Patents by Inventor David Dotzauer

David Dotzauer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20260015554
    Abstract: High active, high caustic liquid laundry detergent compositions which provide excellent stability are disclosed, including methods of making and using the same. The compositions generally comprise a source of alkalinity, a rheology modifier, one or more sequestering agents, one or more low mole ethoxylated nonionic surfactants, and an alkylpolysaccharide surfactant. The liquid detergent emulsions, provided as a concentrate, water-in-oil use solution emulsion, or oil-in-water use solution emulsion beneficially demonstrate improved stability even under high pH and high temperature conditions.

  • Publication number: 20250388837
    Abstract: Detergent compositions and methods of preparing and using the detergent compositions are disclosed. The detergent compositions comprise a polymer system comprising at least one polycarboxylic acid polymer, copolymer, or terpolymer, an alkalinity source comprising an alkali metal carbonate, a nonionic surfactant and water. The detergent compositions are suitable at alkaline pH and reduce or prevent scale formation, improve soil dispersion, and provide effective detergency.

  • Patent number: 12435298
    Abstract: The present invention relates to a detergent composition comprising alkali metal carbonate, a chelant selected from the group consisting of MGDA, alkali metal tripolyphosphate, GLDA, and mixtures thereof, alkali metal percarbonate, and a peroxidation catalyst, wherein the molar ratio of chelant to alkali metal percarbonate is in the range of 1.8 to 3.4. The detergent composition is particularly suited for the removal of tea and coffee stains.

  • Publication number: 20250197624
    Abstract: Stable solid compositions employing a water conditioning agent, including hygroscopic species or non-hygroscopic species. In particular, solid compositions combining an ionic surfactant or an amphoteric surfactant with a water conditioning agent, preferably a polyacrylate water conditioning agent, are disclosed. The ionic surfactant or amphoteric surfactant beneficially stabilize the polymer and/or chelant water conditioning agent, preferably a polyacrylate water conditioning agent, to permit formulation into a solid composition and provide stability under harsh conditions, including humid environments. Applications of using the stable solid compositions are also disclosed.

  • Publication number: 20250109361
    Abstract: The invention includes ware detergent compositions which provides superior cleaning and removal of oily and fatty soils, without the production of excessive foam. According to the invention applicants have discovered that use of a quaternary cationic surfactant in combination with a nonionic low foaming surfactant can provide oily soil removal from ware that is superior to traditional warewash detergent formulations. Compositions for alkaline, preferably solid, warewash detergents are disclosed, as well as their use in dish machines and methods of manufacture.
