Description

Starch, 2-(Diethylamino)Ethyl Ether, Hydrochloride is a cationic, water-soluble starch derivative where the hydroxyl groups of the starch polymer are partially substituted with 2-(diethylamino)ethyl ether groups, subsequently converted to the hydrochloride salt. This chemical modification imparts a positive charge, making it a valuable cationic polymer for applications requiring binding to negatively charged surfaces. It is primarily utilized in the paper manufacturing, textile processing, and water treatment industries as a flocculant, retention aid, and sizing agent.

Application

• Paper Manufacturing: Acts as a cationic wet-end additive to improve fiber retention, drainage, and sheet strength.
• Textile Industry: Used as a cationic sizing agent for yarns and as a finishing agent to improve fabric handle and dye uptake.
• Water Treatment: Functions as an organic flocculant for clarifying process water and wastewater by aggregating suspended solids.
• Cosmetics & Personal Care: Serves as a cationic conditioning agent in hair care formulations and skin creams.
• Pharmaceuticals: Employed as a cationic binder or disintegrant in tablet formulations and as a component in controlled-release systems.
• Adhesives & Binders: Used in the formulation of specialty adhesives where cationic charge is beneficial for substrate bonding.

Quality Control

Our Starch, 2-(Diethylamino)Ethyl Ether, Hydrochloride is produced under a rigorous quality management system. Each batch is tested to ensure consistent performance characteristics such as degree of substitution, charge density, viscosity, and purity. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory needs.

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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
