Description

Scleroglucan is a high molecular weight, non-ionic polysaccharide biopolymer produced by fermentation of the fungus *Sclerotium rolfsii*. This compound is valued for its exceptional rheological properties, providing high viscosity and stability across a wide range of temperatures, pH levels, and salinities. It serves as a critical performance additive in demanding industrial applications where superior thickening, suspension, and water control are required. Key industries that utilize scleroglucan include oilfield services, cosmetics, and food technology.

Application

• Enhanced Oil Recovery (EOR) & Drilling Fluids: As a viscosifier and fluid loss control agent in high-temperature, high-salinity reservoir conditions.
• Cosmetics & Personal Care: Used as a natural thickener, stabilizer, and film-forming agent in creams, lotions, and serums.
• Food Industry: Functions as a thickener, stabilizer, and texturizing agent in various food products, often where syneresis control is needed.
• Pharmaceuticals: Employed as an excipient in controlled-release drug delivery systems and topical formulations.
• Industrial Coatings & Adhesives: Acts as a rheology modifier to control flow and sag resistance.
• Ceramics & Cement Slurries: Provides suspension and water retention properties.

Quality Control

Our scleroglucan is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of viscosity, purity, and microbial load. Certificates of Analysis (COA) detailing specific batch results are available upon request. Production can be aligned with relevant standards for target industries, including food-grade (FCC) specifications.

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 moisture absorption and caking.
