Claims23
A topical emulsion composition formed by combining components comprising:
- (a) from 1% to about 98% of a hydrophobic phase;
- (b) from 1% to about 98% of a hydrophilic phase;
- and
- (c) from about 0.3% to about 2% of pigmentary grade particulate material having a refractive index of at least about 2 and a neat primary particle size of from greater than 100 nm to about 300 nm wherein said particulate material is selected from the group consisting of TiO2, ZnO, ZrO2 and combinations thereof;
- wherein the total amount of all particulate material in the composition, by weight of the composition, is about 10% or less.
