23443-436 Flame resistant aqueous hydraulic fluids which contain 5 to 30% by weight of alkylpolyglycoside of the formula R-O-Zn wherein R represents an alkyl radical having 8 to 20 carbon atoms and Zn represents an oligoglycoside radical having, on the adverage, 1 to 10 hexose or pentose units or mixtures thereof. The fluids further contain up to 20% by weight of surfactant additives and up to 10% by weight of other customary additives. The novel fluids are ecologically safe and have good lubricating properties at low concentrations of active ingredient.
