    Abstract: A cosmetic composition in the form of an oil-in-water emulsion methods of using and producing cosmetic compositions is provided. The cosmetic composition includes an aqueous phase, an oil phase comprising a water-in-oil emulsifier, and an oil stabilizing component. The water-in-oil emulsifier is at concentration, by weight, of about 0.01% to about 6.0%, based upon weight of the composition. The oil stabilizing component includes one or both of an amphiphilic compound or a surfactant having an HLB of 13 or greater added to the aqueous phase. The oil stabilizing component is at a concentration, by weight, of about 0.01% to about 1.0%, based upon weight of the composition. The oil-in-water emulsion has an increased water load relative to water-in-oil emulsions without having an increased viscosity.

    Abstract: These objects and others may be accomplished with the present invention, the first embodiment of which provides an oil-in-water nanoemulsion, which includes: an oily phase dispersed in an aqueous phase; (i) at least one amphiphilic lipid selected from the group including nonionic amphiphilic lipids, anionic amphiphilic lipids, and combinations thereof; and (ii) at least one water-soluble nonionic polymer selected from the group including homopolymers and copolymers of ethylene oxide; polyvinyl alcohols; homopolymers and copolymers of vinylpyrrolidone; homopolymers and copolymers of vinylcaprolactam; homopolymers and copolymers of polyvinyl methyl ether; neutral acrylic homopolymers and copolymers; C1-C2 alkyl celluloses and their derivatives; C1-C3 alkyl guar; C1-C3 hydroxyalkyl guar; and combinations thereof; wherein a ratio of the weight of the oily phase to the weight of the amphiphilic lipid (i) ranges from 1.2 to 10; and wherein the oily phase includes oil globules having a number-average size of less than 100 nm. The nanoemulsion obtained is preferably transparent and stable on storage. It may form a composition for topical, preferably cosmetic or dermatological compositions, pharmaceutical compositions and ophthalmological compositions.
