Abstract

Compositions including a discontinuous oil phase homogeneously dispersed in a continuous water phase, the oil phase including a sunscreen agent that includes a linear, ultraviolet radiation absorbing polyether that comprises a chemically bound UV-chromophore; and an oil-in water emulsifier component including an anionic oil-in-water emulsifier and a nonionic oil-in-water emulsifier having an alcohol functional group, wherein the weight ratio of the anionic oil-in-water emulsifier to the nonionic oil-in-water emulsifier is about 12 or less and wherein the linear, ultraviolet radiation absorbing polyether is present in an amount effective to provide the composition with an SPF of about 10 or greater.

Claims

1. A composition, comprising:

a continuous water phase,

a discontinuous oil phase homogeneously distributed in said water phase, said oil phase comprising a polymer composition having a polydispersity index of about 1.5 or less, said polymer composition comprising a sunscreen agent comprising a linear, ultraviolet radiation absorbing polyether that comprises a covalently bound UV-chromophore, wherein said linear, ultraviolet radiation absorbing polyether is present in an amount effective to provide said composition with an SPF of about 10 or greater, wherein said polymer composition comprises about 50% or more of said linear ultraviolet radiation absorbing polyether; and

an oil-in-water emulsifier component comprising an anionic oil-in-water emulsifier and a nonionic oil-in-water emulsifier having an alcohol functional group, wherein the weight ratio of the anionic oil-in-water emulsifier to the nonionic oil-in-water emulsifier is about 12 or less;

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