    Abstract: 1. A process for reducing the drag of aqueous media in turbulent or pulsating flow, which comprises adding to the aqueous medium from 0.01 to 2% by weight of a compound of the formula R1 -K**+ A**- in which K denotes a group of the formula see diagramm : EP0091086,P7,F3 R2 denotes C1 -C3 -alkyl, preferably methyl, A denotes an anion of the following formulae see diagramm : EP0091086,P7,F4 R3 denotes C7 -C10 -alkyl or C7 -C10 -Alkenyl and R1 , if A = R3 COO**- , denotes C16 -alkyl or C16 -alkenyl, if A = thiocyanate, denotes C16 -C26 -alkyl or C16 -C26 -alkenyl and, if A = p-toluenesulfonate, denotes C12 -C26 -alkyl or C12 -C26 -alkenyl, except cetyltrimethylammonium-p-toluenesulfonate.
