Ethylparaben is produced naturally and found in several fruits and insects, where it acts as an antimicrobial agent. Ethylparaben is mainly used as antiseptics in cosmetics, food and medicine (E number E214). It is also can be used as feed preservatives and antiseptic for bacteria. Ethylparaben is readily absorbed from the gastrointestinal tract or through the skin. It is hydrolyzed to p-hydroxybenzoic acid and rapidly excreted in urine without accumulating in the body. Under the Federal Food, Drug, and Cosmetic Act (FD&C Act), cosmetic products and ingredients, other than color additives, do not need FDA approval before they go on the market. Broad concentration ranges reported in each product category in 1981 were < 0.1% and > 0.1% to 1%. Studies show the in vivo estrogenicity of MP and EP at human exposure levels, and indicate that populations exposed to large amounts of MP and EP may have a high burden of estrogenicity-related diseases.

CNS Activity

Curator's Comment: Known to be CNS penetrant in dog. Human data not available. After ethyl paraben is intravenously infused into the dog, unhydrolyzed ethyl paraben is found only in the brain.

In Vivo Use Guide
Curator's Comment: Ethyl paraben was mixed with the standard CE-2 powdered Wistar rats diet.
103 mg/kg/day for the 0.1% ethyl paraben
Route of Administration: Oral
The antimicrobial activities of ethylparaben on R. solanacearum, S. typhimurium, E. coli, F. oxysporum, A. niger, F. solani and F. moniliforme were investigated. In the test, the antibacterial activities were assayed using 20 U/mL streptomycin sulfate as a control. The antifungal activities were assayed using 100 mg/mL hygromycin as control. The 50 mg/mL crude antimicrobial extract dissolved with DMSO was poured into the wells and one well was used as a control. For antifungal activity, the plates were incubated at 28 °C for 2 days. For antibacterial activity, the plates were incubated at 30 °C for 24 h. Ethylparaben was found to inhibit these seven different types of microbes to different extents.
