Is Polyacrylate-5 natural? NOI 0.00

Q: Is Polyacrylate-5 natural?

Polyacrylate-5 has a Natural Origin Index (NOI) of 0.00 (scale 0–1) per ISO 16128. Styrene and both acrylate monomers are synthesised from petrochemical feedstocks; none has a natural-origin variant. An NOI of 0.00 means 0% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Copolymer of styrene, ethylhexyl acrylate, hydroxyethyl acrylate - all three monomers petrochemical (acrylates, EO-derived, styrene/benzene). 0/total=0.0 regardless of ratio.

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 film-forming copolymer built from petrochemical styrene and acrylate ester monomers. There is no natural-origin manufacturing route for any of its monomers.

In plain English

A film-forming synthetic polymer made from styrene and acrylate building blocks, all derived from petrochemicals. Used to leave a thin protective film on skin or hair.

CosIng definition: Copolymer of styrene, ethyl hexyl acrylate, hydroxyethyl acrylate monomers
