E215 - Sodium ethyl p-hydroxybenzoate

Origin

Sodium ethyl p-hydroxybenzoate, also known as ethylparaben sodium, is a synthetic compound derived from ethylparaben. Ethylparaben itself is an ester of p-hydroxybenzoic acid. The sodium salt is created to improve water solubility, making it easier to incorporate into various formulations.

Usage

This additive functions primarily as a preservative. It inhibits the growth of molds, yeasts, and bacteria, thereby extending the shelf life of food and cosmetic products. It is used in a variety of applications, including baked goods, beverages, jams, jellies, sauces, and processed fruits and vegetables. It is also used in cosmetics, pharmaceuticals, and personal care products. The typical concentration used varies depending on the application and regulatory limits, but it is generally used at levels below 0.1%.

Side Effects

Parabens, including ethylparaben, have been studied for their potential estrogenic effects. While the estrogenic activity of ethylparaben is considered weak compared to natural estrogens, concerns have been raised about potential endocrine disruption, especially with long-term exposure to high concentrations. Some individuals may experience allergic reactions to parabens, manifesting as skin irritation, contact dermatitis, or other hypersensitivity reactions. Regulatory bodies like the European Food Safety Authority (EFSA) and the Food and Drug Administration (FDA) have evaluated the safety of parabens and established acceptable daily intakes (ADIs) or usage limits to minimize potential risks. The ADI for parabens (including methyl-, ethyl-, and propylparabens) is set at a group ADI of 0-10 mg/kg bw per day by EFSA. It's important to note that individual sensitivity to parabens can vary.

Regulatory Status

Sodium ethyl p-hydroxybenzoate is permitted for use as a food preservative in many countries, including those in the European Union, where it is assigned the E number E215. Regulations specify the maximum permitted levels in different food categories. The FDA also regulates its use in the United States, specifying acceptable uses and concentrations. Compliance with these regulations is essential to ensure consumer safety.
