Methylparaben is a 4-hydroxybenzoate ester resulting from the formal condensation of the carboxy group of 4-hydroxybenzoic acid with methanol. It is the most frequently used antimicrobial preservative in cosmetics. It occurs naturally in several fruits, particularly in blueberries. It has a role as a plant metabolite, an antimicrobial food preservative, a neuroprotective agent and an antifungal agent. Methylparaben is used in allergenic testing. Methylparaben is a Standardized Chemical Allergen. The physiologic effect of methylparaben is by means of Increased Histamine Release, and Cell-mediated Immunity. Methylparaben is a natural product found in Zanthoxylum beecheyanum, Rhizophora apiculata, and other organisms with data available. Methylparaben is found in alcoholic beverages. Methylparaben is an antimicrobial agent, preservative, flavouring agent. Methylparaben is a constituent of cloudberry, yellow passion fruit, white wine, botrytised wine and Bourbon vanilla. Methylparaben has been shown to exhibit anti-microbial function Methylparaben belongs to the family of Hydroxybenzoic Acid Derivatives. These are compounds containing an hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxylic acid. (A3204).

Methylparaben, also known as methyl 4-hydroxybenzoate or p-carbomethoxyphenol, belongs to the class of organic compounds known as p-hydroxybenzoic acid alkyl esters. These are aromatic compounds containing a benzoic acid, which is esterified with an alkyl group and para-substituted with a hydroxyl group. Methylparaben is an antimicrobial agent, preservative, and flavouring agent. methylparaben has been detected, but not quantified, in a few different foods, such as alcoholic beverages, saffrons, and fruits (particularly blueberries). It is also a constituent of cloudberry, yellow passion fruit, white wine, botrytized wine, and Bourbon vanilla. Methylparaben is the most frequently used antimicrobial preservative in cosmetics.
