AI Technical Summary

Technical Problem

Existing silicone oil emulsions have limitations in conditioning both healthy and damaged hair. Dimethyl silicone oil has a weaker conditioning effect on damaged hair, while amino silicone oil is not good at conditioning healthy hair and is prone to yellowing.

Method used

By modifying silicone oil with chitosan, and combining its cationic properties and biocompatibility, a modified silicone oil emulsion with both physical and charge adsorption mechanisms was prepared. The emulsion contains an emulsifier, deionized water, chitosan-modified silicone oil, a pH adjuster, and a preservative. The process was carried out at room temperature, avoiding heating.

Benefits of technology

It achieves good conditioning effects on both healthy and damaged hair, overcomes the limitations of traditional silicone oil, and features a simple and energy-efficient process suitable for industrial production, with high product safety and stability.

Abstract

The application relates to the field of silicone emulsions, in particular to a chitosan-modified silicone oil emulsion, a preparation method and application thereof, and contains the following components: an emulsifier, deionized water, chitosan-modified silicone oil, a pH regulator and a preservative; wherein the chitosan-modified silicone oil is prepared by reacting hydrogen-containing silicone oil with modified chitosan, the hydrogen-containing silicone oil is linear in structure and the Si-H bond is not at both ends of the molecular chain, the modified chitosan is obtained by amidation reaction of chitosan and long-chain alkenoic acid with terminal groups of carboxyl and alkenyl, the carbon number of the alkenoic acid is 3-11, and the alkenyl on the modified chitosan is grafted on the hydrogen-containing silicone oil in a branched chain form through a silicon hydrogen addition reaction. The cationic property and biocompatibility of chitosan are combined with the excellent smoothness of silicone oil by chitosan modification of the silicone oil, and the obtained modified silicone oil simultaneously has a physical adsorption and charge adsorption dual action mechanism.
