Ethylparaben

Ethylparaben is the ethyl ester of para-hydroxybenzoic acid, belonging to the paraben family of preservatives alongside methylparaben (E218) and sodium methylparaben (E219). It prevents mould, yeast, and bacterial growth in foods by disrupting microbial cell membranes. EU use is restricted to specific food categories where its antimicrobial function is most needed, such as certain processed foods and beverages.

JECFA's ADI is 10 mg per kilogram body weight per day, evaluated in 1996 as a group ADI covering all hydroxybenzoate esters and their salts. This is the same group ADI applied to E218 and E219. Ethylparaben shares the weak oestrogenic activity identified for other parabens in in vitro assays — it can bind oestrogen receptors at high concentrations. Regulatory bodies consider this activity insufficient to pose a risk at food additive exposures, though the evidence base continues to be monitored.

Ethylparaben is approved in the EU at restricted levels. It is less commonly used than methylparaben and is not approved as a food preservative in the US. Consumers concerned about paraben exposure from food — particularly given the broader debate about parabens in cosmetics and personal care products — should note that dietary exposure from food additives is generally much lower than from topical cosmetic use. For healthy adults, food additive use of E214 presents no established safety concern at regulated levels.
