  • Publication number: 20030113354
    Abstract: A granular solid with monodisperse particle size distribution is disclosed, which may be obtained by melting an essentially anhydrous composition, which is solid at room temperature and made from at least one cosmetic ingredient. A flow of the melt is dispersed into droplets by means of a casting plate and vibration and said droplets contacted with a cooling medium, which causes the solidification thereof.

  • Patent number: 6093844
    Abstract: Proposed is a method of producing alkaline-earth salts of aliphatic .beta.-keto compounds by reacting alkaline-earth hydroxides with aliphatic .beta.-ketoesters and/or .beta.-diketones in the absence of solvent to give the corresponding alkaline-earth salts. The .beta.-keto compound is added in portions to the powdered alkaline-earth hydroxide and the reaction mixture subsequently dried. Good yields are obtained of a fine-grained, light colored product.

  • Patent number: 5254722
    Abstract: A process for the production of triglycerides of C.sub.1 -C.sub.4 alkyl esters of C.sub.6 -C.sub.22 fatty acids:a) where dry sodium carbonate catalyst is dissolved in glycerol and mixed with a molar excess of preferably the methyl ester of C.sub.6 -C.sub.22 fatty acid at a temperature between about 150.degree. C. and 250.degree. C. at less than atmospheric pressure and under substantially anhydrous conditions to produce an initial reaction mixture containing the corresponding triglycerides of said fatty acids, and partially reacted glycerol with unreacted hydroxyl groups (OH values 10-40),b) thereafter, a portion of the initial reaction mixture is reacted with additional C.sub.1 -C.sub.4 alkyl ester of C.sub.6 -C.sub.22 fatty acid under conditions to achieve substantially full conversion of said unreacted hydroxyl groups (OH values of 5 or less), andc) a product containing the corresponding triglycerides of said fatty acids is separated from unreacted alkyl ester and from the sodium carbonate catalyst.

  • Patent number: 4976892
    Abstract: 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.
