Methylparaben, a chemical compound with the CAS number 99-76-3, is a versatile ingredient recognized primarily for its efficacy as an antimicrobial preservative. Its chemical structure, molecular formula C8H8O3, and molecular weight of 152.15 g/mol are fundamental to its properties. As a manufacturer and supplier of this essential chemical, understanding its attributes is key to appreciating its widespread use in industries ranging from cosmetics and pharmaceuticals to food and personal care products.

The physical appearance of Methylparaben is typically a white crystalline powder or colorless crystals. It possesses a faint, characteristic odor and a slightly burning taste. Crucially, it exhibits good solubility in alcohol and acetone, and is slightly soluble in water. This solubility profile makes it adaptable for incorporation into a wide array of aqueous and non-aqueous formulations. Furthermore, Methylparaben demonstrates excellent stability across a broad pH range (4-8), a trait that significantly enhances its utility as a preservative in products with varying chemical compositions.

The primary application of Methylparaben is its role as a preservative. It effectively inhibits the growth of bacteria, yeasts, and molds, which are common causes of product spoilage. This property makes it invaluable for extending the shelf life of cosmetics, skincare products, haircare items, pharmaceuticals, and even certain food products (where it is designated as E218). Its low toxicity at recommended usage levels, typically between 0.1% and 0.5%, further solidifies its position as a preferred preservative in many industries.

The manufacturing process for Methylparaben typically involves the esterification of p-hydroxybenzoic acid with methanol. This chemical synthesis is carried out under controlled conditions to ensure high purity and consistent quality.
