Provided is an oral composition that has low irritation to the oral mucosa and gums and does not cause a slimy feeling or taste change in the oral cavity after use. An oral composition containing 0.01 to 10% by mass of an alkylene oxide derivative represented by the following general formula (I) and 0.1 to 20% by mass of an anionic surfactant. [Chemical 1] (In the formula, AO is an oxyalkylene group having 3 to 4 carbon atoms, and EO is an oxyethylene group, which may be added in blocks or randomly. M and n are AO and EO, respectively. 1 ≦ m ≦ 70, 1 ≦ n ≦ 70, the ratio of EO to the total of AO and EO is 20 to 80% by mass, R 1 and R 2 may be the same or different, and The number of hydrogen atoms to the number of hydrocarbon groups of R 1 and R 2 is 0.15 or less. |
