How we scored it

Stearic acid x3 (natural, oleochemical) + aluminium (natural mineral) -> whole salt 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Made by reacting three units of stearic acid, derived from vegetable oil or animal tallow, with an aluminium source. All fragments are natural-origin.

In plain English

An aluminium salt made from stearic acid, a fatty acid from vegetable oil or animal fat. Used in powders and cosmetics to reduce clumping and add body.
