How we scored it
Behenic acid C22H44O2 (natural, oleochemical, e.g. rapeseed) + calcium (natural mineral counter-ion) -> 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 behenic acid, a fatty acid typically derived from rapeseed or other vegetable oils, with a calcium source. Both the fatty acid and the calcium ion are natural-origin.
In plain English
A calcium salt of a fatty acid derived from vegetable oil such as rapeseed. It is used in powders and pressed cosmetics to prevent clumping and add opacity.
Structure
calcium docosanoate
