The water-soluble polymer is in the range of 0.1 to 0.6% by weight, the powder is in the range of 12 to 25% by weight, and the alcohol is 32.1 to 76.4% by weight, assuming that the whole stock solution is 100% by weight. %, And purified water in the range of 4 to 10% by weight.

When the amount of each component in the undiluted solution is within the above range, the spray composition sprayed on the palm stretches well when stretched on the face, has a high exhilarating feeling at the time of use, and further has an electric razor. A spray composition that facilitates shaving is obtained.

In particular, if the amount of the water-soluble polymer in the stock solution is within the above range, the spray composition sprayed onto the palm from a spray can will stretch well when spread on the face. Further, when the compounding amount of the powder is within the above range, when the spray composition sprayed from the spray can is applied to the skin, there is no discomfort such as roughness, and further, the beard is erected. The effect is obtained. Since the spray composition in which the amount of alcohol is within the above range gives a strong astringent action and a bactericidal action to the user's skin, it is possible to prevent fine trauma formed on the skin during shaving from becoming purulent. Can be.
Furthermore, since the skin astringent action of alcohol and the effect of raising the whiskers by the powder are combined, the whiskers are in the erected state. Can be easily shaved. If the blended amount of purified water is within the above range, the spray composition sprayed on the palm does not dry before stretching on the face, and dries in a short time while stretching on the face, and immediately shaves. It is preferable because it can be made. Further, it is preferable in that the powder in the spray composition is not scattered when the spray composition is sprayed on the palm.

2. Propellant The propellant has a function of applying a spray pressure to the stock solution.
Any propellant can be used as long as it is a propellant used for ordinary spraying.However, dimethyl ether is used because it has a high solubility in alcohol and is well dissolved in the stock solution, and there is no possibility of destroying the ozone layer. preferable.

A liquefied petroleum gas or the like can be added to the dimethyl ether as required. However, the blending amount of the liquefied petroleum gas is preferably 37.5 parts by weight or less based on 100 parts by weight of the entire propellant. The dimethyl ether may further contain carbon dioxide gas or the like.

Other examples of the propellant include carbon dioxide, compressed air, chlorofluorocarbons, and butane.

The mixing ratio of the propellant and the stock solution is preferably in the range of stock solution / propellant = 36/64 to 60/40 (weight ratio). The spray composition in which the mixing ratio of the propellant and the stock solution is within the above range can provide a sufficient spray pressure when filled in a spray can, and the amount of the propellant is based on the amount of the stock solution. Since there is no too much, the inner volume of the spray can can be used effectively.
