Abrégé
The invention relates to the marking of textile products that have been dyed using a supercritical dyeing process. More particularly, the invention provides a process of marking a textile substrate with a tracer, said process comprising contacting the textile substrate with a supercritical or near-critical dyeing medium containing a dye and a tracer, said tracer being selected from a metal chelate and a chemiluminescent agent. The process of the present invention uses the supercritical or near-critical dyeing medium as a vehicle for depositing a tracer onto the textile substrate that is also dyed using this medium. The presence of the deposited tracer on the dyed textile can be detected using a simple and reliable authentication method. The invention also concerns a marked textile product obtained by the aforementioned process. Also provided are a dyeing composition that can be used in the aforementioned process as well as methods for authenticating textile products that have been marked using his process.

Disclosed is a novel method of making a structuring agent for edible dispersions such as margarines or spreads. Fat, or another structuring component, is subjected to a process involving mixing it with liquefied gas or supercritical gas, and expanding the mixture through an orifice. In the invention, water is added to the mixture prior to expansion, so as to provide a spray liquid in the form of a fat and water emulsion.

The present invention relates to a method of preparing a pharmaceutical co-crystal composition, said method comprising the steps of: a. simultaneously contacting a supercritical or liquefied gas with solid particles of a pharmaceutically active component and with solid particles of a co-builder to form a co -crystallisation medium containing dissolved pharmaceutically active component and dissolved co-builder as well as solid particles of the pharmaceutically active component and solid particles of the co-builder; b. transforming the solid particles of the pharmaceutically active component and the solid particles of the co-builder into co-crystals of said pharmaceutically active component and said co-builder by keeping the supercritical or liquefied gas in a supercritical or liquid state until at least 80 wt.% of the pharmaceutically active component is incorporated in the crystal matrix of said co-crystals; and c. separating said co-crystals from the supercritical or liquefied gas wherein at least a fraction of the pharmaceutically active component and at least a fraction of the co-builder remain in an undissolved state during the co-crystallisation. The present method enables easy preparation of a pharmaceutical co-crystal composition containing virtually no solvent residue and can suitably be used to prepare co-crystals of highly labile pharmaceutically active components.

The invention relates to a method for desolventising a contaminated solid particulate composition containing: - at least 10 wt.% of a solid pharmaceutically active ingredient or of a solid intermediate product of the manufacture of a pharmaceutically active ingredient; - not more than 70 wt.% of contaminating solvent; and - optionally, up to 89 wt.% of inert carrier; said method comprising the steps of: a) contacting the contaminated solid particulate composition with a liquefied gas; b) allowing the contaminating solvent to become entrained in the liquefied gas; c) separating liquefied gas containing entrained contaminating solvent from the residual solid particulate composition; and d) removing liquefied gas from the residual solid particulate composition through evaporation; wherein all of the aforementioned steps are performed at a temperature below 100 ºC and below the critical temperature of the liquefied gas, and wherein steps a) to c) are performed at a pressure of at least 5 bar. Although the present method employs mild processing conditions, it enables essentially complete solvent removal.
