preservative used in cosmetics and pharmaceuticals to prevent spoilage
Methylparaben, also known as Methyl 4-hydroxybenzoate or E218, is a type of paraben commonly used as a preservative in cosmetics, pharmaceuticals, and food products. It helps prevent the growth of harmful bacteria and mold, thereby extending the shelf life of these products. While generally considered safe, some concerns have been raised about its potential to cause allergic reactions and its possible link to endocrine disruption.
