Abstract
The invention discloses multifunctional textile auxiliary formulations comprising PA1 (a) 10 to 60% by weight of one or more than one nonionic surfactant of formula (1), PA1 (b) 10 to 60% by weight of the reaction product of one or more than one nonionic surfactant of formula (2) and of an ethylenically unsaturated sulfonic or carboxylic acid or an anhydride thereof, PA1 (c) 4 to 20% by weight of a hydrotropic agent, PA1 (d) 0 to 20% by weight of a nonionic surfactant of formula (3), PA1 (e) 0 to 8% by weight of a magnesium salt of an organic carboxylic acid, PA1 (f) 0 to 30% by weight of a chelating agent or sequestrant, PA1 (g) 0 to 10% by weight of a diol or polyol, and PA1 (h) 0 to 60% of water, with the proviso that the textile auxiliary formulations must contain one of components (e) to (g). The novel textile auxiliary formulations are distinguished by their low foaming properties, their storage-stability, their peroxide-stabilizing properties, their good emulsifiability and their good rewettability. In addition, the formulations are readily biogradable.
