PROCESS OF PREPARING A WATER DISPERSIBLE HYDROPHOBIC OR AEROPHILIC SOLID

摘要

Process of preparing a hydrophobic/aerophilic solid which can be dispersed in water in the form of discrete microparticles, wherein the solid is milled in an aqueous medium in the presence of a hydrocolloid to obtain a suspension containing suspended particles of an average particle size not exceeding 10 .mu.m and finely dividing and drying the suspension to obtain a powder.
