Surfactants: Cleansing descriptions and increasing mildness – analyzing surfactants

Thanks for sticking around to the end of this series. I know for some this might seem like a very dry subject and some of you are yelling at the screen for me to shut up about chemistry stuff and get to the formulas, but if you have a curious mind and want to learn...

Chemistry: Rheology modifiers – categories and defining a few more terms

On September 7th, we started this series off by looking at why xanthan gum might pill or ball on your skin when used in lotions. Then we started this series, for which I’ve also created a glossary of terms as we’ll be using them a lot in the future… Defining some scientific terms: Solubility, viscosity,...
