Definition
ChEBI: Benzyl parahydroxybenzoate is a benzoate ester and a benzyl ester.
Allgemeine Beschreibung
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.
Flammability and Explosibility
Not classified
Kontakt-Allergie
This substance is one of the parabens family. Parabens are esters formed by p-hydroxybenzoic acid and an alcohol. They are largely used as biocides in cosmetics and toiletries, medicaments, or food. They have synergistic power with other biocides. Parabens can induce allergic contact dermatitis, mainly in chronic dermatitis and wounded skin.
