Is Acrylates/Laureth-25 Methacrylate Copolymer natural? NOI 0.03

Q: Is Acrylates/Laureth-25 Methacrylate Copolymer natural?

Acrylates/Laureth-25 Methacrylate Copolymer has a Natural Origin Index (NOI) of 0.03 (scale 0–1) per ISO 16128. Synthetic acrylate backbone dominates; the one natural fragment (coconut lauryl chain) is heavily diluted by petrochemical EO and acrylate mass. An NOI of 0.03 means 3% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Backbone acrylic/methacrylic acid is petrochemical (0); laureth-25 methacrylate monomer is mostly EO mass (lauryl ~169 Da natural vs ~1,100 Da EO + ester). Ratio unspecified; overall natural share small.

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

Copolymerised from petrochemical acrylic/methacrylic acid and laureth-25 methacrylate (ethoxylated coconut lauryl alcohol esterified with methacrylic acid). Exact monomer ratio not given.

In plain English

A thickening polymer used in gels and lotions, mostly built from synthetic acrylic monomers with a small coconut-derived fatty component.

CosIng definition: Copolymer formed from laureth-25 methacrylate and one or more monomers of acrylic acid, methacrylic acid or one of their simple esters
