Abstract

<B>"MICROCáPSULAS UMECTáVEIS TENDO NúCLEOS REVESTIDOS DE POLìMERO HIDROFóBICO"<D>. A presente invenção se refere a microcápsulas umectáveis tendo núcleos revestidos de polímeros hidrofóbicos e a um processo para sua preparação. Em particular, as microcápsulas com revestimentos de polímero hidrofóbico são umectáveis, de modo que são suspensas em meio aquoso. As microcápsulas umectáveis podem ser preparadas mediante aplicação de polímero hidrofóbico sobre uma droga que contém um núcleo, mediante separação de fase de um solvente para proporcionar microcápsulas, opcionalmente lavando as ditas microcápsulas com um solvente, em que as ditas microcápsulas são substancialmente insolúveis e secas, caracterizado em que (a): um ou mais tensoativos são incorporados no solvente na etapa de separação de fase e/ou (b): um ou mais tensoativos são incorporados no solvente usado para lavar as microcápsulas e/ou (c): a microcápsula é revestida com um ou mais tensoativos opcionalmente na presença de um solvente.
