The exposures of a wide range of endocrine-disrupting chemicals to cows have been linked to diseases and are a major concern. In Indian scripts, cow urine is believed to be a treatment for many diseases. Nonetheless, exposure of bisphenols and parabens to cow urine distillates is unknown. Hence, in this study, we determined the concentration of bisphenols and parabens in commercially available cow urine distillate collected from India. The mean concentration of total bisphenols and parabens ranges from the limit of quantification (LOQ) to 149.3 ng/mL and 1479.88 ng/mL, respectively. Predominant bisphenol-F and bisphenol-A were accounted for 88.6% and 6% of total bisphenol concentration, respectively, in marketed cow urine distillate, whereas methyl and propyl parabens were dominant and accounted for 33% and 65%, respectively. The estimated mean daily intake (EDI) of bisphenol for males and females were 45.94 ng/kg-bw/day and 54.29 ng/kg-bw/day, respectively, while for parabens EDI was 455.35ng/kg-bw/day and 538.14 ng/kg-bw/day for males and females, respectively. Hazard quotient, to evaluate the potential risk of exposure, showed no risk in the studied samples. Even though the EDI results from the Monte-Carlo risk assessment analysis did not exceed the acceptable daily intake, their estrogenic actions cannot be ignored in general populations. The estrogenic activities contributed by parabens and bisphenol A measured by estradiol equivalency quotient (EEQ) ranged from 0.00033–42 pg/mL and 2.3 pg/mL, respectively. Our results revealed higher concentrations of bisphenols and parabens in cow urine distillates; hence, special attention should be given to the quality and safety of cow urine distillates. Moreover, strict guidelines should be enforced for the quality of cow urine distillates.
