Abstract
Abstract A water-in-oil type cosmetic composition comprising a cosmetic oil base material, water and a specific emulsifier are disclosed. The specific emulsifier comprising the following three components: (1) 94 to 43% by weight of α-mono(methyl-branched alkyl) glyceryl ether represented by the formula (I): R--OCH.sub.2 CH(OH)CH.sub.2 OH (I) where, R is a methyl-branched saturated hydrocarbon group having 14 to 20 carbon atoms; (2) 0.4 to 9.8% by weight of a multi-valent metal salt of a saturated or unsaturated aliphatic acid having 10 to 22 carbon atoms; and (3) 8 to 54% by weight of at least one inorganic or organic salt having a solubility in water of at least 0.2 g per 100 g of water at 20° C.
