In vitro skin permeation of sunscreen agents from O/W emulsions
International Journal of Cosmetic Science, 2008The effects of different emulsifiers on the in vitro permeation through human skin of two sunscreen agents [octylmethoxycinnamate (OMC) and butylmethoxydibenzoylmethane (BMBM)] were investigated from O/W emulsions. The test formulations were prepared using the same oil and aqueous phase ingredients and the following emulsifier and coemulsifier systems:

EFFECT OF IMMUNOSUPPRESSIVE AGENTS AND SUNSCREENS ON UV CARCINOGENESIS IN THE HAIRLESS MOUSE
Australian Journal of Experimental Biology and Medical Science, 1985SummaryThe effect of two immunosuppressive agents, azathioprine and cyclophosphamide, with and without UVB sunscreen protection on UV‐induced skin carcinogenesis was studied in the albino hairless mouse.In a daily treatment regime spanning 9 weeks, groups of mice were immunosuppressed with either drug, and were exposed to minimally erythemal doses of a

The study on the photostability of six UV filters in aqueous solution was combined with investigations on the phytotoxicity of the produced degradation mixtures. During the exposure to artificial sunlight over 72 h, the degradation of three of the UV filters evaluated was observed with half-lives between 20 and 59 h.

[Evaluation of sunscreening agents].
Zeitschrift fur Hautkrankheiten, 1989Sunscreen preparations are evaluated according to their protection power against biological effects of ultraviolet radiation. UV-induced phenomena found on protected skin are compared with those on unprotected skin; thus the sunprotection factor is estimated.

Nanopumpkins and a sunscreen agent: the inclusion complex of cucurbituril and Tinosorb S
Supramolecular Chemistry, 2011The commercial sunscreen agent Tinosorb S (TS) is a promising oil-soluble broad spectrum UV filter. Here, we report for the first time a water-dispersible inclusion complex of TS using cucurbituril. The synthesis was carried out via a supramolecular approach in the solid state by using the high-speed vibration milling technique.

Photodecomposition of several compounds commonly used as sunscreen agents
Journal of Photochemistry and Photobiology A: Chemistry, 1994Abstract The photolysis reactions of three compounds commonly used as a sunscreen agents, Parsol 1789 (1-[4-(1,1-dimethylethyl)phenyl]-3-(4-methoxyphenyl)-1,3- propanedione), Oxybenzone ((2-hydroxy-4-methoxyphenyl)phenyl-methanone) and Padimate O (2-ethylhexyl-4-(dimethylamino)benzoate), were investigated to provide a chemical background to aid in ...

Dermal delivery by niosomes of black tea extract as a sunscreen agent
International Journal of Dermatology, 2012AbstractObjectives The primary objective of this study was to investigate the feasibility of using niosomes as a delivery vehicle for the dermal administration in vitro of black tea extract (BTE) as a sunscreen.Methods Multi‐lamellar niosomes were obtained by means of a previously reported method of lipid hydration films.

Voltammetric Behavior of Sunscreen Agents at Mercury Film Electrode
Electroanalysis, 2002The voltammetric behavior of sunscreen agents on glassy carbon and mercury film electrodes was investigated in aqueous media containing various supporting electrolytes. The possible reaction mechanisms were discussed by the relations of pH values and peak potentials and currents.
