Weekend Wonderings: Why so many emulsifiers in a commercial product, why we weigh essential oils, heating our phases, and creating a double boiler

by

In this post, Keisha asks: I’ve fallen in love with Laura Mercier’s Ambre Vanilla Souffle and was trying to replicate it. Looking at the ingredients, it seems like they might have used two different emulsifiers (glyceryl stearate & peg-100; cetearyl alcohol & polysorbate 60.) I’m curious, why would someone use two different complete emulsifiers?

Weekend Wonderings: Decyl glucoside in laundry detergents and greasiness of coconut oil in lotions with a quick note about e-mail

by

In this post on decyl glucoside, Mandy asks: Does anyone know if there is a powdered form of decyl glucoside? Or, is there another powdered surfactant that would work well as a laundry detergent?  I wouldn’t take the chance, to be honest.
