“…Thus, thymol dissolved in oleic acid presents two bands centered at 379 and 435 nm. The appearance of two emission bands may be ascribed to the formation of thymol clusters, in agreement with results found for other aromatic alcohols [33].…”

Essential oil compounds (EOCs) are molecules with well-known antimicrobial and antipest activity. However, such molecules possess limited solubility in water, making their handling difficult. This work aimed to enhance the distribution of a solid essential oil compound, thymol, using oil-in-water (o/w) microemulsions for its solubilization. The use of mixtures formed by an alkyl polyglucoside (APG) and soybean lecithin (SL) allowed for stabilization of the o/w microemulsions in a broad range of compositions, with the total concentration of the mixture of the two surfactants (APG+SL) and the APG:SL ratio both being essential for controlling the nature of the obtained dispersions. The microemulsions obtained using oleic acid as the oil phase and with compositions far from those corresponding to the onset of the emulsion region showed a good efficiency for thymol solubilization. This is an advantage from a stability point of view, as well as for ease of thymol preparation. The present work opens new alternatives for designing eco-sustainable formulations for EOC solubilization, with the possibility of preparing the formulations at the place of use, thereby saving transport costs and reducing the emission of pollutants.

“…This can be attributed to the increase in the concentration of excited molecules and decline in the ground state population as the power density is increased up to 30 MW/cm 2 . The discussion of the phenol photolysis products is beyond the scope of this paper and is given, for example, in [16][17][18].…”

Photolysis of phenol andp-chlorophenol exposed to KrCl- and Nd-YAG laser light is studied by electron spectroscopy and fluorescence and quantum chemical techniques. The decrease of the quantum yield of phenol fluorescence with increase in the excitation energy is not related to dynamic changes in the intramolecular photophysical processes; rather this is a result of increased photoreaction efficiency. Chlorine substitution for para-state of phenol is shown to strengthen the OH-bond in excitation into the long wavelength absorption band.

“…The fluorescence band with the maximum between 450-550 nm generated by photoproducts disappears after UV irradiation of phenol in the aquatic and saline solutions. We recorded this photoproduct after irradiation of phenol in the alkaline solution by the high-power XeCl-laser radiation (170 MW/cm 2 ) with an exciting radiation wavelength of 308 nm [7]. It is most likely that the nature of the product formed upon exposure to high-power laser radiation or after microbial destruction of phenol in the water solution is the same.…”

The present work is aimed at spectroscopic and luminescent investigations of the microbial cleavage efficiency of phenol in the water solution upon expose to UV light. With increasing time of irradiation of phenol in the saline solution, the absorption intensity increases throughout the spectrum. The efficiency of photoalteration of phenol in the saline solution is higher compared to that in water. The results obtained have shown that the efficiency of complex photobiological phenol destruction increases sharply compared to the photochemical or microbial destruction.
