Description

Spumous skin coating agent

Technical field

The present invention relates to contain the spumous skin coating agent of carbon dioxide.

Background technology

Because carbon dioxide (carbonic acid gas) acts on skin and can promote blood circulation of skin, so proposed the various cosmetics that contain carbon dioxide.For example, disclose in containing the cosmetics of carbon dioxide, supplied with the carbon dioxide of saturated concentration once, in addition, under coexistences such as the ethanol that shows high dissolubility, supplied with the method (patent documentation 1) of the carbon dioxide saturated solution of higher concentration than water.Be also known as the volatilization that suppresses carbon dioxide, (patent documentations 2～3) such as methods that atomizing of liquids is remained on full-bodied method and for carbon dioxide is remained on high concentration polyhydric alcohol coexisted with high concentration.

On the other hand, in multiple aerosol,, use with propane, iso-butane and normal butane to the liquefied petroleum gas (LPG) of composition as jet gas in order to form foam.But liquefied petroleum gas exists that inflammability is strong, the problem of foaminess difference during low temperature.As the technology that is used to address this problem, for example, known in the aqueous stock solution that contains moisture and surfactant, liquefied petroleum gas, contain carbonic acid gas, even and obtain fire safe foaminess when the low temperature is not had the pharmaceutical aerosol foam composition (patent documentation 4) of difference yet; With respect to 100 quality % stock solutions, add the liquefied gas of 0～4 quality %, and add compression gas such as carbonic acid gas to carry out supercharging and the noninflammability aerosol type foamed product (patent documentation 5) that obtains.In addition, known in the stock solution that contains the effective ingredient aqueous solution, contain the propellant that only constitutes by normal butane and carbonic acid gas, and the inflammability that obtains is low, than the good foaming characteristic aerosol composition (patent documentation 6) of low temperature foaming characteristic excellence, high temperature safety that uses liquefied petroleum gas, but the price of normal butane is higher.

Also known a kind of foaminess cutaneous circulation promoter, it act as the aerosol agent of purpose for what use carbonic acid gas and hydrocarbon ils simultaneously with blood circulation promoting, in carbon dioxide, use specific hydrocarbon such as isopentane, pentane, improve the bubble persistence (patent documentation 7) of foam, but the then not record of action effect during for holding bubble and making drops in the pressure vessel under the low temperature.
