  • Oral compositions and method for reducing dental calculus
    Patent number: 5028415
    Abstract: The present invention relates to oral compositions, such as dentifrices, toothpastes and mouthwashes, which provide an anticalculus benefit. These compositions comprise a safe and effective amount of an anticalculus agent which is a polyepoxysuccinic acid, or its pharmaceutically-acceptable salts, along with a pharmaceutically-acceptable carrier. The present invention also relates to a method for inhibiting or reducing the development of dental calculus by contacting the oral cavity with a safe and effective amount of an anticalculus agent which is a polyepoxysuccinic acid, or its pharmaceutically-acceptable salt.
