Abstract:
A water-in-silicone oil (W/S) macroemulsion cosmetic composition of waterdrop quick break type is provided. The silicone oil phase part (S) contains a partly crosslinked emulsifiable silicone elastomer, a partly crosslinked non-emulsifiable silicone elastomer, and silicone oil, and the aqueous phase part (W) contains 1,3-butylene glycol and a lower alcohol, and also, at least one member selected from the group consisting of organic acid salts, inorganic salts, and polyhydric alcohols excluding glycerin and 1,3-butylene glycol as a freeze stabilizer at a predetermined composition. The cosmetic composition instantaneously releases water upon application on the skin. The cosmetic composition is stable at the extremely low temperature of −20° C., and it retains its dispersion stability even after repeated freezing and thawing, and accordingly, it can be used in a variety of cosmetic product.
