Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scalp and hair cleaning agent such as shampoo. More specifically, the present invention relates to a wipe-type scalp and hair cleaning agent that does not need to be washed off with water and can be cleaned by simply wiping with a towel or the like.

[0002]

2. Description of the Related Art A cleansing agent for scalp and hair such as shampoo generally needs to be rinsed with water or hot water after washing the scalp and hair using the same. Therefore, it is not easy to wash the scalp and hair with such a general scalp and hair cleaner when it is not possible to take a bath due to illness or injury or where water cannot be easily used. Was difficult to clean. Therefore, a wiping-type cleaning material that does not require rinsing has been devised.

For example, an aerosol type aqueous detergent composition (JP-B-57-47960), a foamy hair wash (JP-A-61-289023), a composition for wiping shampoo (JP-A-62-205011), A dry hair washing method and an agent therefor (JP-A-63-14711), an aerosol shampoo composition (JP-A-63-190813) and the like are disclosed.

[0004]

However, the conventional scalp and hair cleaning agents of the prior art as described above have the following problems. That is, in the technology using the electrolyte-based surfactant, there is a problem in stimulating the scalp and hair just by wiping it off, and in this respect, the level is not sufficient.
There was also a problem with low temperature stability. Further, the technique using an organic solvent such as acetone or ether is not at a satisfactory level in terms of safety and irritation to the scalp and hair. Further, in the technique using a foam-like dosage form, the amount of alcohol blended is limited to a low level due to the formation of foam, and the cleaning effect and refreshing feeling are insufficient, and it is difficult to effectively reach the scalp with the active ingredient. For some reason, I was still not satisfied.

Therefore, the object of the present invention is to effectively reach the active ingredient not only to the hair but also to the scalp, and to provide a refreshing feeling during and after use, and to ensure safety and low temperature stability. It is intended to provide a high-wiping type scalp and hair cleaning agent.

[0006]

Means for Solving the Problems As a result of intensive studies in view of the above circumstances, the present inventors have used a lower monohydric alcohol and water, and further added a non-electrolyte type surfactant ,
By using a specific amount of a specific organic acid or an organic acid salt in combination, it is possible to improve the above-mentioned drawbacks of the prior art, and it is possible to obtain a scalp and hair cleansing agent with a refreshing feeling of use. Heading out, the present invention has been completed.

That is, according to the present invention, ethanol is added to 30 to 30%.

The present invention provides a scalp and hair cleansing agent (excluding aerosol-type foamy hair washes) which is clothed or sprayed in a mist form .

The structure of the present invention will be described in detail below. Examples of the lower monohydric alcohol having 1 to 3 carbon atoms used in the present invention include methanol, ethanol and n.
-Propanol and i-propanol may be mentioned, but ethanol modified with brucine or the like is preferable from the viewpoint of toxicity and the like.

The amount of the lower monohydric alcohol used in the present invention is 30 to 70% by weight in the scalp and hair cleaning agent. If it is less than 30% by weight, the refreshing feeling (cooling feeling) during use and after use is insufficient, and
The cleaning effect for stains on the scalp and hair is also insufficient. On the other hand, if the amount exceeds 70% by weight, precipitation of organic acid or organic acid salt is observed and the safety becomes poor, which is not preferable.

As the non-electrolyte type surfactant used in the present invention, sorbitan fatty acid ester, polyoxyethylene (hereinafter abbreviated as "POE") sorbitan fatty acid ester, POE alkyl ether, POE alkylaryl ether, glycerin fatty acid ester, POE
Examples thereof include glycerin fatty acid ester, polyglycerin fatty acid ester, POE polyglycerin fatty acid ester, alkyl glyceryl ether, POE alkyl glyceryl ether, alkyl glucoside, and POE alkyl glucoside. Of these, POE alkyl ethers and POs are especially preferred from the viewpoints of safety, detergency and low temperature stability.
E sorbitan fatty acid esters are preferred.

The amount of the non-electrolyte surfactant used in the present invention is 0.1 to 1 in the scalp and hair cleaning agent.
It is 0% by weight. If it is less than 0.1% by weight, the detergency is insufficient, and if it exceeds 10% by weight, a refreshing feeling during use and after use is not obtained, and the feeling of use is deteriorated, which is not preferable.

[0012] organic acid or organic acid salt used in the present invention, glycyrrhetinic acid, citric acid, malic acid, Pi Le <br/> bottles acid, salicylic acid or their Na,, K, Ca,
Examples thereof include Mg and ammonium salts.

The cleansing agent for scalp and hair of the present invention comprises, in addition to the above-mentioned components, polyhydric alcohols, polysaccharides, and protein derivatives in quantitative and qualitative ranges that do not impair the effects of the present invention, depending on the purpose. , Chemicals, antioxidants, fragrances and the like may be added.
