About

A widely used cationic conditioning polymer in shampoos and body washes. CIR-cleared and generally safe; the residual acrylamide-monomer question is what keeps it short of green.

Skin benefits

  • Conditioning polymer for hair and rinse-off products
  • Reduces static and improves wet combing
  • Forms a soft film on skin in cleansers

Known concerns

  • Cationic polymer; small risk of acrylamide monomer residuals
  • Can build up on hair with heavy use
  • Sensitization is rare but reported
