“…Above 250 nm, OCY has maximum absorbance at 304 nm, OCS and OCT both have absorbance maxima at 306 nm, OMC has a peak at 310 nm with a shoulder at about 295 nm, and BZ3 has two bands with peaks at 288 and 326 nm. These results are in agreement with those previously reported for these compounds [6][7]41]. Thus, appropriate Raman excitation wavelengths should lie in the 260-300 nm region in order to achieve resonance with these low-lying excited states.…”

“…The growing concern about the link between sunlight exposure and skin cancer has led to an increased use of BUVSs in sunscreens, soaps, shampoos, lip gloss, hair dyes and makeup, due to the presence of a phenolic group and benzotriazole structure that reflect and absorb the solar radiation (UVA 320–400 nm and UVB 290–320 nm) . The usual concentration of UV filters in cosmetics is between 0.1 and 10% .…”

Benzotriazole ultra-violet stabilisers are compounds widely used in personal care products, which can reach the environment after passing through wastewater treatment plants. In this work, we develop a novel method to evaluate the presence of seven compounds in marine sediments and sewage sludges using microwave-assisted extraction followed by a clean-up step based in on-line solid phase extraction coupled to ultra-high-performance liquid chromatography with MS/MS detection. This method allows for fast and efficient extraction from the solid matrix, subsequent automatic on-line purification and preconcentration, and analysis. For the optimised method, LOD were from 53.3 to 146 ng/kg and LOQ were in the range of 176-486 ng/kg. The method was validated for different environmental solid samples with satisfactory recoveries and relative standard deviations, between 46.1 and 83.9 and 7.8 and 15.5% (sludges) and 50.1 and 87.1% and 8.83 and 16.3% (sediments), respectively. Finally, the studied analytes were quantified in concentrations between 0.18 and 24.0 ng/g in real samples of marine sediments and sewage sludges from Gran Canaria Island (Spain).

“…While the concentration of BHT in these sunscreen products (1.01–1.33 mg/g) is lower than the concentration of BHT in other commercial products of sunscreen products reported by Capitán-Vallvey et al [4] (2.263 mg/g). On the other hand, the concentration range of OMC in these sunscreen products (16.23–65.50 mg/g) is low compared with previous studies for concentration range of OMC in other commercial sunscreen products reported by Chawla and Mrig [2] (56.12–91.02 mg/g), Wang and Chen [8] (18.3–80.1 mg/g), Chisvert et al [9] (19.5–90.5 mg/g), De Orsi et al [15](20–74 mg/g), and Chisvert et al [24] (5.8–77.8 mg/g).…”

An HPLC method with ultraviolet-visible spectrophotometry detection has been optimized and validated for the simultaneous determination of phenolic compounds, such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) as antioxidants, and octyl methyl cinnamate (OMC) as UVB-filter in several personal care products. The dynamic range was between 1 to 250 mg/L with relative standard deviation less than 0.25% (n = 4). Limits of detection for BHA, BHT, and OMC were 0.196, 0.170, and 0.478 mg/L, respectively. While limits of quantification for BHA, BHT, and OMC were 0.593, 0.515, and 1.448 mg/L, respectively. The recovery for BHA, BHT, and OMC was ranged from 92.1–105.9%, 83.2–108.9%, and 87.3–103.7%, respectively. The concentration ranges of BHA, BHT, and OMC in 12 commercial personal care samples were 0.13–4.85, 0.16–2.30, and 0.12–65.5 mg/g, respectively. The concentrations of phenolic compounds in these personal care samples were below than maximum allowable concentration in personal care formulation, that is, 0.0004–10 mg/g, 0.002–5 mg/g, and up to 100 mg/g for BHA, BHT, and OMC, respectively.
