Abstract

Broad spectrum disinfecting and microbicidal compositions of biodegradable and environmentally friendly compositions containing esters formed from fatty organic alcohols and fatty carboxylic acids. These compositions display activities against the most resistant microbial forms including bacterial spores. The preparations can be used in health care, food processing, personal care and other industries where the use of harsh oxidizing chemicals is undesirable.

Claims

1. A method of cleaning a surface comprising:

preparing a disinfecting composition that consists of an ester selected from the group consisting of methyl lactate, ethyl lactate, butyl lactate, propyl lactate, hexyl lactate, octyl lactate, and mixtures thereof, wherein the disinfecting composition is food additive safe; and

applying the disinfecting composition to a surface containing microbes, bacteria, and bacterial spores to thereby treat the surface to clean the surface and to reduce the microbial count and wherein the compound has sporicidal activity effective to kill at least 89% of the bacterial spores on the surface.

2. The method as set forth in claim 1, wherein the disinfecting composition consists of a mixture of ethyl lactate and butyl lactate.

3. The method as set forth in claim 1 wherein the surface is the surface of a fruit or vegetable.

4. The method as set forth in claim 1 wherein the surface is skin.
