What Ethylparaben does

Protects formulas from mold and bacteria
Helps products stay fresh on shelves
Works in water-based and creamy formulas

Ethylparaben is made by reacting para-hydroxybenzoic acid with ethanol, a common process called esterification. It is one of several parabens, a family of preservatives that have been used in cosmetics for many decades.

Formulators use it because it helps guard water-based products against mold, yeast and bacteria. It is usually used in small amounts, often alongside other preservatives, and it adds little scent or color. Its feel on skin is light, so it usually does not change how a concealer or lotion feels.
