Polyquaternium-67
What Polyquaternium-67 is & what it does
Polyquaternium-67 is a synthetic, cationic (positively charged) cellulose-based polymer. In cosmetic and sunscreen formulas it acts as a film former, viscosity-adjusting agent, and conditioner, helping the product deposit evenly and feel smooth. A notable property is that its positive charge lets it bind to skin and hair surfaces, which can improve the sensory finish and substantivity of a formula.

Polyquaternium polymers are commonly used conditioning agents in cosmetics and are generally considered well tolerated for topical use. Sensitivity varies by person, so patch testing is reasonable if your skin is reactive. We cannot offer medical advice, so consult a professional for specific concerns.
