Was.
[0003]
As an attempt to stably blend higher alcohols, Patent Document 1 discloses that a stable emulsion can be obtained by using two or more higher alcohols having 18 or more carbon atoms at a specific blending ratio and amount. . Patent Document 2 discloses a solid water-containing composition comprising a higher alcohol, a lipophilic polyglycerin fatty acid ester, and water, and a solid water-in-oil cosmetic using the same. However, these are solid water-containing compositions and solid water-in-oil cosmetics, which are solid and water-in-oil emulsions, and no studies have been made on oil-in-water cosmetics. Not.
[0004]
On the other hand, Non-Patent Document 1 mentions suppression of crystallization of an oil-in-water emulsion in an oil phase by a lipophilic polyglycerin fatty acid ester. However, this study was conducted on n-hexadecane used as an oil / fat model of an oil phase component, and neither studies on higher alcohols nor studies on multicomponent systems were made.
