Abstract: The present invention relates to compositions, such as bimatoprost, latanoprost and travoprost, and methods to reduce fat in the body of an individual, for example, by topical administration, injection, and/or implantation of such compositions.

Abstract: Aldehydes and/or alcohols are prepared by the hydroformylation of olefins of more than 3 carbon atoms by means of a bare rhodium catalyst dissolved homogeneously in the reaction medium, at superatmospheric pressure and at elevated temperatures, and separation of the rhodium catalyst from the liquid reaction mixture, by a process in which a magnetizable, inorganic pigment coated with a polymeric binder is used for separating the homogeneously dissolved, bare rhodium catalyst from the hydroformylation medium, and this pigment, after it has been laden with the rhodium contained in the hydroformylation medium, is separated from the liquid hydroformylation medium by applying an external magnetic field.
