Is Acrylates/Polytrimethylsiloxymethacrylate Copolymer natural? NOI 0.00

Q: Is Acrylates/Polytrimethylsiloxymethacrylate Copolymer natural?

Acrylates/Polytrimethylsiloxymethacrylate Copolymer has a Natural Origin Index (NOI) of 0.00 (scale 0–1) per ISO 16128. Both the variable acrylate/methacrylate monomers and the silicone methacrylate dendritic monomer are petrochemical or silicone by rule; no natural fragment. An NOI of 0.00 means 0% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Acrylic/methacrylic acid or ester monomers (petrochemical, 0) copolymerised with dendritic silicone methacrylate monomer (silicone, 0). 0.00.

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

Manufactured by free-radical copolymerisation of petrochemical acrylic/methacrylic monomers with a dendritic trimethylsiloxy methacrylate silicone monomer. No natural-origin route exists for either component.

In plain English

A synthetic film-forming polymer used in hair styling products and skin creams to hold shape and improve feel. It combines acrylic and silicone building blocks, both petrochemical in origin.

CosIng definition: Copolymer formed of the dendritic monomer polytrimethylsiloxymethacrylate and one or more monomers consisting of acrylic acid, methacrylic acid, or one of their simple esters
