A foamable cosmetic product filled in a nonmetal pressure-resistant container having a spout, which generates a vapor pressure that can be spouted from the container when heated to 0 ° C.

[0006] The foamable cosmetic composition containing water,
For example, an oil-in-water emulsion type cosmetic composition is not particularly limited as long as it is effervescent, and examples thereof include effervescent cosmetic compositions such as shaving foams, creams, foundations, and emulsions.

[0007] The foamable cosmetic composition is an oil-in-
In the case of a water-type emulsion type composition, it is non-greasy and gives a crisp feel, and since it is a foamable composition, it is easy to spread.

In order to make the cosmetic composition an oil-in-water emulsion type cosmetic composition,
It is necessary that the composition contains at least an oil component to be emulsified (oil component), water serving as a medium, and an emulsifier, and in order to obtain a foamable composition, It is necessary that at least a foaming agent be contained in the composition.

The oils to be emulsified include oils and fats such as castor oil and olive oil, waxes such as spermaceti and lanolin, liquid paraffin, hydrocarbons such as squalane and petrolatum, stearic acid, and myristine. Acids, fatty acids such as coconut oil fatty acids, higher alcohols such as lanolin alcohol, cetostearyl alcohol, cetanol and oleyl alcohol, fatty acid esters such as isopropyl myristate, butyl stearate, glycerin monostearate and propylene glycol monolaurate And silicone oils such as methylpolysiloxane.

The water is used not only as a medium but also for improving the efficiency when the foamable cosmetic product of the present invention is heated to a predetermined temperature by electromagnetic waves (microwaves) such as a microwave oven. It is used to reduce flammability at the time and to give an excellent feeling of use (non-stickiness, ease of washing, etc.).

Examples of the emulsifier include ester emulsifiers such as polyglycerin fatty acid esters, ether emulsifiers such as polyoxyethylene alkyl ether, polyoxyethylene hydrogenated castor oil, polyoxyethylene monooleate, and monostearic acid. Nonionic emulsifiers such as ether ester type emulsifiers such as polyoxyethylene sorbitan; fatty acid soaps such as sodium laurate and sodium stearate; anionic emulsifiers such as polyoxyethylene alkyl ether sulfate; benzalkonium chloride and benzethonium chloride Cation-type emulsifiers such as alkyltrimethylammonium chloride and dialkyldimethylammonium chloride can be used. From the viewpoint of no, nonionic type of emulsifier is preferred.

As the foaming agent which also acts as a propellant, a paraffin-based hydrocarbon having a boiling point of 10 to 90 ° C., and more preferably 20 to 80 ° C., provides a suitable warm feeling during use and is easy to use. This is preferred from the viewpoint of: If the boiling point is too low, it will have a vapor pressure that can be ejected from the container even at room temperature, and will not be different from conventional aerosol products. Also, when used, the feeling of cooling becomes stronger. On the other hand, if the boiling point is too high, it is necessary to heat the water to around the boiling point at the time of use, which causes burns.

The foaming agent can be used without any particular limitation as long as it has a boiling point within a predetermined range and has no problem such as high toxicity or irritation which is inappropriate as a raw material for a foamable cosmetic composition. Specific examples of preferable foaming agents include, for example, n-pentane, 2-methylbutane, n-hexane,
Linear or branched alkanes having 5 to 6 carbon atoms, such as -methylpentane, 3-methylpentane, 2,2-dimethylpentane, and 2,3-dimethylpentane.

The above-mentioned foaming agent is contained as a direct mixture in a water-containing cosmetic composition, for example, an oil-in-water type emulsion.
Since the temperature is 90 ° C., and more preferably 20 to 80 ° C., the pressure does not normally become high at normal temperature unlike a propellant used for aerosol products, and there is no need to use a highly pressure-resistant container. In addition, it does not feel very cold due to heat of vaporization at the time of injection.

The proportion of each component in the foamable cosmetic composition is, for foamable shaving foam,
Water 40-80%, further 50-70%, emulsifier 0.2
-20%, more preferably 1.0-10%, humectants such as propylene glycol, butylene glycol, and glycerin as active ingredients, 1-30% such as fragrance, and 3-20
