Description

Sodium Dicarboxycellulose is a water-soluble, anionic cellulose derivative produced by the controlled oxidation of cellulose. This compound is valued for its excellent thickening, stabilizing, and water-retention properties, making it a versatile functional additive. It is primarily used in industries such as personal care, pharmaceuticals, textiles, and construction where rheology modification and binding are critical.

Application

• Personal Care & Cosmetics: Acts as a thickener, stabilizer, and film-forming agent in shampoos, lotions, creams, and toothpaste.
• Pharmaceuticals: Used as a binder, disintegrant, and viscosity-enhancing agent in tablet formulations and topical gels.
• Textile Industry: Serves as a sizing agent and thickener in printing pastes for fabrics.
• Construction & Building Materials: Functions as a water-retention aid and workability improver in cement-based products like tile adhesives and grouts.
• Food Industry (where compliant grades are available): Can be used as a stabilizer and thickener in certain food products.
• Paper Manufacturing: Employed as a dry-strength additive and coating agent to improve paper quality.
• Detergents & Cleaners: Enhances viscosity and stabilizes formulations in liquid soaps and cleaning products.
• Ceramics: Acts as a binder and plasticizer in ceramic body formulations and glazes.

Quality Control

Our Sodium Dicarboxycellulose is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets defined specifications for purity, viscosity, and functionality. A Certificate of Analysis (COA) is provided with every shipment, detailing key parameters. We can supply grades compliant with relevant industry standards, including food-grade (where applicable) and pharmaceutical excipient guidelines.

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 and degradation due to moisture absorption.
