How we scored it
C16-18 fatty alcohol (oleochemical, natural) esterified with phosphoric acid (mineral, natural); condensation water uncounted, both fragments natural = 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
Cetearyl alcohol (cetyl+stearyl, typically palm/coconut-derived) esterified with phosphoric acid. Cosmetic-grade cetearyl alcohol is assumed oleochemical, though synthetic Ziegler/oxo-alcohol supply exists so confirm supplier route.
In plain English
An emulsifier that helps oil and water mix in creams and lotions. It's made from plant-derived fatty alcohol (from palm or coconut oil) combined with mineral phosphoric acid.
