Abstract: A process for the preparation of ureidoperoxycarboxylic acids of the formula A[NHCONHBCOOOH]x, in which x is the number 1 or 2, A, if x is 1, is hydrogen, C1-C20-alkyl, aryl, preferably phenyl, or haloaryl, preferably chlorophenyl, or if x is 2, is C1-C20-alkylene or arylene, preferably phenylene, B is a group of the formula in which n is a number from 1 to 20, m is the number 0, 1 or 2, R1 is C1-C20-alkyl and R2 is in each case hydrogen or C1-C20-alkyl, which comprises dissolving carbamoyllactams of the formula in which x, A and B have the abovementioned meanings, in a one- to six-fold, preferably a one- to three-fold, amount by weight of a strong catalyst acid, by then adding water in a one- to ten-fold molar excess, relative to the carbamoyllactam, to the solution of the carbamoyllactam in the catalyst acid and by heating the reaction mixture to form the ureidocarboxylic acid, by then adding to the reaction mixture an aqueous hydrogen peroxide solution in a one- to ten-fold, preferably a two- to four fold, molar excess per oxidizable carboxyl group of the ureidocarboxylic acid formed in the preceding reaction step, and by then precipitating the resulting ureidoperoxycarboxylic acid from the reaction mixture. These compounds are suitable as bleaches, oxidants and disinfectants.

Abstract: Storage-stable aqueous suspensions of organic peracids containing 1 to 50 % by weight of a surfactant mixture consisting of 1 to 4 parts by weight of a C8-C22-fatty alcohol, oxyethylated with 1 to 5 units of ethylene oxide, and 4 to 1 parts by weight of a C8-C22-fatty alcohol, oxyethylated with 6 to 25 units of ethylene oxide, and optionally in addition other conventional components. It is possible owing to the use of two different surfactants to adjust very different viscosity levels in these suspensions, from low viscosity to pasty formulations.
