Perfume and Flavor Chemicals, page 1144.
Colorless mobile liquid.
Practically insoluble in water, soluble in alcohol (not in diluted alcohol) and miscible with most perfume oils. Almost insoluble in Propylene glycol and Glycerin.
Its odor is warm-resinous, refreshing Pine-like, but lower grades of this material may carry more pronounced 'Turpentine'-like odor, 'Rosin'-odor or even herbaceous-aromatic odor (common feature of autoxidized alpha-Pinene).
alpha-Pinene has a more balsamic taste, while beta-Pinene, less suitable for flavors, has a dry-woody character.
The material as such is not a very important perfume chemical. Apart from use in artificial Pine needle oil or fragrance, it will only be a minor ingredient in other compositions: artificial Lemon, Bergamot, Nutmeg, Geranium, Lavandin, etc. and for these particular purposes, the alpha-Pinene must be of high olfactory purity.
The title material is also used in flavor compositions, partly as ingredient in artificial Lemon and Nutmeg oils, partly as component of such type flavors. The concentration in the finished product will be about 15 to 150 ppm.
Produced by fractionation of Sulfate Turpentine or neutral Turpentine. It has also been made by isomerization of beta-Pinene.
