Abstract

PARTÍCULAS SàLIDAS PROVENIENTES DA DESESTABILIZAÇçO CONTROLADA DE MICROEMULSÕES. A presente invenção refere-se a um processo para fazer uma substância particulada. O processo compreende fornecer uma emulsão, op- cionalmente uma microemulsão, compreendendo gotículas dispersadas em uma fase líquida contínua. Pelo menos algumas das gotículas da emulsão compreendem núcleos. As gotículas são então pelo menos em parte desestabilizadas para a formar a substância particulada.
