Description | Ethylparaben (Ethyl parahydroxybenzoate) is a Standardized Chemical Allergen. The physiologic effect of ethylparaben is by means of Increased Histamine Release, and Cell-mediated Immunity. |
In vitro | Ethylparaben has weak estrogenic and weak anti-androgenic effects in vitro[2]. |
In vivo | In vivo studies indicate that ethylparaben has estrogenic effects in vivo in immature and ovariotectomized mice. A study on fetal exposure to ethylparaben revealed no changes in male anogenital distance and no changes of fetal testosterone production, but changes in gene expression levels pointed to subtle endocrine disrupting effects. A limited study in young male rats found no adverse effects, although tendencies to lower sperm counts are seen. Ethylparaben causes vitellogenin induction in fish[2]. |
