摘要： A method for assessing the release performance of microcapsules comprising at least one volatile ingredient, the method comprising the steps of:



a. applying a plurality of said microcapsules to an underlying surface;
b. applying a kinetic frictional shear stress τ through a contact surface of a probe under a predefined load, a predefined contact surface area and a predefined shear rate to said plurality of microcapsules; and
c. measuring the amount of the at least one volatile ingredient released per second from said microcapsules under said kinetic frictional shear stress τ.
