Propyl 4-Hydroxybenzoate (Propyl Paraben) is an ester of p-hydroxybenzoic acid, commonly used as a preservative in cosmetics, personal care products, and pharmaceuticals. It effectively inhibits the growth of bacteria, fungi, and yeast, prolonging the shelf life of formulations. This compound is favored for its antimicrobial properties and low toxicity at typical concentrations. However, due to concerns over potential endocrine-disrupting effects, its use is being carefully regulated in various markets, particularly in the European Union and North America.
