  • Publication number: 20210032575
    Abstract: Phosphorus-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, 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 phosphorus-free detergent compositions for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the phosphorus-free detergent compositions are also provided.

  • Publication number: 20200347320
    Abstract: The present invention is directed to rinse aid compositions and methods for making and using the rinse aid compositions. The compositions of the invention include a sheeting agent, a defoaming agent, and an association disruption agent. The rinse aid compositions of the present invention result in a faster draining/drying time on most substrates compared to conventional rinse aids. The rinse aid compositions of the present invention are especially suitable for use on plastic substrates.

  • Publication number: 20190389741
    Abstract: The present invention provides improved methods for purifying and/or removing oily particles, and/or contaminants suspended or dissolved in water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing an oil phase from an oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is combined with surfactant in appropriate ratios to facilitate oil removal for water purification in any of a number of commercial, environmental and industrial applications.
