  • Publication number: 20230183607
    Abstract: The disclosure relates a surfactant package for use in hard surface cleaning compositions, preferably floor cleaning compositions which pair an anionic linear alkyl sulfonate surfactant and a nonionic surfactant in a ratio of 1:1 to 9:1. This combination provides for synergistic cleaning of both proteinaceous food soils (red soils) and hydrocarbon-based oily soils (black soils) while also reducing foam produced by the composition. Synergistic nonionic surfactants include EO/PO alcohol alkoxylates or EO/PO fatty alcohol surfactants with a propylene oxide to ethylene oxide to ratio of greater than 1.

  • Publication number: 20220372410
    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: 10655085
    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.
