The present invention relates to an oral hygiene composition, particularly a dentifrice composition, which contains microcrystalline cellulose surface-treated with a water-soluble substance and displays excellent shape retention and dispersibility in the oral cavity. The oral hygiene composition of the present invention can be favorably placed on a brush such as a toothbrush because it has low stringiness, and also enables blended ingredients to immediately disperse throughout the oral cavity when it is applied to the oral cavity, therefore, an active ingredient can be dispersed throughout the oral cavity for a longer time, and also imparts an excellent feeling for use.本發明係關於包含以水溶性物質表面處理之結晶纖維素，保形性及口腔內分散性優異的口腔用組成物，尤其牙膏組成物。因為本發明之口腔用組成物係低曳絲性，可良好地放置於牙刷等之刷子上，且適用於口腔內時，配合成份可迅速地分散遍佈於口腔內整體，所以可使有效成份更長時間分散遍佈於口腔內整體，可賦予良好的使用感。
