Production of powderous emulsions

The concentrated powder form (CPF) process allows the production of liquid-loaded, free-flowing powders. In the process a powderous carrier material is loaded with a liquid by a gas assisted high-pressure spraying process. A powderous emulsion is obtained, if the powderous carrier material is loaded with an emulsion. In this article is shown, how emulsions can be efficiently produced by a new high-pressure homogeniser and how they can be subsequently converted to a powderous emulsion. On the basis of examples it is also presented that powderous emulsions can be released almost unchanged in an adequate fluid. (C) 2008 Elsevier B.V. All rights reserved.
