✦ Synopsis

Cosmetic creams were anz.,,zed . Jr the.. content of jojoba wax and shea fat using anticircular HPTLC, a fast, precise, and reliable method. After optimization of the solvent system (petrol ether/diethyl ether) for the separation of jojoba wax and shea fat, the spots were visualized with phosphomolybdic acid by the "dip-in" technique, subsequently heated, and finally recorded by scanning with a densitometer at 546 nm. Results showed that one particular concentration rangegivesanoptimum correlation between calibration curves and sample evaluations.
