Guaiacwood (Reconstitution)


Erroneously called guaiacwood concrete, this oil is steam distilled, occasionally steam-and-water distilled from the wood of Bulnesia Sarmienti, a wild-growing tree from the jungles of Paraguay and Argentina.

Guaiacwood Oil is a soft or semi-solid mass, yellowish to greenish yellow or pale amber in color. When melted, it may stay supercooled and liquid for a long time. Once again, we meet a product which quite frequently presents odor types not reported in literature: opart from its delicately sweet, rosy-woody odor which is often referred to as “tearose-like”, the oi I may have a “smoked ham” odor which is definitely unwanted, but not uncommon. It is conceivable that this odor, which was never reported prior to World War II, occurs in oils which have been “forced” during the distillation through the addition of mineral acid (sulfuric, etc.) to the chopped, wet wood in the still. This increases the yield of oil, but it also creates a hazard of spot-burning of the woodchips. Similar to amyris, the age of the wood prior to distillation also has some influence upon the odor of the oil. The main constituent of guaiac wood oil is called Guaiol (“gaiol”) This sesquiterpene alcohol can be acetylated to the so-called Guaiyl Acetate.


Guaiacwood NNO blends well with Iinalool, nerol, geraniol, terpineol, oak moss, ionones, orris products, spice oils, etc.
