AB Sunscreens have become a product based on increasingly complex formulations that include, among many ingredients, a mixture of UV filters to provide optimal sun ultraviolet radiationprotection. A significant group of scientific works deals with the impact of UV filters in aquatic media.However, the knowledge of the mechanism and kinetics of the compound’s direct release, fate, andits transformation and interaction with living organisms is necessary to assess its environmentaloccurrence and behavior and to predict potential and real impacts on the aquatic environment. Thisreview outlines the existing analysis and modeling of the release and behavior of sunscreen’s ingredients in the marine environment, including aquatic organisms. The physical-chemical properties,photodegradation, and release kinetics of particles and chemicals into the water are studied byhydrodynamic and kinetic models. Direct photolysis of chemicals is modeled as pseudo-first-orderkinetics, while the indirect pathway by the reaction of sunscreen with reactive oxygen species isdescribed as second-order kinetics. The interaction of UV filters with marine biota is studied mainlyby toxicokinetic models, which predict their bio-accumulation in the organisms’ tissues. Thesemodels consider the chemicals’ uptake and excretion, as well as their transfer between differentinternal animal organs, as a first-order kinetic process. The studies analyzed in the present workrepresent a driver of change for the beauty and personal care industry, in order to seek new ecologicalalternatives through the application of R&D tactics.
