US 12,703,142 B2 · Polyglycerol fatty acid ester-containing composition

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.
