## Abstract

Disclosed is a leave-on water-in-oil cosmetic emulsion that includes an aqueous phase comprising water and a hydrophilic thickening agent consisting of polyvinylpyrrolidone, the aqueous phase being free of other hydrophilic thickening agents, a mattifying filler including a silicone elastomer, an organic ultraviolet filter consisting of octyl salicylate, at least one silicone oil, and at least one silicone emulsifier.

## Claims

### Claim 1

A leave-on water-in-oil cosmetic emulsion, comprising:
an aqueous phase comprising water and a hydrophilic thickening agent consisting of polyvinylpyrrolidone, the aqueous phase being free of other hydrophilic thickening agents;
a mattifying filler comprising a silicone elastomer;
an organic ultraviolet filter (UV) consisting of octyl salicylate;
at least one silicone oil;
at least one silicone emulsifier; and
optionally, an inorganic UV filter consisting of UV-grade titanium dioxide.
