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.

Sunscreen Intolerance: Contact Sensitization, Photocontact Sensitization, and Irritancy of Sunscreen Agents

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

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 ...

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 "

Sunscreening agents: a review.

The Journal of clinical and aesthetic dermatology, 2013
The increasing incidence of skin cancers and photodamaging effects caused by ultraviolet radiation has increased the use of sunscreening agents, which have shown beneficial effects in reducing the symptoms and reoccurrence of these problems. Many sunscreen compounds are in use, but their safety and efficacy are still in question.

Retardation Strategies for Sunscreen Agents

2017
Ultraviolet (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 ...

Chitosan microparticles incorporating a hydrophilic sunscreen agent

Carbohydrate Polymers, 2010
Abstract A microparticulate delivery system incorporating the hydrophilic sunscreen agent, phenylbenzimidazole sulphonic acid (PBSA) was prepared for better in-use performance. Chitosan, not adequately considered for sunscreen delivery, was used a matrix material.

Nanoparticles as delivery vehicles for sunscreen agents

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2012
Abstract 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 ...

Altered UV absorbance and cytotoxicity of chlorinated sunscreen agents

Cutaneous and Ocular Toxicology, 2012
Sunscreens 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,
