Description

Rhamsan Gum is a high molecular weight, anionic heteropolysaccharide produced via microbial fermentation, known for its exceptional thickening and stabilizing properties. This biopolymer is valued for its ability to create high-viscosity, pseudoplastic solutions with remarkable stability across a wide range of pH, temperature, and salinity conditions. It is a critical functional ingredient for industries requiring superior rheology control, suspension, and emulsion stabilization in demanding environments.

Application

• Oil & Gas Drilling Fluids: Acts as a high-performance viscosifier and fluid loss control agent in completion, workover, and fracturing fluids, especially in high-temperature and high-salinity wells.
• Food & Beverage: Used as a thickener, stabilizer, and suspending agent in sauces, dressings, dairy products, and gluten-free baked goods to improve texture and shelf-life.
• Personal Care & Cosmetics: Provides excellent thickening and suspension in lotions, creams, shampoos, and toothpastes, offering a smooth, non-tacky feel.
• Industrial Applications: Serves as a binder, thickener, and film-former in ceramics, water-based paints, adhesives, and textile printing pastes.
• Pharmaceuticals: Utilized as a suspending agent, binder in tablet formulations, and a stabilizer in topical gels and ointments.
• Agriculture: Employed as a tackifier and suspending agent in pesticide and herbicide formulations to enhance adhesion and coverage.

Quality Control

Our Rhamsan Gum is produced under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for viscosity, purity, and microbiological quality. Certificates of Analysis (COA) detailing parameters such as assay, heavy metals, loss on drying, and microbial limits are provided with every shipment. We can supply grades compliant with Food Chemical Codex (FCC) and other relevant industry standards upon request.

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 opening to prevent caking and degradation due to moisture absorption.
