Application:
- Thickening Agent:Xanthan gum is used as a thickening agent in a variety of food products, including sauces, dressings, and soups, to improve texture and consistency. Pharmaceuticals: for thickening and stabilizing formulations;
- Stabilizer:It is used as a stabilizer in foods like ice cream, to prevent ice crystals from forming and improve texture.
- Suspension Agent: Xanthan gum is used as a suspension agent in liquid medications to prevent settling of particles.
- Cosmetics and Personal Care:Xanthan gum is used in cosmetics and personal care products as a thickening agent, stabilizer, and emulsifier.
- Oil and Gas Industry:Xanthan gum is used in drilling fluids to increase viscosity and help suspend solids.
Description:
Xanthan Gum is a high-performance polysaccharide produced through the fermentation of carbohydrates by Xanthomonas campestris bacteria. It appears as a light yellow powder, easily soluble in water, forming a stable, viscous solution even at low concentrations. Known for its excellent thickening, stabilizing, and suspending properties, xanthan gum performs well across a wide range of temperatures, pH levels, and salt concentrations.
Xanthan Gum – CAS No. 11138-66-2 | FAQ
Q1: What is xanthan gum and what are its main functions?
A: Xanthan gum (CAS No. 11138-66-2) is a natural, high-molecular-weight polysaccharide produced by the fermentation of carbohydrates. It functions as a thickener, stabilizer, and suspending agent, forming a stable viscous solution even at low concentrations and across a wide range of pH, temperature, and salinity levels.
Q2: How is xanthan gum used in the oil and gas industry?
A: In the oilfield sector, xanthan gum is widely used in drilling fluids to increase viscosity and suspend solids. This helps maintain hole stability, reduce fluid loss, and improve cuttings transport in both vertical and directional drilling. Moreover, its salt tolerance ensures consistent performance in seawater and brine-based systems.
Q3: What are the key technical specifications of xanthan gum?
A: It is a beige powder with pH 5.5–8.0 (1% solution), minimum viscosity of 1200 cps in 1% KCl, and strong shear-thinning properties. It retains rheological stability under extreme shear rates, temperature, and pressure, making it ideal for oil and gas chemical applications.
Q4: Can xanthan gum be used in other industries?
A: Yes. In addition to oilfield use, xanthan gum is widely used in food, pharmaceuticals, and personal care products as a thickener and stabilizer. It prevents separation in emulsions and suspensions, ensuring product consistency and shelf life.
