Apart from being an analogue of the prototype for photoinduced intramolecular charge transfer (ICT), 2-ethylhexyl 4-dimethylaminobenzoate (EHDMABA) is also one of the earliest patented and most commonly used sunscreen components. There is, however, little documented information about the photophysics and factors affecting the photophysics of this molecule.

The stereoselective metabolism of the enantiomers of the UV-filter 2-ethylhexyl 4-dimethylaminobenzoate (EDP) in rabbits was studied. The two major metabolites 4-(N,N-dimethylamino) benzoic acid (DMP) and 4-methylaminobenzoic acid (MMP) were also investigated in vivo and in vitro. Cytotoxicity of EDP and its two metabolites was also investigated in hepatocytes.
