Description

Hydroxypropyl Guar is a chemically modified polysaccharide derived from guar gum, where hydroxypropyl groups are introduced to enhance its solubility and performance in aqueous systems. This modification significantly improves its stability, clarity, and compatibility with other formulation ingredients, making it a superior thickening, stabilizing, and film-forming agent. It is an essential ingredient for formulators in the personal care, oilfield, textile, and pharmaceutical industries seeking reliable, high-performance water-soluble polymers.

Application

• Personal Care & Cosmetics: Acts as a primary thickener, stabilizer, and conditioning agent in shampoos, conditioners, lotions, creams, and shower gels, providing excellent viscosity and a smooth sensory feel.
• Oilfield Drilling & Fracturing Fluids: Used as a viscosifier and fluid loss control additive in water-based drilling muds and hydraulic fracturing fluids to carry proppant and improve efficiency.
• Textile Printing & Sizing: Serves as a thickener in pigment printing pastes and a sizing agent for yarns, offering sharp print definition and easy wash-off.
• Pharmaceuticals: Employed as a binder, disintegrant, and controlled-release matrix former in tablet formulations, as well as a viscosity enhancer in topical gels and suspensions.
• Paper Manufacturing: Functions as a strength additive and retention aid, improving paper formation, dry strength, and filler retention.
• Food Industry (where specific grade compliant): Used as a thickener, stabilizer, and emulsifier in various food products, though specific food-grade certification must be confirmed.

Quality Control

Our Hydroxypropyl Guar is manufactured under a stringent quality management system. Each batch undergoes comprehensive testing for key parameters such as viscosity, moisture content, hydroxypropyl substitution level, and purity to ensure consistent performance and reliability. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
