Abstract
This invention relates to homogeneous, anhydrous formulations which contain glycerophospholipids and polar or lipophilic substances (eg, physiologically active ingredients) in a molar ratio of 1:0.001 to 1:2, and maybe anhydrous formulation aids, eg, in the form of glycerol, in a molar ratio of 1:0.001 to 1:1, expressed in terms of the glycerophospholipids, the components forming such stable aggregates with one another as to render the formulations ideal for the preparation of dispersions, emulsions and/or suspensions in many fields of application, these including the food-processing sector, biotechnology, and the pharmaceuticals industry. The formulations are produced in an extraction column using compressed hydrocarbons, and are obtained from the column as a melt.
