Ethylparaben

Description

Ethylparaben is a widely used preservative in skincare, cosmetics, and pharmaceutical products. This synthetic compound belongs to the paraben family and is derived from para-hydroxybenzoic acid. Its primary function is to prevent the growth of harmful microorganisms, including bacteria and fungi, thus extending the shelf life of products and ensuring their safety for consumer use.

With a molecular formula of C9H10O3, ethylparaben is a white crystalline powder that is soluble in water and various organic solvents. It is effective at low concentrations, typically used at levels between 0.01% and 0.3% in cosmetic formulations. Ethylparaben exhibits broad-spectrum antimicrobial activity and is particularly effective against gram-positive bacteria.

While parabens have been subject to controversy regarding their potential estrogenic effects, multiple regulatory bodies, including the FDA and EU Scientific Committee on Consumer Safety, have deemed ethylparaben safe for use in cosmetics at current concentration levels. It is rapidly metabolized and excreted from the body, with no evidence of bioaccumulation.

Ethylparaben's stability across a wide pH range and compatibility with other ingredients make it a versatile choice for formulators seeking effective preservation in various product types.
