Is Acrylates/C5-8 Alkyl Acrylate Copolymer natural? NOI 0.00

Q: Is Acrylates/C5-8 Alkyl Acrylate Copolymer natural?

Acrylates/C5-8 Alkyl Acrylate Copolymer has a Natural Origin Index (NOI) of 0.00 (scale 0–1) per ISO 16128. Acrylic monomers derive from propylene, and the C5-8 alkyl groups come from petrochemical oxo alcohols such as 2-ethylhexanol. An NOI of 0.00 means 0% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Acrylic acid, methacrylic acid and their esters (C5-8 alkyl groups from oxo alcohols) are all petrochemical; no natural fragment. 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

Free-radical polymerisation of acrylic acid, methacrylic acid and alkyl acrylates, all from petrochemical propylene and oxo alcohols. No bio-based route is commercial for cosmetic grades.

In plain English

A synthetic acrylic polymer that forms a flexible, water-resistant film and thickens or stabilises emulsions. It is used in sunscreens, styling products and creams to improve texture and hold.

CosIng definition: Acrylates/C5-8 Alkyl Acrylate Copolymer is the copolymer of C5-8 alkyl acrylate and one or more monomers of acrylic acid, methacrylic acid, or one of their simple esters
