Polyquaternium-1

Polyquaternium-1 (CAS 75345-27-6 ), also known as Polidronium chloride, is a cationic polymer used across personal care, water treatment, and industrial applications. It functions primarily as a preservative, conditioning agent, and surface modifier. The compound delivers antimicrobial activity and substantivity to treated substrates. In ophthalmic and contact lens care formulations, it acts as a preservative at low concentrations, offering broad-spectrum antimicrobial efficacy with good ocular tolerance. Personal care formulators incorporate it into shampoos and conditioners where it deposits onto hair and skin to improve texture and reduce static. In water treatment, it supports microbial control and aids in surface modification of process equipment. Textile and leather processors use it to modify fiber surfaces, improving dye uptake and imparting antistatic or softening effects to finished goods. This versatility makes it a staple in various chemical manufacturing sectors. Polyquaternium-1 is typically supplied as an aqueous solution, with active content concentrations varying by grade and supplier specification. Both cosmetic-grade and technical-grade material are available to meet specific requirements. Buyers should confirm active polymer content, counterion specification, and viscosity range when evaluating lots for formulation compatibility. Ensuring these parameters meet your internal standards is critical for consistent product performance. Contact us for supply of Polyquaternium-1 Request Quote
