Ethylparaben / Ethyl 4-hydroxybenzoate

Ethylparaben, scientifically known as Ethyl 4-hydroxybenzoate or 4-Hydroxybenzoesäureethylester, is an ethyl ester derived from 4-Hydroxybenzoic acid and is a member of the Parabens family. This compound is widely used in cosmetics and personal care products for its preservative properties. Ethylparaben is characterized by its melting point at 115.8°C and a melting enthalpy of 158.6 J·g−1, indicating its stability under specific conditions. Moreover, its solubility is low in water but high in most organic solvents, making it an ideal preservative choice for various products.

Effects in Cosmetics

Ethylparaben has multiple effects and applications, some of which include:

Serving as a preservative to extend product shelf life.
Preventing microbial growth, such as bacteria and fungi, in cosmetics.
Its good solubility allows easy incorporation into various formulations.

The use in food

Used as an E 214 additive to prevent food spoilage and extend shelf life.
In the food industry, its sodium salt form (E 215) is commonly used for better solubility.


Ethylparaben is mainly obtained through chemical synthesis, involving the esterification of 4-Hydroxybenzoic acid with ethanol.
Its production process involves precise temperature and pressure control to ensure product quality and purity.

Globally Harmonized System of Classification and Labelling of Chemicals 


Ethylparaben has been approved by the European Food Safety Authority (EFSA) as a food additive (E 214), but its use must comply with specific concentration limits.
Although considered safe for widespread use, it may cause allergic reactions in certain populations, especially pseudoallergic reactions in asthmatics.
