How we scored it
Decaglycerol (from glycerin) 1.0 and isostearoyl chains (from oleic acid) 1.0; ester adds no foreign mass; 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 polymerises vegetable glycerin to decaglycerol and esterifies it with isostearic acid from clay-catalysed oleic acid isomerisation. Epichlorohydrin-based polyglycerol is not commercially significant.
In plain English
An oil-loving emulsifier and emollient that helps blend oil and water and leaves skin feeling soft. It combines polyglycerin from vegetable glycerin with a branched fatty acid from vegetable oleic acid.
CosIng definition: Pentaester of decaglycerol and isostearic acid
