      CBS 111, 5-6 (2013). HPTLC of caffeine, taurine, and arginine in shampoo samples extracted with isopropanol, on silica gel over 50 mm with isopropanol - n-heptane - water 7:3:1 for caffeine and isopropanol - water 4:1 for arginine and taurine. Detection under UV 254 nm (caffeine) and after spraying with ninhydrin reagent under white light (arginine and taurine). Quantitative absorbance measurement at UV 254 nm for caffeine and UV 600 nm for arginine and taurine. The hRF of caffeine was 54. Precision (%RSD) for the polynomial calibration of caffeine was 3.9 % (n=3). The hRf of taurine was 24. Arginine remained at the start position under these conditions. The content of taurine and caffeine found in shampoos corresponded to the usual amount of 0.1 % active ingredient in a formulation.
