Description

Cationic Starch Phosphate is a chemically modified starch derivative engineered to carry a positive ionic charge. This unique property makes it an exceptionally effective flocculant and retention aid in papermaking, while also serving as a powerful sizing agent and strength enhancer. It is a critical performance additive for industries requiring efficient solid-liquid separation and surface modification, including water treatment, textiles, and mining.

Application

• Papermaking Industry: Primary use as a wet-end additive for superior retention of fine particles and fillers, improving drainage, sheet formation, and dry strength.
• Water & Wastewater Treatment: Acts as an effective organic flocculant for clarifying process water and treating industrial effluents by aggregating suspended solids.
• Textile Sizing: Used as a cationic sizing agent to improve yarn strength, reduce breakage during weaving, and enhance fabric quality.
• Mining & Mineral Processing: Employed in solid-liquid separation processes, such as tailings dewatering and concentrate thickening, to improve sedimentation rates and clarity.
• Oilfield Applications: Functions as a fluid loss control additive and shale inhibitor in water-based drilling fluids.
• Personal Care & Cosmetics: Utilized as a cationic conditioning agent in hair care and skincare formulations for improved texture and feel.

Quality Control

Our Cationic Starch Phosphate is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance in key parameters such as degree of substitution, viscosity, and ionic charge density. While we offer standard industrial and papermaking grades, our quality control protocols can be aligned with specific customer requirements. Certificates of Analysis (COA) are provided with every shipment.

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 original container must be kept sealed to prevent caking and degradation from atmospheric moisture.
