  • Patent number: 10035977
    Abstract: Caustic-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, non-caustic source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces. The detergent compositions are used with a sanitizer to employ the caustic-free detergent compositions are particularly suitable for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the caustic-free detergent compositions are also provided.

  • Patent number: 10035975
    Abstract: A cleaning composition including a primarily C12 quaternary functionalized alkyl polyglucoside selected from the group consisting of stearyldimoniumhydroxypropyl laurylglucosides chloride and lauryldimoniumhydroxypropyl cocoglucosides chloride, a water conditioning agent, an acid source, a solvent, and water. In one embodiment, the cleaning composition is substantially free of alkyl phenol ethoxylates. The cleaning composition is capable of removing soils including up to 20% proteins. The cleaning compositions include a biorenewable, environmentally friendly alternative to nonyl phenol ethoxylates and exhibit superior cleaning of food soils.

  • Patent number: 10011809
    Abstract: Caustic-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, non-caustic source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces and enhance protein removal from the treated surfaces. Beneficially the detergent compositions have a concentrate pH less than about 11.5. The detergent compositions are used with a sanitizer to employ the low alkaline detergent compositions are particularly suitable for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the low alkaline detergent compositions are also provided.

  • Patent number: 10005984
    Abstract: The invention involves liquid cleaning compositions that are cocamide DEA free. According to the invention, nonionic surfactants can be used as rheology modifiers in combination with various coupling agents to provide an environmentally friendly alternative for traditional liquid cleaning compositions that rely on cocamide DEA thickening agents.

  • Patent number: 9969959
    Abstract: Industrial 2-in-1 cleaning compositions providing both detergency and rinseability in a single cleaning composition are disclosed. Alkali metal carbonate-based cleaning compositions and methods of both making and using the same provide user-friendly, solid, detergent compositions without the need for using a separate rinse aid composition. The compositions and methods are particularly well suited for use in industrial cleaning using alkali metal carbonate compositions that beneficially provide cleaning and rinseability in the rinse cycle.

  • Patent number: 9896364
    Abstract: The present invention relates to methods, apparatuses, and systems for treating water. The methods, apparatuses and systems reduce scaling associated with solubilized water hardness using a sequence of water treatment agents, including an inlet, one or more treatment reservoirs containing a first treatment agent that is an exhausted ionic resin that is incapable of performing ion exchange and a second treatment agent consisting of a metal oxide and/or hydroxide compound, an outlet, and a treated water delivery line.
