Abstract: A composition for thickening hydrophobic liquids, and for dispersing and suspending partic~ulate materials in a hydrophobic liquid, is dis~closed. Th e composition contains a layered silicate material the surface of which is modified by an adsorbed amphipathic copolymer. The composition typically is dispersed in a hydrophobic liquid or in glycol-water mixture for easy additi on to, and dilution in, hydrophobic liquid-based formulations.

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 th e metal oxides. Another important component of the multifunctional-additive compositions is a dispersant or surface-modifier for the foregoing particula te materials, selected from the family of polyphenolic, natural polymers such a s lignosulfonates, lignins, humates, tannates, and derivatives thereof. In addition, these compositions optionally include one or more of the following components: electrolytes, defoamers, humectants, emollients for cosmetics, preservatives, whiteners, and the like.
