  • Patent number: 5188822
    Abstract: Oral composition containing an oil-in-water emulsion, wherein the oil phase of the emulsion includes an aminoalkyl silicone and a lipophilic compound and the aqueous phase includes an emulsifier. The lipophilic compound is soluble in the aminoalkyl silicone. Preferably, a lipophilic antimicrobial agent or a lipophilic flavorant is employed. The aminoalkyl silicone forms a substantive film on the teeth surface and the lipophilic compound is deposited, along with the aminoalkyl silicone, on the teeth surface. Thus, the enhanced deposition of the lipophilic compound is attained. The pH of the compositions is preferably at least 7.0. The compositions are preferably applied by brushing.

    Abstract: The present invention relates to compositions and methods for inhibiting plaque. In particular, this invention relates to oral compositions comprising: (a) a safe and effective amount of a carboxy-substituted polymer active agent having the formula ##STR1## or the salts thereof, wherein R is a C.sub.1 -C.sub.8 alkyl group, n is in the range of from 0 to about 2,000, m is in the range of from about 10 to about 2,000, and p is in the range of from about 1 to about 10; and (b) a pharmaceutically acceptable carrier. These compositions inhibit plaque without staining the tooth surfaces which are contacted with the composition.This invention also relates to a method of inhibiting plaque on tooth surfaces in the oral cavity. This method involves applying a safe and effective amount of the carboxy-substituted polymer active agent to the oral cavity. Such an application is typically made by applying the above-described oral compositions containing the carboxy-substituted polymer to the tooth surface.
