摘要： The present invention provides a W/O nanoemulsion which remains stable even if stored for long periods of six months, for example. The W/O nanoemulsion of the present invention comprises: a) a water content of greater than 0 wt% but no greater than 30 wt%; b) an oil content of less than 100 wt% but no less than 70 wt%; c) 1 to 30 parts by weight of at least one nonionic surfactant for every 100 parts by weight of oil, the nonionic surfactant having an HLB value of 1 to 10; and d) 0.1 to 30 parts by weight of at least one selected from the group consisting of an anionic surfactant, a cationic surfactant, and an amphoteric surfactant, for every 100 parts by weight of water, wherein the average particle size of 50% of the water particles in the W/O nanoemulsion is 100 nm or less.
