  • Patent number: 12121613
    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.
