Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a decolorizing composition, especially a decolorizing composition for hair and body hair.

[0002]

2. Description of the Related Art Depigmenting agents are widely used for hair or body hair, and under alkaline conditions, hydrogen peroxide oxidizes and decomposes melanin in hair to decolorize hair lightly. As the dosage form of the decolorizing agent, there are many two-part types in which a first part containing an alkaline agent and a second part containing hydrogen peroxide are mixed at the time of use. ,
There is also a multi-drug type with three or more agents.

[0003]

However, the depigmenting agent chemically decolorizes hair by oxidation under weakly alkaline to alkaline conditions. This polymerization is a fairly vigorous reaction, and has the drawbacks that the moistness, smoothness and gloss are lost, and the hair loses its elasticity and stiffness due to protein elution and the like. Therefore, improvements have been desired in these points.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to minimize damage to the hair after the bleaching treatment. Particularly, it is to provide a decolorizing composition capable of maintaining firmness and elasticity.

[0005]

Means for Solving the Problems As a result of intensive studies to achieve the above-mentioned object, the present inventors have found that a protein hydrolyzate and an amino acid derivative are blended with a decolorizing agent.
It has been found that the above problems can be solved. That is, the decolorizing agent of the present invention contains a protein hydrolyzate, an amino acid and / or
Alternatively, it is characterized by containing an amino acid derivative.

The protein hydrolysates used in the present invention include keratin protein hydrolysates, collagen protein hydrolysates, silk protein hydrolysates, elastin protein hydrolysates and the like, one of which is Two or more kinds are used, and among these, keratin protein hydrolyzate is particularly preferable. As the amino acid and / or amino acid derivative, glycine, alanine, valine, leucine, serine, threonine, phenylalanine, tyrosine, aspartic acid, asparagine, cysteine, histidine, arginine, glutamine, pyrrolidonecarboxylic acid or one of these salts Alternatively, two or more kinds are used, and of these, pyrrolidonecarboxylic acid or a salt thereof is particularly preferable. In the decolorizing composition of the present invention, protein hydrolysis and the amount of amino acid and / or amino acid derivative are not particularly limited as long as the effects of the present invention can be obtained,
The blending amount can be appropriately adjusted and used, but the protein hydrolyzate is preferably 0.001 to 20% by weight, more preferably 0.01 to 5% by weight, and the amino acid and / or the amino acid derivative is 0.001 to 1% by weight. It is 20% by weight, more preferably 0.01 to 5% by weight.

The blending amount of the alkaline agent is not particularly limited as long as it is within the range generally used for a decolorizing agent.

Further, in the decolorizing composition of the present invention,
Since the hydrolyzed protein product is mixed with the amino acid and / or amino acid derivative, it is possible to supplement the hair with the protein and amino acid that are easily lost during the decolorization treatment. Therefore, without lowering the decolorizing effect, not only the moistness and smoothness after decoloring can be maintained, but also the effect of suppressing the loss of firmness and stiffness due to protein elution can be obtained.

The decolorizing agent to be used in the present invention is not particularly limited, and various types of decolorizing agents are targeted, usually, a two-component type consisting of a combination of an alkali agent and an oxidizing agent, One-component type containing hydrogen peroxide, 3
There is also a multi-dose type that is more than a drug. However, a two-component type in which a second agent containing an alkaline agent, a protein hydrolyzate, and an amino acid derivative is mixed at the time of use is preferable in terms of product stability. The mixing ratio of the first agent and the second agent is usually the first by weight ratio.
Agent: Second agent = 1: 1 in many cases, but it is not particularly limited as long as there is no inconvenience in dripping, usability, decolorizing effect, feeling of use and the like. The oxidizing agent used in the present invention includes:
Examples thereof include hydrogen peroxide, persulfate, perborate, bromate, periodate, and urea peroxide.
