PHOTODERMATITIS FROM A SUNSCREENING AGENT
Archives of Dermatology, 1970To 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 ...

Dermatologic Clinics, 1995
Reports of contact sensitization and photocontact sensitization induced by various sunscreening agents are reviewed. Current knowledge about the most often used sunscreening agents is summarized. The problems of cross-sensitization and sensitization in photodermatoses are discussed. Strategies for patch and photopatch testing, as well as immediate-type

Determination of sunscreen agents by micellar electrokinetic chromatography
Journal of Pharmaceutical and Biomedical Analysis, 1995The 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 "

The efficacy of sunscreening agents: protection factors and transmission spectra
Clinical and Experimental Dermatology, 1982Summary 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 ...

Nanoparticles as delivery vehicles for sunscreen agents
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2012Abstract Sunscreen filters, which block hazardous UV radiation, are commonly applied in cosmetic products to protect the skin, the hair, or the product itself. Most sunscreen formulations are emulsions or creams. However, formulations based on nanoparticles as the delivery vehicle for the sunscreen compounds potentially have advantages in terms of ...

Potentials of Botanicals as Sunscreen Agents: A Review
Research Journal of Pharmacognosy and Phytochemistry, 2018Sun exposure is the main etiological agent for most type of skin cancer, photocarcinogenesis, photo ageing, thus adequate photoprotection is essential to control UV related disorders. Approaches including use of physical photoprotective agents and sunscreen are used widely but in addition to this there are agents who can further improve the effect of ...

Retardation Strategies for Sunscreen Agents
2017Ultraviolet (UV) radiation exposure from the sun and artificial UV sources has been widely acknowledged as the major culprit for skin cancer and premature skin aging. Skin cancers are among the most dangerous (cutaneous malignant melanoma) and the most numerous (basal cell carcinoma, actinic keratosis, and invasive squamous cell carcinoma) of all ...

Electroanalytical determination of the sunscreen agent octocrylene in cosmetic products
International Journal of Cosmetic Science, 2011SynopsisAn electroanalytical method was developed to detect and quantify the sunscreen agent octocrylene (OCR) in cosmetic products. The method was based on electrochemical reduction, using voltammetric techniques. OCR was reduced at −0.97 V vs. Ag/AgCl on a glassy carbon electrode using a mixture of Britton–Robinson buffer (0.04 mol L−1) and ethanol ...

Altered UV absorbance and cytotoxicity of chlorinated sunscreen agents
Cutaneous and Ocular Toxicology, 2012Sunscreens are widely utilized due to the adverse effects of ultraviolet (UV) radiation on human health. The safety of their active ingredients as well as that of any modified versions generated during use is thus of concern. Chlorine is used as a chemical disinfectant in swimming pools. Its reactivity suggests sunscreen components might be chlorinated,
