Description

Dextran Hydroxypropyltrimonium Chloride is a cationic derivative of dextran, a biocompatible polysaccharide, modified with hydroxypropyltrimonium chloride groups. This modification imparts a permanent positive charge, making it a highly effective conditioning and film-forming agent for personal care and pharmaceutical applications. It is primarily sought by formulators in the cosmetics, hair care, and biomedical industries for its ability to improve substantivity, manageability, and biocompatibility in various products.

Application

• Hair Care Products: As a substantive conditioning agent in shampoos, conditioners, and hair masks to improve combability, reduce static, and enhance shine.
• Skin Care Formulations: Used in creams, lotions, and serums for its film-forming and moisturizing properties, providing a smooth skin feel.
• Color Cosmetics: Improves the adherence and longevity of pigments in mascaras, eyeliners, and foundations.
• Pharmaceutical Topicals: Acts as a bioadhesive and viscosity-modifying agent in gels, ointments, and transdermal delivery systems.
• Biomedical Coatings: Utilized for surface modification of medical devices or cell culture substrates to enhance biocompatibility.
