Description

Polyquaternium-7 is a high-performance cationic polymer belonging to the polyquaternium family of conditioning agents. This versatile compound is valued for its exceptional ability to provide superior conditioning, antistatic properties, and film-forming capabilities in aqueous systems. It is a critical ingredient for formulators in the personal care, home care, and industrial chemical sectors seeking to enhance product performance and stability.

Application

• Hair Care Formulations: A primary conditioning agent in shampoos, conditioners, and hair styling products, providing excellent detangling, softness, and manageability.
• Skin Care & Cosmetics: Used in creams, lotions, and liquid soaps as a conditioning and viscosity-modifying agent to improve skin feel and product texture.
• Household & Industrial Cleaners: Functions as a stabilizer and antistatic agent in hard surface cleaners, car wash formulations, and fabric softeners.
• Water Treatment: Acts as a flocculant and clarifying agent in process water and wastewater treatment applications.
• Textile & Leather Processing: Employed as a softening, antistatic, and dye-leveling auxiliary in finishing baths.
• Pet Care Products: Incorporated into pet shampoos and conditioners for its gentle yet effective conditioning properties.
