  • Patent number: 6136768
    Abstract: A water-dispersible effervescent drain cleaner having a composition of approximately 20-60% by weight of a mixture of metal hydroxides, 20-40% hypochlorite generator, and 10-40% effervescent materials. Lubricant, colors and fragrances may also be present. The components of this mixture are compressed into tablet, pellet, granules, or high density powder forms. The particles are of sufficient density to drop through water to the point of a clog. The effervescent materials work to break up the tablets or pellets and to agitate the mixture. The hypochlorite generator, in conjunction with the hydroxides reacts to dissolve hair. The hydroxide and hypochlorite generate heat, which will dissolve grease and soap clogs and accelerate the dissolution of hair.

  • Patent number: 6126697
    Abstract: Carpeting, upholstery, drapery and other textile fibers are cleaned by applying to the fibers, from a pressurized container, an aqueous internally carbonated non-surfactant cleaning composition prepared by admixing, by volume, about 125 ml (150 grams) of an alkaline metal bicarbonate or percarbonate salt, about 62.5 ml (57.4 grams) of a carbonate salt and about 187.5 ml (165 grams) of a natural solid acid, in an aqueous medium such that the natural solid acid reacts with the carbonate/bicarbonate salts to produce carbon dioxide and the solids concentration in the solution resulting from the carbonate salts and natural solid acid forming the basis of the cleaning solution. Citric acid, sodium carbonate and sodium bicarbonate are the preferred solid acid and carbonate salts. The composition is prepared from naturally occurring ingredients and the container is pressurized by air or other environmentally safe gaseous materials.
