  • Publication number: 20200277547
    Abstract: Improved liquid detergent concentrate compositions which are phosphorus free and utilize an acrylic copolymer to provide improved stability while maintaining viscosity are provided. Methods of using the same to wash textiles are also provided. The improved liquid detergent composition may be provided in the form of the concentrated emulsion or a use solution; and where the concentrated emulsion can be a water-in-oil emulsion or oil-in-water emulsion dependent on the amounts of water and oil in the emulsion.

  • Patent number: 10377979
    Abstract: The invention provides methods of cleaning including the use of a soil release polymer. In some embodiments, the soil release polymer can be included in a neutral to low alkalinity prewash or main wash that is substantially free of hydroxide-based alkalinity. In some embodiments, the soil release polymer can be included in a neutral to low alkalinity prewash that is substantially free of hydroxide-based alkalinity, followed by an alkaline main wash with any alkalinity source.
