Abstract
A liquid laundry detergent composition that includes a liquid phase, a lamellar liquid crystal phase, and a particulate phase, where the lamellar liquid phase and particulate phase are dispersed within the liquid phase.
Claims20
A liquid laundry detergent composition comprising:
- a. a liquid phase;
- b. a lamellar liquid crystal phase;
- c. a particulate phase;
- wherein the lamellar liquid phase and particulate phase are dispersed within the liquid phase and wherein the particulate phase is defined as the solid obtained when the liquid laundry detergent composition is centrifuged at about 1200 G for about 10 mins and wherein the term ‘lamellar liquid crystal’ means the system being in a state where the surfactant molecules are organised in stacks of bilayers of surfactant in the melted state separated by thin layers of solvent;
- and
- wherein the liquid phase comprises between about 5% and about 40% by weight of the liquid of an alcohol selected from the group comprising ethylene glycol, 1,3 propanediol, 1,2 propanediol, tetramethylene glycol, pentamethylene glycol, hexamethylene glycol, 2,3-butane diol, 1,3 butanediol, diethylene glycol, triethylene glycol, polyethylene glycol, glycerol formal, dipropylene glycol, polypropylene glycol, dipropylene glycol n-butyl ether, and mixtures thereof;
- and
- wherein the composition has an equilibrium relative humidity of less than about 65% at about 20° C. as measured via the composition eRH test described herein;
- and
- wherein the composition comprises less than about 5% by weight of the composition of a hydroxyl-containing amine compound,
- wherein the composition comprises between about 5% and about 35%, by weight of the composition of the lamellar liquid crystal phase,
- wherein the composition comprises between about 25% and about 55% by weight of the composition of the particulate phase.
