About

A cationic polymer that conditions hair and skin by forming a lubricating film that reduces static and improves texture.

Polyquaternium-59 is a quaternary ammonium-substituted vinyl polymer functioning as an antistatic agent and hair conditioner in cosmetic formulations. It is listed in the CosIng database without EU Annex II or III restrictions under Regulation EC 1223/2009. As a high-molecular-weight polymer, systemic absorption is negligible, and it is considered safe at typical use concentrations in leave-on and rinse-off products.

Skin benefits

  • Provides antistatic and conditioning effects on hair
  • Forms a lightweight film that improves skin feel
  • Improves wet combing and reduces breakage
