Hydroxypropyltrimonium Hyaluronate

Product Description

Hydroxypropyltrimonium Hyaluronate is a professional-grade cationic derivative of Sodium Hyaluronate, engineered through proprietary synthesis at our state-of-the-art facility for superior stability and purity. By introducing a quaternary ammonium group to the hyaluronic acid backbone, this ingredient achieves a positive charge that ensures exceptional substantive binding to negatively charged biological surfaces such as hair fibers and skin membranes. As the global demand for "skin-cationic" and "rinse-off" conditioning technologies grows, this advanced polymer has become an essential commercial asset for premium personal care formulations.

Key Benefits & Applications

• Superior Biological Adhesion: Its cationic nature allows it to resist rinsing, making it highly effective in shampoos, conditioners, and facial cleansers for long-lasting hydration.
• Surface Repair & Film-Forming: Creates a breathable, protective film on the hair cuticle and skin stratum corneum, reducing trans-epidermal water loss (TEWL).
• Hair Vitality Enhancement: Significantly improves hair combability, reduces static electricity, and restores luster to chemically treated or damaged hair.
• Skin Softening: Provides a silky, non-greasy skin feel, often used in premium body washes and post-shave treatments.

Formulation Guidelines

• Recommended Usage: 0.1% – 2.0% depending on the desired intensity of hydration.
• Optimal pH Range: Stable and most effective within pH 5.0 – 7.0; adjust pH after incorporation.
• Processing: Gradually hydrate in the water phase with stirring to avoid clumping; heat stable up to 80°C.
• Compatibility: Excellent compatibility with most non-ionic and cationic surfactants; perform compatibility tests when using high concentrations of anionic thickeners.
• Synergy: Combine with Sodium Hyaluronate for multi-level hydration spanning from the skin surface to deeper epidermal layers.
