Patent ID: 6998426

Claim:
An oil-in-water nanoemulsion, comprising: an oily phase dispersed in an aqueous phase; (i) at least one amphiphilic lipid selected from the group consisting of nonionic amphiphilic lipids, anionic amphiphilic lipids, and combinations thereof; and (ii) at least one water-soluble nonionic polymer selected from the group consisting of homopolymers and copolymers of ethylene oxide having a molar mass equal to or greater than 10,000 g/mol; 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–C3 alkyl guar; C1–C3 hydroxyalkyl guar; and combinations thereof; wherein the at least one water-soluble nonionic polymer is free of hydrophobic chains; wherein a ratio of the weight of said oily phase to the weight of said amphiphilic lipid (i) ranges from 1.2 to 10; and wherein said oily phase comprises oil globules having a number-average size of less than 100 nm, wherein the water-soluble nonionic polymer is present in a nanoemulsion thickening effective amount.
