  • Patent number: 11932833
    Abstract: Peroxide treatment compositions for use in laundry capable of providing sanitization through the wash e.g., for use with a detergent, where a peroxide activator is stabilized without the presence of phosphorus-containing compounds (e.g., phosphorus-containing stabilizers), through use of a nonionic surfactant (e.g., alkoxylated alcohol) with a cloud point above 45° C. Use of a single nonionic surfactant, or a surfactant package that may include a small fraction (e.g., less than 0.5%) of sodium lauryl sulfate or another anionic surfactant has been found to be surprisingly effective at stabilizing the peroxide/activator combination, even where water content may be 85% or greater. The composition can have a pH of 5 or less (e.g., 3 to 4). The composition may be free of other anionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, magnesium salts, borates and boric acid, hydroxides, chelating agents, various amine oxides, ethoxylated amines, and the like.

  • Publication number: 20230002703
    Abstract: Treatment compositions for use in laundry capable of providing sanitization through the wash e.g., for use with a detergent, where the compositions include an inorganic zinc salt potentiated by a phenolic solvent, to provide sanitization. The compositions can include an inorganic zinc salt, and a phenolic solvent, e.g., at an acidic pH (e.g., 2 to 5, or 3.5 to 4.5). The composition can include an anionic surfactant (e.g., alkyl sulfates, alkyl ether sulfates, etc.) and/or a nonionic surfactant (e.g., an alkyl polyglucoside). The composition may be free of alkoxylated nonionic surfactants which are not stable in the present compositions, which have high ionic strength (e.g., due to ˜3% of the zinc salt included in the formula). The composition may be free of various other components that would not be stable in such high ionic strength conditions, or otherwise interfere with stability and efficacy of the sanitizing and/or disinfecting laundry composition.
