Description

Cationic Starch CAS NO 56780-58-6 is a chemically modified starch derivative where cationic groups are introduced onto the starch polymer backbone, imparting a positive charge. This modification is critical for enhancing the interaction with negatively charged surfaces and particles, making it a highly effective retention aid, flocculant, and strength additive. It is an essential material for industries such as paper manufacturing, water treatment, textiles, and personal care, where charge-based performance is required.

Application

• Paper Manufacturing: Primary use as a wet-end additive for improving fiber retention, drainage, and dry strength of paper and board.
• Water Treatment: Acts as an organic flocculant for clarifying process water and wastewater by aggregating suspended solids.
• Textile Sizing & Finishing: Used in warp sizing to protect yarns during weaving and as a finishing agent to improve fabric handle.
• Oilfield Drilling Fluids: Functions as a fluid loss control agent and shale stabilizer in water-based drilling muds.
• Personal Care & Cosmetics: Serves as a cationic conditioning agent in hair care products like shampoos and conditioners.
• Mining & Mineral Processing: Employed as a selective flocculant and dewatering aid in mineral slurry processing.
• Adhesives & Binders: Enhances the bonding properties and viscosity stability in corrugating and labeling adhesives.

Quality Control

Our Cationic Starch 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 charge density. Certificates of Analysis (COA) documenting purity, physical properties, and application performance are available upon request.

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 tightly sealed after use to prevent caking and degradation due to moisture absorption.
