It is understood that n-decanol (decyl alcohol) has a waxy, sweet, floral, fruity aroma, and is a mixture of citronellol orris root oil. Similar colorless transparent liquid. Decanol is obtained by reducing coconut oil fatty acids. It can also be obtained by hydrolysis and separation of ethylene after controlled polymerization. Naturally occurring: Found in sweet orange oil, neroli oil, apricot flower oil, and sunflower oil.
