Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a hair cosmetic containing luffa water, which has an effect of controlling dandruff and Kayumi.

(Prior art and problems) As methods for preventing the occurrence of dandruff, three methods of keratinization control, microbial control and sebaceous gland control have been conventionally known, and most of the currently marketed anti-dandruff agents are as described above. Trying to achieve the intended purpose by combining different methods. As such anti-dandruff agents, sulfur, zinc pyrithione, selenium disulfide and the like are used. However, these are hardly soluble or insoluble in shampoo drugs, and when such components are dissolved, they are greatly restricted in the formulation in order to maintain dispersion stability. Was. For this reason, antidandruff agents that are easily dissolved in shampoos include triclosan, trichlorocarbanide, pyrocton auramine, solubilized sulfur, undecylenic acid, and the like. However, when such a component is added to a shampoo, the antibacterial property is significantly inhibited, or the amount of the component is limited due to coloring or odor, so that the effect of preventing dandruff cannot be sufficiently exerted. On the other hand, cosmetics containing disinfectants and antibacterial agents have a problem in safety from the aspect of skin irritation and cause dandruff and Kayumi, or break the delicate balance of bacteria indigenous to the skin due to daily use. From an ecological point of view, it has been pointed out that in some cases, this may cause undesirable situations.
From the above, it has been considered most preferable to prevent dandruff and Kayumi with a hair cosmetic containing no disinfectant or antibacterial agent. Until now, α-tocophenol / vitamin A ester (Japanese Patent Laid-Open No. 51-73137) has been used as a substance which is not based on antibacterial properties and bactericidal properties and has an effect of inhibiting dandruff and kayumi.
Vitamin E nicotinic acid ester (German Patent No. 230158
No. 5, No. 2301660) α-tocopherol acetate and pantothenyl ethyl ether (JP-A-58-3961)
1), α-tocopherol acetate and methionine (JP-A-59-7111), α-tripherol amino acid ester (JP-A-59-7112), pantothenic acid and hydroquinone glycoside (JP-A-61-210021), vitamins D ₃ derivatives has been proposed (JP 62-169717) and many.

However, some of these vitamins are not desirable in terms of skin irritation, and some of them have poor stability in the preparation and on the skin, and do not have the expected effect of suppressing dandruff. The obtained dandruff deterrent effect has not yet been obtained. In addition, they are generally expensive and have the drawback that it may be difficult to mix them in large amounts even in pharmaceutical preparations.

On the other hand, many proposals have been made to use a plant extract as a dandruff and Kayumi inhibitor that does not have the above-mentioned disadvantages. (Japanese Unexamined Patent Publication Nos. 59-88412, 61-238717, 6
However, these also have the drawback that they are not sufficiently effective in suppressing dandruff and Kayumi and cannot be blended to obtain a sufficiently high price because they are expensive. I was

In view of this situation, the present inventor has conducted studies to obtain a hair cosmetic composition having high skin safety and having an excellent effect of inhibiting dandruff and Kayumi in the preparation or on the skin. As a result, it has been found that a hair cosmetic with high skin safety and good stability in a preparation or on the skin can be obtained by adding luffa water, and the present invention has been completed.
