Description

Guar Gum, 2-Hydroxyethyl Ether is a chemically modified polysaccharide derived from guar beans, designed to offer enhanced solubility and stability compared to native guar gum. This derivative is critical for applications requiring precise rheological control and consistent performance under varying pH and ionic conditions. It is an essential functional additive for industries such as food technology, personal care, oilfield services, and pharmaceuticals, where it acts as a superior thickener, stabilizer, and water-binding agent.

Application

• Food & Beverage: Used as a thickener, stabilizer, and emulsifier in sauces, dressings, dairy products, and gluten-free baked goods to improve texture and shelf-life.
• Personal Care & Cosmetics: Functions as a viscosity modifier and film-forming agent in shampoos, lotions, creams, and toothpaste for enhanced sensory feel and product stability.
• Oil & Gas Drilling Fluids: Serves as a key component in fracturing and drilling fluids to control fluid loss, reduce friction, and carry proppants.
• Pharmaceuticals: Employed as a binder, disintegrant, and controlled-release matrix agent in tablet formulations and topical gels.
• Textile Printing & Dyeing: Acts as a thickener in printing pastes to achieve sharp print definition and prevent dye migration.
• Paper Manufacturing: Utilized as a strength additive and retention aid to improve paper formation and dry strength.
• Construction Materials: Incorporated into cement and tile adhesives to improve water retention, workability, and adhesion.
• Agricultural Formulations: Used as a suspending agent and binder in pesticide and herbicide formulations for better coverage and efficacy.

Quality Control

Our Guar Gum, 2-Hydroxyethyl Ether is manufactured under a stringent quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent viscosity, purity, and substitution degree. We can supply material compliant with relevant standards such as FCC for food-grade applications. A comprehensive Certificate of Analysis (COA) detailing key parameters is provided with every shipment.

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 original container must be kept tightly sealed after use to prevent caking and degradation due to moisture absorption.
