ABSTRACT:
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.
