Stable Microcapsule Compositions

Abstract

Disclosed are stable microcapsule compositions each containing a microcapsule dispersed in an aqueous phase and a stabilizing agent. The microcapsule compositions are stable for at least 4 weeks when storing at 45° C., and the microcapsule composition is considered stable when (i) the composition has a viscosity of 3000 cP or less and (ii) 20% or less water by volume of the composition is separated from the composition. Also disclosed are consumer products having such a stable microcapsule composition.
