Propyl benzoate can be synthesized by the transesterification of methyl benzoate with propanol. [3] Propyl benzoate can also be synthesized by means of Fischer esterification of benzoic acid with propanol.
Less common parabens include isobutylparaben, isopropylparaben, benzylparaben and their sodium salts. The general chemical structure of a paraben is shown at the top right of this page, where R symbolizes an alkyl group such as methyl, ethyl, propyl or butyl. [1]

The severity of effects alcohol may have on a developing fetus depends upon the amount and frequency of alcohol consumed as well as the stage of pregnancy. Rates of alcohol consumption can generally be categorized in one of three ways: heavy drinking (more than 48-60 grams of ethanol/day), moderately high drinking (24-48 grams of ethanol/day ...
The chemical compound isobutyl acetate, also known as 2-methylpropyl ethanoate (IUPAC name) or β-methylpropyl acetate, is a common solvent. It is produced from the esterification of isobutanol with acetic acid. It is used as a solvent for lacquer and nitrocellulose.
Rats exposed to a high concentration of butylparaben during pregnancy gave birth to fewer pups, and pups with malformed reproductive organs. [1] Mice administered butylparaben at 0.01-1% body weight for ten weeks showed a decrease in serum testosterone concentration and in spermatid counts in the seminiferous tubules.
Propylparaben (also spelled propyl paraben) is the n-propyl ester of p-hydroxybenzoic acid. It occurs as a natural substance found in many plants and some insects. Additionally, it can be manufactured synthetically for use in cosmetics, pharmaceuticals, and foods. [ 1 ]
Benzoic acid (/ b ɛ n ˈ z oʊ. ɪ k /) is a white (or colorless) solid organic compound with the formula C 6 H 5 COOH, whose structure consists of a benzene ring (C 6 H 6) with a carboxyl (−C(=O)OH) substituent.
