Abstract

Patente de Invenção: <B>"MéTODO PARA PREPARAR UM MATERIAL GRANULAR NANOPOROSO E UMA COMPOSIçãO DETERGENTE"<D>. São revelados um processo para produzir um material de partida sob uma forma granular e em um estado anídrico nanoporoso, um processo para melhorar as características de solubilidade em água e de liberação controlada de um material detergente, e uma composição detergente. Em um aspecto, um processo para produzir um material de partida sob uma forma granular e em um estado anídrico nanoporoso inclui obter um material de partida sob a forma de uma dispersão ou solução em um solvente sublimável ou misturas de solventes sublimáveis, formando gotículas graduadas por atomização, congelando as gotículas graduadas em um meio congelante em um índice de congelamento controlado de no mínimo 100°C por segundo para formar gotículas congeladas e secando as gotículas congeladas por sublimação a vácuo para obter grânulos secos por congelamento do material de partida em um estado anídrico nanoporoso. O material de partida sob forma de dispersão ou solução tem uma viscosidade adequada para atomização e formação de gotículas graduadas.
