である。The surfactant to be emulsified is at least one selected from the group consisting of polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitandiolate, polyoxyethylene sorbitan triolate, and sodium salt of polyoxyethylene lauryl ether phosphate. It is a kind of surfactant. These surfactants can be used alone or in combination. These are used in an amount of 15 to 100, preferably 25 to 50 parts by weight per 100 parts by weight of squalene or squalane. If a surfactant is used outside the above range, a stable emulsion composition cannot be obtained even if a carboxylic acid is used. Particularly preferably, polyoxyethylene sorbitan monooleate (the total amount is A) and polyoxyethylene sorbitan triolate (the total amount is B) are used in combination, and the weight ratio A / B of both is 1 or less. Something is appropriate.
