How we scored it
Decaglycerol (10 glycerin units, natural) esterified with 3 stearic acid (C18 oleochemical, natural) chains, losing only condensation water; C84H164O23, 1542 Da, all natural-origin atoms → 1542/1542 = 1.00.
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
Produced by esterifying vegetable-glycerin-derived decaglycerol with palm- or vegetable-sourced stearic acid (three ester bonds). Cosmetic-grade material is essentially always oleochemical.
In plain English
A thickening, skin-conditioning ingredient made by linking ten glycerin units together and attaching three stearic acid molecules, a fatty acid from vegetable oils. It gives creams a richer texture.
