Description

Starch, Acetate Hexanedioate 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 films, coatings, and controlled-release matrices. It is particularly sought after by manufacturers in the pharmaceutical, food packaging, and specialty chemical industries seeking biodegradable and functional polymer alternatives. The compound is identified by CAS No. 68368-81-0.

Application

• Pharmaceutical Excipient: Used as a film-forming agent for tablet coatings and as a binder in controlled-release drug formulations.
• Edible Films & Coatings: Serves as a base material for biodegradable, edible packaging and protective coatings for food products.
• Specialty Adhesives: Employed in the formulation of remoistenable adhesives for labels, stamps, and envelopes.
• Textile Sizing: Acts as a biodegradable sizing agent to strengthen yarns during weaving processes.
• Paper & Board Coating: Enhances surface strength, printability, and grease resistance in paper and paperboard products.
• Microencapsulation: Functions as a wall material for encapsulating flavors, fragrances, or active ingredients.

Quality Control

Our Starch, Acetate Hexanedioate is produced under a rigorous quality management system. Each batch is tested to ensure it meets precise specifications for degree of substitution, viscosity, and purity, relevant for its target application grade (e.g., Food Grade per FCC or pharmaceutical standards). A comprehensive Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is available for every shipment.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
