Organoleptic Properties

Odor Type: Woody
dry, sawdust, woody, powdery, amber, sandalwood
Odor strength medium , recommend smelling in a 10.00 % solution or less
Substantivity > 600 hour(s) at 100.00 %
Luebke, William tgsc, (1987) At 100.00 %. dry sawdust woody powdery amber sandalwood
Stable in: body lotion (good), shampoo (very good), soap (very good), ap roll-on (very good), powder (very good), cleaner citric (good), cleaner apc (very good), bleach (poor). Highly diffusive, powdery-woody, with notes of ambergris aroma chemical
This super dry substantive ambery/ woody molecule can be used to accent the top, middle and dry down notes in men’s and woman’s fragrances. Normally used as a 10% solution. A woody note that gives top and middle note effects in addition to its long-lasting and substantive properties. Should be tried wherever a woody character is required but does require careful blending and dosing. Extremely powerful woody and animal amber note. NORLIMBANOL™ has a dry woody note in the patchouli direction
General comment WOODY, ANIMAL, AMBER, POWERFUL
Description from Firmenich: “Extremely powerful woody and animal amber note. NORLIMBANOL™ has a dry woody note in the patchouli direction”. As described by Chandler Burr: “Norlimbanol is one of the most amazing scents around, a genius molecule that should be worth its weight in gold; Norlimbanol gives you, quite simply, the smell of extreme dryness, absolute desiccation, and if you smell it, you’ll understand that instantly—the molecule is, by itself, a multi-sensory Disney ride.” According to the analysis of Scent and Chemistry, Norlimbanol is featured in extreme overdose in a number of Alessandro Gualtieri’s creations, including around 5% in Viride (Orto Parisi, 2014) and around 11% in Boccanera (Orto Parisi, 2014). Dry-wood, driftwood, animal, amber
Recently released by IFF Karmawood shares a CAS number with the very similar Norlimbanol, though it isn’t quite as powerful it has the advantage of being somewhat cheaper (depending on quantity less than half the price). Although it the same molecule and produced to a similar purity while Norlimbanol is 95% the trans isomer, Karmawood is 65%, which also makes it a bit easier to melt if it solidifies. Dry-wood, driftwood, animal, amber, sandalwood
Purest key olfactive isomer available on the market, NORLIMBANOL ® DEXTRO is a breakthrough innovative molecule. Powerful dry woody and ambery note
