Assessment of UV filter ethylhexyl methoxycinnamate photoisomerization in aquatic environments, cosmetics and in vitro skin by (micro)extraction GC–MS analysis

Key Points

• Photoisomerization of ethylhexyl methoxycinnamate occurs across diverse environments, impacting aquatic ecosystems.
• Key finding indicates that UV filters can break down into different forms when exposed to light, which may affect their safety.
• Assessment through microextraction and GC-MS analysis reveals varying concentrations of photoisomers in cosmetics and skin samples.
• Highlights potential environmental risks of UV filters, emphasizing the need for further research and monitoring.
