Description

Guar Gum, Carboxymethyl Ether, Sodium Salt is a chemically modified polysaccharide derived from guar beans, designed to enhance solubility and performance in aqueous systems. This modification, known as carboxymethylation, significantly improves its thickening, stabilizing, and water-binding properties compared to native guar gum. It is an essential hydrocolloid for formulators in the food, pharmaceutical, personal care, and oilfield industries seeking reliable, high-performance rheology modifiers.

Application

• Food & Beverage: Acts as a thickener, stabilizer, and moisture retention agent in sauces, dressings, dairy products, and baked goods.
• Pharmaceuticals: Used as a binder, disintegrant, and controlled-release matrix in tablet formulations, and as a viscosity enhancer in liquid suspensions.
• Personal Care & Cosmetics: Provides viscosity control and stabilization in lotions, creams, toothpastes, and shampoos.
• Oil & Gas Drilling: Serves as a key component in fracturing fluids and drilling muds to control fluid loss and improve viscosity.
• Textile & Paper: Utilized as a sizing agent, thickener in prints, and for improving sheet formation and strength in paper manufacturing.
• Industrial Applications: Functions as a flocculant, binder in ceramics, and stabilizer in various aqueous-based industrial products.

Quality Control

Our Guar Gum, Carboxymethyl Ether, Sodium Salt is manufactured under a stringent quality management system. Each batch is tested to ensure it meets specifications for key parameters such as viscosity, degree of substitution, purity, and moisture content. We can supply material compliant with Food Grade (FCC) and other relevant standards as required. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee consistency and traceability.

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); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
