Abstract
The present invention provides a sunscreen composition containing (a) a surfactant, (b) water, (c) an oil component, and (d) a water- and/or oil-soluble ultraviolet absorbent, that is in a bicontinuous microemulsion phase at 25° C. The transparent bicontinuous microemulsion spreads well when applied to the skin, to give a uniform and well-absorbed film.
