15 صفحه اولQuantification of Sunscreen Benzophenone-4 in Hair Shampoos by Hydrophilic Interactions Thin-Layer Chromatography/Densitometry or Derivative UV Spectrophotometry
Benzophenone-4 (BZ4) was separated from surfactants, dyes, preservatives, and other components of hair shampoos by thin-layer chromatography on silica gel 60 stationary phase, with ethyl acetate-ethanol-water-pH 6 phosphate buffer (15 : 7 : 5 : 1 v/v/v/v) as mobile phase. Densitometry scanning of chromatograms was performed at 285 nm. The densitometric calibration curve for BZ4 was nonlinear (s...

Thin-layer chromatography of ceramides.
Ceramides with mono-, di-, and trihydroxy long-chain bases, and normal (saturated and unsaturated), branched-chain, and 2-hydroxy fatty acids have been analyzed by thin-layer chromatography. In most cases the compounds were also run as acetates. Borate, arsenite, and silver ions were used as complexing agents, and the effects of number, position, and stereochemistry of hydroxy groups, and of un...
متن کاملThin-layer Chromatography of Lipids
There has been a tendency to discount thin-layer chromatography (TLC) in recent years because of the availability of high-performance liquid chromatography (HPLC) methods that appeared to offer greater versatility and ease of quantification, amongst other reasons. However, TLC has made a comeback, largely because of the high reproducibility and lower costs of commercial pre-coated plates. It is...
