How we scored it

Pentaerythritol 136 (synthetic) esterified with 4x behenic acid 341 each (natural); fragments 1294 natural/132 synthetic, 1294/1426=0.91.
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 pentaerythritol, a petrochemical polyol, with four molecules of behenic acid from vegetable oil such as rapeseed. Behenic acid supplies most of the molecule's mass.

In plain English

A thickening emollient made by joining a small synthetic core to four long-chain fatty acid molecules from vegetable oil. It adds body and a smooth texture to creams.
