    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.

    Abstract: The present invention is for an acidic cleaning composition which has excellent cleaning performance, low toxicity and good antimicrobial efficacy. The inventive acidic cleaning compositions are capable of sanitizing or disinfecting a variety of hard surfaces. The inventive acidic cleaning compositions can take a variety of forms, such as: disinfecting wipes, all-purpose disinfecting sprays, kitchen cleaners, bathroom cleaners, toilet cleaners, etc. The compositions may meet EPA DfE requirements, EPA category III or IV requirements, and/or be safe for use on food contact surfaces without rinsing. The compositions may include citric acid, an anionic surfactant, a non-volatile glycol solvent, a fatty acid, and water. The compositions may be free of other sanitizing acids, quaternary ammonium compounds, biguanides, peroxides, hypohalites, etc., and have a pH of less than 2.5. The composition may provide sanitization or disinfection against a target microbe within 5 minutes or less, or 4 minutes or less.
