Phthalates and Parabens in Personal Care Products From China: Concentrations and Human Exposure

Our previous studies showed that populations in China are widely exposed to phthalates and parabens. Nevertheless, sources of Chinese exposure to phthalates and parabens are not well understood. In this study, we measured concentrations of nine phthalates and six parabens in five categories of personal care products (PCPs, N = 52) collected from Tianjin, China, and estimated human exposure doses to these compounds. The most frequently detected phthalates and parabens in PCPs were diethyl phthalate (DEP) (detection frequency 54 %), methyl paraben (MeP), and n-propyl paraben (PrP) (~75 %). The concentrations of DEP in PCPs ranged from not detected (ND;
