Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a cosmetic for hair.
More specifically, the present invention relates to a cosmetic for hair having a hot feeling in which polyoxyethylene polyoxypropylene glyceryl ether is an essential component and, if necessary, a polyhydric alcohol is added.

[0002]

2. Description of the Related Art Generally, hair care products of hair cosmetics have a moisture component, an emollient component, a treatment component, etc. which penetrates into and is absorbed in the hair to prevent or improve damage to split ends and the like, and makes the hair easy to handle. It is used to keep you healthy. In addition, scalp care products include dandruff prevention products, hair-growth agents, hair-growth agents, etc., which are used for the purpose of sufficiently permeating and absorbing active ingredients into the scalp, suppressing dandruff, promoting hair-growth and hair-growth. ing.

By the way, as a method for enhancing the effects of these hair care products and scalp care products, conventionally, some beauty technical methods such as wearing a hair cap, steaming with a steam towel, and massaging the scalp have been performed. But,
All of them have a drawback that they are troublesome and not convenient.

On the other hand, for the skin, as a product having an effect of enhancing the effect of a skin care product, generally, a massage cream having effects of promoting blood circulation of the skin, imparting flexibility to the skin, moisturizing, promoting blood circulation, cleansing, etc. Packs and the like having effects such as are widely used.

Recently, a skin gel composition described in JP-A-2-311408 and JP-A-4-89424 have been disclosed.
Like the exothermic aerosol composition described in Japanese Patent Laid-Open Publication No. JP-A No. 2004-242242, a cosmetic composition is blended with a component that reacts with moisture on the skin or moisture in the air to generate heat of hydration, and its thermal action causes massage or Attempts have been made to achieve effects similar to those obtained with the pack.

[0006] However, there is no hair cosmetic that has the function of enhancing the effects of hair care products and scalp care products by the action of heat and the like, and even if the above skin products are used for hair, Since massage cream contains a large amount of liquid oily ingredients, it is difficult to remove it from the scalp and hair after use. Japanese Patent Laid-Open No. 2-3114
Since the cosmetic of JP-A No. 08 is in the form of gel, it cannot be applied quickly and evenly to the hair and scalp, and a sufficient heating effect cannot be obtained. Further, in the cosmetic of JP-A-4-89424,
Since zeolite of inorganic powder is an essential component, it may damage the scalp and hair by rubbing when applied to the scalp and hair, and since it uses a propellant, it feels cold at the moment of application due to heat of vaporization There are too many problems to use it as a cosmetic for hair, for example.

Therefore, there has been a demand for the development of a simple cosmetic for hair which also has a heating effect.

[0008]

SUMMARY OF THE INVENTION The present invention has been made from the above point of view and has a function of enhancing the effect of hair cosmetics such as hair care products and scalp care products by having a heating effect and is simple and easy. An object is to provide a cosmetic for hair that can be used for.

[0009]

Means for Solving the Problems As a result of intensive research to solve the above problems, the present inventor has found that polyoxyethylene polyoxypropylene glyceryl ether is an essential ingredient and, if necessary, polyhydric alcohol is used as hair. The scalp and hair can be quickly covered by blending it with a specific ratio in cosmetics for hair, and the thermal action of the reaction hydration heat with the moisture in the scalp and hair causes the thermal effect of hydration to produce hair cosmetics such as hair care products and scalp care products. They have found that the effect can be enhanced, and have completed the present invention.

That is, according to the present invention, one or more polyoxyethylene polyoxypropylene glyceryl ethers represented by Chemical Formula 2 are contained in an amount of 30% by weight or more based on the total amount of the cosmetic, and water is used in an amount of 30% based on the total amount of the cosmetic. A cosmetic for hair having a hot feeling characterized by being blended in an amount of less than or equal to% by weight (hereinafter,
This is referred to as the hair cosmetic composition of the present invention).

Comparative hair treatments were prepared in which the total amount of polyhydric alcohols up to 600 was below the blending range of the invention.

[0034]

[Table 2]

<Evaluation> The hair treatment of each of the examples and comparative examples obtained above was subjected to an actual use test,
The blended polyoxyethylene polyoxypropylene glyceryl ether or polyoxyethylene polyoxypropylene glyceryl ether has a molecular weight of 50 to 60.
Along with 0 polyhydric alcohol, it was evaluated whether the effectiveness of the treatment ingredients was enhanced.

Each sample was assigned to 5 groups of 5 female panelists, 1 group each, and they were continuously used for 1 week, and sensory evaluation of the treatment effect was carried out. Similar to the usual hair treatment, the sample was used after shampooing, thoroughly removing water from the hair, applying the sample evenly to the hair, leaving it for 3 minutes, and then rinsing with warm water. In addition, the evaluation of the treatment effect was carried out by a method in which, as the treatment actual feeling at the end of the test, gloss, combability (smoothness), and dryness were reported.

The results of the above test are shown in the bottom column of Table 2. As is clear from this result, the molecular weight of polyoxyethylene polyoxypropylene glyceryl ether was 50
