Abstract: The invention relates to a coating material for use in a hot-melt coating method, said material containing as the main constituent one or more polyglycerol fatty acid, each obtained by way of a complete or partial esterification of a linear or branched polyglycerol containing two to eight glyceryl units with one or more fatty acids, each containing 6 to 22 carbon atoms.

Abstract: The invention relates to lipophilic transport particles for cosmetic or pharmaceutical active ingredients. The lipophilic transport particles comprise polyglycerol fatty acid ester as a main constituent and, because of the absence of polymorphic transformations, even during long storage, neither have volume changes nor allow the problem of expulsion of the adhering or enclosed active ingredient, due to intense structuring of the crystal lattice and associated compaction, to arise, and therefore the degree of loading with active ingredient and the release profile are stable.

Abstract: The invention relates to a method for producing fatty alcohol esters of 3-hydroxybutyric acid and their acylated derivatives, as well as the products thus obtained and their use.

Abstract: A process is described for the preparation of polyglycerol fatty acid esters from a reaction mixture to which a metallic catalyst is added, as well as to a method for the purification of an intermediate synthesis product which contains excess fatty acid in addition to polyglycerol fatty acid esters. Compared with the prior art, a significantly improved yield and a higher process speed is obtained along with more economic use of raw materials, auxiliary materials, solvents and energy.
