A composition, which 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;
• R2 is OH;
• 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, and
• wherein said first stabilizing agent has a concentration of at least about 0.005 wt-%;
• or a compound having the following Formula (IB):
• wherein

• R6 is hydrogen, (C1-C6)alkyl, (C2-C6)alkenyl or (C2-C6)alkynyl;
• or a salt thereof, and
• wherein said second stabilizing agent has a concentration of at least about 0.1 wt-%;
• and
• wherein said C1-C22 percarboxylic acid has a concentration of about 10 wt-% to about 30 wt-%, said hydrogen peroxide has a concentration of at least about 0.1 wt-%, said C1-C22 percarboxylic acid has a concentration of at least about 3 times of the concentration of said hydrogen peroxide, and said composition has a pH at about 4 or less, and said composition retains at least about 80% of the C1-C22 percarboxylic acid activity after storage of about 30 days at about 50° C.
