What is eye shadow made of?


Well this is a cool question on many levels. I want to know what I am putting so close to my eyes, don't you?

Turns out, it is often made of a powder like talc (a very cool mineral often the main ingredient in baby powder) and mica, which is one of my favorite minerals. Yes, I have favorite minerals. Mica helps you identify certain rocks because it has nearly perfect cleavage, which means it breaks along an almost completely flat surface.

Anyway, according to wiki:
"Common ingredients in eye shadows consist of talcmicasericitemagnesium stearate, colorants, and preservatives. Fillers in eye shadows are primarily talc. The liquid binders are typically a silicone and the dry binders are typically magnesium stearate. In order to make an eye shadow, there has to be a balance between the fillers, dry binders and liquid binders. Once the ideal combination is found the shadow are pressed using 700-900psi."

aaaannnddd, that's what eye shadow is made of!
