Padimate A is an organic compound that is an ingredient in some sunscreens. It is an ester derivative of PABA. This aromatic chemical absorbs ultraviolet rays thereby preventing sunburn. However, it's chemical structure and behaviour is similar to an industrial free radical generator. In Europe this chemical was withdrawn in 1989 for unstated reasons. In the US it was never approved for use in sunscreens.
