AI Technical Summary

Technical Problem

Existing hair lightening compositions, particularly those using persulfate, often result in undesirable yellowish-orange tones and degrade the quality of hair fibers, making it difficult to achieve a natural lightening effect while maintaining fiber quality and compatibility with dyeing processes.

Method used

A composition comprising hydrogen peroxide as a chemical oxidizing agent, carbonates or bicarbonates, silicates, and specific hydrocarbon compounds, along with amphoteric or zwitterionic compounds, esters, amides, and organic amines, which is applied to keratin fibers to achieve lightening while minimizing yellowing and preserving fiber quality.

Benefits of technology

The composition effectively lightens keratin fibers with reduced yellowing, providing a more natural result and maintaining the quality of the hair fibers, while also being compatible with direct and oxidative dyes for simultaneous bleaching and dyeing.
