Development and analysis of different phospholipid formulations for dermal application and their effect on human dermal cell viability
Phospholipid-based formulations have gained major interest in the field of topical drug delivery due to their physical-chemical properties. As amphiphilic constituents of cellular membranes, phospholipids exhibit both high biocompatibility and great emulsifying power. Thus, plentiful phospholipid-based formulations and drug carriers such as liposomes, solid-lipid nanoparticles (SLNs), micelles, and organogels have been developed and investigated by different research groups.1)2)3)4)5)6)
In the project, a range of phospholipids will be used to prepare different formulations. Importantly, the focus of this project is the evaluation of the employed phospholipids and the developed formulations on the cell viability of viable human keratinocytes and fibroblasts as determined by cell culture toxicity tests. To this end, a specific dermal cell culture line will be established in the laboratory. In addition, the effect of the formulations on skin penetration and permeation of incorporated model drugs will be determined.
Benefit for the community
The results will contribute to the general knowledge in the field of cytotoxicity of dermal formulations and especially of phospholipids. Moreover, feedback will be collected from colleagues within this and related fields of research and this interdisciplinary exchange will stimulate new creative approaches towards scientific use of natural phospholipids in dermal formulations as well as for natural cosmetics.
