Xanthan Gum E415/FCC Food/Iindustrial/Oil Drilling Petroleum Grade 80/200 Mesh Food Additives CAS11138-66-2 for Thickeners

Xanthan Gum is an extracellular polysaccharide produced by the fermentation of Xanthomonas campestris. It has unique rheological properties, such as high viscosity, good water - solubility, acid - alkali resistance and salt resistance, and is widely used in many industries such as food, petroleum and cosmetics as a thickener, stabilizer and emulsifier.

（ 1 ） Food Industry: It is an ideal thickener. In yogurt, it can make the texture rich and creamy, enhancing the taste. As a stabilizer, it can prevent the oil from separating out in baked goods and extend their shelf life. As an emulsifier, it can evenly disperse the cocoa particles in chocolate milk, preventing sedimentation.

（ 2 ） Pharmaceutical Field: It is often used as a binder in pharmaceutical preparations, tightly binding drug powders together to facilitate the production of tablets and capsules. It can also precisely control the drug release rate, and be made into sustained-release tablets to reduce the frequency of taking medications and improve patient compliance. In external ointments and gels, xanthan gum adjusts the consistency to ensure smooth application and uniform distribution of the active ingredients.

（ 3 ） Petroleum Extraction: During the extraction process, when xanthan gum is added to the drilling mud, it can increase the viscosity and shear force of the mud, effectively carrying cuttings and stabilizing the wellbore to ensure the smooth progress of the extraction. When applied in tertiary oil recovery, it can adjust the mobility of the injected water to displace more crude oil and improve the oil recovery rate.

（ 4 ） Other Industries: In cosmetics, it stabilizes the formulation and thickens the paste, providing a better application experience. In the paper industry, it improves the strength and surface smoothness of paper. In ceramic production, it improves the molding and drying properties of the ceramic body, reducing the defective rate.

(1)Thickening function: Xanthan gum can significantly increase the viscosity of liquids. A small amount of addition can greatly increase the viscosity of an aqueous solution, and its thickening effect is relatively stable under different temperature and pH conditions.

(2)Suspension and stabilization function: It can make insoluble solid particles evenly suspend in the liquid to prevent sedimentation. It can also inhibit the delamination of emulsions and keep the emulsion system stable.

(3)Emulsification function: It helps to reduce the surface tension at the oil-water interface, enabling oil droplets to be evenly dispersed in the water phase and forming a stable emulsion.

(4)Water retention function: With good hydrophilicity, xanthan gum can absorb and retain a large amount of water. In the food and cosmetics industries, it can prevent products from drying out and losing water, thus prolonging their shelf life.

(5)Improve rheological properties: It can endow fluids with good rheological properties. For example, it exhibits high viscosity under low shear force and reduces viscosity under high shear force. This characteristic gives it unique advantages in many industrial applications.
