Abstract: Commercial solutions of noncorrosive and time-stable carboxylic peracids, particularly peracetic acid, contain an acid of oxidizing nature, such as nitric acid, present in a weight percentage at least equal to that of the carboxylic peracid. Such solutions, diluted with ordinary water, are useful for the sterilization and microbiological disinfection of asceptic enclosures, and of equipment of the food industry, particularly the milk industry, with reduced risk of corrosion to the equipment.
