Title: METAL OXIDE OIL DISPERSION SUNSCREEN FORMULATIONS
Abstract:
A sunscreen formulation comprises an oil carrier, a particulate metal oxide sunscreen active agent and a polymeric rheology modifier that maintains the particulate sunscreen active agent in a stable dispersion in the formulation. In one aspect the polymeric rheology modifier is obtainable by co-polymerizing a monomer mixture comprising at least one alkyl (meth)acrylate and at least one of the following monomers: a bicyclic (meth)acrylate ester different from the alkyl (meth)acrylate, and an aromatic vinyl monomer. In one embodiment the polymeric rheology modifier is crosslinked.
