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