Description

  The present invention relates to a cosmetic, and more particularly to a foamed cosmetic having an exothermic action.

One of the important factors during makeup, such as packs or massages, is the feeling of warmth. This is because the effect expected in such a makeup act has a blood circulation promoting effect, and by feeling warmth, the actual feeling of such an effect is realized, and as a result, the makeup act itself is greatly satisfied. This is because a feeling of warmth and a feeling of moderate warmth embody the comfort of use, and this pleasant sensation prepares the environment of a personal ecosystem and exerts favorable effects on health. The embodied method and by techniques known traditional and of such warming, lysis is contained polyhydric alcohol such as a large amount of glycerin in cosmetics, it occurs when the glycerin is miscible with water of the biological A method using heat (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3) and a chemical reaction heat generated when oxidized by water contained in a living body by containing reduced iron oxide However, since the heat of dissolution has a small amount of heat generated, it has a disadvantage that the feeling of warmth is not sufficient, and the heat of chemical reaction caused by the oxidation reaction. However, it is difficult to control the amount of heat generated, and it has the disadvantage of releasing a large amount of iron ions that may cause allergies. Therefore, it is desired to develop warm cosmetics that improve these disadvantages. It was. Among such warming cosmetics, those which are of particular interest, the two compositions of a composition comprising a composition and click enoic acid containing magnesium oxide and / or zinc oxide as liquefied natural gas, respectively There are cosmetics of the type that are housed in separate chambers and are simultaneously discharged, reacted, and foamed from the two chambers during use. (For example, refer to Patent Document 5) Although this technique has an advantage obtained by controlling a preferable temperature, such a technique has a drawback that the generation of heat rapidly declines. That is, the two compositions of a composition comprising a composition and click enoic acid containing magnesium oxide and / or zinc oxide as liquefied natural gas, housed in independent chamber, discharged simultaneously from two chambers in use, It has been desired to develop a means for extending the heat generation maintenance time of the reaction and foaming type cosmetics.

On the other hand, the two compositions of a composition comprising a composition and click enoic acid containing magnesium oxide and / or zinc oxide as liquefied natural gas, housed in independent chamber, discharged simultaneously from two chambers in use, In the type of cosmetic that is reacted and foamed, the surface of magnesium oxide and / or zinc oxide has not been treated, and the composition contains magnesium oxide and / or zinc oxide and liquefied natural gas that have been treated. the two compositions of a composition comprising an object and click-enoic acid, housed in independent chamber, discharged simultaneously from two chambers in use, reaction, the type of cosmetic to be foaming, temperature controllability and heating time It was not known at all that it was excellent in maintainability. In addition, the structure of a pressure vessel having two independent chambers connected by the above-described discharge ports is already known (see, for example, Patent Document 6, Patent Document 7, and Patent Document 8). There are also commercial products.
