Abstract
Aqueous compositions including a discontinuous oil phase containing an ultraviolet radiation-absorbing polymer stabilized in a continuous aqueous phase, an oil-gelling polymer, and which are substantially free of non-polymeric ultraviolet radiation-absorbers.
Claims17
A composition comprising:
- a continuous water phase;
- a discontinuous oil phase comprising a UV-absorbing polyester that is formed by a polycondensation reaction of dimerdiol (monomer 1), di-trimethylolpropane (monomer 2), dimethyladipate (monomer 3) and benzenepropanoic acid (monomer 4), in an amount effective to provide said composition with an SPF of about 2 or more in the absence of a UV-screening compound, wherein the mole ratio of the four monomers (monomer 1:
- monomer 2:
- monomer 3:
- monomer 4) is selected from the group consisting of 2.4:3.1:4.0:8.0 and 3.4:2.1:4.0:6.0;
- wherein said discontinuous oil phase is stable in said continuous water phase;
- and an oil gelling polymer, wherein said composition is substantially free of a non-polymeric UV-absorber.
