摘要：
The present invention is directed to an aqueous dispersion comprising: (a) at least one solid wax particle having a particle size ranging from equal to or greater than 1 micron to about 100 microns, and comprising at least one wax having a melting point of greater than 35° C. (b) a surfactant mixture comprising at least one nonionic surfactant and at least one ionic surfactant (c) at least one sunscreen agent and (d) water. The aqueous dispersion may be employed in compositions capable of delivering photoprotective benefits to various substrates, for example, keratinous substrates such as skin and hair.
