BMF 64 - Parabens

Parabens are a class of chemicals widely used as preservatives in personal care, cosmetic, pharmaceutical and food products since the 1930s. Parabens are esters of para-hydroxybenzoic acid (Fig.1) with methylparaben, ethylparaben, propylparaben, and butylparaben being most commonly used. Parabens and their salts are used for antimicrobial properties. They are detected in waste water, rivers, soil and house dust, hence human exposure is ubiquitous throughout life. Due to their omnipresent nature parabens are usually detected in human tissues and fluid samples although they are excreted relatively quickly. Although parabens are still widely considered to be safe, health concerns have been raised since studies have shown that parabens are found in breast tissue from patients with breast cancer.


Chiron is happy to offer a variety of parabens including internal standards. Native reference materials are available as neat material, or as a solution in methanol. Internal standards are available as a solution in methanol.
