Metabolism of oxybenzone in a hairy root culture: Perspectives for phytoremediation of a widely used sunscreen agent.[Pubmed:26736174]

J Hazard Mater. 2016 Apr 5;306:230-236.

Oxybenzone (OBZ), known as Benzophenone-3, is a commonly used UV filter in sun tans and skin protectants, entering aquatic systems either directly during recreational activities or indirectly through wastewater treatment plants discharge. To study the potential degradation capacity of plants for OBZ in phytotreatment, a well-established hairy root culture (Armoracia rusticana) was treated with OBZ. More than 20% of spiked OBZ (100muM) was eliminated from the medium by hairy roots after 3h of exposure. Two metabolites were identified as Oxybenzone-glucoside (OBZ-Glu) and Oxybenzone-(6-O-malonyl)-glucoside (OBZ-Mal-Glu) by LC-MS/MS and TOF-MS. Formation of these metabolites was confirmed by enzymatic synthesis, as well as enzymatic and alkaline hydrolysis. Incubation with O-glucosyltransferase (O-GT) extracted from roots formed OBZ-Glu; whereas beta-d-Glucosidase hydrolyzed OBZ-Glu. However, alkaline hydrolysis led to cleavage of OBZ-Mal-Glu and yielded OBZ-Glu. In the hairy root culture, an excretion of OBZ-Glu into the growth medium was observed while the corresponding OBZ-Mal-Glu remained stored in root cells over the incubation time. We propose that metabolism of Oxybenzone in plants involves initial conjugation with glucose to form OBZ-Glu followed by malonylation to yield OBZ-Mal-Glu. To our best knowledge this first finding presenting the potential of plants to degrade benzophenone type UV filters by phytoremediation.

Simultaneous Determination of Octinoxate, Oxybenzone, and Octocrylene in a Sunscreen Formulation Using Validated Spectrophotometric and Chemometric Methods.[Pubmed:26525239]

J AOAC Int. 2015 Sep-Oct;98(5):1215-25.

Accurate, reliable, and sensitive spectrophotometric and chemometric methods were developed for simultaneous determination of octinoxate (OMC), Oxybenzone (OXY), and octocrylene (OCR) in a sunscreen formulation without prior separation steps, including derivative ratio spectra zero crossing (DRSZ), double divisor ratio spectra derivative (DDRD), mean centering ratio spectra (MCR), and partial least squares (PLS-2). With the DRSZ technique, the UV filters could be determined in the ranges of 0.5-13.0, 0.3-9.0, and 0.5-9.0 mug/mL at 265.2, 246.6, and 261.8 nm, respectively. By utilizing the DDRD technique, UV filters could be determined in the above ranges at 237.8, 241.0, and 254.2 nm, respectively. With the MCR technique, the UV filters could be determined in the above ranges at 381.7, 383.2, and 355.6 nm, respectively. The PLS-2 technique successfully quantified the examined UV filters in the ranges of 0.5-9.3, 0.3-7.1, and 0.5-6.9 mug/mL, respectively. All the methods were validated according to the International Conference on Harmonization guidelines and successfully applied to determine the UV filters in pure form, laboratory-prepared mixtures, and a sunscreen formulation. The obtained results were statistically compared with reference and reported methods of analysis for OXY, OMC, and OCR, and there were no significant differences with respect to accuracy and precision of the adopted techniques.

Photodynamics of oxybenzone sunscreen: Nonadiabatic dynamics simulations.[Pubmed:27544106]

J Chem Phys. 2016 Aug 21;145(7):074308.

Herein we have used combined static electronic structure calculations and "on-the-fly" global-switching trajectory surface-hopping dynamics simulations to explore the photochemical mechanism of Oxybenzone sunscreen. We have first employed the multi-configurational CASSCF method to optimize minima, conical intersections, and minimum-energy reaction paths related to excited-state intramolecular proton transfer (ESIPT) and excited-state decays in the (1)pipi( *), (1)npi( *), and S0 states (energies are refined at the higher MS-CASPT2 level). According to the mapped potential energy profiles, we have identified two ultrafast excited-state deactivation pathways for the initially populated (1)pipi( *) system. The first is the diabatic ESIPT process along the (1)pipi( *) potential energy profile. The generated (1)pipi( *) keto species then decays to the S0 state via the keto (1)pipi( *)/gs conical intersection. The second is internal conversion to the dark (1)npi( *) state near the (1)pipi( *) /(1)npi( *) crossing point in the course of the diabatic (1)pipi( *) ESIPT process. Our following dynamics simulations have shown that the ESIPT and (1)pipi( *) --> S0 internal conversion times are 104 and 286 fs, respectively. Finally, our present work demonstrates that in addition to the ESIPT process and the (1)pipi( *) --> S0 internal conversion in the keto region, the (1)pipi( *) --> (1)npi( *) internal conversion in the enol region plays as well an important role for the excited-state relaxation dynamics of Oxybenzone.

Chlorination of oxybenzone: Kinetics, transformation, disinfection byproducts formation, and genotoxicity changes.[Pubmed:27085067]

Chemosphere. 2016 Jul;154:521-527.

UV filters are a kind of emerging contaminant, and their transformation behavior in water treatment processes has aroused great concern. In particular, toxic products might be produced during reaction with disinfectants during the disinfection process. As one of the most widely used UV filters, Oxybenzone has received significant attention, because its transformation and toxicity changes during chlorine oxidation are a concern. In our study, the reaction between Oxybenzone and chlorine followed pseudo-first-order and second-order kinetics. Three transformation products were detected by LC-MS/MS, and the stability of products followed the order of tri-chloro-methoxyphenoyl > di-chlorinated Oxybenzone > mono-chlorinated Oxybenzone. Disinfection byproducts (DBPs) including chloroform, trichloroacetic acid, dichloroacetic acid and chloral hydrate were quickly formed, and increased at a slower rate until their concentrations remained constant. The maximum DBP/Oxybenzone molar yields for the four compounds were 12.02%, 6.28%, 0.90% and 0.23%, respectively. SOS/umu genotoxicity test indicated that genotoxicity was highly elevated after chlorination, and genotoxicity showed a significantly positive correlation with the response of tri-chloro-methoxyphenoyl. Our results indicated that more genotoxic transformation products were produced in spite of the elimination of Oxybenzone, posing potential threats to drinking water safety. This study shed light on the formation of DBPs and toxicity changes during the chlorination process of Oxybenzone.
