An oral composition comprises water and a cyclic carbonate compound in a certain
ratio. In this case, the ratio of the water and the cyclic carbonate compound is
such that when the water and the cyclic carbonate compound are mixed together the
mixture goes into a 2-phase state. Moreover, the oral composition may further comprise
a polyol, and in this case the ratio of the water, the cyclic carbonate compound
and the polyol is such that when the water, the cyclic carbonate compound and the
polyol are mixed together the mixture goes into a 2-phase state. The oral composition
has an excellent effect of removing accumulations on dental surfaces or between
teeth through a physico-chemical action, rather than relying purely on a mechanical action.
