  • Patent number: 8044008
    Abstract: A novel and safe composition has been discovered that is effective for cleaning dental appliances (e.g. removable braces, retainers, dentures, etc.). This composition bleaches, disinfects, and deodorizes the appliance, while removing plaque that has accumulated on the appliance during wear. The composition comprises a chloramine bleaching agent that liberates hypochlorous acid upon contact with water, a surfactant, a water-soluble carboxylic acid and an alkaline base to produce effervescence and regulate pH, a sequestering agent for alkaline earth metal ions, a drying agent, and an indicator dye that signifies the end of the cleansing process. In a preferred method of using this invention, the premixed components are added to water, and the dental appliance is submerged in the resulting effervescent solution until a color change indicates that cleaning is complete. This invention provides a safe, effective, and convenient method for cleansing and disinfecting dental appliances.

  • Patent number: 8003586
    Abstract: A cleaning solution for automatic biochemical analyzers includes: at least one anionic surfactant, at least one nonionic surfactant, an alkali metal hydroxide, an alkali metal citrate, and a buffering agent stabilizing the pH value above 13.0. In some embodiments, the cleaning solution provides low residual rate of proteins, low residual rate of lipids, desirable within-batch repeatability in clinical testing, low level of cross-contamination, and low level of reactant deposit after cleaning, without affecting test results of the biochemical analyzer. In some embodiments, the cleaning solution has no corrosive effects on the liquid path and reaction cup of the analyzer. The ingredients of the cleaning solution may also be biodegradable.
