PHOTODERMATITIS FROM A SUNSCREENING AGENT

Archives of Dermatology, 1970
To the Editor.— This is a report of contact photodermatitis from the sunscreening agent 2-ethoxyethyl p -methoxycinnamate (EEMC). This agent is present in numerous sun-protective preparations. It rarely causes allergic contact dermatitis. 1 Report of a Case.— A 60-year-old white woman presented with an acute erythematous and vesicular eruption ...

The efficacy of sunscreening agents: protection factors and transmission spectra

Clinical and Experimental Dermatology, 1982
Summary Fifty-five sunscreening agents were tested for their protection factor (PF) against ultraviolet radiation (UVR) and for transmission between 280 and 600 run. The results are tabulated so that the less efficacious sunscreens, although suitable for protection against natural and artificial light in people with normal skin, may be separated ...

Quinolines derivatives as novel sunscreening agents

Bioorganic & Medicinal Chemistry Letters, 2013
Currently, the research and development of sunscreens play an important role on the synthesis of actives that are stable in various kinds of formulations-in addition to their efficiency and broad spectrum of protection against ultraviolet radiation. Our objective here was to synthesize new sunscreening chemical agents using quinoline as a base molecule.

Determination of sunscreen agents by micellar electrokinetic chromatography

Journal of Pharmaceutical and Biomedical Analysis, 1995
The separation of UV-A and UV-B sunscreens by micellar electrokinetic chromatography has been studied. The optimized method, which involves the presence of an anionic surfactant (sodium dodecyl sulphate) and an organic modifier in the background electrolyte, was applied to determine these sunscreens in cosmetic products. Identification was achieved by "
