How we scored it
Citric acid (fermentation, natural) esterified with 3x isostearyl alcohol (branched C18 oleochemical from oleic-acid isomerisation, natural). All-natural building blocks = 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 esterifying citric acid, produced by fermenting sugars, with isostearyl alcohol, a branched fatty alcohol made by isomerising natural oleic acid. No significant petrochemical route exists for isostearyl alcohol.
In plain English
An emollient that softens and conditions skin. It's made by combining citric acid, produced by fermenting sugar, with a fatty alcohol derived from plant oils.
Structure
tris(16-methylheptadecyl) 2-hydroxypropane-1,2,3-tricarboxylate
