Metabolite Identification
Common NamePropylparaben
DescriptionPropylparaben, also known as propyl chemosept or propyl parasept, 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. Propylparaben is a sweet, burnt, and hawthorn tasting compound. Propylparaben is a potentially toxic compound. Propylparaben is an antimicrobial agent, preservative, flavouring agent.
