Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing agent for scalp and hair such as shampoo. More specifically, it has a high level of safety and stability while having cleansing power, and also has a refreshing feel during and after use, and also has a smooth feel, and is a quick-drying wipe type scalp and hair. Regarding cleaning agents.

[0002]

2. Description of the Related Art Cleaning agents for scalp and hair such as shampoo generally require rinsing with water or hot water after washing the scalp and hair with 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. For this reason, a wiping-type cleaning material that does not require rinsing has been devised.

For example, an aerosol type aqueous detergent composition (Japanese Patent Publication No. 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.

However, the above conventional techniques have the following problems.
That is, in the technique using the electrolyte-based surfactant, the scalp and the hair were not sufficiently satisfactorily just wiped off. In addition, in the technique of using organic solvents such as acetone and ether, the safety to the scalp and hair,
It was not at a satisfactory level in terms of irritation and the feel after use was not smooth. Further, the water-based base is still unsatisfactory because of insufficient cleaning effect and refreshing feeling.

Therefore, the object of the present invention is to have a high safety and stability while having a detergency, an excellent refreshing feeling during and after use, a smooth feeling after use, and a quick drying property. It is intended to provide a cleansing agent for scalp and hair of a wiping type.

[0006]

Means for Solving the Problems As a result of intensive studies in view of such circumstances, the present inventors have found that a lower monohydric alcohol and water are used, and a fluorine-containing surfactant and an organic acid or an organic acid are used. By using a specific amount of the acid salt in combination, it is possible to improve the drawbacks of the prior art as described above, while having a detergency,
The present invention has been completed by discovering that a cleansing agent for scalp and hair that has high safety and stability, has a smooth and refreshing feel, and is quick-drying can be obtained.

That is, the present invention provides one or more lower monohydric alcohols having 1 to 3 carbon atoms in an amount of 30 to 7
0% by weight, 30 to 70% by weight of water, 0.1 to 10% by weight of one or more kinds of fluorine-containing surfactants, and one or more kinds selected from organic acids or organic acid salts. The present invention provides a cleansing agent for scalp and hair, which comprises:

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 are 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 insufficient. On the other hand, when it exceeds 70% by weight, precipitation of organic acid or organic acid salt is observed and the stability becomes poor, which is not preferable.

The fluorine-containing surfactant used in the present invention is Pf-CH ₂ CH ₂ O- (CH ₂ CH ₂ O).
₂ H, Rf-CH ₂ CH ₂ CONH- (CH ₂ CH ₂ O) ₂ H, Rf
_{-CH 2 CH 2 S- (CH 2} CH 2 O) 2 H, a surfactant general structure etc. like. Specifically, Zonyl FSN
(E.I.Dupont Demonace and Company) and the like.

The amount of the fluorine-containing surfactant used in the present invention is 0.1 to 1 in the cleaning agent for scalp and hair.
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 cannot be obtained, and it is sticky and the feeling of use is deteriorated, which is not preferable. It is preferably used in the range of 0.1 to 5% by weight for refreshing the feel after use.

The organic acid or organic acid salt used in the present invention is aspartic acid, alginic acid, edetic acid, citric acid, glycyrrhizinic acid, glycyrrhetinic acid, gluconic acid, glutamic acid, succinic acid, salicylic acid, tartaric acid,
Sorbic acid, lactic acid, pyruvic acid, pyrrolidone carboxylic acid, malic acid, or Na, K, Ca, Mg of these
Examples thereof include ammonium salts.

The scalp and hair cleansing agent of the present invention comprises, in addition to the above-mentioned components, a polyhydric alcohol, a polysaccharide, a protein derivative, in a quantitative and qualitative range that does not impair the effects of the present invention, depending on the purpose. You may add a chemical | medical agent, an antioxidant, a fragrance | flavor, etc.

As the polyhydric alcohol, 1,2-propanediol, 1,3-propanediol, 1,2-butanediol, 1,3-butanediol, 1,4-butanediol, dipropylene glycol, glycerin, Diglycerin, sorbitan, sorbitol, maltitol,
Glucose, sucrose and the like can be mentioned.

Examples of polysaccharides include hyaluronic acid, chondroitin sulfate, dermatanic acid, keratan sulfate, heparan sulfate and salts thereof.

As drugs, vitamin Cs and vitamin E
It is possible to add agents commonly used in cosmetics, such as compounds, amino acids, crude drugs, anti-inflammatory agents, and bactericides.

Further, the scalp and hair cleansing agent of the present invention comprises
It is generally used by applying it directly to the head, but the application method is the type of applying directly from the container,
It may be either a mist type or a bubble type. Also, when spraying in mist or foam,
It may be either a natural pressure spray, a compressed gas, or an aerosol type using a liquefied gas.
