PROBLEM TO BE SOLVED: To solve the problems in which: an oil constituent with a lot of carbon dioxide gas dissolving amounts enhances capillary circulation of the skin surface by an effect of carbon dioxide gas as with carbonic water when being applied on a skin it has been found that permeation rate of the carbon dioxide gas through the skin is slower than that of the carbonic water when judging from a degree of skin flushing phenomenon and the permeation rate of the carbon dioxide gas is increased to be nearly the same as that of the carbonic water so as to improve characteristics as a cosmetic oil.SOLUTION: The above problem is solved by making an oil constituent into an oil-in-water type emulsion so that a phase directly contacting with a skin becomes a water phase.COPYRIGHT: (C)2016,JPO&INPIT【課題】炭酸ガスの溶解量が大きい油成分は皮膚に塗布すると炭酸水と同様に炭酸ガスの作用により皮膚表面の毛細血管の血行を促進する作用がある。しかしながら、皮膚を通しての炭酸ガスの透過速度を皮膚の潮紅現象の程度から判断すると炭酸水に比べて遅いこが解った。この速度を炭酸水と同程度にすることで美容オイルとしての特性向上を課題とした。【解決手段】油成分を水中油型のエマルジョンとすることで、皮膚と直接接触する相が水相となり上記課題は解決された。【選択図】なし
