How we scored it
Ester of isostearyl alcohol (Guerbet C18 branched alcohol) + lauric acid (C12H24O2); both oleochemical, 452.8/452.8 = 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
Isostearyl laurate is made by esterifying Guerbet-condensed isostearyl alcohol (from natural fatty alcohol feedstock) with lauric acid from coconut or palm kernel oil. Supplier verification is worthwhile given a possible petrochemical alcohol route.
In plain English
An emollient ester that conditions and softens skin, used in lotions and creams. Made by combining a branched fatty alcohol derived from plant oils with lauric acid from coconut or palm kernel oil.
Structure
16-methylheptadecyl dodecanoate
