Description

Xanthan Gum CAS NO 11138-66-2 is a high-molecular-weight polysaccharide produced through the fermentation of sugars by the bacterium *Xanthomonas campestris*. This versatile biopolymer is prized for its exceptional ability to thicken, suspend, and stabilize aqueous systems even at low concentrations. It is a critical functional ingredient for manufacturers in the food and beverage, oilfield, pharmaceutical, and personal care industries seeking reliable rheology control and texture enhancement.

Application

• Food & Beverage: A key thickener, stabilizer, and emulsifier in sauces, dressings, dairy products, gluten-free baked goods, and beverages to prevent ingredient separation and improve mouthfeel.
• Oilfield Drilling Fluids: Used in water-based drilling muds to control viscosity, suspend cuttings, and reduce fluid loss, enhancing drilling efficiency and wellbore stability.
• Pharmaceuticals: Employed as a suspending agent in liquid formulations, a binder in tablets, and a stabilizer in emulsions and creams.
• Personal Care & Cosmetics: Functions as a thickener and stabilizer in lotions, creams, shampoos, and toothpastes to provide desired consistency and shelf-life.
• Industrial Applications: Used in adhesives, ceramics, paints, and agrochemicals as a rheology modifier and water-binding agent.
• Animal Feed: Acts as a binder and stabilizer in wet and dry pet food formulations.

Quality Control

Our Xanthan Gum is manufactured and tested to meet stringent quality standards, including Food Chemicals Codex (FCC) and USP-NF specifications where applicable. Every batch undergoes rigorous analytical testing for parameters such as viscosity, microbial limits, heavy metals, and identification. A Certificate of Analysis (COA) is provided with each shipment to ensure traceability and compliance with your specific requirements.

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 original container tightly sealed to prevent caking and degradation due to moisture absorption.
