How we scored it
Where it comes from
Silica Silylate starts from natural amorphous silica (a mineral), whose surface silanol groups are then capped with petrochemical trimethylsilane to make the powder hydrophobic. The silica core dominates the mass.
In plain English
A silica (mineral) powder with its surface chemically treated to repel water, used to improve texture, prevent caking and stabilise emulsions in cosmetics.
CosIng definition: Amorphous silica, reaction products with trimethylsilane
