New Woody and Ambery Notes from Cedarwood and Turpentine Oil

Abstract

The development of a new product in the chemical industry is still driven by needs like technical properties, price/performance ratio, biodegradability, or product safety. However, in terms of improving more and more on ecological criteria, summarized under such catchphrases as sustainable development or green chemistry, another important aspect is to use renewable resources as starting materials. This is not significantly new in fragrance chemistry, and there are a lot of raw materials in the perfume oils that are derived from molecules of renewable resources. Two commonly used materials are: longifolene (from turpentine oil) and cedrene (from cedarwood oil). These compounds are very suitable for the synthesis of woody and ambery notes, and even though it seemed that all possibilities were exhausted, it is actually still feasible to discover new molecules with excellent olfactory properties such as Ambrocenide (50a), which is available in three steps from a-cedrene. Some of these molecules will be treated in this review, both with respect to synthesis as well as structural and sensory aspects.

Antimicrobial activity of sugar beet lignocellulose films containing tung oil and cedarwood essential oil

“…Span 80 is a non-ionic surfactant also known as sorbitan monooleate or oleate with band at 3300-2900 cm -1 from hydroxyl, methylene and methyl CH stretching. The addition of CWO or tung oil into SBL film resulted in the appearance of two new bands at 1741 and 1463 cm -1 from carbonyl groups (C=O) associated with esters, carboxylic, carboxylates and double bonds from polyunsaturated palmitic, stearic acid, linoleic fatty components of tung oil (Pereda et al 2010;Trumbo and Mote 2001); sesquiterpenes alcohol, including cedrol, widdrol, sesquiterpenes such as cedrene, thujopsene from CWO (Kamatou et al 2010;Panten et al 2004). The increase in intensity of bands at 2927, 2866, 1463, and 1236 cm -1 from methylene and methyl groups was observed with increase of the amount of oils, clearly confirming their origin from eleostearic and oleic acid from tung oil as well as CWO terpenes.…”
