Ethylparaben

Synonyms: Ethyl parahydroxybenzoate, Ethyl 4-hydroxybenzoate

Ethylparaben (Ethyl parahydroxybenzoate, Ethyl 4-hydroxybenzoate) is the ethyl ester of p-hydroxybenzoic acid, used as an antifungal preservative and food additive. It is a standardized chemical allergen. The physiologic effect of ethylparaben is by means of Increased Histamine Release, and Cell-mediated Immunity.

Biological Activity

Description Ethylparaben (Ethyl parahydroxybenzoate, Ethyl 4-hydroxybenzoate) is the ethyl ester of p-hydroxybenzoic acid, used as an antifungal preservative and food additive. It is a standardized chemical allergen. The physiologic effect of ethylparaben is by means of Increased Histamine Release, and Cell-mediated Immunity.
In vitro
In vitro Ethylparaben has weak estrogenic and weak anti-androgenic effects in vitro[2].
In Vivo
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].
Animal Research Animal Models Wistar rats
Dosages 100, 200, and 400 mg/kg

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
