Abstract: The invention relates to a polyglycerol fatty acid ester-containing composition which has the following three components, namely: first, polyglycerol fatty acid esters that can be obtained by esterifying polyglycerols, which have 2 to IO glycerol units, with fatty acids with 12 to 22 carbon atoms; second, free poly glycerols, which have 2 to IO glycerol units; and third, polyglycerol fatty acid monoesters, which have 2 to IO glycerol units and fatty acid groups with 12 to 22 carbon atoms. The composition is suitable in particular for use in starting materials for a 3D printing method and can be readily combined with cosmetic and/or pharmaceutical active ingredients or other substances. The invention also relates to methods for producing corresponding starting materials for a likewise described 3D printing method and to molded bodies which can be produced using same.

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.

Abstract: The invention relates to an additive for a powder material intended for compaction into shaped bodies. The additive is used to influence the powder material with regard to its cohesion and slidability on foreign surfaces and comprises as the main constituent one or more polyglycerol fatty acids, 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 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.
