  • Publication number: 20160264915
    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.

  • Patent number: 9303240
    Abstract: Synergistic combinations of extended chain surfactants and co-surfactants, emulsions or microemulsions and cleaning compositions incorporating the same are provided. In certain embodiments a surfactant system is disclosed which includes extended nonionic surfactants, and a linker surfactant. This system forms stable emulsions or microemulsions with oils, including non-trans fats and fatty acids and these emulsions or microemulsions are stable, irreversible and can be created at low temperature. The cleaning compositions may include the surfactant system alone, a stable emulsion or microemulsion with oil and the surfactant system, a pre-spotter or other pre-treatment or soft surface and hard surface cleaning compositions comprising the surfactant combination.

  • Patent number: 8906839
    Abstract: Solid block alkaline detergent compositions are disclosed comprising a source of alkalinity, and other detergent additives including sequestrants. The solid block detergents of the invention used a mixed inorganic and organic sequestrant composition that successfully softens service water used in manufacturing aqueous detergents from the composition, but also obtains substantially improved organic soil removal on dishware or flatware. The solid block detergents of the invention comprise large masses of the chemical ingredients having a weight of greater than about 500 grams in a solid block product format that is typically dispensed using a spray on water dispenser that creates an aqueous concentrate that is used in a washing machine.

  • Publication number: 20140251919
    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.
