Notes:
Found in essential oils of ylang-ylang, clary sage, California orange, bitter orange and others. Flavouring agent Heptanal or heptanaldehyde is an alkyl aldehyde with a strong fruity odor which is used as an ingredient in cosmetics, perfumes, and flavors. It can be obtained from castor oil by distillation under reduced pressure. Industrially, it is used in the manufacture of 1-heptanol and ethyl heptanoate.
