Abstract:
A method for enhancing bleaching efficacy for treatment of articles, including for example laundry is disclosed. Methods for sanitizing and/or disinfecting and bleaching laundry and other articles is provided by washing the articles with a peroxyformic acid composition at a first pH for effective antimicrobial efficacy, thereafter applying an alkaline source to increase the pH for addition of a bleaching activator and/or catalyst for the bleaching agent at a second pH, and lastly draining the remaining components of the peroxyformic acid composition, and the bleaching agent and bleach activator/catalyst from the articles. The methods can be provided as part of a laundry cleaning operation and can be utilized in industrial and commercial applications.

Claim (Index 1):
A method of antimicrobial sanitizing and/or disinfecting treatment and bleaching of laundry, the method comprising:\n a. washing the laundry with a peroxyformic acid composition at a pH range from about 4 to about 7 in a laundry washing machine for antimicrobial efficacy on the laundry, wherein the peroxyformic acid composition comprises peroxyformic acid, formic acid and hydrogen peroxide; thereafter b. adding an alkalinity source to the washing machine to increase the pH range to at least above 9 in the laundry washing machine; thereafter c. adding a bleach activator and/or catalyst composition to boost the bleaching efficacy of the peroxyformic acid composition on the laundry in the laundry washing machine; and d. optionally applying a detergent use solution to remove soil from the laundry at any point in the method of sanitizing and/or disinfecting and bleaching of the laundry; e. draining the peroxyformic acid composition, the detergent use solution and the bleach activator and/or catalyst composition from the laundry, wherein (i) the peroxyformic acid composition has a ratio of peroxyformic acid to hydrogen\n peroxide of 1:1 or greater hydrogen peroxide, and/or (ii) the method comprises an additional step of adding additional hydrogen peroxide to the wash of the laundry washing machine to increase the bleaching efficacy of the peroxyformic acid composition.
