Is Polyglyceryl-4 Caprate natural?

Yes. Both polyglycerol, from self-condensed glycerin, and capric acid, a coconut/palm C10 fatty acid, are natural-origin.

How we scored it

Polyglycerol-4 (glycerol tetramer, natural) esterified with capric acid (C10 fatty acid, natural/oleochemical); both natural building blocks → 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

Ester of tetraglycerin (a glycerol oligomer) with capric acid, typically derived from coconut or palm kernel oil. Fully oleochemical and glycerin-based.

In plain English

A mild emulsifier made from glycerin, linked into a small chain, and capric acid, a fatty acid typically from coconut or palm kernel oil. Helps blend oil and water in formulas.

CosIng definition: 1,2,3-Propanetriol, homopolymer, decanoates (1:1) (4 mol glycerol average molar ratio)
