How we scored it

Cholesterol (natural sterol) esterified with 12-hydroxystearic acid (natural, hydrogenated castor-oil derivative). Both fragments natural.
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 esterifying cholesterol, typically from lanolin, with 12-hydroxystearic acid derived from hydrogenated castor oil. Both feedstocks are natural/oleochemical.

In plain English

An emollient made by combining cholesterol, an animal-derived sterol, with hydroxystearic acid, a castor-oil derivative. Used in creams for a rich, skin-conditioning, thickening feel.
