Abstract
Compositions including a discontinuous oil phase homogeneously dispersed in a continuous water phase, the oil phase containing a sunscreen agent that includes a polymer composition containing a linear, ultraviolet radiation absorbing polyether, the linear, ultraviolet radiation absorbing polyether including a chemically bound UV-chromophore; and an oil-in water emulsifier component including an anionic oil-in-water emulsifier in an amount such that the composition includes about 0.5 percent by weight to about 3 percent by weight of the anionic oil-in-water emulsifier.
