Abstract
Peroxyhydroxycarboxylic acid forming compositions and methods for forming peroxyhydroxycarboxylic acids, preferably in situ, using the peroxyhydroxycarboxylic acid forming compositions are disclosed. Methods of using the peroxyhydroxycarboxylic acids, including for treating a surface or a target in need of antimicrobial or sanitizing treatment are also disclosed. Particular applications of using odor-free, low volatility peroxyhydroxycarboxylic acid sanitizers for direct food contact are disclosed.
Claims20
A peroxyhydroxycarboxylic acid forming composition comprising:
- a) a first reagent that comprises a lactone of an alphahydroxycarboxylic acid, and
- b) a second reagent that comprises an alkalinity source,
- c) a third reagent that comprises hydrogen peroxide;
- and
- d) optionally water or a solvent if the first, second and/or third reagents are powders;
- wherein said reagents are provided as powders and/or liquids, and wherein the powder reagents are combined into a premix and the liquid reagents are kept separately from the powder reagents prior to contacting to generate the peroxyhydroxycarboxylic acid;
- and
- wherein the combination of the reagents react to form a liquid that comprises the peroxyhydroxycarboxylic acid and has a pH below about 7 within about 5 minutes after the contact between said reagent.
