Is Acrylates/Beheneth-25 Methacrylate Copolymer natural?

Mostly not. Mostly petrochemical acrylate/methacrylate backbone with a small natural behenyl fatty-alcohol side-chain linked via petrochemical ethylene oxide.

INCI nameAcrylates/Beheneth-25 Methacrylate Copolymer
FunctionViscosity Controlling
FeedstockA copolymer of acrylic/methacrylic acid monomers (petrochemical) with…

How we scored it

Assumed ~95:5 mol acrylate/methacrylate (petrochemical) : Beheneth-25 methacrylate macromonomer; macromonomer = behenyl-O 326Da natural + 25 EO + methacrylate 1170Da petrochemical → weighted ≈0.10 (ratio assumed, not given).
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 acrylic/methacrylic acid monomers (petrochemical) with a minor amount of Beheneth-25 methacrylate, a behenyl (coconut/palm fatty alcohol) chain ethoxylated with 25 mol petrochemical ethylene oxide. The exact monomer ratio is supplier-specific and was assumed here.

In plain English

A synthetic thickening polymer built mainly from acrylic/methacrylic acid units, with a small amount of behenyl (a fatty, coconut/palm-type) alcohol chain attached via an ethylene-oxide chain. Used to control viscosity in creams and lotions.

CosIng definition: Copolymer formed from the ester of 2-methylpropenoic acid and docosanol, ethoxylated, 25 mol EO (average molar ratio) and one or more monomers of acrylic acid, methacrylic acid or one of their simple esters
