Mostly petroleum · ISO 16128

Is Polyacrylate-11 natural?

Mostly not. Sodium/sulfonate groups and the lauryl chain in one monomer are natural; the other acrylate, acrylamide and hydroxyethyl fragments are petrochemical.

INCI namePolyacrylate-11
FunctionEmulsion Stabilising · Opacifying
FeedstockA copolymer of petrochemical acrylate/acrylamide monomers together with…

How we scored it

5 monomers, ratios unspecified: Na-acryloyldimethyltaurate~0.45; Na acrylate~0.24; hydroxyethyl acrylate=0; lauryl acrylate (lauryl natural)~0.78; acrylamide=0. Unweighted mean~0.29.
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

A copolymer of petrochemical acrylate/acrylamide monomers together with a lauryl (coconut/palm) acrylate ester. Monomer ratios are not disclosed, so the value is an estimate.

In plain English

A synthetic copolymer of acrylate, taurate and lauryl-acrylate monomers, used to stabilise emulsions and make formulas look opaque.

CosIng definition: Copolymer of sodium acryloyldimethyl taurate, sodium acrylate, hydroxyethyl acrylate, lauryl acrylate, acrylamide monomers
