airplane sometime 23 00:01:32,640 --> 00:01:35,480 soon. Yeah, have you ever considered 24 00:01:35,480 --> 00:01:39,640 that your cosmetics might get you stopped at TSA? 25 00:01:39,680 --> 00:01:42,280 Probably because we're all concerned about that with our 26 00:01:42,280 --> 00:01:45,760 size of our cosmetics, but maybe for other reasons. 27 00:01:45,960 --> 00:01:48,600 Oh. So there's more than just one 28 00:01:48,600 --> 00:01:51,000 quart size bag that I need to be concerned about. 29 00:01:51,080 --> 00:01:55,120 When you're going through TSA, it's not just size that matters. 30 00:01:57,120 --> 00:02:02,080 Tell me more. OK, so if you don't already 31 00:02:02,080 --> 00:02:06,440 know, I recently drove across the country from Utah to 32 00:02:06,440 --> 00:02:10,280 Kentucky, and then I went to because my father-in-law moved 33 00:02:10,280 --> 00:02:12,840 to Kentucky. Guys, it's such a long story. 34 00:02:12,920 --> 00:02:15,960 Have you ever heard of it? Where is it on a map? 35 00:02:15,960 --> 00:02:18,040 I can't point it out. It's above Tennessee, OH. 36 00:02:18,040 --> 00:02:21,160 OK, I can't point that one out. Either well, and Tennessee is in 37 00:02:21,160 --> 00:02:25,520 the South officially. And so then we went to Kentucky. 38 00:02:25,600 --> 00:02:27,280 Then we actually did go to Tennessee. 39 00:02:27,280 --> 00:02:30,880 And from Tennessee I flew to my home in Salt Lake. 40 00:02:30,960 --> 00:02:36,080 And while I was gone, my parents so graciously borrowed my dog, 41 00:02:36,080 --> 00:02:38,560 Owen Spalding. That is really nice of them. 42 00:02:38,560 --> 00:02:42,760 But they did it on the condition that the day after I returned, I 43 00:02:42,760 --> 00:02:45,800 would drive them to the same airport so that they could 44 00:02:45,800 --> 00:02:50,200 embark on their own expedition. Coincidentally, the scheduling 45 00:02:50,200 --> 00:02:52,800 just worked out this way. It was not that they booked a 46 00:02:52,800 --> 00:02:55,880 trip the day after, because that was their condition. 47 00:02:55,880 --> 00:02:57,840 It was just that. Like we're going to need a 48 00:02:57,840 --> 00:02:59,720 vacation after watching out. For a week. 49 00:03:00,160 --> 00:03:02,320 I wouldn't have blamed them if that was the case. 50 00:03:02,320 --> 00:03:04,960 Oh my God, me either. But it really just happened. 51 00:03:05,120 --> 00:03:08,080 The stars aligned that I was getting home the day before they 52 00:03:08,080 --> 00:03:10,040 left. But at any rate, I had to drive 53 00:03:10,040 --> 00:03:13,360 them to the airport, and shortly after I dropped them off, I 54 00:03:13,360 --> 00:03:17,960 received a call from my mom, who had what she thought was a very 55 00:03:17,960 --> 00:03:23,360 strange and probably pretty concerning experience going 56 00:03:23,400 --> 00:03:27,040 through airport security. Oh, did she bring more than a 57 00:03:27,040 --> 00:03:31,920 quart size bag of toilets? Well she is an over Packer but 58 00:03:31,920 --> 00:03:35,560 that is not why not the issue today while she was going 59 00:03:35,560 --> 00:03:40,280 through she was stopped and she had her hands swabbed and said 60 00:03:40,280 --> 00:03:44,120 she tested positive for a chemical that is used to make 61 00:03:44,120 --> 00:03:47,560 explosives. Jenna, what are you up to? 62 00:03:49,000 --> 00:03:53,240 Well, my first thought. Well, yeah, Potassium nitrate. 63 00:03:53,240 --> 00:03:56,320 Duh. To me, a cosmetic formulation 64 00:03:56,320 --> 00:04:01,400 chemist with extensive oral care experience, this came as no 65 00:04:01,400 --> 00:04:03,480 surprise. It was almost an expectation. 66 00:04:03,600 --> 00:04:05,240 Yeah, I'm like if. She'd come back negative. 67 00:04:05,240 --> 00:04:05,960 It would have been. Weird. 68 00:04:05,960 --> 00:04:08,760 Exactly. I said, well, yeah, duh, you use 69 00:04:08,760 --> 00:04:11,560 Sensodyne toothpaste. And she said, wait, what? 70 00:04:12,560 --> 00:04:14,240 Huh. You know about this? 71 00:04:14,280 --> 00:04:15,440 Yeah. And I said, does it? 72 00:04:15,440 --> 00:04:18,720 Everyone turns out maybe not. Oh. 73 00:04:18,959 --> 00:04:22,200 Well, tell the people. Well, today we are going to talk 74 00:04:22,200 --> 00:04:26,840 about the one ingredient that you should never use before 75 00:04:26,840 --> 00:04:30,760 going through airport security, potassium nitrate. 76 00:04:30,880 --> 00:04:33,520 Keep an eye out. So what is potassium nitrate? 77 00:04:33,680 --> 00:04:36,280 Common theme Atoms, Positive, negative. 78 00:04:36,400 --> 00:04:38,160 Like magnets, they stick together. 79 00:04:38,160 --> 00:04:40,960 We've talked about it before, but potassium nitrate, no 80 00:04:40,960 --> 00:04:43,440 different. This can be broken down into our 81 00:04:43,440 --> 00:04:47,480 positive and negative parts that magnetically attract to one 82 00:04:47,480 --> 00:04:50,120 another. There's the positive or cationic 83 00:04:50,360 --> 00:04:55,560 potassium ion and then a negative or anionic nitrate 84 00:04:55,760 --> 00:04:57,520 group. So I do like the. 85 00:04:57,600 --> 00:05:00,360 Potassium is positive and nitrate is negative. 86 00:05:00,400 --> 00:05:02,720 That's. Yeah, that is that. 87 00:05:02,840 --> 00:05:04,880 Works out so nicely. The universe did us a solid with 88 00:05:04,880 --> 00:05:05,760 that one. It really did. 89 00:05:05,840 --> 00:05:09,400 Or just human coincidence with naming and everything aligning 90 00:05:09,400 --> 00:05:11,360 in such a way that that happened to work. 91 00:05:11,960 --> 00:05:13,600 Out did you manifest that to be honest? 92 00:05:14,280 --> 00:05:19,320 Maybe so that word nitrate might ring a bell or two for some of 93 00:05:19,320 --> 00:05:23,880 you, because it does for me for more than just the fact that I 94 00:05:23,880 --> 00:05:26,800 am a chemist and deal with chemicals. 95 00:05:26,840 --> 00:05:29,560 But for me, the first thing that I think of when I think of 96 00:05:29,560 --> 00:05:33,680 nitrates is processed meat, because I remember a time when 97 00:05:33,680 --> 00:05:38,080 there was a big scare around nitrates in like salted and 98 00:05:38,080 --> 00:05:39,720 processed meat. Oh, interesting. 99 00:05:39,720 --> 00:05:42,240 I'm not sure if that's something that people are still like 100 00:05:42,240 --> 00:05:47,400 worried about in any probably. I'm sure that they are, but that 101 00:05:47,400 --> 00:05:50,840 is a modern day application of potassium nitrate as well. 102 00:05:51,080 --> 00:05:53,760 What does it do in meat? Great question. 103 00:05:53,920 --> 00:05:59,920 Nitrates are powerful oxidizers. What that means is when you what 104 00:05:59,920 --> 00:06:02,640 that mean? What that mean? 105 00:06:04,240 --> 00:06:09,080 What that mean is that if you heat it up, then it supplies 106 00:06:09,080 --> 00:06:10,160 oxygen. Essentially. 107 00:06:10,400 --> 00:06:13,360 If you put energy into it, then it can be a source of oxygen or 108 00:06:13,360 --> 00:06:16,120 an oxidizer. That means it can provide oxygen 109 00:06:16,120 --> 00:06:22,200 and when it's used in meats, it oxidizes the meat and you react 110 00:06:22,200 --> 00:06:24,920 it with the nitrates and it oxidizes it and changes the 111 00:06:24,920 --> 00:06:28,200 color of the meat to be red. So that's what we do now instead 112 00:06:28,200 --> 00:06:33,960 of using red 40 to dye meat. Crazy how the entirety of meat 113 00:06:33,960 --> 00:06:36,680 processing has been discussed on this podcast. 114 00:06:36,680 --> 00:06:40,080 Literally who knew this was a meat processing podcast? 115 00:06:40,080 --> 00:06:42,560 Literally because we also remember when we talked about. 116 00:06:43,040 --> 00:06:46,560 The jungle junk, Yes. Yeah, we've gone all the way 117 00:06:46,600 --> 00:06:47,680 from the beginning. It's crazy. 118 00:06:47,840 --> 00:06:51,680 That's been chronological too. That's. 119 00:06:51,920 --> 00:06:54,360 Kind of insane. Weird. 120 00:06:55,240 --> 00:06:57,400 Oh, OK. That's wild. 121 00:06:57,520 --> 00:06:59,200 Yeah, just. Wait till we start talking about 122 00:06:59,200 --> 00:07:04,640 petroleum in vegan alternatives, but that's a conversation. 123 00:07:06,240 --> 00:07:11,320 Nitrates are naturally occurring compounds made of nitrogen and 124 00:07:11,360 --> 00:07:15,360 oxygen, and they're found in soil, and they're crucial for 125 00:07:15,360 --> 00:07:18,160 plant growth. So if you are a human and you 126 00:07:18,160 --> 00:07:20,800 want a plant to growth, what might you do to it? 127 00:07:21,160 --> 00:07:24,080 What might you give it? Maybe I'd give it some food and 128 00:07:24,080 --> 00:07:27,520 water. Those are good things to give it 129 00:07:28,200 --> 00:07:30,880 another name for plant food fertilizer. 130 00:07:32,120 --> 00:07:36,320 So potassium nitrate or nitrates in general, very common 131 00:07:36,320 --> 00:07:39,320 ingredients in fertilizer. For potassium nitrate, it 132 00:07:39,320 --> 00:07:43,320 contains potassium and then the nitrate, which is nitrogen and 133 00:07:43,320 --> 00:07:45,840 oxygen. So potassium, nitrogen and 134 00:07:45,840 --> 00:07:50,200 oxygen, all of these are really essential atoms for plants to 135 00:07:50,200 --> 00:07:52,360 grow. They use all of these, so 136 00:07:52,400 --> 00:07:56,160 potassium nitrate. I'm going to say it's. 137 00:07:56,160 --> 00:07:58,040 Good. Yeah, good food source for 138 00:07:58,040 --> 00:07:59,520 plants 2. Thumbs up for Plant. 139 00:07:59,800 --> 00:08:02,840 But nitrates are also used for a variety of other things. 140 00:08:02,840 --> 00:08:06,480 The compound consists of 1 nitrogen atom and then three 141 00:08:06,480 --> 00:08:09,360 oxygen atoms. So when these molecules get 142 00:08:09,360 --> 00:08:13,880 excited, the oxygen, the oxygen atoms get a little bit Lucy 143 00:08:13,880 --> 00:08:17,840 Goosy. I Love Lucy Goosy. 144 00:08:19,640 --> 00:08:23,720 So the oxygens kind of come loose and this compound can 145 00:08:23,720 --> 00:08:28,080 decompose, but that results in like an oxygen output if you 146 00:08:28,080 --> 00:08:31,320 will. So for each compound, 3/4 of it 147 00:08:31,320 --> 00:08:34,720 is oxygen, right? Some of you may know a thing or 148 00:08:34,720 --> 00:08:36,480 two about oxygen. I know I need. 149 00:08:36,480 --> 00:08:40,240 It you do. But it can also hurt me it. 150 00:08:40,240 --> 00:08:45,520 Can, because pure oxygen is really reactive, like explosive, 151 00:08:47,120 --> 00:08:48,600 yeah. Interesting. 152 00:08:48,920 --> 00:08:51,400 You may know where I'm going. I could guess. 153 00:08:51,760 --> 00:08:56,960 Nitrates are the primary component in gunpowder and are 154 00:08:56,960 --> 00:08:59,800 used to make other explosives like fireworks. 155 00:09:02,000 --> 00:09:04,400 Yes, exactly. So like I mentioned, when 156 00:09:04,400 --> 00:09:06,880 they're heated, they give off oxygen. 157 00:09:06,920 --> 00:09:11,480 And we all know that a fire needs oxygen in order to burn. 158 00:09:12,040 --> 00:09:15,120 So nitrates can kind of be thought of as little like 159 00:09:15,200 --> 00:09:20,240 holding vessels for oxygen. It's like a stable oxygen tank 160 00:09:20,240 --> 00:09:22,920 that holds on to it until it's heated up. 161 00:09:22,920 --> 00:09:26,960 So then once you apply energy to it, you have these little oxygen 162 00:09:26,960 --> 00:09:30,440 tanks that open up, right? That results in an explosion. 163 00:09:31,040 --> 00:09:34,640 Yeah. Yeah, they're getting really 164 00:09:34,640 --> 00:09:37,680 loosey goosey, Yeah. They do, and it happens pretty 165 00:09:37,680 --> 00:09:40,880 fast when you have a bunch of them that process again, they're 166 00:09:40,880 --> 00:09:43,720 powerful oxidizers, right? And the same thing that makes 167 00:09:43,720 --> 00:09:47,160 them useful in explosives is what makes them useful in 168 00:09:47,160 --> 00:09:51,400 fertilizer and for curing meat. It's that they readily let go of 169 00:09:51,400 --> 00:09:54,600 those oxygens. They decompose with just you put 170 00:09:54,600 --> 00:09:56,760 in a little energy and it falls apart. 171 00:09:56,840 --> 00:09:59,440 And then you can use all those pieces for something else, which 172 00:09:59,440 --> 00:10:00,680 is great. It's really helpful. 173 00:10:01,120 --> 00:10:04,360 Yeah, just depends. Depends. 174 00:10:04,360 --> 00:10:06,680 Yes, definitely. But when you're going through 175 00:10:06,720 --> 00:10:11,600 airport security, part of the explosive Trace Detection 176 00:10:11,600 --> 00:10:19,640 testing or EDT is ETDETD. It doesn't matter is swabbing 177 00:10:19,640 --> 00:10:24,360 and testing for trace amounts of nitrates or explosive residue. 178 00:10:24,360 --> 00:10:27,960 Hmm, right. So interesting. 179 00:10:28,120 --> 00:10:30,640 Yeah. So as we have covered, nitrates 180 00:10:30,640 --> 00:10:35,120 are used, they're used daily by a lot of very innocent people, 181 00:10:35,640 --> 00:10:39,560 whether they are going about their day-to-day activities or 182 00:10:39,640 --> 00:10:42,080 maybe they're jet setting on new adventures. 183 00:10:42,160 --> 00:10:45,360 But today we're going to cover how you can limit your nitrate 184 00:10:45,360 --> 00:10:48,520 exposure before you hit your security checkpoint. 185 00:10:48,800 --> 00:10:51,160 Yeah, that is. Helpful. 186 00:10:51,880 --> 00:10:56,440 Because my mom somehow had elevated nitrates on her hands. 187 00:10:56,440 --> 00:10:58,760 What did they do though? Arrest her like or did. 188 00:10:58,960 --> 00:11:02,560 They had to search her entire luggage, so pulled everything 189 00:11:02,560 --> 00:11:06,600 out, swabbed all of her stuff. So luckily for her, the airport 190 00:11:06,600 --> 00:11:10,600 security line was short. Yeah, but this honestly could be 191 00:11:10,600 --> 00:11:14,000 kind of a big deal if you were in a hurry and you're like, I 192 00:11:14,000 --> 00:11:16,880 really wish I didn't use Sensodyne this morning because I 193 00:11:16,880 --> 00:11:21,040 happen to get swabbed and now I look like I am in pyrotechnics. 194 00:11:22,000 --> 00:11:23,920 Literally. And you have 20 minutes to get 195 00:11:23,920 --> 00:11:26,480 to your gate and you were hoping to pee before you got on the 196 00:11:26,480 --> 00:11:28,600 plane and now you can't. Exactly as. 197 00:11:28,760 --> 00:11:30,960 TSA is going through your. Whole bag. 198 00:11:31,080 --> 00:11:34,680 So yes, I mentioned that. My first thought was that it was 199 00:11:34,680 --> 00:11:38,400 my mom's Sensodyne toothpaste, which she did confirm on the 200 00:11:38,400 --> 00:11:39,880 phone that she had used that morning. 201 00:11:40,080 --> 00:11:42,560 Well, I would hope so. Imagine if she didn't. 202 00:11:43,800 --> 00:11:46,400 Yeah, then it'd be a bigger conversation. 203 00:11:46,920 --> 00:11:50,320 So how does potassium nitrate work in Sensodyne? 204 00:11:50,360 --> 00:11:53,240 Yeah, you may have guessed that the ingredient that I'm going to 205 00:11:53,240 --> 00:11:55,520 talk about again is potassium nitrate. 206 00:11:55,880 --> 00:11:59,160 Why wouldn't it be? You're like that conversation's 207 00:11:59,160 --> 00:12:02,160 over anyway. Sensodyne's totally different, 208 00:12:03,160 --> 00:12:05,200 has nothing to do. With that, throw everything out 209 00:12:05,200 --> 00:12:07,600 that we just talked about. No. 210 00:12:07,720 --> 00:12:12,440 So decreasing oral sensitivity or decreasing sensitivity, 211 00:12:12,680 --> 00:12:16,120 that's a drug claim. And so it's regulated by the 212 00:12:16,120 --> 00:12:18,640 FDA. In order for a product to claim 213 00:12:18,640 --> 00:12:22,760 that it's going to decrease sensitivity, it has to include 214 00:12:22,760 --> 00:12:26,080 an active ingredient that is monitored by the FDA. 215 00:12:26,560 --> 00:12:31,240 So in this case with Sensodyne toothpaste or any oral care 216 00:12:31,240 --> 00:12:36,160 product that claims to decrease sensitivity, it has to include 217 00:12:36,400 --> 00:12:41,360 potassium nitrate. But unlike our other examples 218 00:12:41,440 --> 00:12:45,560 for decreasing sensitivity, it's not the nitrate that we're 219 00:12:45,560 --> 00:12:49,560 using, but actually the potassium maybe, which we'll 220 00:12:49,560 --> 00:12:53,800 talk about that too. But the idea behind it is that 221 00:12:53,880 --> 00:12:58,200 once in your mouth, these potassium nitrate compounds can 222 00:12:58,280 --> 00:13:02,360 degrade, and then the potassium, the positively charged part, 223 00:13:02,440 --> 00:13:07,240 accumulates at the nerve endings and blocks the signals from 224 00:13:07,240 --> 00:13:10,680 going through. So then when hot, cold or sugary 225 00:13:10,680 --> 00:13:14,320 things come in contact with your teeth, you just don't receive 226 00:13:14,360 --> 00:13:17,400 the pain signal that you would before because your nerves are 227 00:13:17,400 --> 00:13:19,960 all plugged up with potassium. Interesting. 228 00:13:20,080 --> 00:13:21,880 It's like comedogenic for your gut. 229 00:13:22,000 --> 00:13:24,560 Kind of, yeah. But like, intentional, yeah. 230 00:13:25,280 --> 00:13:27,160 The type of comedogenicity we want. 231 00:13:27,160 --> 00:13:33,440 So Colgate carries a sensitivity relief toothpaste and from their 232 00:13:33,440 --> 00:13:37,000 website this is what they say potassium nitrate nitrate does 233 00:13:37,080 --> 00:13:39,120 in toothpaste. This is directly from their 234 00:13:39,120 --> 00:13:41,320 site. Potassium nitrate is a salt 235 00:13:41,320 --> 00:13:44,120 compound and a natural desensitizing agent. 236 00:13:44,440 --> 00:13:48,000 It blocks pain signals from your dental nerve to your brain so 237 00:13:48,000 --> 00:13:50,760 you don't feel any discomfort. By brushing your teeth with a 238 00:13:50,760 --> 00:13:53,280 toothpaste with potassium nitrate, you're coating your 239 00:13:53,280 --> 00:13:56,240 teeth with a solution that reduces pain and sensitivity. 240 00:13:56,400 --> 00:14:00,040 Potassium nitrate calms the tooth nerve activity so that you 241 00:14:00,040 --> 00:14:03,520 feel less discomfort when eating hot, cold, sweet or sticky 242 00:14:03,520 --> 00:14:07,560 foods. So that's what they're saying. 243 00:14:07,640 --> 00:14:11,520 Interesting theory, Yeah. But honestly, there's not like a 244 00:14:11,600 --> 00:14:13,440 lot of great data to back this up. 245 00:14:13,560 --> 00:14:17,160 I was kind of surprised how not great the data was to back it 246 00:14:17,160 --> 00:14:17,960 up. Really. 247 00:14:18,000 --> 00:14:20,240 Yeah, just. Given that it's an OTC 248 00:14:20,240 --> 00:14:22,760 regulator, yeah. And that it's like kind of the 249 00:14:22,760 --> 00:14:25,320 only one, right? But I did want to look into it a 250 00:14:25,320 --> 00:14:29,280 little bit and see on their website, they gave what looked 251 00:14:29,280 --> 00:14:33,200 like a lot of good information on potassium nitrate being a 252 00:14:33,200 --> 00:14:34,920 good ingredient. And everyone knows about 253 00:14:34,920 --> 00:14:36,960 Sensodyne toothpaste. Yeah. 254 00:14:36,960 --> 00:14:41,480 And I think it's pretty well like, this is exactly an example 255 00:14:41,480 --> 00:14:44,360 of how people don't actually care about studies to back up 256 00:14:44,360 --> 00:14:47,320 ingredients. As long as they assume that it's 257 00:14:47,320 --> 00:14:50,520 going to work, then they're on board with it working, right? 258 00:14:50,720 --> 00:14:53,960 I've never questioned the validity of sensitivity relief. 259 00:14:53,960 --> 00:14:56,240 Yeah, in oral care. Well, especially because they 260 00:14:56,440 --> 00:14:59,280 definitely do work, at least in my experience. 261 00:14:59,280 --> 00:15:01,880 Yeah, a lot of people I know like, use sensitivity 262 00:15:01,880 --> 00:15:04,160 toothpaste, and they have great results. 263 00:15:04,160 --> 00:15:06,400 So it's surprising that the data doesn't back it up. 264 00:15:06,400 --> 00:15:08,840 But this is kind of the best case scenario. 265 00:15:09,240 --> 00:15:11,240 Yeah, exactly. Yeah. 266 00:15:11,240 --> 00:15:15,000 And it's, again, that's not at all to say that that's not 267 00:15:15,000 --> 00:15:17,720 exactly what's happening. It could be that the mechanism 268 00:15:17,720 --> 00:15:19,840 described is exactly how it works. 269 00:15:20,200 --> 00:15:23,720 But at any rate, because it's what we like to do, let's talk 270 00:15:23,720 --> 00:15:25,840 about the study that this is kind of based on. 271 00:15:26,400 --> 00:15:30,040 Again, couldn't find a lot, but the best study that I found I'll 272 00:15:30,040 --> 00:15:33,640 link it here and it's one of those tests where they are kind 273 00:15:33,640 --> 00:15:37,040 of comparing using something to not using anything at all. 274 00:15:38,200 --> 00:15:43,920 O The test was comparing one group that was using a fluoride 275 00:15:43,920 --> 00:15:48,880 toothpaste in combination with a mouth rinse that contained 3% 276 00:15:48,880 --> 00:15:53,760 potassium nitrate and 90 parts per million sodium fluoride. 277 00:15:54,120 --> 00:15:57,760 OK. Then the control group was just 278 00:15:57,760 --> 00:16:00,680 using the toothpaste with fluoride? 279 00:16:01,480 --> 00:16:04,200 Why did they add in the sodium fluoride in? 280 00:16:04,560 --> 00:16:07,280 The potassium. Nitrate mouth threads well. 281 00:16:07,800 --> 00:16:12,640 As you've already identified, there are some issues with this 282 00:16:12,640 --> 00:16:16,040 study. For one, we're comparing using a 283 00:16:16,040 --> 00:16:21,400 mouth rinse that contains additional fluoride to using no 284 00:16:21,400 --> 00:16:25,640 mouth threads at all. Yeah, ideally, yes, the control 285 00:16:25,640 --> 00:16:29,600 group would have been using the exact same mouth rinse with the 286 00:16:29,600 --> 00:16:33,240 additional fluoride, just without the potassium nitrate. 287 00:16:33,240 --> 00:16:35,840 Yeah, kind of like the ketogenicity thing. 288 00:16:35,840 --> 00:16:39,960 We're testing tooth sensitivity. Yeah, it's subjective. 289 00:16:39,960 --> 00:16:44,920 It's subjective and we're not super blind to it because it's 290 00:16:44,920 --> 00:16:49,520 not like one group didn't know they were not using mouth rinse, 291 00:16:50,280 --> 00:16:52,800 right? Like we're not. 292 00:16:53,280 --> 00:16:57,920 Yeah, yeah. So some holes, some holes. 293 00:16:58,200 --> 00:17:00,720 Sometimes it's like, like, why not though? 294 00:17:00,720 --> 00:17:05,079 Like that was such an easy way to make the study so much more 295 00:17:05,079 --> 00:17:06,400 accurate. I don't know. 296 00:17:06,520 --> 00:17:12,599 And our results were that both groups saw significant decrease 297 00:17:12,599 --> 00:17:17,200 in sensitivity, but the group that used the mouse rinse saw an 298 00:17:17,560 --> 00:17:23,079 increased like more sensitivity, more or less sensitivity. 299 00:17:23,079 --> 00:17:27,560 Yeah, the the group that was using the mouth rinse had a 300 00:17:27,560 --> 00:17:31,640 greater decrease of their sensitivity, you know, but like. 301 00:17:31,640 --> 00:17:34,120 Who knows if it's because yes, potassium nitrate, it could 302 00:17:34,120 --> 00:17:35,080 just. Literally because. 303 00:17:35,120 --> 00:17:37,160 Using a mouth rinse contributes to that, yeah. 304 00:17:37,160 --> 00:17:40,280 It could be. And again, the mouth rinse and 305 00:17:40,280 --> 00:17:42,920 the toothpaste both had fluoride in it. 306 00:17:43,720 --> 00:17:47,920 My first thought is that because the mouth rants had additional 307 00:17:47,920 --> 00:17:51,560 fluoride that maybe it was that they were double dosing the 308 00:17:51,560 --> 00:17:55,480 fluoride whereas the other group was just getting one dose of the 309 00:17:55,480 --> 00:17:58,280 fluoride. It may have had nothing to do 310 00:17:58,280 --> 00:18:01,000 with the potassium nitrate because the toothpaste group 311 00:18:01,240 --> 00:18:04,920 that was just using that still saw a decrease in sensitivity. 312 00:18:05,240 --> 00:18:08,560 If it was like baseline there stayed completely the same and 313 00:18:08,560 --> 00:18:13,240 the other one had decreased, then like maybe that would be, 314 00:18:13,240 --> 00:18:16,240 you know, we still couldn't rule out that it was a passenium 315 00:18:16,240 --> 00:18:20,320 nitrate only, right? The other study that I saw that 316 00:18:20,320 --> 00:18:24,520 I didn't actually include here, but was LinkedIn. 317 00:18:24,520 --> 00:18:28,880 Some of the brand websites like Colgate's website was one where 318 00:18:28,880 --> 00:18:34,600 they basically concluded that 5% potassium nitrate decreases to 319 00:18:34,600 --> 00:18:39,280 sensitivity and higher concentrations due to OK. 320 00:18:39,480 --> 00:18:42,760 So it's like they tested higher concentrations and people 321 00:18:42,760 --> 00:18:47,320 reported that their sensitivity was decreased, but like so did 322 00:18:47,320 --> 00:18:50,600 the lower concentrations. Yeah, that was like the result. 323 00:18:50,840 --> 00:18:53,960 Interesting. Yeah, I was able to find those 324 00:18:53,960 --> 00:19:00,720 two studies, but yeah, this one was the best one and not like, 325 00:19:00,720 --> 00:19:03,600 awesome. Yeah, that's very interesting. 326 00:19:03,680 --> 00:19:06,320 Yeah. So could it have been that 327 00:19:06,320 --> 00:19:09,920 potassium nitrate was helping with tooth sensitivity? 328 00:19:10,200 --> 00:19:14,840 Certainly possible. But it also is probably a good 329 00:19:14,840 --> 00:19:18,600 idea to continue to use fluoride because that probably has a 330 00:19:18,600 --> 00:19:22,160 little bit more scientific backing than potassium nitrate 331 00:19:22,160 --> 00:19:24,680 even does. And you know, at the end of the 332 00:19:24,680 --> 00:19:27,160 day, whether or not this toothpaste is going to help with 333 00:19:27,160 --> 00:19:30,760 tooth sensitivity, it will increase your chances of being 334 00:19:31,200 --> 00:19:37,160 flagged through TSA. It will increase the amount of 335 00:19:37,160 --> 00:19:41,200 nitrates present that could be picked up in a swab. 336 00:19:41,440 --> 00:19:44,720 My mom had also mentioned that her TSA agent said something 337 00:19:44,720 --> 00:19:49,840 about like other hand creams or like baby products containing 338 00:19:49,840 --> 00:19:51,640 nitrates. I just wanted to dig a little 339 00:19:51,640 --> 00:19:54,840 bit deeper to find if there are any additional products that we 340 00:19:54,840 --> 00:19:59,120 need to be avoiding that have potassium nitrate in them or if 341 00:19:59,120 --> 00:20:01,640 oral sensitivity products are the only ones. 342 00:20:02,120 --> 00:20:05,400 And I was actually only able to find three more products. 343 00:20:05,760 --> 00:20:11,160 Oh, so they're definitely not common in cosmetics, but the 344 00:20:11,200 --> 00:20:13,680 other three products that I could find that did have 345 00:20:13,680 --> 00:20:18,160 potassium nitrate in them are the Estee Lauder Set and Refresh 346 00:20:18,160 --> 00:20:22,080 Perfecting Makeup Mist. Not entirely sure why it would 347 00:20:22,080 --> 00:20:24,840 have them. Maybe buffering, Yeah, maybe an 348 00:20:24,840 --> 00:20:28,080 active, not entirely sure. And then two products from 349 00:20:28,120 --> 00:20:32,600 Lemaire, the treatment lotion and the hand treatment, both of 350 00:20:32,600 --> 00:20:35,920 these contain potassium nitrate. Neither are like marked pocketed 351 00:20:35,920 --> 00:20:39,280 as it has this in it as an active ingredient. 352 00:20:39,280 --> 00:20:43,160 It's probably just in there because the formula was made 353 00:20:43,680 --> 00:20:46,360 using it because I mean, it's in fertilizer and stuff. 354 00:20:46,360 --> 00:20:47,840 It's going to help your hands grow, yeah. 355 00:20:48,720 --> 00:20:51,160 Exactly. You know, we don't know all the 356 00:20:51,160 --> 00:20:53,640 reasons, no. They could grow and become less 357 00:20:53,640 --> 00:20:55,760 sensitive. Maybe it's curing your meats, 358 00:20:56,720 --> 00:20:59,720 Your hands meats. My hands are really pink after. 359 00:20:59,880 --> 00:21:02,040 I use that lotion. So yeah, those were the only 360 00:21:02,040 --> 00:21:05,440 cosmetics that I could find that were not for oral care. 361 00:21:05,440 --> 00:21:09,440 So if I did miss any, you know of any other cosmetics that 362 00:21:09,440 --> 00:21:12,120 contain potassium nitrate, please let me know, drop them in 363 00:21:12,120 --> 00:21:16,040 the comments. But As for oral care, if it ever 364 00:21:16,040 --> 00:21:19,960 says anything about decreasing sensitivity, because that is a 365 00:21:19,960 --> 00:21:23,720 drug claim, we know for a fact that it is going to contain 366 00:21:23,840 --> 00:21:28,240 potassium nitrate. So maybe if you're in a hurry 367 00:21:28,440 --> 00:21:31,360 and you're going through the airport, skip that one that day. 368 00:21:31,400 --> 00:21:34,240 Yeah, don't use your oral sensitivity products. 369 00:21:34,400 --> 00:21:37,920 Yeah, I mean, the chances of you being stopped and swabbed are 370 00:21:38,240 --> 00:21:40,400 somewhat low, but. It I mean. 371 00:21:41,000 --> 00:21:45,000 It's enough that they will empty your suitcase and swab all your 372 00:21:45,000 --> 00:21:47,880 other things too. It's mostly just an annoyance. 373 00:21:47,880 --> 00:21:49,600 Yeah, you're not going. To get in trouble. 374 00:21:49,760 --> 00:21:55,040 But yes, yeah, obviously false negatives are a thing that they 375 00:21:55,040 --> 00:21:57,840 account for. The TSA agent didn't seemed like 376 00:21:58,120 --> 00:22:00,040 super shocked that this had happened. 377 00:22:00,040 --> 00:22:03,840 Yeah. And my mom obviously innocently 378 00:22:04,360 --> 00:22:07,440 going about her travels. Yeah, she's like, I have no clue 379 00:22:07,440 --> 00:22:11,240 what's going on, but at least if you ever do get swabbed TSA now 380 00:22:11,240 --> 00:22:13,840 you might not be confused about. Why, Yeah. 381 00:22:14,000 --> 00:22:16,160 Because yeah, I'd probably be like, what? 382 00:22:16,320 --> 00:22:18,000 What are you talking about? What did you find? 383 00:22:18,160 --> 00:22:22,040 Yeah, and maybe like your oral care products aren't a big deal, 384 00:22:22,040 --> 00:22:25,040 but have you ever thought about maybe don't spread fertilizer 385 00:22:25,040 --> 00:22:27,000 with your hands before going through TSA? 386 00:22:27,960 --> 00:22:30,240 I don't know if people are thinking about that, but that 387 00:22:30,240 --> 00:22:33,040 would probably be a bad idea. Me gardening 20 minutes before 388 00:22:33,040 --> 00:22:35,800 leaving for the airport, that is important. 389 00:22:36,000 --> 00:22:40,760 But yeah, I mean, if anything else, good to know that nitrates 390 00:22:40,760 --> 00:22:44,640 are what they're looking for and that nitrates do exist for just 391 00:22:44,640 --> 00:22:47,040 regular people all the time. Like, throughout your day, 392 00:22:47,040 --> 00:22:49,760 you're going to encounter them. Yeah, especially if you're a 393 00:22:49,760 --> 00:22:51,760 gardener like her of cured meats. 394 00:22:51,760 --> 00:22:55,240 Exactly, yes. But yeah, I just know, you know, 395 00:22:55,240 --> 00:22:58,200 summer's coming up. We're getting to that time where 396 00:22:58,200 --> 00:23:01,880 people are going to be hopefully traveling, going on some on 397 00:23:01,880 --> 00:23:04,840 their summer vacays, just. Setting a little bit. 398 00:23:04,960 --> 00:23:06,320 Yeah. So if you happen to find 399 00:23:06,320 --> 00:23:09,240 yourself going through an airport, maybe keep it in mind. 400 00:23:09,240 --> 00:23:13,200 Yeah, just a nice little PSA he might not have heard before. 401 00:23:13,400 --> 00:23:15,560 Yeah. Well that was so interesting. 402 00:23:15,560 --> 00:23:17,560 Thank you so much. I learned something new that was 403 00:23:17,560 --> 00:23:19,560 very fun. Well, I'm glad you did. 404 00:23:19,680 --> 00:23:22,840 And I'm so sad that your mom had such a harrowing experience at 405 00:23:22,840 --> 00:23:25,200 the Yeah. Luckily she got about through 406 00:23:25,200 --> 00:23:27,480 security. Whether she made it to her 407 00:23:27,480 --> 00:23:30,800 international destination, I do not yet know, but hopefully. 408 00:23:30,840 --> 00:23:35,240 You don't yet know still. No, I just, no, I don't. 409 00:23:36,040 --> 00:23:39,400 I should check. I told her to text me and now it 410 00:23:39,400 --> 00:23:41,040 has been some time. Yeah. 411 00:23:41,040 --> 00:23:44,320 Because yeah, they were direct, so they should be there by now. 412 00:23:44,320 --> 00:23:45,680 Yeah, they should. Hopefully. 413 00:23:45,680 --> 00:23:47,960 My mom didn't get stopped for her sensodyne. 414 00:23:48,680 --> 00:23:51,640 She got jailed. It may have been in her bag, I 415 00:23:51,640 --> 00:23:53,680 don't know. Potassium nitrate. 416 00:23:54,320 --> 00:23:57,360 She also likes to garden. Well anyway. 417 00:23:57,520 --> 00:23:59,600 Well, yeah.

Yeah, if you have an in at 433 00:24:55,440 --> 00:24:59,280 SanDisk, the four terabyte is probably better so that we don't 434 00:24:59,280 --> 00:25:02,000 have to start panhandling again soon. 435 00:25:02,080 --> 00:25:04,280 I mean and it's.

Yeah, they do make larger ones, 438 00:25:09,520 --> 00:25:13,440 but we'll cross that bridge. When I get to it, we can't get 439 00:25:13,440 --> 00:25:14,520 greedy.
