Description

Sodium Carboxyl Methylstarch is a chemically modified starch derivative, known for its superior thickening, stabilizing, and water-retention properties compared to native starch. This compound is essential for industries requiring precise viscosity control and enhanced product stability under varying pH and temperature conditions. It is a critical functional additive for manufacturers in the food, pharmaceutical, and personal care sectors seeking reliable, high-performance ingredients.

Application

• Food Industry: Acts as a thickener, stabilizer, and binder in sauces, gravies, soups, and dairy products, improving texture and shelf-life.
• Pharmaceuticals: Used as a disintegrant and binder in tablet formulations, and as a viscosity enhancer in topical gels and creams.
• Personal Care & Cosmetics: Functions as a rheology modifier and stabilizer in lotions, creams, and hair care products, providing a smooth, non-greasy feel.
• Paper Manufacturing: Employed as a wet-end additive and surface sizing agent to improve paper strength, printability, and ink holdout.
• Textile Industry: Serves as a sizing agent for warp yarns, providing abrasion resistance and facilitating weaving.
• Adhesives & Construction: Used as a thickener and water-retention agent in wallpaper pastes, ceramic tile adhesives, and cement-based mortars.

Quality Control

Our Sodium Carboxyl Methylstarch is manufactured under strict quality management systems. Each batch is tested to ensure it meets specifications for parameters such as degree of substitution, viscosity, pH, and purity. We can provide material compliant with standards including Food Chemical Codex (FCC) and relevant pharmacopeial monographs (e.g., USP/NF, Ph. Eur.) for specific grades. Certificates of Analysis (COA) are available upon request to guarantee traceability and batch-to-batch consistency.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking or degradation due to moisture absorption.
