Methyl Paraben Extra Pure

Whatsapp Order

Methyl Paraben Extra Pure is a high-purity chemical widely used as a preservative in pharmaceuticals, cosmetics, personal care products, and food applications. It is valued for its strong antimicrobial and antifungal properties, helping to extend the shelf life of various formulations by preventing the growth of bacteria and mold. In laboratories, it is commonly employed in microbiological media and analytical standards. Its excellent stability across a broad pH range, combined with low toxicity and high efficacy even at low concentrations, makes it a preferred choice in sensitive applications. This extra pure grade ensures consistent quality and performance for critical uses.
