Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hair cosmetic containing loofah water that has the effect of inhibiting dandruff and itching.

(Conventional techniques and issues) Conventional methods for preventing dandruff include keratinization control,
Three methods are known: microbial control and sebaceous gland control, and many of the anti-dandruff agents currently on the market attempt to achieve their initial objectives by combining these methods. Sulfur, zinc pyrithione, selenium disulfide, etc. are mainly used as such anti-dandruff agents. However, these ingredients are sparingly soluble or insoluble in shampoo chemicals, and when such ingredients are used, they are subject to significant formulation restrictions in order to maintain dispersion stability, so they have the disadvantage that their shampoo performance is considerably inferior to that of general shampoos. there was. Therefore, anti-dandruff agents that are easily soluble in shampoos include triclosan, trichlorocarbanide, vilactone olamine, solubilized sulfur, and undecylenic acid. However, when such ingredients are added to shampoo agents, their anti-dandruff effect cannot be fully exerted because their antibacterial properties are significantly inhibited or their amount is limited due to coloring or clothing. On the other hand, cosmetics containing bactericides and antibacterial agents have safety issues due to their irritation to the skin, causing dandruff and itching, and their daily use can disrupt the delicate balance of the skin's resident bacteria. From an ecological perspective, it has been pointed out that in some cases, this may lead to unfavorable situations. From the above, it has been considered most desirable to suppress dandruff and itching with hair cosmetics that do not contain bactericidal or antibacterial agents. Until now, α-tocopherol has been used as a substance that is not based on antibacterial or bactericidal properties and also has dandruff and itch prevention effects.
Vitamin A ester (JP 51-73137), vitamin E nicotinic acid ester (German patent No. 2301)
No. 585, No. 2301660) α-tocopherol acetate and bantothenyl ethyl ether (Japanese Patent Application Laid-open No. 58-39611), α-tocopherol acetate and methionine (Japanese Patent Application Laid-open No. 59-7111), 1987-7112) Pantothenic acid and hydroquinone glycosides
210021), vitamin D, derivatives (JP-A-62-1
69717) and many others have been proposed.

However, these vitamins are unsatisfactory because some of them are undesirable in terms of skin irritation, and others have poor stability in formulations and on the skin, making it impossible to expect a sustained effect in suppressing dandruff. The desired dandruff-preventing effect has not yet been obtained. In addition, these have the disadvantage that they are generally expensive and that it may be difficult to incorporate them in large quantities in terms of formulation.

On the other hand, many proposals have been made to use plant extracts as dandruff and itch inhibitors that do not have the above-mentioned drawbacks. (JP-A-59-88412, JP-A-61-2387
17, JP-A-63-88113, JP-A-63-9611
7, JP-A No. 63-119413) However, these also have the disadvantage that they do not have sufficient dandruff and itch inhibiting effects, and are too expensive to be blended to the extent that they are sufficiently effective.

In view of the current situation, the present inventors have conducted extensive research in order to obtain a hair cosmetic that is highly safe for the skin, has good stability in the formulation or on the skin, and has the effect of suppressing dandruff and itching.

As a result, the inventors discovered that by incorporating loofah water, a hair cosmetic with high skin safety and good stability in the formulation or on the skin can be obtained, and the present invention has been completed.
