Microcapsules

摘要

Microcapsule for use in a liquid detergent composition, the microcapsule having a core and a polymeric polyanion-polycation complex shell wherein the polyanion component is capable of gelling in the presence of calcium and has a storage modulus when gelled with 0.05 moles/litre 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. The invention also relates to a process for making the microcapsules, liquid detergents comprising the microcapsules and cleaning methods using the liquid detergents.
