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

Methods for the evaluation of melanin as a sunscreen agent
2023This thesis outlines the development of four new procedures (1) to synthesise melanins reproducibly, (2) to objectively determine the degree of structural similarity between melanins (3) to use diffuse reflectance to objectively measure skin colour and (4) to evaluate the SPF of melanin and other sunscreen formulations using in vitro methods.

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 ...

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,

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 ...

Technological strategies to improve photostability of a sunscreen agent
International Journal of Cosmetic Science, 2006Due to the reduction of the ozone layer, there is an increasing need of effective UV protection systems with minimized side‐effects. Trans‐2‐ethylhexyl‐p‐methoxycinnamate (trans‐EHMC) represents one of the most widely used sunscreen compound. Several studies demonstrated that trans‐EHMC is unstable following UV irradiation both in solution and in ...

Simultaneous determination of sunscreen agents in cosmetics by HPLC
Journal of the Korean Oil Chemists' Society, 2012The simultaneous analysis of sun screen agents in commercial cosmetic samples was carried out by High Perfomance Liquid Chromatography(HPLC). The cosmetic samples are directly dissolved in Tetrahydrofurane(THF) and filtered using 0.45 μm filter. The water/methanol/THF was used for the mobile phase of gradient conditions.

Chitosan microparticles incorporating a hydrophilic sunscreen agent
Carbohydrate Polymers, 2010Abstract 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.
