Patent ID: 7960330

Claim:
A liquid detergent composition comprising: a) a surfactant; b) from about 0.01% to about 30% by weight of a chelant/builder; c) a microcapsule for use in a liquid detergent composition, the microcapsule having a core and a polymeric polyanion-polycation complex shell having a polycation component selected from the group consisting of chitosan, quaternarised chitosan, and mixtures thereof and having a polyanion component, wherein the polyanion component is alginate having a ratio of mannuronic to guluronic units (M:G ratio) of at least about 1.5:1 to about 4:1 and a fraction of guluronic/guluronic (GG) blocks of less than about 0.5, wherein the polyanion component is capable of gelling in the presence of calcium and said polyanion component has a storage modulus when gelled with 0.05 moles/liter of calcium of less than about 150 Pa at an angular frequency of about 0.5 rad/s and a polyanion concentration of about 3.8% by weight at 25° C.; wherein said microcapsule dissolves/disintegrates during a wash process.
