Pure PMD is synthesized for commercial production from synthetic citronellal. Lemon grass oil contains 65-85% citral in addition to myrcene, citronellal, citronellol, and geraniol. Polymer-stabilized nanoparticles can also be used for the hydrogenation of cinnamaldehyde and citronellal. Additional rearrangements and oxidations provide compounds such as citral, citronellal, citronellol, linalool, and many others. Another research shows that citronellal has strong antifungal qualities. Its flavour comes from citronellal (24%), geranial (16%), linalyl acetate (12%) and caryophyllene (12%). Citronellal is also converted to rose oxide and menthol.
