Caprylaldehyde

Caprylaldehyde also known as Octanal, or aldehyde C8, belongs to the class of organic compounds known as medium-chain aldehydes, which are aldehydes with a chain length between 6 and 12 carbon atoms. Octanal is a fatty aldehyde lipid molecule. It is produced by hydroformylation of heptene and the dehydrogenation of 1-octanol (  doi:10.1002/14356007.a01_321.pub2 ). Caprylaldehyde is very hydrophobic, practically insoluble in water, and relatively neutral. Octanal is colorless or lightly yellow tinged fragrant liquid with a fruit-like (green, orange, rose, coconut) odor and a waxy, citrus or fruity taste. It occurs naturally in citrus (such as blood orange, lime, mandarin, orange) and other oils from bergamot, blood orange, lime, lemon, grapefruit, orange peel and yuzu peel. Caprylaldehyde is one of the simple aldehydes found in cannabis plants (PMID:6991645) as well as carrot root, celery shoot and leaf, ceylon cinnamon leaf, rose and witch hazel leaf ( http://www.thegoodscentscompany.com/data/rw1000251.html#tooccur). It is used commercially as a component in perfumes and in flavor production for the food industry. It is also used as a raw material for surfactants, for conditioners, for disinfectants and for plasticizers. It is used as an oil base for lubricants of synthetic resin and for emulsifiers of emulsion polymerization. Octanal is also used as a material for creams and ointments. Additionally, octanal is used as a masking agent, a perfuming agent and a viscosity controlling agent in the food and cosmetic industry.
