Food processing equipment, food contact surfaces, and non-food contact surfaces are sanitized or disinfected using an acid-anionic surfactant solution that has efficacy in hard water, is non-corrosive, and is stable at elevated temperatures. The sanitizing/disinfecting solution is prepared as a highly concentrated liquid and diluted to end use concentrations prior to application to food processing equipment or food or non-food contact surfaces. Efficacy in hard water is important for sanitizers and disinfectants that are diluted by the end user using potentially hard water. Stability at elevated temperatures is important for long-term storage and transportation. The diluted sanitizing/disinfecting solution exhibits strong antimicrobial activity against gram positive and gram negative bacteria even when diluted in hard water. The sanitizing/disinfecting solution exhibits low toxicity to humans and the environment since it is prepared from low toxicity ingredients that are readily biodegradable.

The invention relates to compositions including a charged oligo-phenylene ethynylene singlet-oxygen sensitizer and an oppositely-charged surfactant, which show an enhanced biocidal activity relative to a comparable concentration of the oligo-phenylene ethynylene without the oppositely-charged surfactant. The enhancement of biocidal activity is observed with an anionic oligo-phenylene ethynylene in the presence of a cationic surfactant such as TTAB, and with a cationic oligo-phenylene ethynylene in the presence of an anionic surfactant such as SDS.

The present invention is directed to antiviral compositions that provide efficacy against non-envelope viruses such as noroviruses. The antiviral compositions comprise an alkyl 2-hydroxycarboxylic acid and an effective amount of a sulfonated surfactant. The composition may be used as a topical on human skin, as a hand sanitizer or as a hard surface cleaning composition.
