Abstract
A quaternary ammonium composition is claimed which essentially consists of wherein R1 is C8-C22-alkyl, C8-C22-alkenyl, C8-C22-alkylamidopropyl, C8-C22-alkenyl-amidopropyl, C8-C22-alkyl/alkenyl(poly)alkoxyalkyl, C8-C22-alkanoylethyl or C8-C22-alkenoylethyl, R2, R3 and R4 are C1—C22-alkyl, C2-C22-alkenyl or a group of the formula -A-(OA)n-OH, A is —C2H4— and/or —C3H6—, n is a number from 0 to 20 and X is an anion, b) water and c) a non-ionic solvent of the general formula R—O-(AO)nH, where R is hydrogen, alkyl or alkenyl containing 8 to 22 carbon atoms, or phenyl, A is C2H4 and/or C3H6 and n is a number from 0 to 20, which composition is characterized in that it contains less than 20% by weight of water.
