Description

Polyquaternium-31 is a high-performance cationic polymer belonging to the polyquaternium family of conditioning agents. This compound is valued for its exceptional ability to provide substantivity, film-forming, and antistatic properties, making it a key ingredient in advanced personal care formulations. It is primarily sought after by manufacturers in the cosmetics and hair care industries for creating premium rinse-off and leave-on products that require superior manageability and conditioning effects.

Application

• Hair Conditioners & Rinses: Acts as a primary conditioning agent, providing excellent detangling, softness, and shine to hair.
• Shampoos & 2-in-1 Products: Imparts conditioning benefits in cleansing systems, improving combability and reducing static flyaway.
• Leave-in Hair Treatments: Used in sprays, creams, and serums for long-lasting conditioning, frizz control, and heat protection.
• Skin Care Creams & Lotions: Functions as a cationic emulsifier and skin conditioning agent, enhancing texture and skin feel.
• Color Care & Anti-aging Hair Products: Helps protect hair color and improve the efficacy of active ingredients by increasing substantivity.
• Shaving Gels & Creams: Provides lubricity and a smooth after-feel on the skin.
