Fabric softening composition

摘要

Fabric conditioning compositions having a pH of less than 5 and comprising a fabric softening compound of general formula I and exhibiting good hydrolytic stability. (I) (R<1>-CO.-O-)mA(-O-CO.-B-N<+> R<2>R<3>R<4>)n NX<-> wherein X is Br,mesylate or methylsulphate A is an m+n valent radical remaining after the removal of m+n OH groups from an aliphatic polyol having p OH groups and a C:O ratio of 1.0 to 3.0 m, n + p are integers from 1 to p-n, 1 to p-m and at least 2 respectively. B is a C1-C11 alkylene or alkylidene group R<1> is a C10-C48 alkyl or alkenyl group, at least one being C22-C48 or at least 2 being C16-C20 or at least 3 being C10-C14. R<2>-R<4> are independently C1-C4 alkyl or alkenyl groups optionally substituted/interupted by ethylene oxide or propylene oxide groups or other CO or CNO containing groups, or R<2> and R<3> form a 5-6 atom ring.
