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 a linear, ultraviolet radiation absorbing polyether that comprises a chemically covalently bound UV-chromophore and a backbone having glyceryl repeat units; and

an emollient selected from the group consisting of esters of glycerol and silicone oils.

2. The composition of claim 1, wherein the emollient comprises isopropyl palmitate or isopropyl myristate.

3. The composition of claim 1, wherein the emollient comprises dimethicone.

4. The composition of claim 1, wherein the emollient comprises isopropyl myristate and dimethicone.
