Description

Starch, Sulfobutanedioate, Sodium Salt is a chemically modified starch derivative, specifically a sodium salt of a sulfosuccinate ester of starch. This modification imparts enhanced anionic character and water solubility, making it a valuable functional polymer. It is primarily utilized as a stabilizer, thickener, and emulsifying agent in demanding industrial and pharmaceutical formulations. Key industries that rely on this specialty starch include pharmaceuticals, personal care, and advanced material synthesis.

Application

• Pharmaceutical Excipient: Used as a disintegrant, binder, or stabilizer in tablet and capsule formulations.
• Personal Care & Cosmetics: Functions as a thickener, emulsion stabilizer, and sensory modifier in creams, lotions, and hair care products.
• Food Industry (where compliant): Acts as a modified food starch for texture modification and stabilization in specific food systems.
• Industrial Applications: Serves as a dispersant, viscosity modifier, or protective colloid in adhesives, coatings, and ceramic processing.
• Textile Sizing: Used in warp sizing formulations to provide lubrication and strength to yarns.
• Paper Coating: Enhances surface properties and acts as a binder in paper coating compositions.

Quality Control

Our Starch, Sulfobutanedioate, Sodium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets defined specifications for identity, purity, and functionality. While available in various grades (including technical and purer forms), we ensure consistent batch-to-batch performance. A comprehensive Certificate of Analysis (COA) detailing key parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent moisture uptake and caking.
