The invention relates to a process for the production of sterols from fatty acid distillation residues, characterized in that the partial glycerides are subjected to a first transesterification step under mild conditions and, after working up and the removal of impurities, the sterol esters are subjected to a second transesterification step under more extreme conditions.

Processes for producing sterols from fatty acid production residues

A process for making granular solids involving: (a) providing a substantially anhydrous preparation, which is solid at room temperature and contain at least one cosmetic feed material; (b) liquifying the substantially anhydrous preparation to form a melt; (c) providing a vibrating casting plate used for droplet formation; (d) introducing the melt onto the vibrating casting plate to form melt droplets thereon; (e) providing a cooling medium; and (f) contacting the melt droplets with the cooling medium which is passed countercurrently to the melt droplets, thus forming the granular solids, and wherein the granular solids have a monodisperse particle size distribution and are substantially free of particles having a diameter of less than 0.3 mm.

Granular solid with monodisperse particle size distribution

A process for making spherically-shaped sterol preparations involving: (a) providing a liquid sterol preparation; (b) forming the liquid sterol preparation into liquid sterol droplets; and (c) solidifying the liquid sterol droplets to form the spherically-shaped sterol preparations.

Process for the production of triglycerides

A process for the continuous transesterification of C.sub.6 -C.sub.22 fatty acid lower alkyl esters, particularly methyl esters, with polyhydric C.sub.2 -C.sub.5 alcohols, particularly glycerol, in a reaction column comprising a rectifying and reaction section, alkaline catalysts and polyhydric alcohol are introduced into the upper part of the reaction column and boiling fatty acid methyl ester is introduced into the middle part of the reaction column. The product collected in the sump of the column is removed, heated and returned to the lower part of the reaction column. Product is removed from the sump. Lower alkanols passing from the reaction column section to the rectifying section are rectified. The reaction column is operated in boiling equilibrium in its lower part and predominantly in an absorption/desorption equilibrium in its upper part.

A process for reducing the free fatty acid content of fats and oils by esterifying the free fatty acids with a lower monoalcohol in the presence of an acidic cation exchange resin as a solid esterification catalyst.
