PROBLEM TO BE SOLVED: To provide a method for producing high quality phosphotriester, practically containing none of nasty smell-causing peroxide, carbonyl compound and the like, and usable for perfumeries, cosmetics and the like. SOLUTION: The method comprises reacting an organic hydroxy compound represented by general formula (1): R<SP>1</SP>-O(AO)<SB>n</SB>-H (1) (wherein, R<SP>1</SP>is a 1-12C straight chain or branched chain alkyl; A is a 2-3C straight chain or branched chain alkylene; n is the average added mol number of alkylene oxide and is 1-10; and n A's may be the same or different) with a phosphorating agent, and contacting 20-500 pts.wt. steam to 100 pts.wt. obtained reaction mixture containing phosphotriester by using a batch type distiller at 0.133-13.3 kPa and 80-120°C to produce the phosphotriester having≤0.2 milliequivalent/g peroxide value and≤0.2μmol/g carbonyl value.
