  • Patent number: 12203050
    Abstract: Cleaning systems employing detergent compositions in combination with builders comprising alkalinity and chelants are provided. The detergent compositions include amine oxide surfactant and alcohol ethoxylate surfactant blends having a mixture of chain lengths and branching provided. The detergent compositions are particularly efficacious for flexible cleaning systems for cosmetic and other soils as they provide the benefit of separate dosing of surfactants in the detergent from alkalinity sources in a builder composition. Methods of using the detergent compositions and/or the cleaning systems are provided.

  • Patent number: 12152193
    Abstract: Compositions comprising a neutral surfactant or a reaction product thereof and a reaction product of a saccharide polymer and a fatty acid may be obtained in the presence of water and a hydroxide base (optionally in the presence of the neutral surfactant), the saccharide polymer comprising a dextran, a dextrin compound, or any combination thereof. The reaction product of the saccharide polymer and the fatty acid may be present at a concentration effective to lower surface tension of the neutral surfactant. Depending on the fatty acid identity, among other factors, the compositions may promote emulsification or de-emulsification. In addition, the compositions may promote foam formation under appropriate conditions. Treatment fluids comprising the compositions, including foamed treatment fluids, may be introduced into a subterranean formation to perform a treatment operation in which fluid emulsification or de-emulsification may occur.
