DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treating agent containing an oxidizing agent used for a depigmenting agent for hair or a hair coloring agent.

[0002]

2. Description of the Related Art Hair treatment agents containing an oxidizing agent include a bleaching agent for hair, a second agent for oxidative hair dyes, a second agent for permanent waves, and the like. These aqueous forms, when applied to the hair, have the drip and may be attached to the skin or clothes when applied to the hair. Emulsions also have a problem that the amount of surfactant is large and skin irritation is likely to occur. In addition, there is a problem that the gel-like material is susceptible to oxidative decomposition by an oxidizing agent and has very poor viscosity stability. In order to solve these problems, Japanese Patent Publication No. 58806/1988 proposes the use of xanthan gum, but has the drawback that it has no oxidation inhibiting effect and damages hair.

[0003]

Therefore, there has been a demand for an oxidizing agent-containing hair cosmetic which has no dripping, has little skin irritation, has good viscosity stability, and has little hair damage.

[0004]

[Problems to Solve the Problems] The present inventors have proposed an oxidizing agent and
In hair cosmetics containing water and water, by containing a cellulose derivative and a specific antioxidant, there is no dripping, less skin irritation, good viscosity stability,
It has been found that hair damage is reduced.

The oxidizing agent used in the present invention includes hydrogen peroxide, bromate, iodate, periodate and other hydrogen peroxide adducts. Among them, hydrogen peroxide and bromate Bromates such as sodium and potassium bromate are preferred. The compounding amount is 1 to 9% by weight. If less than 1% by weight, a sufficient oxidation effect cannot be obtained, and 9% by weight
Beyond, there is a risk of hair damage.

The cellulose derivatives used in the present invention include hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, methyl cellulose, carboxymethyl cellulose, sodium carboxymethyl cellulose, hydroxyethyl cellulose hydroxypropyl trimethyl ammonium chloride ether, hydroxyethyl cellulose dimethyl diallyl ammonium chloride and the like. Can be Among these, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, methylcellulose, hydroxyethylcellulose hydroxypropyltrimethylammonium chloride ether and hydroxyethylcellulose dimethyldiallylammonium chloride are more effective in preventing dripping, and are effective in inhibiting skin irritation and hair damage. It is particularly preferable because effects can be obtained. The compounding amount is from 0.01 to 10% by weight. If the amount is less than 0.01% by weight, a sufficient dripping preventing effect and an effect of inhibiting skin irritation and hair damage cannot be obtained, so that 10% by weight is not obtained. If it exceeds, the viscosity may increase with time. The lower limit of the amount is 0.1% by weight.
It is preferable to add 0.1% by weight or more, whereby a more excellent dripping prevention effect, skin irritation and hair damage suppression effects can be obtained. The upper limit is preferably 5% by weight, and when it exceeds 5% by weight, the feeling of application becomes slightly heavy, and the increase in skin irritation and the effect of suppressing hair damage is reduced.

The antioxidants used in the present invention include butylhydroxyanisole, dibutylhydroxytoluene, propyl gallate, octyl gallate, dl-α-
At least one selected from tocopherol, d-δ-tocopherol, tocopherol acetate and natural vitamin E
Seeds, excellent viscosity stability, and skin irritation and hair damage suppressing effects are obtained . The amount of its 0.0
When the amount is less than 0.001% by weight, sufficient viscosity stability, skin irritation and the effect of suppressing hair damage cannot be obtained, and even when the amount exceeds 10% by weight, the effect is further improved. Is not economical because it is not available. The lower limit of the amount is 0.01% by weight or more, whereby more excellent viscosity stability, skin irritation and an effect of suppressing hair damage are obtained. 5% by weight for upper limit
When it exceeds 5% by weight, the increase in viscosity stability, skin irritation and the effect of suppressing hair damage are reduced.

[0008] Further, by incorporating an ultraviolet inhibitor into the hair treatment composition of the present invention, more excellent viscosity stability can be obtained. Examples of UV inhibitors include urocanic acid, ethyl urocanate, oxybenzone, oxybenzonesulfonic acid, ethylene glycol salicylate, octyl salicylate, dipropylene glycol salicylate, phenyl salicylate, homomenthyl salicylate, methyl diisopropylcinnamate, sinoxate, diparamethoxycinnamate Glyceryl mono-2-ethylhexanoate, dihydroxydimethoxybenzophenone, sodium dihydroxydimethoxybenzophenone disulfonate, dihydroxybenzophenone, tetrahydroxybenzophenone, paraaminobenzoic acid, ethyl paraaminobenzoate, 2-ethylhexyl paradimethylaminobenzoate, paradimethylaminobenzoate Amyl acid, octyl paradimethylaminobenzoate, paramethoxysilicic acid Acid isopropyl diisopropyl cinnamate ester mixture, para-methoxy cinnamate 2
-Ethylhexyl, 2- (2-hydroxy-5-methylphenyl) benzotriazole, sodium hydroxymethoxybenzophenonesulfonate, 4-tert-butyl-4'-methoxybenzoylmethane, octyl methoxycinnamate and the like. The compounding amount is 0.00
If the amount is less than 0.001% by weight, the improvement in viscosity stability is small, and if it exceeds 5% by weight, no further effect is obtained, so that it is not economical.

Further, by blending at least one selected from phenacetin, 8-oxyquinoline and urea with the hair treatment composition of the present invention, more excellent viscosity stability, skin irritation and hair damage are obtained. Is preferable because the effect of suppressing the above can be obtained. The compounding amount is 0.001 to 5% by weight. If the amount is less than 0.001% by weight, sufficient viscosity stability, skin irritation and the effect of suppressing hair damage cannot be obtained, and the amount exceeds 5% by weight. However, it is not economical because no further effect can be obtained. The lower limit of the compounding amount is preferably 0.005% by weight. By adding 0.005% by weight or more, more excellent viscosity stability, skin irritation, and an effect of suppressing damage to hair can be obtained. The upper limit is preferably 3% by weight, and when it exceeds 3% by weight,
The increase in viscosity stability, skin irritation and the effect of suppressing hair damage is reduced.

The hair treatment composition of the present invention is used as a decolorizing agent for hair, a second agent for oxidative hair dye, an acidic hair dye, a second agent for permanent wave, a setting agent for hair, and the like. The dosage form is a liquid, cream, paste, or gel and has a transparent or translucent beautiful appearance and high commercial value.

In addition, the hair treatment composition of the present invention includes surfactants, solvents such as ethanol, benzyl alcohol, and pyrrolidone, organic acids, inorganic acids, oils, silicones, humectants,
A setting agent, a resin, a dye, a pigment, a fragrance, an ultraviolet absorber, and the like can be appropriately compounded.
