Description

Guar Gum, 2-Hydroxy-3-Sulfopropyl Ether is a chemically modified polysaccharide derived from guar beans, designed to offer enhanced solubility and stability compared to native guar gum. This anionic derivative is valued for its superior thickening, suspending, and stabilizing properties in demanding aqueous systems. It is an essential functional additive for industries requiring precise rheology control and compatibility with electrolytes, including personal care, oilfield chemicals, textile printing, and construction materials.

Application

• Personal Care & Cosmetics: Acts as a primary thickener and stabilizer in shampoos, shower gels, lotions, and creams, providing excellent skin feel and salt tolerance.
• Oilfield Drilling Fluids: Used as a viscosifier and fluid loss control agent in fracturing and completion fluids, offering high-temperature stability.
• Textile Printing: Serves as a highly effective thickener for pigment printing pastes, ensuring sharp print definition and wash-fastness.
• Construction & Building Materials: Functions as a water retention agent and workability aid in cement-based products like tile adhesives and grouts.
• Paper Manufacturing: Enhances sheet formation, strength, and retention of fillers and fines in the wet-end process.
• Industrial Coatings & Adhesives: Provides rheological control and prevents sagging in water-based formulations.
• Agriculture: Used as a binder and dispersant in pesticide and fertilizer formulations.
• Pharmaceuticals (Excipient Grade): Employed as a binder, disintegrant, and controlled-release matrix in tablet formulations.

Quality Control

Our Guar Gum, 2-Hydroxy-3-Sulfopropyl Ether is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for viscosity, degree of substitution, pH, and moisture content. We provide comprehensive Certificates of Analysis (COA) upon request and can supply grades compliant with relevant industry standards for cosmetics, food contact, and industrial applications.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent caking and degradation due to moisture absorption.
