Function: 

Colorless to light yellow liquid with aroma of lemon, citronella and rose. To d-, l- and dl- three optical bodies exist. D-citronellal exists in a large amount in essential oils, and is the main component of citronella oil and eucalyptus oil. Its boiling point is 203-204°C, its relative density (d420) is 0.8510, its optical rotation [α] D18+10°18′, its refractive index (D20) 1.4467. Lemongrass oil contains l-citronellal, with a boiling point of 206°C, a relative density (d2525) of 0.8567, a refractive index (nD20) of 1.4491, and an optical rotation [α] D-3°. It is easy to cyclize into menthol in acidic medium. The flash point is 77°C. Soluble in ethanol and most non-volatile oils, slightly soluble in volatile oils and propylene glycol, insoluble in glycerin and water..

Application: 

  1. Citronellal is mainly used as a raw material for synthesizing citronellol, hydroxycitronellal, menthol and the like. It can be used in a small amount of low-grade lemon, cologne, magnolia, lily of the valley, honey and fragrance, mainly because it has the effect of grass green gas.
  2. Citronellal is rarely used in high-grade flavors, but is often used in inexpensive soap flavors. Mainly used in the manufacture of vanillyl alcohol and hydroxy citronella vinegar. Synthetic menthol is produced from the menthol brain. Among them, hydroxycitronellal is one of the most valuable spices.
  3. Citronellal is used to prepare flavors with a rich lemon, lemon grass rose-like aroma
  4. Citronellal is widely used as a fixative, a complexing agent and a modifier in cosmetic perfumes; it is also a flavoring agent for beverages and foods. It can be prepared from citronella oil or acetylated and oxidized from isoeugenol.
