Description

Hair dye composition for the oxidative dyeing containing Camellia sinensis powder

The present invention relates to a hair dye composition for oxidation dyeing containing green tea powder. More specifically, the composition comprises a first agent containing an oxidizing dye precursor, a coupler and an alkali agent, and a second agent containing an oxidizing agent, wherein the first agent is an oxidation agent containing both green tea powder, a water-soluble antioxidant, and a reducing agent as an irritant. It relates to a hair dye composition for dyeing.

Generally, the composition for oxidation dyeing of keratin fibers including hair comprises a first agent containing an oxidized dye precursor and a coupler and a second agent containing hydrogen peroxide, and an oxidation condensation reaction is carried out between dyes through mixing before use. Penetration into the hair leads to color development.

In the process, the alkali agent contained in the first agent promotes the generation of perhydroxy anions through the mixing and use of the second agent containing the oxidizing agent, and the perhydroxy anion of the oxidant By causing melanin degradation, color and decolorizing effects are exhibited. However, as an unwanted side reaction, it reacts with the oxidant itself to form radicals, which degrade the hair protein and cause damage, thereby degrading the hair feel. In addition, an increase in pH due to an alkaline agent usually contained in the first agent to promote the oxidation reaction has a problem of causing scalp scalp and stimulating odor due to volatilizing property.

Various methods have been tried to improve the problem, and one of them is a method using the characteristics of antioxidant, anticancer, anti-inflammatory, antibacterial, and deodorant of green tea. In this regard, Patent Application No. 2001-0064665 'Composition for improving the scalp and hair condition' disclosed a composition capable of improving the scalp state through the inclusion of green tea extract, Patent Application 2005-0044901 'Contains green tea oil In the hair and scalp condition improvement composition 'discloses the effect of relieving inflammation by the hair dye for oxidative dyeing through green tea oil.
