Abstract (en)
[origin: WO02094428A1] The invention relates to particulate solids containing more than 90% by weight, preferably more than 98% by weight of natural or synthetic surface active compounds. The invention is characterized by the following: (a) the mean particle size of the solid particles is 10 - 3000 mu m; (b) the surface active compounds are solid at room temperature and (c) the surface active compounds have a melting point of 25 to 250 DEG C, preferably 30 - 130 DEG C, more particularly 35 - 90 DEG C. The invention also relates to a method for the production of particulate solids of surface active compounds, which is characterized in that the compounds are introduced in liquid form into a cryogenic gas forming droplets at a temperature above melting point, are cooled in solid state and separated from the cryogenic gas in the form of a particulate solid.
