Abstract

PURPOSE:To obtain a hair-treating agent containing an oxidizing agent by adding a cellulosic derivative and an antioxidant, thus the agent causes no sagging, exerts reduced skin irritation and reveals high stability in viscosity and reduced damage of hair. CONSTITUTION:To a hair-treating agent containing an oxidizing agent which is useful as a decoloring agent for hair or a hair dye, are added a cellulosic derivative (in an amount of 0.01-10wt.%) and an antioxidant (in an amount of more than 0.01wt.%). Hydroxyethyl cellulose, hydroxypropyl methyl cellulose, methy cellulose or the like is particularly preferably used as a cellulosic derivative because they develop the excellent inhibition of sagging and exert the effect of suppressing the skin stimulation and hair damage. The antioxidant is particularly preferably butylhydroxyanisole dibutyl-hydroxytoluene, propyl gallate, octyl gallate, dl-alpha-tocopherol, vitamin E or the like because they manifest excellent effects of stabilizing viscosity and inhibiting skin irritation and hair damage.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment agent containing an oxidizing agent used for decolorizing agents for hair, hair dyes and the like.

[0002]

2. Description of the Related Art As a hair treatment agent containing an oxidizing agent, there are a depigmenting agent for hair, a second agent for oxidative hair dye, a second agent for permanent wave, and the like. When these aqueous solutions were applied to the hair as these dosage forms, there was a risk of dripping and sticking to the skin or clothes. Further, the emulsion has a problem that it contains a large amount of the surfactant and is likely to cause skin irritation. In addition, gels have a problem that they are susceptible to oxidative decomposition by an oxidizing agent and have very poor viscosity stability. In order to solve these problems, Japanese Patent Publication No. Sho 63-58806 proposes to use xanthan gum, but it has a drawback that it has no effect of suppressing oxidation and damages hair.

[0003]

Therefore, there has been a demand for a hair cosmetic containing an oxidizing agent, which is free from dripping, has less skin irritation, has good viscosity stability, and has less hair damage.

[0004]

Means for Solving the Problems In the hair cosmetics containing an oxidant, the present inventors have formulated a cellulose derivative and an antioxidant to prevent dripping, less skin irritation, and viscosity stability. It was found to be good, with less damage to the hair.

It is 1 to 5% by weight, and if it is less than 0.001% by weight, the improvement of the viscosity stability is small, and if it exceeds 5% by weight, no further effect can be obtained, which is not economical.

Further, by incorporating at least one selected from phenacetin, 8-oxyquinoline and urea into the hair treatment composition of the present invention, more excellent viscosity stability and skin irritation and damage to hair are obtained. It is preferable because the effect of suppressing is obtained. The blending amount is 0.001 to 5% by weight, and if it is less than 0.001% by weight, sufficient viscosity stability and effects of suppressing skin irritation and hair damage cannot be obtained, and it exceeds 5% by weight. However, it is not economical because it does not produce any further effect. The lower limit of the blending amount is preferably 0.005% by weight, and by blending 0.005% by weight or more, more excellent viscosity stability and effects of suppressing skin irritation and hair damage can be obtained. Regarding the upper limit, 3% by weight is preferable, and when 3% by weight is exceeded,
Less increase in viscosity stability, and skin irritation and suppression of damage to hair.
