Description

Starch, Oxidized is a chemically modified carbohydrate derived from native starch, where controlled oxidation introduces carboxyl and carbonyl groups, significantly altering its functional properties. This modification is critical for enhancing performance in demanding industrial applications where native starch falls short, such as providing superior binding strength, improved viscosity stability, and excellent film-forming characteristics. It is an essential raw material for manufacturers in the paper, textile, construction, and food industries seeking consistent, high-performance additives.

Application

• Paper Manufacturing: Used as a wet-end additive and surface sizing agent to improve sheet strength, printability, and ink holdout.
• Textile Industry: Serves as a warp sizing agent to protect yarns during weaving, offering easy desizing and excellent film flexibility.
• Construction Materials: Functions as a binder and rheology modifier in gypsum boards, wallboard joint compounds, and ceramic tile adhesives.
• Food Industry (where compliant): Acts as a thickener, stabilizer, and binder in sauces, soups, and bakery fillings, providing a clear, stable paste.
• Adhesives & Corrugating: A key component in water-based adhesives, including those for corrugated cardboard, due to its strong adhesion and fast tack.
• Pharmaceuticals: Employed as a disintegrant, binder, or film-coating agent in tablet formulations.
• Personal Care: Used in cosmetics and personal care products as a thickener, stabilizer, and texture enhancer.

Quality Control

Our Starch, Oxidized is manufactured under a stringent quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent performance in your application. Parameters typically monitored include carboxyl content, viscosity, pH, moisture, and whiteness. A Certificate of Analysis (COA) documenting these results is provided with every shipment. We can supply grades suitable for various standards, including food-grade (FCC, EU directive) and technical specifications.

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 original container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption. Keep away from strong oxidizing agents.
