Abstract: A method of delivery of active substances to a water-filled environment, specifically a toilet bowl, with a water-soluble polymer as the primary delivery means. The present invention is activated by placement in the water, with the soluble polymer protecting the skin from exposure to the active ingredients. The soluble polymer is composed of a bi-layer capsule or tablet, preferably, with a solid, gas, gel, or liquid core.
