Abstract (en)

[origin: EP0497337A2] 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.
