Methylparaben

Description:
Methylparaben, with the CAS number 99-76-3, is a widely used preservative in cosmetics, pharmaceuticals, and food products. It is a member of the paraben family, which are esters of p-hydroxybenzoic acid. Methylparaben appears as a white crystalline powder or a colorless liquid and is soluble in alcohol and propylene glycol, but only slightly soluble in water. Its chemical formula is C8H8O3, and it has a molecular weight of approximately 152.15 g/mol. Methylparaben is known for its antimicrobial properties, effectively inhibiting the growth of bacteria and fungi, which helps extend the shelf life of products. It is generally recognized as safe by regulatory agencies when used within recommended concentrations. However, there has been some controversy regarding its potential endocrine-disrupting effects, leading to ongoing research and discussions about its safety in consumer products. Overall, methylparaben remains a popular choice for preserving various formulations due to its effectiveness and low toxicity profile.
