Alkaline Earth Metal Hypochlorite Patents (Class 252/187.27)
  • Patent number: 9464262
    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: 7695631
    Abstract: A method and composition for reducing chemical oxygen demand is presented. The composition includes a persulfate donor and a transition metal catalyst in contact with the persulfate donor. When the composition is contacted by water, the transition metal catalyst reacts with persulfate and reduces the persulfate concentration in the water. The composition allows the use of persulfate, which is known to cause irritation to users of aquatic facilities (e.g., pools, spas) that come in contact with it. As the persulfate concentration is reduced rapidly in the water by the catalyzed reaction, the persulfate-containing cleaning product may even be used while the aquatic facilities are being used. Optionally, a free halogen donor may be incorporated into the composition. The composition may be in the form of powder, granules (coated or uncoated), or agglomerate.
