PROBLEM TO BE SOLVED: To provide an oil-in-water type ultrafine emulsion preparation for external use containing a highly polar dineopentanoic acid polyalkylene glycol and a method for producing the oil-in-water type ultrafine emulsion preparation for external use. SOLUTION: The oil-in-water type ultrafine emulsion preparation for external use comprises (A) a nonionic surfactant having an HLB of≤5, (B) a dineopentanoic acid polyalkylene glycol, (C) water, (D) a nonionic surfactant having an HLB of≥9, (E) a polyoxyethylene-polyoxyalkylene random copolymer dialkyl ether derivative and/or a polyhydric alcohol-polyoxyalkylene glycol-polyethylene glycol copolymer alkyl ether derivative and (F) potassium 4-methoxysalicylate.
