Abstract
The present invention relates to cleaning compositions containing one or more linear or branched C6-C18 alkyl sulphate surfactants with a specific chain length distribution in combination with a cationic polymer containing one or more cationic structural unit with a cationic charge density ranging from 0.05 to 10 milliequivalents/g. Such cleaning compositions exhibit surprising and unexpected improvement in the sudsing profiles and are particularly suitable for use in hand-washing fabrics.
Claims23
A cleaning composition comprising:
- (a) one or more linear or branched C6-C18 alkyl sulphate (“AS”) surfactants, which comprise from 80% to 100% by weight of one or more linear or branched C6-C14 AS surfactants;
- and
- (b) one or more cationic polymers comprising a cationic structural unit and having a cationic charge density ranging from 0.05 to 10 milliequivalents/g.
A liquid laundry detergent composition comprising:
- (a) from 0.5% to 5% by weight of a linear C12 AS surfactant;
- (b) from 0.1% to 2% by weight of a linear C14 AS surfactant;
- (c) from 0.05% to 1% by weight of a linear C16 AS surfactant;
- (d) from 0.1% to 2% by weight of a cationic polymer which is a copolymer or terpolymer containing a first cationic structural unit derived from DADMAC, MAPTAC, APTAC or QVi, a second nonionic structural unit derived from AAm, and optionally a third nonionic structural unit derived from VP;
- (e) from 5% to 20% by weight of C10-C20 linear alkyl benzene sulphonates;
- and
