OG exemplary drawing
 
1. A peroxyformic acid composition comprising:
a) a first reagent that comprises a polyhydric alcohol ester of formic acid;
b) a second reagent that comprises hydrogen peroxide or an inorganic peroxo compound that generates hydrogen peroxide when contacted with an aqueous solution; and
c) a formed liquid comprising peroxyformic acid;
wherein the first reagent and the second reagent are kept separately prior to use;
wherein the formed liquid comprising peroxyformic acid is generated by contacting the first reagent and the second reagent; and
wherein the pH of the formed liquid becomes about 8 or lower within about 1 minute after the contacting between the first reagent and the second reagent.
