[0006] However, there is a possibility that the speed of gelation and / or the hardness of the gel of the composition for preparing a carbon dioxide external preparation may vary depending on the kind and proportion of the gelling agent and the water-insoluble or hardly water-soluble calcium salt. inappropriate question
That is, if the gelation is too fast, there is a problem that the spreadability of the composition used to prepare the carbon dioxide external preparation is applied to the skin, etc., and a sufficient amount of carbon dioxide cannot be generated.
On the contrary, if the gelation is too slow, there is a problem that it is difficult to peel off the composition for preparing a carbon dioxide external preparation from the skin surface by hand, and it is difficult to use it as a mask preparation.

[0046] Compositions for preparing carbon dioxide external preparations were prepared according to the compositions described in Table 1. It should be noted that in the examples in which magnesium carbonate containing both magnesium salt and carbonate is used, the composition for preparing carbon dioxide external preparations is prepared with the amount of magnesium carbonate recorded in the table, but in claim 4, Under the compounding conditions of the essential components such as paragraph 0034 and paragraph 0035, it can be considered that magnesium salt and carbonate are respectively blended in equal amounts.
[0047] According to the compounding quantity described in Table 2, the formulation divided into 2 types was stirred and mixed until it became visually uniform just before use.

Abstract
The present invention addresses the problem of providing a novel composition for preparing carbon dioxide formulation for external use, said composition being highly spreadable on the skin immediately after mixing two or more agents until applying to the skin while preventing the surface of the applied composition from beginning to solidify, being capable of gelling so that the composition can be separated from the skin without remaining on the skin at the end of the use, and, during use period, generating membrane permeable carbon dioxide in an amount greater than the amount of membrane permeable carbon dioxide generated by a conventional composition for preparing carbon dioxide formulation for external use that comprises known components. Also, the present invention addresses the problem of providing a carbon dioxide formulation for external use and a cosmetic pack that are obtained from the novel composition for preparing carbon dioxide formulation. The composition for preparing carbon dioxide formulation at least comprises, as essential components, a gelling agent that gels in the presence of a magnesium salt, a water-soluble calcium salt, magnesium ion or calcium ion, a carbonic acid salt, a substance that generates an acid when hydrolyzed, a polyhydric alcohol and water.
Description
technical field [0001] The present invention relates to a composition for preparing a carbon dioxide external preparation mixed when using two or more preparations. Background technique [0002] There is known a technique of mixing an alkaline composition containing carbonate and an acidic composition such as a water-soluble acid in the presence of water for the purpose of cosmetic and medical effects (see Patent Document 1, etc. ). [0003] In addition, there is also known a method that contains, as essential components, a substance that generates an acid through hydrolysis, a carbonate, a thickener, water, a gelling agent gelled by calcium ions, and a water-insoluble or poorly water-soluble calcium salt, Therefore, it is possible to easily prepare a carbon dioxide external preparation that continuously absorbs carbon dioxide percutaneously and transmucosally, and has stronger cosmetic and medical effects (see Patent Document 2, etc.). [0004] The composition used to pre...
