      I wonder if there’s a random bored chemist that has a youtube channel just talking about what each ingredient in daily life items does

        I’ve actually come across this one in hematology, its used as a reagent in some analyzers to lyse red cells to release hemoglobin for direct measurement. source: I’m a lab tech.

          release hemoglobin for direct measurement

          This sounds like a really pretty way of saying “stabbing someone” at first brush, tbh lol

            lol, I guess its versatile. Red cells lyse fairly easily, if you just let them sit in water they’ll burst due to osmotic pressure (thats why we give people saline/salt water), this is just a really effective method of quickly bursting them I guess. The analyzers are pretty cool, when the dr orders a CBC/complete blood count its one instrument that measures hemoglobin, red cell indeces (red cell size, hemoglobin content, volume), platelets and a breakdown of your different white cell populations all within a few minutes. Blood is pretty cool, I’m not a vampire.

              Obviously not, you’re pretty clearly a ninja (i think lol). Also, I’m not gonna lie, this kinda fascinates me because science, but I also have a low key medical phobia kinda thing so it squicks me out a little at the same time lol. My SO is actually a scientist as well (not medical/bio, tho, thankfully lol she’s an environmental scientist) and I love it when she talks sci to me 😂🤣 so I even recognize like all of the words you used and everything

                Ya theres a very specific lingo. If she’s in environmental science I’d do all the water testing or whatever for chemicals, microbes. whenever they send stuff off to “the lab”, thats me!

        It isn’t. Soap is the salt of a fatty acid, sodium lauryl sulfate is a salt, but not of a fatty acid. Both are surfactants (meaning it breaks surface tensions), but have some different properties. A relevant difference in cosmetics is that SLS strips oils waaay better, which can damage your skin barrier and your hair. For some people it works fine, for others it’s too harsh and soap is better. (For me it damages my hair structure and thus makes my waves lackluster, but is fine in shower gel)

      Yeah I avoid it for this reason. Also for anyone looking for toothpaste without it.

      Sensodyne doesn’t have it but it’s expensive.

      Some of the Toms doesn’t but most does.

      I found out the cheap dollar tree sensitive toothpaste doesn’t have it either. So that’s what I use.

      It’s actually pretty hard to find toothpaste without it. Hope that helps.

        Every time I’m out looking for tooth paste I have to dig and dig for the one or two that don’t have that ingredient. It’s annoying as heck. Everything is fine and then you return from a vacation with a canker sore because the travel pack had it. I wanna sue somebody over this.

          boycott the fucking industry, you can get flouride from pills you suck on, and just brush your teeth more thuroughly and floss to make up for not using toothpaste.

          Every time I go to the dollar tree and it’s in stock I buy like 5 of them.

          Still less expensive than 1 tube of sensodyne.

          It’s not as minty. But does the job.

          Stock up when you find it.

          And yeah. I too will get sores even from using the regular kind for a few days. I think I’ve gotten more sensitive to it since I started avoiding it.

          My grand pappy swears that just brushing with baking soda (and water) is best. I tried that though and gagged on the taste and texture.

      I suppose a small child could swallow the cap of the toothpaste?

      Still pretty weird I don’t recall seeing this warning on toothpaste here in France. That being said we are big boys who are allowed to buy “Kinder Surprises”…

          But I didn’t mention Canada and can’t see any mention on Canada.

          I assumed it was obvious that it was about the US because they are known to have banned Kinder Surprises as a choking hazard.

              How on earth am I suppose to guess a toothpaste is located in Canada just looking at its composition?

              There isn’t either any obvious clues on the country of origin.

              Well nevermind, I’m glad you guys get to enjoy the wonder of opening a Kinder Surprise.

              Just know I will definitely use my French toothpaste unsupervised tonight. And there is nothing you can do to stop me.

                  My Canadian bro there is many countries who use both languages.

                  Especially on products labels it’s not like only Canada will do English French labels.

        Children could also swallow the toothpaste. Not a huge deal if they do it once but iirc it can be pretty dangerous in the long run

      In 2024, a documentary titled Seeking Mavis Beacon premiered at the Sundance Film Festival, which investigates the origin of Mavis Beacon. The creators of the film discovered that the image of a corporate-attired Black woman on the software packaging was not of someone named Mavis Beacon, but rather a Haitian model named Renee L’Esperance. She was paid $500 for posing for the marketing photo, wasn’t involved in the development or the sales of the software, and did not share in any of the presumably significant profits generated by the product. L’Esperance herself neither appears in nor is directly quoted in the documentary

      https://en.wikipedia.org/wiki/Mavis_Beacon_Teaches_Typing

      I never knew. I legit thought Mavis Beacon was a real person, the lady on the box, and I just never heard of her because I was a kid at the time and I never heard of a lot of things.

      Instead she’s a Haitian model who had nothing to do with the project aside from essentially being a gig worker at the right time.

      It’s like that woman who did the vocalizations for “Great Gig in the Sky”. Incredibly well known work for the entire rest of the world…just another paycheck for a pickup singer.
