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 about 15% or more by weight of a UV-absorbing polyester, which UV-absorbing polyester is the polymerization reaction product of four monomers comprising (1) dimerdiol (“
DDO”
), C36H72, CAS No. 147853-32-5;
(2) di-trimethylolpropane (“
DITMP”
), C12H26O5, CAS No. 23235-61-2;
(3) dimethyladipate (“
DMA”
), C8H14O4, CAS No 627-93-0; and
(4) benzenepropanoic acid, 3-(2h-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxy-methylester (“
triazole”
) C20H23N3O3, CAS No 84268-33-7, wherein the molar ratio of the four monomers (DDO;
DITMP;
DMA;
triazole) is 3.4;
2.1;
4.0;
6.0,about 0.3 to about 3% by weight of an alkylated polyvinylpyrrolidone; and
an oil-in-water emulsifier selected from the group consisting of an anionic emulsifier and a non-ionic emulsifier, wherein, if said oil-in-water emulsifier comprises said anionic emulsifier, said anionic emulsifier is present at from about 0.5% to about 6% by weight, and wherein if said oil-in-water emulsifier comprises said non-ionic emulsifier, said non-ionic emulsifier is present at from about 1% to about 10% by weight and is free of an oil-gelling polymer; and
wherein said composition comprises less than 1% by weight of a non-polymeric UV-absorbing sunscreen agent, has an SPF of less than 2 in the absence of said UV-absorbing polyester, an SPF of about 20 or greater and a Water Resistance Value of greater than 65%.

Abstract
Compositions including an oil phase substantially homogeneously distributed in a continuous water phase, the oil phase including a sunscreen agent that includes a UV-absorbing polyester in an amount effective to provide the composition with an SPF of about 10 or greater and which is the polymerization reaction product of monomers including a UV-absorbing triazole, a diester, a diol and a tetrol polyol; an alkylated polyvinylpyrrolidone; and an emulsifier selected from anionic emulsifier and/or a non-ionic emulsifier, where the composition is substantially free of a non-polymeric UV-absorbing sunscreen agent and has an SPF of less than 2 in the absence of the UV-absorbing polyester.
