ABSTRACT:
Stable and homogeneous, topically applicable sunscreen/cosmetic compositions well suited for the photoprotection of human skin and/or hair against the damaging effects of UV-A and/or UV-B irradiation, particularly solar radiation, and which display excellent transparency on the skin, comprise a storage-stable, ultrafine oil-in-water emulsion of a photoprotecting effective amount of homogeneously and finely dispersed particulates of at least one inorganic nanopigment which comprises a metal oxide, for example titanium dioxide, wherein the average particle size of the globules comprising the oily phase of the emulsion characteristically range from 100 nm to 1,000 nm.
