摘要： The present invention relates to a process for preparing a particle, the particle comprising: (i) cleaning active; (ii) structurant having a glass transition temperature; and (iii) optionally, plasticizer; wherein the process comprises the step of: (a) contacting the plasticizer, the structurant, and the cleaning active to form a mixture, and forming a particle from the mixture; (b) optionally, removing at least part of the plasticizer from the mixture and/or particle of step (a); wherein the structurant undergoes a glass transformation during step (a) to create an amorphous structure which stabilizes the cleaning active.
