How we scored it

Assume all six free OH acylated, equal-molar acid mix, mean acyl 220 Da. Adipoyl C6H8O2 112.1 petrochemical; 2 diglyceryl C6H10O5 324.3 + 6 acyl 1321.1 natural; total 1757.5; 1645.4/1757.5 = 0.94.
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

Diglycerol from vegetable glycerin is esterified with adipic acid and then with caprylic, capric, isostearic, stearic and 12-hydroxystearic acids from coconut, palm and castor oils. Adipic acid is petrochemical (cyclohexane oxidation); bio-adipic acid is not commercially significant.

In plain English

A thick, glossy emollient oil that gives lipsticks, glosses and creams slip, shine and a soft feel. It is built from diglycerin and a mix of coconut and vegetable fatty acids, joined by adipic acid, which is made from petrochemicals.

CosIng definition: Hexanedioic acid, 3-(2,3-dihydroxypropyloxy)-2-hydroxypropyl diester, esters from reaction with a mixture of octanoic, decanoic, isooctadecanoic, octadecanoic and 12-hydroxyoctadecanoic acids
