  • 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: 5931172
    Abstract: Methods of substantially removing a restriction from a drain pipe system include the steps of introducing a cleaning composition containing a non-caustic drain opening active to the pipe system, activating the cleaning composition by adding a sufficient amount of liquid to the drain pipe system while maintaining a flow-through state through the pipe system, allowing the drain opening active to remain in contact with the restriction for a sufficient time to substantially degrade the restriction, and rinsing the drain opening active from the pipe system. The water flow rate through the pipe system is improved by at least 0.7 liters/minute after 16 hours of the drain opening active contacting the restriction. These methods are effective for both clogged and slow-running drains.

  • Patent number: 5721203
    Abstract: A triphase drain cleaner with hydrocarbon solvent and antifoam drain pipe coating. The triphase drain cleaner consists of a lower sulfuric acid base, an intermediate base consisting of a hydrocarbon solvent, and a top layer consisting of an antifoam slip/release agent. The lower base consists of at least 20 per cent sulfuric acid solution, with the middle base consisting of a hydrocarbon solvent capable of cleaning side walls of the drain pipe, while the upper section consists of an antifoam slip/release agent. The cleaning composition attacks drain blockage consisting of organic and inorganic matter and the foam typically associated with the composition's attack on the blockage. With the elimination of the unwanted foam by the antifoam, slip/release agent, it will also coat the drain side walls to reduce future deposits of matter that leads to drain blockage.
