FunctionCleansing · Emulsifying Surfactant
FeedstockPetrochemical C9-15 oxo alcohols esterified with phosphoric acid.

How we scored it

C9-15 alcohols are an odd-and-even-carbon oxo blend from petrochemical olefins (site policy): alkyl-O fragment ~185 Da (average C12H25O) petrochemical + phosphate cap PO3H2 81.0 Da (mineral, natural) = 266 Da; 81/266 = 0.30.
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.
