Abstract
Patente de Invenção: <B>"MéTODO PARA MICROENCAPSULAçãO DE UMA SUBSTANCIA SóLIDA"<D>. A presente invenção fornece um método de microencapsulação de uma substância sólida e a composição microencapsulada obtida do referido método de: (i) preparar uma fase de dispersão compreendendo (a) uma solução contendo uma substância que forma uma camada média e (b) uma substância sólida que é insolúvel ou difícil de dissolver na referida solução (ii) obter uma substância sólida que tem uma camada feita de substância que forma a camada média pela separação de fase da substância que forma a camada média da solução e (iii) reagir um monómero que é polimerizável pela condensação na presença da substância sólida que tem uma camada feita da substância que forma a camada média. O método acima pode eficientemente microencapsular ingredientes farmacêuticos ativos, ingredientes pesticidas, ingredientes ativos de aroma e assim por diante, que são substâncias sólidas e proporcionam uma composição microencapsulada eficaz de substâncias sólidas.
