How we scored it
Oleoyl (olive acyl proxy) C18H33O 265 + decyloxy C10H21O 157 = 423 Da (C28H54O2); both fragments oleochemical, so 423/423 = 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
Dominant route esterifies olive-oil fatty acids with coconut- or palm-kernel-derived n-decanol. Petrochemical Ziegler decanol exists, so a supplier note applies, but cosmetic grades are assumed oleochemical.
In plain English
A light, silky emollient ester made from decyl alcohol and fatty acids from olive oil, which softens skin and spreads easily. Olive oil supplies the acid; decyl alcohol is normally made from coconut or palm kernel oil.
CosIng definition: Fatty acids, olive oil, n-decyl esters
