Triclosan is a biocide that is used as an additive in many consumer products such as hand soaps, toothpastes, and cleaning supplies. With few exceptions, the health benefits of using triclosan containing personal care products have not been clearly established. There are concerns that triclosan may act as an endocrine disruptor and the US Food and Drug Administration is currently reviewing the safety of triclosan.1 Given that triclosan is produced in large quantities globally, and that a large proportion of the end-use products is disposed of in residential drains, it is not surprising that triclosan and related degradation products are routinely found in natural waters.2 Triclosan has been shown to be very susceptible to photodegradation and this has been shown as the predominant sink for this compound. However, the photoproducts generated from the photolysis of triclosan can include compounds such as dioxins and poly-chlorinated biphenyls (PCBs). This talk will focus on the experimental and theoretical results from our group that yield insights into the photophysics of triclosan and the mechanisms of photodegradation.
