Description

The present invention relates to an aerosol-type foamy hair cosmetic composition, and more particularly to an aerosol-type foamy hair cosmetic composition containing carbon dioxide as a propellant.

In recent years, attention has been focused on "carbonic acid" in the beauty industry as a whole. Although it was a service provided by the salon industry, with the introduction of products into the cosmetics manufacturer's market, the effects of carbon dioxide, the ease of use of carbonated cosmetics, and novelty and features have become popular among general consumers. As the pharmaceutical products on the market, for example, carbonic acid sheets, carbonated packs, carbonated lotion, carbonated beauty essence, carbonated water, and many other formulations using carbonic acid can be found regardless of the category. Hair care products include styling agents containing carbon dioxide in aerosol type products.

Conventionally, as such an aerosol type product, there is known a product which comprises a stock solution containing an active ingredient and the like and a propellant composed of a liquefied gas or a compressed gas to form bubbles. In such an aerosol type product, a surfactant, a thickener and a polymer are blended in the undiluted solution in order to obtain good foam. However, these components give rise to various problems depending on the type and amount of the components. For example, when the viscosity of the stock solution is high, the stock solution tends to remain in the container, and when carbon dioxide is used as a propellant, a blend of cellulose and gum has a problem that the feeling of foam becomes poor. Therefore, various proposals have been made to solve the above problems.

Patent Document 1 below discloses an aerosol composition in which the pH of the stock solution is kept acidic by carbon dioxide gas which is a volatile acid, and the viscosity is increased by volatilization of the volatile components after ejection.

Patent Document 2 below discloses that in a foam-forming aerosol composition using carbon dioxide gas as a propellant, a hydrophobized hydroxypropylmethylcellulose is blended in a stock solution to obtain a good feeling in use.

Further, in order to improve the styling property of the aerosol formulation, it is known to mix a set resin in addition to the above-mentioned polymer, but when a resin forming a film is mixed, there is a problem that flaking easily occurs. .. Therefore, the following Patent Document 3 discloses a styling aerosol composition comprising a stock solution containing a vinylpyrrolidone/methacrylamide/vinylimidazole/methylvinylimidazolium methylsulfate copolymer and a polyhydric alcohol in a specific ratio and a liquefied gas, It is disclosed that flaking due to the film is suppressed.

Japanese Patent No. 3865831 JP, 2013-170152, A JP, 2008-195669, A

However, the aerosol composition described in Patent Document 1 has a problem that the aerosol can may be corroded because the stock solution is acidic. Further, the foam-forming aerosol composition described in Patent Document 2 may cause a flaking problem depending on the blending amount of hydrophobized hydroxypropylmethyl cellulose, and is not sufficiently satisfactory in foam quality. Furthermore, the styling aerosol composition described in Patent Document 3 was not sufficiently satisfactory in terms of foamability when carbon dioxide gas was used.

In view of the above situation, the present invention is a foamy hair cosmetic composition containing an undiluted solution and a carbon dioxide-containing propellant, which has a good feeling of use and a foam quality, and has an appropriate setting property while being applied to the hair. It is an object of the present invention to provide an aerosol-type foamy hair cosmetic composition capable of suppressing flaking at the time of doing, and having a small residual amount in a container.

The present inventors have conducted extensive studies to achieve the above object, and as a result, in an aerosol-type foamy hair cosmetic composition comprising a stock solution and a propellant containing carbon dioxide, a carboxyvinyl polymer and a water-soluble thickening system. It has been found that the above problems can be solved by combining and blending a polymer, a settable resin compound and a foaming agent in a specific ratio.

Carbon dioxide used in the present invention is one of the compressed gases used as a propellant as in a usual aerosol composition, and the contents are jetted from the aerosol container, slightly dissolved in an aqueous stock solution, and then contained in the atmosphere. It is a component for producing a foam when an object is released.

The aerosol-type foamy hair cosmetic composition is filled in a known aerosol container and is foamed by being discharged from the aerosol container. As the aerosol container, a well-known container can be appropriately selected and used. The method for filling the aerosol is not particularly limited, but a pressure-resistant container is filled with a stock solution prepared by a conventional method, and an aerosol valve is fixed to the container by a known method such as vacuum clinch, and then a propellant is filled. Furthermore, an aerosol product is obtained by attaching an injection member suitable for the purpose to the aerosol valve.

Carbon dioxide gas is preferably blended so that the internal pressure of the aerosol container at a temperature of 35° C. falls within the range of 0.4 MPa to 0.8 MPa (gauge pressure). When the internal pressure of the aerosol container is within this range, good foaming properties can be obtained, and safety as a product can be secured. Carbon dioxide is contained in an amount of, for example, 1.0 to 3.0 parts by mass with respect to 100 parts by mass of the stock solution.

A liquefied gas can be further blended as a propellant in the aerosol container (in the aerosol-type foamy hair cosmetic composition). Further, a compressed gas other than carbon dioxide gas can be further mixed as a propellant in the aerosol container (in the aerosol-type foamy hair cosmetic composition). Examples of the liquefied gas include liquefied petroleum gas (LPG) and dimethyl ether (DME). Examples of the compressed gas include nitrogen gas, air, oxygen gas, nitrous oxide gas, helium gas, neon gas, and argon gas. These propellants other than carbon dioxide gas may be used alone or in combination of two or more, if necessary.

The aerosol-type foamy hair cosmetic composition of the present invention is made into a product form such as a styling foam or a treatment foam, and is particularly suitable as a styling foam.
