Is VP/Methacrylamide/Vinyl Imidazole Copolymer natural? NOI 0.00

Q: Is VP/Methacrylamide/Vinyl Imidazole Copolymer natural?

VP/Methacrylamide/Vinyl Imidazole Copolymer has a Natural Origin Index (NOI) of 0.00 (scale 0–1) per ISO 16128. All three monomers are petrochemical vinyl and acrylic building blocks, so no fragment of the polymer is natural in origin. An NOI of 0.00 means 0% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Copolymer of vinylpyrrolidone, methacrylamide (from acetone cyanohydrin) and 1-vinylimidazole (from imidazole and acetylene): all monomers petrochemical → 0/total = 0.0.

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

Vinylpyrrolidone, methacrylamide and vinyl imidazole from petrochemical acetylene, acetone and ammonia chemistry, polymerised together.

In plain English

A synthetic film-forming hair resin built from three petroleum-derived monomers; it has no natural-origin content.
