alkyl, alkenyl or hydroxyalkyl group(s) being attached to an ester or ether group. Preferably the compound has two or more ester and/or ether groups. A fabric softening composition comprises from 1 to 80 wt % of the softening compound, based on the total weight of the composition. A method for forming such compounds comprises reacting a cyclic polyol or a reduced saccharide with a fatty acid and a halogen alkyl acid chloride to form an, at least partly, esterified cyclic polyol or reduced saccharide and then quaternising the esterified compound so as to form a CPED or RSED comprising a quaternary ammonium group.
