Exposure of humans to environmental phenolic compounds such as bisphenol A (BPA) and alkylphenols is a matter of concern, due to these compounds' ubiquitous occurrence and estrogenic potencies. Little is known about the levels of environmental phenolics in personal care products (PCPs). In this study, nonylphenol, two octylphenols, eight bisphenols (BPA and its analogs), and triclosan (TCS) were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) in PCP samples (n = 231) collected from China and the United States (U.S.). The concentrations of 4-n-nonylphenol (4-NP), 4-n-octylphenol (4-OP), 4-tert-octylphenol (4-t-OP), and TCS were in the ranges of < 0.5-39,100 [geometric mean (GM): 21.5], < 0.5-315 (0.680), < 1.0-10,100 (2.69), and < 0.5-53,900 (3.03) ng/g, respectively. The GM concentrations of individual bisphenols, including BPA, bisphenol S (BPS), and bisphenol F (BPF), were generally at sub-nanogram per gram levels. No significant differences in concentrations of the target compounds were found among various PCP categories or between China and the U.S. The estimated GM daily intakes of 4-NP, aOPs (sum of 4-OP and 4-t-OP), aBPs (sum of eight bisphenols), and TCS through dermal absorption from the use of PCPs were 0.932, 0.093, 0.072, and 0.016 mu g/day, respectively, for adult Chinese women and 0.340, 0.054, 0.120, and 0.068 mu g/day, respectively, for adult U.S. women. Body lotions, face creams, and liquid foundations accounted for the majority (> 85 %) of the dermal exposure doses of the target phenolics.
