How we scored it
Ester of lauryl alcohol (C12, oleochemical, natural) and isostearic acid (C18 branched, oleochemical, natural); both natural building blocks → 1.00.
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 lauryl alcohol with isostearic acid, both typically produced from coconut/palm-kernel oleochemical feedstocks. No petrochemical alternative is in common cosmetic use.
In plain English
An emollient ester made by combining a coconut-type fatty alcohol (lauryl) with a plant/animal-derived branched fatty acid (isostearic acid). Gives creams and lotions a light, non-greasy skin feel.
Structure
dodecyl 16-methylheptadecanoate
