With Alkali Metal Compound Patents (Class 252/187.29)
  • Publication number: 20150097140
    Abstract: The invention relates to compositions, methods of use, and methods of manufacture for an intercalated bleach compound and compositions thereof. The intercalated bleach compound has the formula Mx(OCl)y(O)m(OH)n where M is an alkaline earth metal such as magnesium, calcium or mixture thereof. The values of x and y independently equal any number greater than or equal to 1 (e.g., 1, 2, 3, 4, etc.), and m and n independently equal any number greater than or equal to 0 (e.g., 0, 1, 2, 3, 4, etc.), but m and n are not both 0. In addition, the molar ratio of the alkaline earth metal (e.g., magnesium or calcium) to hypochlorite is at least 3:1. In other words, x is ?3y. The compounds exhibit excellent stability, little or no chlorine bleach odor, exhibit excellent pH buffering characteristics, and less reactivity with organic materials as compared to alternative chlorine bleach products.

  • Patent number: 8603392
    Abstract: Corrosion-inhibited hypochlorite compositions and methods of use are disclosed. Corrosion inhibitors including sugar acids and calcium compounds, polyacrylate and calcium compounds, and/or zinc and calcium compounds are used with hypochlorite sources to enhance the longevity and performance of electrochemical cells as well as reducing corrosion of metal in contact with the generated hypochlorite sources. The methods for generation employ a variety of electrochemical cells, beneficially including use of portable electrochemical cell system for production of corrosion-inhibited hypochlorite cleaning solutions.

  • Patent number: 8486879
    Abstract: A solid composition including calcium and/or magnesium hypochlorite, a builder (e.g., one or more of carbonate, bicarbonate, sesquicarbonate), an acid, a water-soluble polymer, at least one anionic surfactant, and optionally, a hydrotrope. The composition does not include any potassium hypochlorite, sodium hypochlorite, lithium hypochlorite, N-halogenated compounds, peroxides, persulfates, hydantoins, isocyanurates, or carboxylic acids that also have hydroxyl, amino, amido, imino, or imido groups. Upon dissolution of the composition in water, the calcium and/or magnesium hypochlorite and acid react to form hypochlorous acid. The use of hypochlorous acid, rather than direct use of an alkaline or alkaline earth hypochlorite results in a composition that is typically acidic rather than basic, and that results in improved cleaning. The composition is particularly suited for cleaning and disinfecting dentures.

  • Patent number: 7435380
    Abstract: A pseudo-plastic or thixotropic carrier having anti-malodorous components dissolved or suspended therein is sprayed on the internal surfaces of an ostomy bag or pouch. The viscoelastic properties of the carrier allow the composition to be conveniently dispensed from a spray bottle into the ostomy bag and retained on the inner walls thereof without being displaced therefrom by incoming waste during use of the ostomy bag. This allows the composition to continue to deodorize the ostomy bag headspace even after waste material begins to fill the bag.
