Guest guest Posted November 6, 2002 Report Share Posted November 6, 2002 Hi , East Indian sandalwood produced from the roots and heartwood of has a fairly consistent analysis profile. Most of us take the criteria of the famous Indian chemist, Verghese, as providing the acceptable composition guidelines. He established the normal range for santalols in the EI oil. It is known however that (+)-(Z)-a-santalol has only a weak odour, and that (-)-(Z)-b-santalol contributes more to the odour profile. The oxidative degradation products of these alcohols, such as (+)-(E)-a-santalal, are also important. By aroma dilution analysis (that is by diluting the odour down until we can only perceive one or two odourants), we can show that nor-a-trans-bergamotenone in spite of its presence being approx. 0.01%, is also a very strong odour impact material in sandalwood EI. By comparison we can show that Indonesian sandalwood oil scores comparitively poorer in impact, radiance etc, thus confirming master perfumers opinions over the years. However there are some tricks of the trade. One is to artificially oxidise the sandalwood oil to produce substances like santalal above. However in spite of the widespread view that I have seen on other AT lists, that the longer you keep sandalwood oil the better it gets, sandalwood oil can go " over the hill " after a few years, developing sour notes and rancidity. It often the case therefore that artificially oxidised Indonesian sandalwood oils will not keep as long. But basicaly they lack the " creaminess " of Sandalwood oil, which may be something to do with the bergaamotenone content, as this iimparts milky and nutty qualities to the oil. Sandalwood chips that I have seen ex India (sold to China) are the exhausted chips ex distillation. They have the characteristic white outer surfaces you remark on. Sandalwood sawdust is available also, and of course much used by joss-stick makers, but often contaminated with the sawdust of other species of tree. The supplies of Indonesian sandalwood have only recently dried up in the past few months. Sandalwood oil EI is still available but very short, as I said topping $600 a kilo and still moving up. No-one expects it to be freely available in future. . Australian Sandalwood extracts, are produced we believe by solvent extraction followed by co-distillation, or by other means (my website will be revealing further details) are of course being marketed from another threatened species of sandalwood. Its odour composition and properties differ from East Indian Sandalwood, for which there is no replacement.

Guest guest Posted November 6, 2002 Report Share Posted November 6, 2002 Tony, I don't want to continue a long debate, but frankly I don't buy everything you are saying. 1. I don't buy that you can even compare accurately the woods by analyzing the oils. Every distillation ends up different and I can manipulate the same oil greatly using the exact same source material. 2. I don't think you can show a legitimate " Baseline " for comparison, no matter how famous the chemist. 3. When you talk about comparisons, do you have any strick controls assuring a reasonable comparison, e.g. How old were the trees chosen for the experiment. How were the samples noted and controlled (what percentage of what grade root, compared to what percentage of base heartwood? 4. Everything you write slants to Indonesian or Austrailan tampering, which reads to me like a vested interest in pushing IA Sandalwood. That may not be the case, but that is the way I read it, especially since you don't seem to mention the possibility of Indian tampering at all, and the Indians are the masters of tampering and adulteration. I wouldn't try to deny that because I can pull up FDA cases against Indian companies and easily demonstrate that. Some top companies at that! don't have me pulling those covers or half the people in this business will be coming after me, sending me email viruses, and poking pins in voodoo dolls. Are far as natural Sandalwood going Rancid, I've never seen that happen when ther WASN'T a synthetic involved, by I have seen adultered Sandalwoods go rancid.

I didnt say you could compare the woods - I was comparing the oils from the woods, and I am only interested in complete oils, not fractions. The oils have been the subject of a very large number of analytical and odour investigations over the years - I discuss eleven or so oils in the first edition of my book, and I supply appropriate references. This is expanded in the second edition. Comparison of the odour of the woods would require different analytical techniques - but this is not routinely done to my knowledge. > 2.

Lets just say that my experience is different. > 3.

The effect of tree age, part of the tree etc. are known variables to these studies. As backgound, the oils from any individual oil-bearing tree species are always slightly different tree to tree. Individual rosewood trees for example give some oils richer in laevo linalol, some oils richer in dextro linalol, the oils thertefore smell different. The allowances for-, the limits to- and the effects of natural variability is built-in to essential oil studies, so we know what the norms are and what the typical range looks like for any given property. However what I was originally talking about are character compounds, which are taken as indicators of quality. > 4.

Over the years you get to know who you can trust and who you cannot. There is a core of us old timers who swap details about known crooks in this business. In some cases this is highly detailed and documented. > Are far as natural Sandalwood going Rancid, I've never seen that > happen when ther WASN'T a synthetic involved, by I have seen > adultered Sandalwoods go rancid.

Now, I was speaking of the woods originally when you commented on the quality difference, wasn't I? Anyway, in order to analyze the true potential of the oil, I think you need to collect the wood yourself, distill it yourself, and analyze it yourself. You may be able to get some kind of picture by analyzing the oils coming from both, but that doesn't tell you if the problem is an inherent difference in the trees, or coming from the production side. Known crooks hey! Oldtimers????? To my friends at Baieido, I'm sure you seem anything but an oldtimer, since the family business dates back to at least 1657. And they've been in those forests many times. They are the oldest aromatics trader in the world to my knowledge, and we don't even know how old, because in those days, the Japanese didn't have last names. And they took their father's name, and the name of their trade when they took over. Jinkoya Sakubei took that name in 1657 when he changed the business to specialize in aloeswood. Before that he was Yamatoya (Medicinal Herb Wholesaler) Sakubei and we don't know how many Yamatoya Sakubei's there were because the records were destroyed in WWII. So, Tony, I think I get some pretty good info, and in the last four years, Baieido has not contradicted one thing they've ever told me, and I've yet to find their information anything less than perfect. On occasion they couldn't answer a question and would contact someone like Professor Yoneda (who is the only person in modern times allowed to take a sample from Ranjatai) or another Japanese expert and get the answer. In contrast to the " Oltimers " in the EO industry whose stories seem to drift on the wind, contradict each other daily, and apparently keep the entire industry in a state of confusion and paranoia. Ask anyone and they will tell you they are the only ones that have " real " . . . Later, Tony. Quote Link to comment Share on other sites More sharing options...
