Polyquaternium-4

Product Overview

Polyquaternium-4 is a specialized cationic polymer widely recognized in the personal care and cosmetic industries for its exceptional conditioning and film-forming properties. Chemically defined as a copolymer of hydroxyethyl cellulose and diallyldimethylammonium chloride, this ingredient delivers substantive benefits to hair and skin surfaces. Our manufacturing process ensures high purity and consistent molecular weight distribution, making it an ideal choice for formulators seeking reliable performance in rinse-off and leave-on products.

As a quaternary ammonium cellulose derivative, Polyquaternium-4 carries a positive charge that strongly adheres to negatively charged keratin surfaces. This substantivity provides long-lasting smoothness, detangling effects, and improved manageability without excessive buildup. The material is compatible with a wide range of surfactant systems and is frequently utilized in shampoos, conditioners, styling gels, and skin care lotions.

Key Features and Benefits

• Superior conditioning effect on damaged hair structures
• Excellent film-forming capabilities for enhanced hold
• Anti-static properties that reduce flyaway and frizz
• Compatible with anionic, nonionic, and amphoteric surfactants
• Improves wet and dry combing performance significantly
• Stable across a broad pH range commonly found in cosmetics

Technical Specifications

Industrial Applications

While primarily known for personal care applications, this versatile polymer serves multiple industrial functions. In cosmetic formulations, it acts as a primary conditioning agent that enhances the sensory profile of final products. Beyond hair care, it is employed in specialized surfactant systems where cationic modification of cellulose is required. Our R and D team supports custom modifications to meet specific viscosity or charge density requirements for niche applications including oilfield chemicals and specialized disinfectant formulations where quaternary ammonium functionality is needed.

Quality Assurance and Logistics

We maintain strict quality control protocols throughout the manufacturing lifecycle. Every batch undergoes rigorous testing for active content, viscosity, and microbial limits to ensure compliance with international standards. Certificates of Analysis (COA) are provided with every shipment. Our logistics network supports global delivery, with flexible packaging options including standard 25 kg drums or bulk containers tailored to customer requirements. Proper storage in a cool, ventilated environment ensures product stability and longevity.
