AI Technical Summary

Technical Problem

Existing cationic polysaccharide conditioners require a large amount of water and solvent purification during the preparation process, and the product has poor biodegradability, making it difficult to meet environmentally friendly requirements. At the same time, they contain harmful substances, which affects their application in personal care products.

Method used

Cationic tamarind gum is used as the main ingredient, and the conditioning agent is prepared by reacting it with (3-chloro-2-hydroxypropyl)trimethylammonium chloride under alkaline conditions, avoiding water or solvent purification steps, and the cationic substitution degree is controlled between 0.02 and 0.27. (2,3-dihydroxypropyl)trimethylammonium chloride and ash are added to ensure biodegradability.

Benefits of technology

A conditioning agent that achieves high biodegradability and excellent conditioning properties, suitable for personal care and home care products, reduces environmental pollution and maintains rheological properties.
