Is Acrylates/Lauryl Methacrylate Copolymer natural?

Mostly not. The lauryl chain comes from coconut or palm-kernel fatty alcohol, while the acrylate and methacrylate backbones and comonomers come from petrochemical acrylic monomers.

How we scored it

Assumed 1:1 mol lauryl methacrylate (254.4 Da) : methyl methacrylate (100.1 Da). Natural lauryl C12H25 169.3 / 354.5 = 0.48; methacrylate backbones petrochemical. Comonomer ratio unknown.
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 copolymerises lauryl methacrylate, made from oleochemical C12 alcohol and methacrylate, with petrochemical acrylic monomers. Ziegler-synthesised lauryl alcohol would give 0.0 (supplier note), and the comonomer ratio varies by grade.

In plain English

A film-forming polymer that leaves a flexible, water-resistant layer on skin or hair. It is built from acrylic monomers, one of which carries a lauryl fatty chain usually taken from coconut or palm kernel oil.

CosIng definition: Acrylates/Lauryl Methacrylate Copolymer is a copolymer of Lauryl Methacrylate and one or more monomers consisting of acrylic acid, methacrylic acid or one of their simple esters
