Japanese Patent JP3660717

B2

PROBLEM TO BE SOLVED: To obtain a composition for the oral cavity, useful for preventing dental caries and periodontosis and causing a low level of discoloration with time.
SOLUTION: This composition for the oral cavity is obtained by blending 0.1-20wt.% polyoxyethylene hardened castor oil and 0.01-2wt.% metallic salt of copper chlorophyllin (e.g. sodium copper chlorophyllin) in a composition for the oral cavity containing 0.001-5wt.% green tea extract. The green tea extract is prepared by pulverfzing a dried green tea leaf, extracting the pulverized and dried green tea leaf with water or an alcohol at ambient temperature, distilling away the solvent from the extract solution, then adding water thereto, dissolving the resultant residue, reextracting the obtained solution with a nonpolar organic solvent (e.g. ethyl acetate) and drying and powdering the resultant extract solution separated with the nonpolar organic solvent. Furthermore, usually used various additives are suitably blended therewith according to the kind of the composition for the oral cavity and prepared into a dentifrice, a mouthwash, a refreshing agent in the mouth, a troche, a pasta agent, a chewing gum, a candy, etc.
