Description

Aminoethyl Cellulose is a chemically modified cellulose derivative, where aminoethyl groups are introduced onto the cellulose backbone, imparting cationic properties and enhanced reactivity. This modification is crucial for applications requiring controlled binding, flocculation, or surface modification due to its positive charge and affinity for anionic substances. It serves as a valuable functional biopolymer for researchers and manufacturers in the pharmaceutical, biotechnology, and specialty chemical industries seeking tailored polymeric materials.

Application

• Chromatography Media: Used as a cationic exchanger or support material for the purification of proteins, enzymes, and other biomolecules.
• Gene Delivery & Transfection: Acts as a non-viral vector or component in complexes for delivering nucleic acids into cells.
• Flocculation & Water Treatment: Employed as a cationic flocculant to aggregate and remove suspended anionic particles and organic matter from wastewater.
• Paper & Textile Manufacturing: Functions as a wet-strength additive, retention aid, or coating agent to improve product properties.
• Controlled Release Systems: Utilized in pharmaceutical and agrochemical formulations to create matrices for the sustained release of active ingredients.
• Enzyme Immobilization: Serves as a solid support for covalently binding enzymes, enhancing their stability and reusability in biocatalysis.
• Cosmetic & Personal Care: Incorporated into hair and skin care products as a conditioning agent and viscosity modifier.
• Adhesive & Binder Formulations: Used in specialty adhesives, coatings, and composites to improve binding strength and rheological properties.

Quality Control

Our Aminoethyl Cellulose is produced and tested under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure consistent performance, including assessment of degree of substitution, nitrogen content, viscosity, and purity. Certificates of Analysis (COA) detailing all relevant specifications are provided to guarantee compliance with your application requirements.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
