Abstract: Cosmetic and personal care compositions can be manufactured using the multifunctional-additive compositions of the present invention. Such an additive preferably contains one or more particulate-based thickeners, such as a smectite clay, colloidal silica, laponite, and/or alumina, and most preferably one or more smectite clays. According to one important embodiment of the present invention, the thickener particles are co-dispersed with particles of one or more particulate UVR-filters such as titanium dioxide, zinc oxide, or SUNSPHERE (available from International Specialty Chemicals, ISP), and most preferably with the natural particulate sunscreens such as the metal oxides.
