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,
