Safety Information
(-)-MYRTENOL Usage And Synthesis
| Chemical Properties | Myrtenol has a camphoraceous, minty, medicinal, woody odor |
| Occurrence | Reported found in cranberry, bilberry, blackberry, raspberry, strawberry, Virginia tobacco, mandarin and limepeel oil, melon, ginger, peppermint and Scotch spearmint oil, pepper, parsley, Gruyere cheese, hop oil, Bourbon vanilla, cognac, tea,laurel, myrtle leaf, myrtle oil, buchu oil, lemon balm, lamb’s lettuce, Roman chamomile oil, eucalyptus oil and mastic gum and leaf oil. |
| Uses | Myrtenol (cas# 515-00-4) is used in mosquito attractant compositions. |
| Application | Myrtenol is an excellent blender-modifier for Lavender, Citrus and Bay type fragrances, for Men’s Colognes, etc. and it gives attractive notes to Chypre or Oriental perfumes. The acetate, which represents the sweetness of the Myrtle oil, is also commercially available and is produced synthetically. |
| Production Methods | Myrtenol is produced from alpha- or beta-Pinene 1) by oxidation with Selenium oxide. 2) by chlorination via the acetate to the alcohol. Myrtenal is a by-product in this process. |
| Preparation | Can be obtained in d,l-form from α-pinene with SeO2 in ethanol. |
| Aroma threshold values | Detection: 7 ppb |
| Taste threshold values | Taste characteristics at 50 ppm: cooling, minty, camphoraceous, green mentholic spice with a medicinal nuance. |
