Description

Polyquaternium-7 is a high-performance cationic polymer belonging to the quaternary ammonium compound family, widely recognized for its exceptional conditioning and film-forming properties. Its primary value lies in its ability to provide superior substantivity, manageability, and antistatic effects across a diverse range of formulations. This versatile ingredient is essential for manufacturers in the personal care, home care, and industrial sectors seeking to enhance product performance and stability.

Application

• Hair Care Formulations: A key conditioning agent in shampoos, conditioners, and styling products to improve wet combing, reduce static, and impart a soft, smooth feel.
• Skin Care & Cosmetics: Used in creams, lotions, and makeup as an emulsifier stabilizer and to enhance skin feel and texture.
• Liquid Soaps & Body Washes: Provides thickening and stabilizing properties while improving the skin's after-feel, reducing dryness.
• Household & Industrial Cleaners: Acts as a stabilizer and antiredeposition agent in laundry detergents and hard surface cleaners.
• Water Treatment: Employed as a flocculant and clarifying agent in process water and wastewater treatment systems.
• Textile & Leather Processing: Functions as a softener, antistatic agent, and dyeing auxiliary to improve fabric hand and process efficiency.
