Abstract
The need for laundry detergent compositions that provide improved deposition of hydrophilic perfume ingredients onto fabrics comprising cotton fibres, and especially those perfume ingredients that deposit less readily onto cotton fibres, is met by incorporating certain cationic polymers and specific perfume ingredients into a laundry detergent composition.
Claims14
A liquid laundry detergent composition comprising a surfactant system, cationic polymer and a non-encapsulated perfume,
- wherein the surfactant system comprises surfactant at a level of from about 1.0 wt % to about 70 wt % of the composition, wherein the surfactant system comprises anionic surfactant selected from the group consisting of:
- sulfate surfactant, sulphonate surfactant and mixtures thereof, at a level of from about 1.4% to about 52% by weight of the liquid laundry detergent composition;
- wherein the cationic polymer comprises copolymer of diallyldimethylammonium chloride and acrylic acid;
- and
- wherein the non-encapsulated perfume comprises hydrophilic perfume ingredients having a log P of less than about 3.0, wherein the hydrophilic perfume ingredients comprise:
- allyl amyl glycolate, anisic aldehyde, benzyl acetate, ethyl methyl phenyl glycidate, isoamyl butyrate, laevo carvone, methyl salicylate, para cresyl methyl ether, phenyl ethyl dimethyl carbinol, or a mixture thereof.
The laundry detergent composition according to 1, wherein the anionic surfactant comprises alkyl sulphate surfactant, wherein the alkyl sulphate surfactant has an average degree of ethoxylation of from about 0.5 to about 8.0.
