Anybody have experience in assaying for alpha hydroxy acids in cosmetics products? Is there a standardized FDA/USP test method? I have all sorts of HPLC systems and detectors available (UV, DAD, RI, conductivity, ELSD, fluorescence, and MS, as well as GC and GCMS (I'm also posting on the GC board).
