Claim 0:
1. A method for non-refrigerated transport or storage of a peroxycarboxylic acid composition, comprising:
stabilizing the peroxycarboxylic acid composition with a first and second stabilizing agent that increases self-accelerating decomposition temperature (SADT) of the peroxycarboxylic acid composition to form a stabilized peroxycarboxylic acid composition having a SADT greater than about 45° C., wherein the stabilized peroxycarboxylic acid composition comprises:
1) a C1-C22 carboxylic acid;
2) a C1-C22 percarboxylic acid;
3) hydrogen peroxide;
4) a first stabilizing agent, which is a picolinic acid or a compound having the following Formula (IA):, wherein
R1 is OH or —NR1aR1b, wherein R1a and R1b are independently hydrogen or (C1-C6)alkyl;
R2 is OH or —NR2aR2b, wherein R2a and R2b are independently hydrogen or (C1-C6)alkyl;
each R3 is independently (C1-C6)alkyl, (C2-C6)alkenyl or (C2-C6)alkynyl; and
n is a number from zero to 3;
or a salt thereof;
or a compound having the following Formula (IB):, wherein
R1 is OH or —NR1aR1b, wherein R1a and R1b are independently hydrogen or (C1-C6)alkyl;
R2 is OH or —NR2aR2b, wherein R2a and R2b are independently hydrogen or (C1-C6)alkyl;
each R3 is independently (C1-C6)alkyl, (C2-C6)alkenyl or (C2-C6)alkynyl; and
n is a number from zero to 3;
or a salt thereof;
5) a second stabilizing agent, which is a compound having the following Formula (IIA):, wherein
R1, R2, R3, and R4 are independently hydrogen, (C1-C6)alkyl, (C2-C6)alkenyl or (C2-C6)alkynyl, or C6-20 aryl;
R5 is (C1-C6)alkyl, (C2-C6)alkenyl or (C2-C6)alkynyl; and
R6 is hydrogen, (C1-C6)alkyl, (C2-C6)alkenyl or (C2-C6)alkynyl;
or a compound having the following Formula (IIB):, wherein
R1, R2, and R3 are independently hydrogen, (C1-C6)alkyl, (C2-C6)alkenyl or (C2-C6)alkynyl, or C6-20 aryl;
or a salt thereof; and

wherein
said hydrogen peroxide has a concentration of at least about 0.1 wt-%, the C1-C22 percarboxylic acid has a concentration of at least about 2 times of the concentration of said hydrogen peroxide, and said stabilized peroxycarboxylic acid composition has a pH at about 4 or less; and
transporting or storing the stabilized peroxycarboxylic acid composition without refrigeration below 45° C.
