Abstract:

Ultraviolet (UV) filters are used in cosmetics, personal care products and packaging materials to provide sun protection for human skin and other substances. Little is known about these substances, but they continue to be released into the environment. The acute toxicity of 4,4’-dihydroxybenzophenone, 2,4,4’-trihydroxybenzophenone and 4-MBC to Chlorella vulgaris and Daphnia magna were analyzed in this study. The 96 h-EC50 values of 4,4’-dihydroxybenzophenone, 2,4,4’-trihydroxybenzophenone and 4-MBC on C. vulgaris were 183.60, 3.50 and 0.16874 mg/L, respectively. The 48 h-LC50 of 4,4’-dihydroxy

The maximum absorption wavelength (λmax) of these samples was measured, and their UV resistance properties in cotton fabric as well as in polyester were determined. The results show that the λmax is dependent on the substituents at the benzylidene ring, and both electron donating substituents and electron withdrawing substituents caus

<strong>Study background:</strong> 2,4-Dihydroxybenzophenone (DHBP) is an organic compound used for the synthesis of pharmaceutical agents. The objective of this study was to investigate the influence of biofield energy treatment on the physical, thermal and spectral properties of DHBP. The study was performed in two groups (control and treated). The control group remained as untreated, and the treated group received Mr. Trivedi’s biofield energy treatment. <strong>Methods:</strong> The control and treated DHBP samples were further characterized by X-ray diffraction (XRD), differential s

Abstract:

AbstractOrganic UV filters (OUVFs), the active ingredient in sunscreens, are of environmental concern due to reported ecotoxicological effects in aquatic biota. Determining the environmental concentrations of these chemicals is essential for understanding their fate and potential environmental risk. Salting‐out assisted liquid–liquid extraction (SALLE) coupled with liquid-chromatography tandem mass spectrometry (LC–MS/MS) was developed for simultaneous extraction, separation, and quantification of seven OUVFs (2,4-dihydroxybenzophenone, 2,2′,4,4′-tetrahydroxybenzophenone, 4-methylbenzylidene c

Abstract:

ABSTRACTRationalBenzophenone derivatives, commonly used as UV filters in personal care products (PCPs), are widely prevalent and raise concerns due to their endocrine‐disrupting effects. Sensitive and efficient analytical methods are in demand for their detection. In this study, we developed a TAPB‐DMTP‐covalent organic framework (COF) nanofilm‐assisted laser desorption ionization mass spectrometry (LDI‐MS) method for the quantitative analysis of 2,4‐dihydroxybenzophenone (BP‐1) in PCPs.MethodsThe TAPB‐DMTP‐COF nanofilm was synthesized on indium tin oxide (ITO) glass and utilized as an LDI‐MS
