An improved high-performance thin-layer chromatographic (HPTLC) method has been developed for quantitative analysis of stratum corneum lipids. When used for quantification of in-vivo-extracted skin lipids, the optimized method resulted in improved se

The class of fatty alcohol alkoxylates describes surfactants that are synthesised by reaction of fatty alcohols with alkoxides such as ethylene oxide or propylene oxide or a combination of both as copolymers. Such alkoxylates are used, for example, a

Reactive oxygen molecules are formed in vivo as by-products of normal aerobic metabolism. All organisms dependent on oxygen are inevitably exposed to these species so that DNA damage can occur in both genomic and mitochondrial DNA (mtDNA). In order t
