COSMETIC OR PERSONAL CARE FORMULATIONS CONTAINING POROUS METAL OXIDE SPHERES
A cosmetic or personal care formulation includes a carrier and porous metal oxide spheres wherein, the porous metal oxide spheres have,.eg., an average diameter of about 0.5 µm to about 100 µm and an average porosity of about 0.10 to about 0.80; the porous metal oxide spheres have one or more population of pores each having an average pore diameter, wherein each population has a different average pore diameter and wherein the average pore diameters are, e.g., from about 50 nm to about 999 nm.
