Sunscreen compositions containing an ultraviolet radiation-absorbing polymer
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.
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.
