Use as a soil release agent of compounds of formula (I), wherein X is an anion, A is an (m + n) valent radical remaining after the removal of (m + n) hydroxy groups from an aliphatic polyol having p hydroxy groups and an atomic ratio of carbon to oxygen in the range of 1.0 to 3.0 and up to 2 groups per hydroxy group selected from ethylene oxide and propylene oxide, m is 0 or an integer from 1 to p-n, n is an integer from 1 to p-m, and p is an integer of at least 2, B is an alkylene or alkylidene group containing 1 to 4 carbon atoms, R<1>, R<2>, R<3> and R<4> are, independently from each other, straight or branched chain C1-C48 alkyl or alkenyl groups, optionally with substitution by one or more functional groups and/or interruption by at most 10 ethylene oxide and/or propylene oxide groups, or by at most two functional groups selected from (a), (b), (c), (d) and (e) or R<2> and R<3> may form a ring system containing 5 or 6 atoms in the rings, with the proviso that the average compound either has at least one R group having 22-48 carbon atoms, or at least two R groups having 16-20 carbon atoms, or at least three R groups having 10-14 carbon atoms. |
