PROBLEM TO BE SOLVED: To provide an alkylene oxide-added composition which has excellent safety and little emits an odor. SOLUTION: This alkylene oxide-added composition has a dioxane content of≤4 ppm, an ethylene glycol content of≤20 ppm, a diethylene glycol content of≤20 ppm, an aldehyde content of≤2 ppm, and an unreacted alkylene oxide content of≤1 ppm. Preferably, the alkylene oxide-added composition is produced by obtaining a low mol. wt. alkylene oxide-added composition (A1), adding a catalyst, stripping the mixture under reduced pressure, addition-reacting an alkylene oxide to obtain the high mol. wt. alkylene oxide-added composition, and then subjecting the product to a purification process.
