Abstract

A method of providing long-lasting disinfection to a hard surface, said method comprising the step of contacting said hard surface with a liquid disinfecting solution having a pH of from 2 to 6 and having low volatility, said liquid disinfecting solution comprising peroxygen bleach and an antimicrobial active selected from the group consisting of thymol, eugenol, menthol, geraniol, vertenone, eucalyptol, pinocarvone, cedrol, anethol, carvacrol, hinokitiol, berberine, ferulic acid, cinnamic acid, methyl salicylic acid, methyl salicylate, terpineol, limonene and mixtures thereof, and an anti-microbial compound having a vapor pressure of less than 0.1 mmHg when measured at 20° C., wherein said anti-microbial compound is selected from the group consisting of citric acid, benzoic acid, benzophenone, and mixtures thereof.

Claims

1. A method of providing long-lasting disinfection to a hard surface, said method comprising the step of contacting said hard surface with a liquid disinfecting solution having a pH of from 2 to 6 and having low volatility, said liquid disinfecting solution comprising peroxygen bleach and an antimicrobial active selected from the group consisting of thymol, eugenol, menthol, geraniol, verbenone, eucalyptol, pinocarvone, cedrol, anethol, carvacrol, hinokitiol, berberine, ferulic acid, cinnamic acid, methyl salicylic acid, methyl salicylate, limonene and mixtures thereof, and an anti-microbial compound having a vapor pressure of less than 0.1 mmHg when measured at 20°

C., wherein said anti-microbial compound is selected from the group consisting of citric acid, benzoic acid, benzophenone, and mixtures thereof.

2. The method of claim 1 wherein said disinfecting solution further comprises an additional ingredient selected from the group consisting of additional disinfecting material, surfactant, chelating agent, radical scavenger, pH buffer, and mixtures thereof.

3. The method of claim 2 wherein said additional disinfecting material is selected from the group consisting of quaternary ammonium compounds, phenolic compounds, glutaraldehyde, formaldehyde, glyoxal, ethyl paraben, propyl paraben, methyl paraben, and mixtures thereof.

4. The method of claim 1 wherein said anti-microbial active, is thymol.

5. The method of claim 1 wherein said liquid disinfecting solution comprises from about 0.003% to about 10% by weight of said anti-microbial active.

6. The method of claim 1 wherein said liquid disinfecting solution comprises from about 0.01% to about 8% by weight of said anti-microbial active.
