Perfume and Flavor Materials of Natural Origin, page 143.
Cypress Oil is a pale yellow, pale olive-greenish or almost colorless, mobile liquid.
Cypress Oil has a sweet-balsamic, yet refreshing odor, reminiscent of pine needles oil, templin oil, juniper berry oil, cardamom oil (without the cineole-note), and with a unique dryout of delicate and tenacious sweetness, often compared to that of ambre (labdanum-ambre).
Cypress Oil is frequently submitted to fractionated distillation under vacuum, or simply to a topping-off under vacuum. The high-boiling fractions or, in the case of topping, the residue in the still, usually 40 to 45% of the natural oil, are particularly useful. It is used in perfumes of the ambre-labdanum type in combinations with cistus oil or other labdanum products, delta-methylionone, lavender oil, mandarin oil, sage clary, musk ambrette or macrocyclic musks, styrax products, Moroccan chamomile oil, etc. It is occasionally used as a modifier in pine needle fragrances, in citrus colognes, fougères, chypres, and in the modern-aldehydic type of perfumes.
Distillation is concentrated in the South of France. It is customary to collect and distil the material which is obtained by the annual pruning of the trees, perhaps together with twigs, etc. torn off the trees during the winter mistral, the violent storm.
