Description

Carboxymethyl Cellulose Ammonium Salt is a water-soluble, anionic cellulose ether derivative, known for its excellent thickening, suspending, and film-forming properties. This compound is particularly valued for its enhanced compatibility and performance in formulations requiring a cationic counterion. It serves as a critical functional additive in diverse industries, including pharmaceuticals, personal care, and industrial processes, where controlled viscosity and stabilization are paramount.

Application

• Pharmaceutical Formulations: Used as a binder, disintegrant, and stabilizer in tablet manufacturing, and as a viscosity modifier in topical gels and ophthalmic solutions.
• Personal Care & Cosmetics: Functions as a thickener, emulsion stabilizer, and film former in shampoos, lotions, creams, and toothpaste.
• Industrial Applications: Acts as a water retention agent, thickener, and protective colloid in ceramic glazes, adhesives, and textile printing pastes.
• Food Industry (where compliant): Employed as a thickener, stabilizer, and dietary fiber in various food products.
• Agriculture: Used in pesticide and herbicide formulations as a dispersant and suspending agent.
• Paper & Coatings: Serves as a surface sizing agent and coating additive to improve strength and printability.

Quality Control

Our Carboxymethyl Cellulose Ammonium Salt is manufactured under a stringent quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent performance, purity, and safety. Certificates of Analysis (COA) documenting key parameters such as assay, degree of substitution, viscosity, and moisture content are available upon request. We can support compliance with relevant standards for pharmaceutical (USP/NF), food (FCC), and industrial applications.

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 after opening to prevent caking or degradation due to moisture absorption.
