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.

Claims

1. A composition, comprising:

a continuous water phase,

a discontinuous oil phase homogeneously distributed in said water phase, said oil phase comprising a sunscreen agent comprising a polymer composition, said polymer composition comprising about 50% or more of a linear, ultraviolet radiation absorbing polyether that comprises a covalently bound UV-chromophore, wherein said polymer composition has a polydispersity index of about 1.5 or less; and

an oil-in-water emulsifier component comprising an anionic oil-in-water emulsifier in an amount of about 0.5 percent to about 3 percent by weight of said composition;

wherein said linear ultraviolet radiation absorbing polyether comprises a repeat unit selected from the group consisting of
