Is Butylated PVP natural?

No. N-vinylpyrrolidone monomer is synthesised from petrochemical butyrolactone/acetylene chemistry; butyl end-caps are also petrochemical.

How we scored it

Polyvinylpyrrolidone homopolymer with butyl end-groups; vinylpyrrolidone monomer and butyl groups are both petrochemical.
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

Made by polymerising N-vinylpyrrolidone, itself synthesised from petrochemical butyrolactone and ammonia, then partially butylated. No natural feedstock is involved.

In plain English

A film-forming synthetic polymer used in styling products to hold hair in place. Related to PVP but modified with butyl groups to resist humidity.

CosIng definition: 1-Vinyl-2-pyrrolidone, homopolymer, butylated
