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.
