Abstract
We have found a new and useful process to generate peroxy acid sanitizing and bleaching compositions at the point-of-use, the process comprising introducing hydrogen peroxide and a carboxylic acid into a reactor at about 0.1 to 10 moles of hydrogen peroxide per mole of acid, and contacting the hydrogen peroxide and carboxylic acid in the presence of a sulfonic acid resin and in the substantial abssence of active metal ions which forms an aqueous peroxy acid composition at a concentration from about up to 20 wt %. Using this process, warewashing, laundry sanitizing and bleach, and hard surface sanitizing compositions can be produced.
