Descripción

General description

Benzyl 4-hydroxybenzoate (Paraben, Benzyl Paraben) is an ester of para-hydroxy benzoic acid. It has been added to various cosmetics and personal care products as a preservative. Its quantification in cosmetics has been reported by HPLC methods. Microwave assisted synthesis of benzyl 4-hydroxybenzoate by reaction between (4-hydroxybenzoic) acid and K₂CO₃ in presence of phase transfer catalyst has been reported. It is an endocrine disrupting chemical (EDC). It is a promising candidate for use in pharmaceutical and personal care products. Its visible-light assisted photosensitized degradation in homogeneous aqueous solution of 4,4′,4′′,4′′′-(porphine-5,10,15,20-tetrayl)tetrakis(benzenesulphonic acid) has been investigated.

Application

Benzyl 4-hydroxybenzoate may be used as internal standard for the simultaneous analysis of non-steroidal anti-inflammatory drugs in human plasma and urine using microextraction by packed sorbent and HPLC method. It may be employed as internal standard for the HPLC determination of rutin, kaempferol, genistein, formononetin and biochanin A in Ononis spinosu roots.
