Wherever substances in complex matrices have to be analyzed HPTLC is the method of choice. It allows to easily confirm or reject the identity of raw materials. HPTLC is used in many laboratories worldwide for routine quality control.
Cosmetic products are often complex mixtures, difficult to analyze because of possible interferences by their different components. Therefore, the incorporation of active ingredients into the various formulations requires the development of suitable analytical methods for quality control. HPTLC has the capability for dealing with complex matrices. Examples for cosmetic applications can be found in our customer magazine CBS and the CCBS database. For example, in the CBS 118 (pp. 5–7) two typical applications are demonstrated. The first one describes a general method for detection and identification of UV filter in sun cream. The second one describes a method for the detection of phenolic markers specific to Edelweiss species in order to qualify different sources and grades of raw materials as well as glycerol-based cosmetic ingredients used for cosmeceutical products.
The use of standardized HPTLC methods allows you to clearly identify natural materials, regardless of the source, based on their chromatographic fingerprint. Additionally, HPTLC is a powerful tool to rapidly compare several samples in parallel, check for adulteration, monitor purity and stability, and quantify marker compounds.
