Abstract

The process comprises spraying onto previously produced peroxycarboxylic acid granules, while agitating, an aqueous solution or dispersion of a polymeric carboxylic acid which is soluble in aqueous alkaline medium, and drying. The granules coated in this way have high resistance to abrasion and, mixed with other substances, low levels of chemical interactions.
