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.

Abstract: A controlled delivery system for active ingredients, like a fragrance, for use in fabric softener products, such as tumble dryer sheets, rinse added liquids, and similar products, is disclosed. The delivery system enhances performance of an active ingredient, such as a fragrance. The controlled delivery system contains polymeric micro-particles highly loaded with the active ingredient. Other active ingredients that can be incorporated into a fabric softener composition using the delivery system include ironing aides, silicone fluids, antiwrinkle agents, antistatic agents, optical brighteners, fabric crisping agents, bleaching agents, germicides, fungicides, flow agents, and surfactants.
