Patent ID: 8357648

Claim:
A pearlescent unitary dose composition suitable for laundry or hard surface cleaning having a turbidity of greater than 5 and less than 3000 NTU, the composition comprising a water-soluble film encapsulating a liquid treatment composition comprising from 2% to 10% by weight of the composition of water and: (a) from about 0.5% to about 20% by weight of the composition of a pre-crystallized organic pearlescent dispersion premix, which comprises (i) a pearlescent agent having the formula: wherein R 1 is linear or branched C12-C22 alkyl chain; R is linear or branched C2-C4 alkylene group; P is selected from H, C1-C4 alkyl or —COR 2 , R 2 is C4-C22 alkyl; and n=1-3; (ii) a surfactant selected from the group consisting of linear or branched C12-C14 alkyl sulfate, alkyl ether sulfate, and mixtures thereof; (iii) water and adjuncts selected from the group consisting of buffers, pH modifiers, viscosity modifiers, ionic strength modifiers, fatty alcohols, amphoteric surfactants, and mixtures thereof; (b) carrier; and (c) from about 1% to 5% by weight of the composition of a co-crystallizing agent wherein a weight ratio between the pearlescent agent and co-crystallizing agent ranges from about 3:1 to about 10:1; (d) optionally, a laundry adjunct; wherein the unitary dose composition has a viscosity of from about 1 to about 1000 mPa's at 20s −1 and 21° C.; wherein the pearlescent agent comprises mono- and di-fatty acid ethylene glycol ester having a weight ratio ranging from about 1:2 to about 2:1; and further wherein said co-crystallizing agent is selected from the group consisting of fatty acid having a C16-22 alkyl, alkenyl, alkylaryl or alkoxy moiety; fatty alcohol having a C16-C22 alkyl, alkenyl, alkylaryl or alkoxy moiety; and mixtures thereof.
