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.
Claims21
An aqueous surface treating composition comprising one or more alkoxylated sugar esters with:
- a molar ratio of alkoxy units in the alkoxylated sugar ester to hydroxy groups of the starting sugar molecule of, on average, from 1:4 to 3:1,
- a molar ratio of ester groups in the alkoxylated sugar ester to hydroxy groups of the starting sugar molecule of, on average, from 0.25 to 0.70, and
- a HLB value below 8.
Liquid aqueous softening composition comprising an alkoxylated sugar ester with:
- a molar ratio of alkoxy units in the alkoxylated sugar ester to hydroxy groups of the starting sugar of, on average, from 1:4 to 3:1,
- a molar ratio of ester groups in the alkoxylated sugar ester to hydroxy groups of the starting sugar of, on average, from 0.25 to 0.70, and
- a HLB value below 8.
A liquid fabric softening composition comprising a softening effective amount of the alkoxylated sugar ester comprising
- a molar ratio of alkoxy units in the alkoxylated sugar ester to hydroxy groups of the starting sugar of, on average, from 1:4 to 3:1,
- a molar ratio of ester groups in the alkoxylated sugar ester to hydroxy groups of the starting sugar of, on average, from 0.25 to 0.70, and
- a HLB value below 8,
- and at least one performance booster selected from anionic surfactants, cationic surfactants, amphoteric surfactants, non-ionic surfactants and mixtures thereof.
