Description

Hydroxyethylamylopectin is a chemically modified starch derivative, specifically an ether derivative of amylopectin, a major component of starch. This modification enhances its solubility, stability, and functional properties, making it a valuable hydrocolloid and rheology modifier for demanding industrial applications. It is primarily utilized in sectors such as pharmaceuticals, food technology, and personal care, where consistent viscosity, texture, and binding performance are critical.

Application

• Pharmaceutical Formulations: Acts as a binder, disintegrant, and controlled-release matrix in tablet and capsule manufacturing.
• Food Industry: Functions as a thickener, stabilizer, and texturizing agent in sauces, dressings, and dairy products.
• Personal Care & Cosmetics: Used as a viscosity enhancer and film-forming agent in creams, lotions, and hair care products.
• Industrial Applications: Serves as a sizing agent in paper manufacturing and a thickener in water-based adhesives and coatings.
• Biomedical Research: Employed as a substrate or matrix in cell culture and tissue engineering studies.

Quality Control

Our Hydroxyethylamylopectin is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for substitution degree, viscosity, purity, and microbiological limits. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent moisture absorption, which can affect product performance.
