Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to various components for hair, such as hair dyes, conditioning polymers, fragrances, softening agents, beam / strain imparting agents, perm effect enhancers, and damage reducing agents. The present invention relates to a hair treatment composition having an improved penetration rate or penetration amount. In particular, it relates to a hair treatment composition for hair dye containing a hair dye.

[0002]

2. Description of the Related Art Hair treatment compositions for hair dyeing, perming or damage care have been known. Most of these hair treatment compositions infiltrate the hair with specific ingredients in order to achieve their purpose.

For example, in the case of a hair treatment composition for hair dyeing, an acid dye which has relatively little effect on the scalp and hair and which can be dyed easily is blended and allowed to penetrate into the hair. Have dyed hair. In this case, since the acid dye alone is insufficient in permeation rate and permeation amount into hair, benzyl alcohol is blended as a permeation enhancer in the hair treatment composition for hair dyeing.

Further, also in a hair treatment composition for performing a permanent treatment, a permanent hair setting, etc., it is necessary to infiltrate a keratin reducing agent for cleaving a disulfide bond of keratin into the hair. Benzyl alcohol is blended as a penetration enhancer. Similarly, also in the case of a hair treatment composition containing a hair / strain imparting agent, a hair softening agent, a hair damage reducing agent, etc., benzyl alcohol is blended as a penetration enhancer.

[0005]

However, when benzyl alcohol is used as a penetration enhancer, if the concentration of the dye for hair dyeing and the hair treatment time are set within the range of good handleability, hair for hair dyeing There is a problem that the hair dyeing properties of the treatment agent composition become insufficient.

Also, in other hair treatment compositions,
Similarly, there is a problem that the penetration promoting effect is insufficient.

The present invention is intended to solve the problems of the conventional techniques as described above, and a hair treatment composition having a compound having a penetration promoting action superior to that of the conventional penetration promoting agent benzyl alcohol. The purpose is to provide.

[0008]

The present inventor has found that the above-mentioned object can be achieved by using a specific aromatic group-containing alcohol having a penetration promoting action in a specific blending amount, and the present invention has been completed. Came to let.

[0009]

That is, the present invention is a 2-phenoxy-2-me
Cylethanol or 2-benzyloxy-1,3-pro
Providing a propanediol hair treatment composition in a proportion of 0.1 to 30 wt%.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below.

In the hair treatment composition of the present invention, a specific aromatic group-containing alcohol having a penetration promoting action ,
That is, 2-phenoxy-2-methylethanol or 2
-Use benzyloxy-1,3-propanediol . These specific aromatic group-containing alcohols are capable of accelerating the permeation rate of various hair treatment components into the hair and increasing the permeation amount as compared with the conventional permeation enhancer benzyl alcohol.

[0013]

In the present invention, 2-
Phenoxy-2-methylethanol or 2-benzyloxy-1,3-propanediol is used, but 2-phenoxy-2-methylethanol is used because of its weak odor.
Can be preferably used.

The blending amount of the above-mentioned specific aromatic group-containing alcohol in the hair treatment composition is 0.1 to 30% by weight, preferably 1 to 15% by weight. 0.1% by weight
If it is less than the above range, a sufficient penetration promoting effect cannot be obtained, and if it exceeds 30% by weight, the solubility in water is lowered and a uniform composition cannot be obtained, and further improvement of the penetration promoting effect cannot be expected.

In the hair treatment composition of the present invention, in addition to the above-mentioned specific aromatic group-containing alcohol, various hair treatment components are blended depending on the purpose of use. In that case, as described above, the permeation rate and permeation amount of these hair treatment components into the hair are enhanced.

For example, a hair dye may be added to the hair treatment composition as a hair treatment component. Thereby, the hair can be sufficiently dyed. Here, as the hair dye, various dyes known as hair dyes can be used, but as compared with other dyes, the specific dye described above is used.
It is preferable to use an acid dye having a high effect of promoting permeation into hair by the aromatic group-containing alcohol .

Examples of such acid dyes include nitro dyes, azo dyes, nitroso dyes, triphenylmethane dyes, xanthene dyes, quinoline dyes, anthraquinone dyes and indigo dyes. Specifically, red 2, red 3, red 102, red 104

If the amount of these acid dyes to be added to the hair treatment composition is too small, the dyeability is insufficient, and if it is too large, the solubility is lowered and further improvement in dyeability cannot be expected. The amount is 0.0001 to 10% by weight, more preferably 0.01 to 1% by weight. In this case, it is preferable that the hair treatment composition for hair dye has a water content of 10 to 97% by weight.

If the pH of the hair treatment composition containing such an acid dye as a dye for dyeing is too low, the hair or scalp may be damaged, and if it is too high, the dyeability is deteriorated. It is adjusted to 2 to 6, more preferably 2 to 4. In this case, the pH can be adjusted by appropriately adding an organic acid such as lactic acid, tartaric acid, acetic acid, citric acid and oxalic acid, or an inorganic acid such as phosphoric acid and hydrochloric acid to the hair treatment composition.

A keratin reducing agent may be added to the hair treatment composition as a hair treatment component. This makes it possible to sufficiently cleave the disulfide bond of keratin that composes hair. Such a hair treatment composition can be preferably used as a permanent wave first agent.

In this case, the keratin reducing agent is preferably thioglycolic acid and its derivative, thiolactic acid and its derivative, cysteine and its derivative or their salts, thioglyceryl alkyl ether of the formula (2) or its salt.

If the amount of these keratin reducing agents blended in the hair treatment composition is too small, the reduction of keratin will be insufficient, and even if added excessively, the effect commensurate with the amount added cannot be obtained. It is preferably 0.1 to 20% by weight, more preferably 1 to 5% by weight. In this case, the pH of the hair treatment composition is preferably 3.0 to 9.5, and more preferably 4.0 to 9.5 in order to suppress damage to the skin and hair.
