Chemical Properties
| 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]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarify
