It is adjusted so that the content is not more than wt%.

The water is a component used to form the obtained hair styling composition in the form of foam on the coated surface.

The water is not particularly limited, and purified water such as distilled water and ion-exchanged water which are usually used in hair styling compositions can be used.

The amount of water used should be 98% by weight or less, preferably 95% by weight or less in the stock solution so that the hair styling composition can have a sufficient setting force. In order to make the adjusted and obtained hair styling composition have a form on the coated surface, it is adjusted to be contained in the stock solution in an amount of 25% by weight or more, preferably 45% by weight or more.

The stock solution used in the present invention is a hair styling base,
It is obtained by mixing the monohydric lower alcohol and water in the predetermined amounts described above.

In the present invention, if necessary, various additives such as ultraviolet absorbers, fragrances, moisturizers such as propylene glycol, preservatives, stabilizers, etc. may be added within the range not impairing the object of the present invention. It may be added to the stock solution. Usually, the amount of such additives used is 0.00
It is adjusted to contain 5 to 10% by weight.

Next, the hair styling composition of the present invention is obtained by mixing the stock solution with a propellant.

Examples of the propellant include liquefied petroleum gas (main component: propane, isobutane and normal butane), difluoromonochloroethane, monofluorodifluoromethane, hydrofluorocarbons such as tetrafluoroethane, liquefied gas such as dimethyl ether;
Compressed gases such as N ₂ , N ₂ O, CO ₂ and air can be used. These may be used alone or in combination of two or more.

In the present invention, in order to impart sufficient foaming properties to the obtained hair styling composition, liquefied petroleum gas is contained as a propellant in an amount of 70 to 100% by weight (liquefied petroleum gas alone). Is used. Further, the pressure of the hair styling composition containing the propellant at 35 ° C. is 2 kg · G / cm ² so that the obtained hair styling composition is sufficiently and favorably jetted. Above, 4k
g / G / cm ² or more is preferable, and from the viewpoint of safety, 8 kg · G / cm ² or less, especially 7 kg ·
It is preferably G / cm ² or less.

Weight ratio of stock solution and propellant (stock solution / propellant)
Is 3/97 or more, preferably 5/95 or more, in order to foam the mist-shaped hair styling composition on the coated surface, and 45 // in order to suppress over-foaming on the coated surface.
It is 55 or less, preferably 35/65 or less.

Thus, the hair styling composition of the present invention can be obtained by mixing the stock solution and the propellant.

If necessary, a part of the hair styling composition of the present invention may be replaced with a foaming regulator.

Typical examples of the foaming regulator include normanpentane and isopentane.
These foaming regulators can be used alone or in admixture of two or more.

The amount of the foaming regulator is 1% by weight or more, especially 3% by weight in the hair styling composition in order to obtain the effect exhibited by using the foaming regulator, that is, an appropriate foaming state. It is preferable to adjust the content to the above, and in order to prevent over-foaming on the coated surface, 30% by weight or less, especially 20
It is preferable to adjust the content to be less than or equal to wt%.

The hair styling composition of the present invention is used as a propellant.
Since liquefied petroleum gas is contained in an amount of 70% by weight or more, it is uncomfortable due to the dimethyl ether like a hair styling composition using a propellant containing dimethyl ether as a main component. No odor is emitted, and no corrosion is generated as in the case of using a metal aerosol container as the aerosol container.

Further, since the hair styling composition of the present invention is composed of the stock solution of the specific composition and the propellant as described above, it forms a mist at the time of spraying and foams after being adhered to the application surface, and the foaming thereof. After that, it quickly defoams and becomes liquid,
It reaches the hair near the scalp well, and makes styling easier.

The hair styling composition of the present invention is preferably adjusted so as to quickly defoam after foaming in order to quickly reach the hair near the scalp. In particular, it is preferable that it is adjusted so that the foam disappears within 0.5 to 150 seconds after foaming.

The hair styling composition of the present invention can be made into an aerosol product, for example, by filling a pressure resistant container for aerosol by a conventional method and attaching an aerosol valve and a button.

The pressure resistant container for aerosol is not particularly limited, and a commonly used container can be used.

In the present invention, when a liquefied gas is used as the propellant, it is preferable to use an aerosol valve having a shape as shown in FIG. 1, for example.

FIG. 1 is a schematic sectional view of an aerosol valve provided with a dip tube 1.

In FIG. 1, the ratio of the bore area of the hole 2 of the vapor tap to the bore area of the hole 3 of the under tap (the bore area of the hole 2 of the vapor tap / the bore area of the hole 3 of the under tap) is the pressure resistance for aerosol. In order to prevent only the propellant from remaining after the composition for hairdressing is sprayed from the container, it is preferably 0.05 / 1 or more, more preferably 0.06 / 1 or more, and a pressure resistant container for aerosol. In order to prevent only the undiluted solution from remaining after spraying the hair styling composition from above, it is preferably 2.0 / 1 or less, especially 1.8 / 1 or less.

Further, in the present invention, when the compressed gas is used as the propellant, the compressed gas hardly dissolves in the undiluted solution, and the compressed gas is prevented from being ejected before the undiluted solution. Therefore, it is preferable that the hole 2 of the vapor tap is not provided.
