Guar Hydroxypropyltrimonium Chloride Modified Guar Gum Cationic Guar CAS 65497-29-2

What Is Guar Hydroxypropyltrimonium Chloride? Definition & Chemical Properties

Guar Hydroxypropyltrimonium Chloride is a cationic guar gum derivative modified from natural guar gum. As a widely used water-soluble polymer, it combines the natural advantages of guar polysaccharide and cationic functional groups, delivering excellent thickening, conditioning, anti-static, emulsifying and film-forming properties.

This ingredient is easily dissolved in cold and hot water to form stable, transparent aqueous solutions. It features good compatibility with most surfactants, anionic, nonionic and amphoteric ingredients in cosmetic, personal care and industrial formulas. With mild performance, low irritation and outstanding adsorption capacity on hair, skin, fiber and solid surfaces, it has become an indispensable functional additive across personal care, textile, daily chemical and industrial fields. Different from common non-modified guar gum, its cationic structure brings stronger adhesion and conditioning effects, so it is preferred for high-performance formula development.

Key Advantages of Guar Hydroxypropyltrimonium Chloride

Guar Hydroxypropyltrimonium Chloride owns multiple superior properties compared with traditional thickeners and common cationic polymers. First of all, it has excellent hair conditioning performance: it can adsorb firmly on hair cuticles, reduce friction, improve combability, eliminate tangles and dryness after washing. Secondly, it provides obvious anti-static effect, effectively avoiding static flyaway of hair and textile fibers.

In formula application, it shows excellent compatibility with various surfactants and will not cause turbidity or stratification. It offers stable thickening effect without affecting the transparency of the final product. Besides, this modified guar derivative is mild to human skin and hair, with low irritation, meeting global cosmetic safety standards. For textile industry, it acts as a softener and finishing agent to enhance fabric smoothness and comfort. It is also biodegradable and eco-friendly, suitable for environmentally friendly daily chemical and industrial formulas.
