How we scored it
Where it comes from
Vinylpyrrolidone is synthesised from petrochemical acetylene- or formaldehyde-derived intermediates, and 1-eicosene is made by oligomerising petrochemical ethylene. No natural feedstock is used for either monomer commercially.
In plain English
A film-forming polymer used in hair styling products to hold style and add shine. It is built from two petrochemical building blocks, vinylpyrrolidone and a synthetic long-chain olefin.
CosIng definition: 2-Pyrrolidinone, 1-ethenyl-, polymer with 1-eicosene
