More Information
Summary:A spermicidally-active vaginal suppository consisting essentially of a solid water-soluble polymeric material which melts at body temperature, for example, a polyethylene glycol, having dispersed therein minor amounts of a spermicide, for example, p-nonylphenoxypolyethoxyethanol, a foaming agent operative when the suppository is dissolved in aqueous media to generate a foam-forming gas, for example, a mixture of a water-soluble bicarbonate and a solid weak acid, and a foam-stabilizing agent which is characterized by containing a surfactant, which is effective to reduce the surface tension of water to less than 45 dynes per centimeter, for example, sodium lauryl sulfate, and lactalbumin.
