  • Patent number: 6713441
    Abstract: Disclosed is a toilet bowl cleaner that includes a hypochlorite generator and an effervescent system that produces a foam level approximately one inch above a water line in the toilet. The cleaner may be prepared, stored and packaged in a manner that prevents moisture from initiating premature decomposition of the cleaning components. The toilet bowl cleaner may also include a binder, lubricant, fragrance, and a surfactant mixture. Further, the toilet bowler cleaner may be in the form of a tablet, granules, or a powder. The toilet bowl cleaner may also be coated with a surfactant mixture. Also disclosed is a method for producing the toilet bowl cleaner, including the steps of: combining an effervescent system, a hypochlorite generator, and a binder to form a pre-mix; blending the pre-mix in a blender for approximately 15 to 20 minutes; adding a lubricant to the blended pre-mix; and blending the lubricant with the blended pre-mix for approximately three to four minutes to form a cleaner blend.

  • 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.
