Title
(EN) STABLE MICROCAPSULE COMPOSITIONS
(FR) COMPOSITIONS DE MICROCAPSULES STABLES
Abstract
(EN)
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.

L'invention concerne des compositions de microcapsules stables contenant chacune une microcapsule dispersée dans une phase aqueuse et un agent stabilisant. Les compositions de microcapsules sont stables pendant au moins 4 semaines lors du stockage à 45 °C, et la composition de microcapsules est considérée comme stable lorsque (i) la composition a une viscosité de 3000 cP ou moins et (ii) 20 % ou moins d'eau en volume de la composition est séparé de la composition. L'invention concerne également des produits de consommation ayant une composition de microcapsule stable.
