Polyquaternium-7: Advanced Conditioning Agent for Hair and Skin Care.

Polyquaternium-7 is a water-soluble, cationic copolymer composed of acrylamide and diallyldimethylammonium chloride. This highly charged, clear, viscous liquid is renowned for its conditioning and film-forming properties in hair and skincare formulations. It enhances texture, smoothness, and manageability in hair care products, while providing a velvety feel to skin care products without greasiness.

Key Features & Benefits

• Superior Conditioning: Reduces dryness, imparts moisture, and enhances hydration.
• Improved Hair Texture: Provides slip for easy detangling and improved combability in both wet and dry conditions.
• Film-Forming: Forms a thin, substantive layer on hair and skin, locking in moisture for lasting hydration.
• Compatible with Surfactants: Works well with anionic surfactants in shampoos, body washes, and other cleansers, stabilizing foam and increasing viscosity.
