Piperonal is an aromatic aldehyde. It is an extract of sassafras and is commonly used in the manufacture of perfumes and soaps. It is a derivative of safrole, which is a naturally-occurring aromatic that is obtained from botanicals such as cinamomum petrophilium and sassafras albidum.

In spite of their antibacterial and antiviral properties, all safroles are banned for use in food because they are known carcinogens and hepatoxins (toxic to the liver). They are widely and commonly used in the perfume industry and are increasing in use as a preservative component in cosmetics.
