Since window glass absorbs sunlight below 320 nm, it provides a means of assessing sensitivity to longer wavelengths, i.e. UVA and visible radiation. Positive responses to the query of whether symptoms develop in the auto with the windows up must

On illumination with simulated sunlight, the UVB-absorbing sunscreen chemical 2-ethylhexyl-4-dimethylaminobenzoate (Padimate-O) generates excited species which inflict non-ligatable strand breaks on DNA in vitro and it also becomes mutagenic to yeast in vivo. Padimate-O is known to penetrate human skin but

In previous experiments, it was suggested that the reduction in estradiol (E2) buccal permeability after pretreatment with some skin penetration enhancers was attributed to enhanced membrane storage. To verify this, further in vitro permeability experiments were performed and the kinetics

We describe an in vitro approach to assessing the potential genotoxicity of illuminated sunscreens. The photomutagenic sunscreen Padimate-O attacks DNA on illumination with simulated sunlight, producing strand breaks and lesions that are labile to N,N'-dimethylethylenediamine but few, if any, cyclobutane

This study compares the ability of two ultraviolet (UV) B-absorbing sunscreens, 2-ethylhexyl p-methoxycinnamate (2-EHMC) and 2-ethylhexyl p-aminobenzoate (Padimate O), and two physical sunscreens, microfine titanium dioxide (MTD) and zinc oxide, to protect the skin immune system from chronic (4 weeks)
