제목 Design of Ceramide Carriers via Liquid Crystalline Microdroplets
초록 Ceramides, which compose skin barrier, play a crucial role in preventing skin dehydration. Thus, supplying much of ceramides to skin is a major goal in cosmetic applications. To contain ceramides in cosmetics, lyotropic liquid crystals (LLCs) were used as a carrier. However, hydrogen bonds and hydrophobicity of ceramides, which cause crystallization in aqueous solutions, limit the content of ceramides.(<1%) Also, LLC carriers in aqueous solutions are not intrinsically unstable due to their hydrophilic nature. Here, to overcome the previous limitations, we propose a cholesteric thermotropic liquid crystals (CLCs) carrier that have biocompatible and hydrophobic nature. We demonstrate that the presence of hydrophobic (CLC)-hydrophilic (aqueous solution) interface enables the self-assembly of ceramides at the interface, thus significantly increasing the concentration of ceramides in the microdroplet carriers.
