PROBLEM TO BE SOLVED: To provide a composition for oral care, which has a sufficiently high effect of reducing bacteria present in the oral cavity.SOLUTION: The composition for oral care is a gum. The gum is almost the same as an ordinary gum, and is obtained by adding fine particles, formed by an electret material in which a part thereof is charged positively beforehand, to ordinary gum. When the gum is put into the oral cavity and is chewed, bacteria in the oral cavity, in which the surface of a cell membrane is charged negatively, are drawn by the part charged positively in the fine particles, are stuck to the fine particles, and are exhausted to the outside of the body together with the fine particles or die in the oral cavity or in the digestive organ. Thereby, the gum reduces bacteria present in the oral cavity.COPYRIGHT: (C)2013,JPO&INPIT【課題】口腔内に存在する細菌を減少させる効果が十分に高い口腔ケア用組成物を提供する。【解決手段】口腔ケア用組成物はガムである。このガムは、通常のガムと殆ど同じであり、通常のガムに、予めその一部が+に帯電させられたエレクトレット材料で形成の微粒子を添加したものとなっている。ガムを口腔内に入れて噛むと、細胞膜の表面が-に帯電した口腔内の細菌は、微粒子の+に帯電した部分に引き寄せられて微粒子に付着し、微粒子とともに体外に排出され、又は口腔内か消化器内で死滅する。これにより、このガムは、口腔内に存在する細菌を減少させる。【選択図】なし
