Metabolite Identification
Common NameMethylparaben
DescriptionMethylparaben, 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.
