AI Technical Summary

Technical Problem

Hair damage caused by hydrogen peroxide remaining after hair dyeing and bleaching is a concern, and existing seaweed extracts do not effectively address this issue.

Method used

Enzymatic treatment of seaweed extract with an enzyme that oxidizes L-amino acids using oxygen as an electron acceptor, followed by removal of generated hydrogen peroxide with a scavenging agent, producing a seaweed extract with 2-oxoacid that can penetrate hair and neutralize residual hydrogen peroxide.

Benefits of technology

The enzyme-treated seaweed extract provides effective hydrogen peroxide removal and moisturizing effects, protecting and repairing hair by neutralizing hydrogen peroxide post-treatment, while also containing polysaccharides for additional benefits.

Abstract

To manufacture and provide a seaweed extract which is known to have good effects on hair and scalp such as a moisturizing effect, and is further imparted with a hydrogen peroxide-removing ability to increase its value.SOLUTION: The present invention is completed by discovering that by treating a seaweed extract with an enzyme having activity to oxidize L-amino acid using oxygen as electron acceptor and a hydrogen peroxide remover, even if a hydrogen peroxide-removing ability of the hydrogen peroxide remover used for the treatment is invalidated, an enzyme-treated seaweed extract with the hydrogen peroxide-removing ability can be produced.SELECTED DRAWING: None
