Where it comes from
Polyquaternium-2 is produced by polymerising a urea-based diamine (from petrochemical urea and dimethylaminopropylamine) with bis(2-chloroethyl) ether. No natural-origin route exists for this synthetic polymer.
In plain English
An antistatic, film-forming polymer used in hair products. It's built from synthetic building blocks: a urea-based diamine and a chlorinated ether crosslinker.
