Abstract
The present invention relates to the use of a bioadhesive aqueous composition to control the pH of the vagina to alleviate microorganism growth and feminine odor such as presented by bacterial vaginosis. The composition contemplated herein comprises water and an acidic polymer, specifically one wherein 80% of the monomers contain at least one carboxyl group [--COOH] and wherein the polymer is cross-linked so as to be water-swellable, but water-insoluble. The composition of the present invention is additionally a bioadhesive providing for a long-lasting benefit and control of vaginal pH.
