How we scored it
Diglycerin (glycerin dimer, natural, CosIng 'oxybis(propanediol)') esterified with poly-12-hydroxystearic acid (self-condensed castor-oil-derived acid, natural) -> 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
Made from diglycerin (two linked glycerin units) esterified with self-condensed 12-hydroxystearic acid, derived from castor oil. Both feedstocks are plant-derived.
In plain English
A water-in-oil emulsifier used in long-wear makeup and sunscreens. It's made from glycerin and a castor-oil-derived fatty acid chain, both plant-based.
CosIng definition: Octadecanoic acid, 12-hydroxy-, homopolymer, ester with oxybis(propanediol)
