Abstract
The need for laundry detergent compositions that provide improved deposition of perfume ingredients onto fabrics comprising synthetic fibres, and especially those perfume ingredients that typically do not readily deposit onto synthetic fibres, is met by incorporating a vinylpyrrolidone polymer and specific perfume ingredients into a laundry detergent composition.
Claims21
A liquid laundry detergent composition comprising a surfactant system, pyrrolidone 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 at a level of from about 1.4% to about 52% by weight of the liquid laundry detergent composition;
- wherein the vinylpyrrolidone polymer is selected from the group consisting of:
- polyvinylpyrrolidone (PVP), copolymers of vinylpyrrolidone and vinylimidazole (PVP/PVI), copolymers of vinylpyrrolidone and vinylacetate (PVP/VA), and mixtures thereof;
- and
- wherein the perfume comprises hydrophobic perfume ingredients having a Log P of at least 2.5, wherein the hydrophobic perfume ingredients comprise:
- linalool, ionone beta, lilial, citronellol, citronellyl nitrile, alpha pinene, ethyl safranate, linalyl propionate, allyl amyl glycolate, helvetolide, laevo carvone, phenyl ethyl dimethyl carbinol, or mixtures thereof.
The laundry detergent composition according to 3, 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.
The laundry detergent composition according to any preceding claim, wherein the composition comprises free perfume at a level of from about 0.1% to about 5.0% by weight of the composition.
A method of cleaning laundry using a laundry detergent composition comprising a pyrrolidone polymer for improving the deposition of perfume raw materials onto fabrics comprising synthetic fibres.
