Propylparaben is a chemical compound commonly used as a preservative in cosmetics, personal care products, and some food items. It helps prevent the growth of harmful bacteria and mold, extending the shelf life of these products. Propylparaben is part of a larger group of compounds known as parabens, which are widely used for their antimicrobial properties. Although considered safe in low concentrations, some studies have raised concerns about potential health effects, leading to ongoing debates about its use. Regulatory agencies, such as the U.S. Food and Drug Administration (FDA) and the European Commission, continue to evaluate its safety in consumer products.
