Description

Dextrin Stearate is a modified carbohydrate derivative where stearic acid is esterified onto a dextrin backbone. This chemical modification imparts valuable amphiphilic properties, making it a versatile non-ionic surfactant and emulsifier. It is particularly sought after in the pharmaceutical and personal care industries for its ability to stabilize formulations and modify texture. Dextrin Stearate CAS NO 37307-33-8 serves as a key functional ingredient for manufacturers requiring biocompatible and effective surface-active agents.

Application

• Pharmaceuticals: Used as a binder, disintegrant, and emulsifying agent in tablet and capsule formulations.
• Cosmetics & Personal Care: Functions as a thickener, stabilizer, and opacifier in creams, lotions, and makeup products.
• Food Industry: Acts as an emulsifier and stabilizer in certain food-grade applications, though specific regulatory approval should be verified.
• Industrial Applications: Serves as a lubricant and release agent in polymer processing and other industrial manufacturing.
• Agrochemicals: Utilized as an adjuvant in pesticide and herbicide formulations to improve spreading and adherence.
• Textile Industry: Employed as a sizing agent and softener in fabric processing.

Quality Control

Our Dextrin Stearate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and performance consistency. While specific grades may vary, our standard quality commitment includes testing for parameters such as ester content, residual solvents, and heavy metals. Certificates of Analysis (COA) documenting these results are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at controlled room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
