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.

Homogenous water-free formulations containing glycerophospholipids and polar or lipophilic substances, method for the production thereof

The invention relates to oil-free glycerophospholipid formulations which contain a homogeneous mixture of glycerophospholipids and an anhydrous, liquid polyol compound such as glycerol in a molar ratio of 1:0.1 to 1. These formulations are produced, eg, by extracting a starting material consisting of an oil-containing glycerophospholipid (mixture) and the polyol component with a compressed hydrocarbon (mixture) in a rectifying column. The oil-free formulation can be obtained from the melt at the bottom of the column in the form of free-flowing powder, which is ideally suited for stabilising oil-in-water emulsions.
