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.
