Description

  The present invention relates to a cosmetic, and more particularly to a cosmetic having a warm feeling effect containing carbonic acid.

Carbon dioxide gas is known to promote blood circulation to the skin, and is commonly used in bath preparations. After dissolving the bath agent in hot water, it foams and dissolves in the water, so that the blood circulation of bathing is achieved. The effect which improves acceleration is reported, and such a bath agent is normally used as an effervescent tablet and a granule (for example, refer patent document 1).

Carbon dioxide gas is used as a bathing agent, and is also widely used in cosmetics (for example, Patent Document 2). In recent years, many pack cosmetics containing carbon dioxide that can be used easily have been developed, and in addition to the moisturizing effect of the occlusion effect provided by the pack, cosmetics that have a blood circulation promoting effect have attracted attention and are commercially available (for example, patents) Reference 3). Originally, in foam cosmetics, a gas component is an essential component, and as the gas component, chlorofluorocarbon has been used for many years. Has been used as a substitute for such Freon gas, and its physiological effect has also been utilized. When carbon dioxide gas is selected as an alternative to such a fluorocarbon gas, the strength of the discharged foam and the foam retention properties have been major issues. In CFCs, higher alcohols such as cetanol, fatty acids, and the like have been used as structure-forming components.

Solid fats such as hydrocarbons, fatty acid esters, higher alcohols and the like have been blended in cosmetics as an oily component that is expected to have an emollient effect. However, there is a problem in use that makes a film feel when used (for example, Patent Document 4). reference).

Solid fat has never been used for the purpose of forming a foam structure in a foam-forming cosmetic. This is because the structure-forming component of foam usually requires a surface-active action to be coordinated at the interface, and such an action was not observed in solid fats in ordinary cosmetics.

Therefore, it is a foamed aerosol dosage form comprising 1) carbon dioxide gas 0.05 to 5% by mass, and 2) 0.1 to 10% by mass of hydrocarbon and / or fatty acid ester as solid fat. The fee was not known at all.

  According to the present invention, it is possible to provide a foam cosmetic that contains carbon dioxide and has a good feeling of use.

This invention is a foaming aerosol dosage form, 1) Carbon dioxide gas 0.05-5 mass%, 2) As solid fat, hydrocarbon and / or fatty acid ester contain 0.1-10 mass%. Features.
(1) Carbon dioxide gas which is an essential component of the foam cosmetic of the present invention (also referred to as foamed aerosol dosage form) The foam cosmetic of the present invention is a foamed aerosol dosage form, and carbon dioxide gas as a gas component for foaming. Containing. Due to the secondary effect of carbon dioxide, the cosmetic of the present invention promotes blood flow and becomes a cosmetic having a warm feeling. The foam cosmetic of the present invention can contain components such as LPG, dimethyl ether, and fluorocarbon in addition to carbon dioxide, as long as the effects of the present invention are not impaired. Since there may be cases where it is induced or there is a case where the blood circulation promoting effect, which is a secondary effect of carbon dioxide, may be impaired, it is preferable to use only carbon dioxide. The compounding amount is preferably adjusted so that the gas pressure of the gas containing carbon dioxide is 0.1 to 1 MP in a state filled with an aerosol can together with other cosmetic ingredients, and 0.3 to 0.7 MP. Is more preferable. Such pressure adjustment can be realized by filling the aerosol can together with other cosmetic ingredients as a gas containing carbon dioxide gas until the gas pressure is balanced. As a result of such pressure adjustment, the content of carbon dioxide is 0.5 to 10% by mass, more preferably 0.5 to 2% by mass, based on the total amount of cosmetics including carbon dioxide. is there. This is because if the amount of gas is too large, the bubbles cannot contain the gas and foam does not form, and if the amount of gas is too small, foaming may be difficult.

(2) Solid fat that is an essential component of the foam cosmetic of the present invention The solid fat of the present invention is an oily component that maintains its form at 20 ° C., and means a component that does not have a surface active action.
