Methylparaben is a type of preservative commonly used 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. Methylparaben is part of a larger group of compounds known as parabens, which are widely used for their antimicrobial properties. Although methylparaben is generally recognized as safe by regulatory agencies like the U.S. Food and Drug Administration (FDA), some consumers prefer to avoid it due to concerns about potential health effects. Research continues to explore the safety and impact of methylparaben and other parabens on human health and the environment.
