Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning material which is friendly to the mucous membranes of the oral cavity and has improved cleaning force by forming a sponge of the refined powder of devil's tongue and/or glucomannan as a chief base material. SOLUTION: For example, about 3 g 1% aqueous solution of the glucomannan is dissolved in about 100 g water. About 2.0 ml calcium hydroxide suspension is added thereto to cause swelling. The solution is then heated in hot water to gelatinize the solution and is thereafter frozen. The devil's tongue sponge is formed by thawing and dehydrating the frozen solution. The cleaning material for the oral cavity is blanked and formed from the devil's tongue sponge. When the cleaning member for the oral cavity is subjected to an evaluation test by a physical cleaning force evaluation method, the gingiva and the palate are kept free from stimuli and pain even if the mucous members of the oral cavity are strongly rubbed. The better results than by gauge and tooth brushes are obtained. The cleaning of the mucous members of the oral cavity without the damage thereto is thus made possible.
