POLYQUATERNIUM-6
Is POLYQUATERNIUM-6 safe for seborrheic dermatitis?
Polyquaternium-6 keeps its lower-concern editorial label for seborrheic dermatitis. It reduces static, improves slip and leaves a light conditioning film, but it does not treat the condition.
A cosmetic safety assessment supports Polyquaternium-6 in covered uses and concentrations, with manufacturing controls for impurities. It is a water-compatible polymer rather than a fatty lipid, and no exact human seb derm or Malassezia concern was found. Build-up or the rest of a hair product can still feel uncomfortable, so rinse as directed and judge the whole formula.

What is POLYQUATERNIUM-6 used for in skincare?
Polyquaternium-6 is a positively charged polymer that attaches to negatively charged hair and skin surfaces. It acts as an antistatic conditioner and film former, improving combing and reducing a rough feel. It is often combined with surfactants, silicones, humectants and other conditioning polymers in shampoos, conditioners, body washes and styling products.
