An unexpected chlorination of an organic sunscreen
The origin of intense red staining on fabrics contaminated by sunscreen and treated with bleach has been attributed to an unexpected dichlorination of a common UV filter. The structure of the chromophore has been determined by NMR spectroscopy, and the proposed mechanism of its formation is supported by DFT calculations.
