To provide a multi-phase oral composition for whitening teeth.SOLUTION: A multi-phase oral composition is provided, comprising: a) an aqueous phase having a bleaching agent, from about 0.9 to 60 wt.% of the multi-phase oral composition, wherein the amount of the bleaching agent in the multi-phase oral composition is 1-5 wt.%, and the bleaching agent is hydrogen peroxide, carbamide peroxide, calcium peroxide, carbamide peroxide, and a mixture of them; and b) a hydrophobic phase from 40 to 99.1 wt.% of the multi-phase oral composition. The multi-phase oral composition has a cone penetration consistency value from 50 to 400 as measured by ASTM D937-07; and the hydrophobic phase has a melting point from 30 to 90°C as measured by ASTM D127-08.SELECTED DRAWING: Figure 1 【課題】歯をホワイトニングするための多相口腔用組成物を提供する。【解決手段】多相口腔用組成物であって、ａ）前記多相口腔用組成物の０．９重量％〜６０重量％の、漂白剤を有する水相であって、前記多相口腔用組成物中の前記漂白剤の量が１重量％〜５重量％であり、前記漂白剤が過酸化水素、過酸化尿素、過酸化カルシウム、過酸化カルバミド、及びこれらの混合物である、水相と、ｂ）前記多相口腔用組成物の４０重量％〜９９．１重量％の疎水相と、を含み、前記多相口腔用組成物が、ＡＳＴＭ Ｄ９３７−０７により測定した場合に５０〜４００の円錐貫入稠度値を有し、前記疎水相が、ＡＳＴＭ Ｄ１２７−０８により測定した場合に３０℃〜９０℃の融点を有する、多相口腔用組成物である。【選択図】図１
