Abstract
The invention relates to specific aqueous compositions comprising alkoxylated sugar esters and their use as a softener. The alkoxylated sugar esters are characterised by a molar ratio of alkoxy units to hydroxy groups of the unmodified sugar from 1:4 to 3:1, a molar ratio of ester groups to hydroxy groups of the unmodified sugar from 0.25 to 0.70, and an HLB value below 8, preferably from 1-3. Preferably the alkoxylated sugar esters are combined with performance boosters selected from cationic and non-ionic compounds to increase their softening performance.
