Physical Properties:

Quaternized copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate.PQ-11 is a high molecular weight product (average molecular weight ~ 1,000,000), supplied as a highly viscous, aqueous solution (20% solids).

PQ-11 forms clear, non-tacky, continuous films. PQ-11 cationic nature gives substantivity to hair, providing conditioning and bodying effects, with minimum build-up. PQ-11 improves wet and dry combability, gloss, smoothness and manageability of hair. PQ-11 is compatible with nonionic, anionic and amphoteric surfactants.
