Abstract
Liquid and powdered media for active ingredients, and specifically biostatic substrates or bases for the application of anti-microbial compositions, insecticides, and the like. In one embodiment, the present invention provides a composition for use as a substrate that includes powdered clinoptilolite in solution, polyethelenimine in solution, glycerol in solution, and starch in solution. Ingredients such as anti-microbial compounds, insecticides, and/or fragrances can be added to the substrate. In another embodiment, a synthetic zeolite can be substituted for the powdered clinoptilolite. The present invention also provides several methods for making liquid and powdered media, and a method and apparatus for controlling the emission of bacterial odors from a volume of material. Also disclosed are compositions that act as a compatible base or substrate for anti-microbial and other solutions. The present invention provides a safer and more ecologically benign method for anti-microbial applications and enhances the effective life of certain anti-microbials, thus providing a time-released and residual quality unattainable with known water-diluted or solvent-based anti-microbials.
