How we scored it
Stearyl alcohol C18H38O (natural, oleochemical) esterified with lactic acid C3H6O3 (natural, fermentation), losing H2O - both fragments natural, whole ester 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.
