Abstract: A low-viscosity Pickering water-in-oil emulsion having a viscosity of less than 3000 mPa·s, comprising (1) an oil phase, (2) a water phase, (3) at least one type of microfine, inorganic metal oxide particles a) having an average particle size of less than 200 nm, b) exhibiting both hydrophilic and also lipophilic properties, c) dispersible both in lipophilic and also in hydrophilic liquids and d) optionally surface-coated, (4) 0.01 to 5% by weight of at least one polymeric nonionic and/or cationic thickener and (5) at most 0.5% by weight of one or more emulsifiers.

Abstract: A process for preparing an O/W emulsion concentrate. The process comprises subjecting an O/W emulsion comprising 20% to 95% by weight of one or more lipids, 0.5% to 80% by weight of microfine amphiphilic metal oxide particles, amphiphilic polymer particles, and/or modified polysaccharide particles and water to spray-drying and/or freeze-drying.
