  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.

  Very fancy way of saying soap

    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)
