Polyquaternium-67
In Skincare: Is Polyquaternium-67 Safe? Comedogenic Rating & Side Effects
Safety Information
Overview
Ingredient Profile
Role of Polyquaternium-67
Active Cosmetic Mechanisms
ANTISTATIC
Static EliminatorReduces static electricity and flyaway hair
SCIENTIFIC ANALYSIS
// Evidence: Antistatic agents neutralize electrostatic charges through cationic surfactants (quaternary ammonium compounds like behentrimonium chloride) or conductive polymers that increase surface conductivity to dissipate charge or attract moisture. The mechanism involves forming a conductive film on fiber surfaces, neutralizing charge buildup. Particularly effective on damaged hair with raised cuticles.
FILM FORMING
Protective Coating AgentCreates a continuous thin layer on surfaces
SCIENTIFIC ANALYSIS
// Evidence: Film-forming polymers create continuous, cohesive coatings after solvent evaporation or chemical crosslinking. These include natural polymers (shellac, chitosan), synthetic polymers (acrylates copolymers, PVP/VA copolymer, polyurethanes), and modified natural polymers. Film formation involves spreading, solvent evaporation, polymer chain interpenetration, and coalescence. Film properties depend on glass transition temperature, molecular weight, and plasticizer content.
HAIR CONDITIONING
Hair SoftenerImproves hair manageability, softness, and appearance
SCIENTIFIC ANALYSIS
// Evidence: Hair conditioning ingredients smooth the cuticle, reduce frizz, and add shine through cationic surfactants (behentrimonium chloride), silicones (dimethicone, amodimethicone), natural oils, and proteins. These deposit on negatively charged damaged sites, neutralizing charge, filling surface irregularities, and providing lubrication. Mechanism involves electrostatic attraction, film formation, and surface smoothing.

Does it clog pores?
Whether Polyquaternium-67 clogs pores depends on the formulation and concentration.
Is Polyquaternium-67 safe for skin?
Polyquaternium-67 has a safety rating of 2 out of 5. A rating of 2 means it is generally considered safe for most skin types. Note: Polyquaternium-67 is considered safe for use in cosmetics by the Cosmetic Ingredient Review (CIR) Expert Panel at concentrations up to 1%. Limited safety data suggests it has low potential for skin pe
Is Polyquaternium-67 good for sensitive skin?
Polyquaternium-67 tolerance on sensitive skin varies by individual.
What are the side effects of Polyquaternium-67 in skincare?
Known considerations: Polyquaternium-67 is considered safe for use in cosmetics by the Cosmetic Ingredient Review (CIR) Expert Panel at concentrations up to 1%. Limited safety data suggests it has low potential for skin penetration and is generally non-irritating, though it may cause mild ocular irritation upon contact.
