Description

Xanthan Gum, Acetate is a high-purity, chemically modified derivative of the natural polysaccharide xanthan gum, where acetate groups are introduced to enhance specific functional properties. This modification is critical for applications requiring improved solubility, stability, or rheological control in challenging formulations. It serves as a vital functional additive for industries where precise thickening, stabilizing, and emulsifying performance is non-negotiable. Key sectors that rely on this specialized ingredient include advanced pharmaceutical delivery systems, high-performance personal care products, and specialized industrial applications.

Application

• Pharmaceutical Formulations: Acts as a stabilizer and controlled-release matrix agent in tablets, capsules, and topical gels.
• Cosmetics & Personal Care: Provides superior thickening and suspension properties in creams, lotions, shampoos, and serums.
• Food Science & Research: Used in specialized food-grade applications requiring modified rheology, such as in gluten-free baking or sauce stabilization.
• Industrial Applications: Functions as a viscosifier and stabilizer in water-based paints, coatings, adhesives, and ceramic glazes.
• Oilfield Chemicals: Employed in drilling muds and fracturing fluids for its enhanced rheological control under high-shear conditions.
• Agricultural Formulations: Used as a suspending agent and binder in pesticide and herbicide concentrates.

Quality Control

Our Xanthan Gum, Acetate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. We provide comprehensive Certificates of Analysis (COA) that detail key parameters such as degree of substitution, viscosity, and microbial limits. While produced to meet high-grade standards, specific compliance with FCC, USP/NF, or other pharmacopeial monographs can be confirmed upon request for your target application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept sealed to prevent absorption of atmospheric moisture, which can affect flow properties and stability.
