Description

Starch, Acetate Hexanedioate CAS NO 63798-35-6 is a chemically modified starch derivative, specifically an ester of starch with acetic and adipic acids. This modification imparts enhanced functional properties, making it a valuable ingredient for creating specialized material performance. It is particularly sought after for its ability to act as a biodegradable film-former and binder in demanding industrial and pharmaceutical applications. Key industries that utilize this compound include controlled-release drug delivery systems, advanced material coatings, and specialty adhesives.

Application

• Pharmaceutical Excipient: Used as a film-coating agent, binder, or matrix former in controlled-release and enteric-coated tablet formulations.
• Specialty Adhesives & Binders: Serves as a biodegradable and renewable binder in paper, textiles, and construction materials.
• Advanced Material Coatings: Functions as a key component in water-resistant and biodegradable coatings for packaging and films.
• Food-Grade Applications: Employed as a modified food starch (where compliant) for texture modification and stabilization.
• Encapsulation Matrix: Used for the microencapsulation of flavors, fragrances, or active ingredients for controlled release.
• Personal Care Products: Acts as a film-former and texture enhancer in cosmetic and personal care formulations.

Quality Control

Our Starch, Acetate Hexanedioate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for degree of substitution, viscosity, and purity, relevant to its intended application grade (e.g., Pharmaceutical, Food, or Technical). Certificates of Analysis (COA) documenting identity, assay, and key physical parameters are available for every shipment. We support compliance with relevant standards, including FCC for food-grade materials and cGMP guidelines for pharmaceutical applications.

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 container must be kept tightly sealed after each use to prevent moisture absorption and caking.
