Description and usage notes:

Very useful, fresh, woody top-to-middle note. An original IFF material who describe it as: “Sweet, rich and woody. This material blends well with ionones and enriches the odour quality of fragrances for functional products”.  

Arctander suggests it is: “Widely used in perfumery along with the Ionone, Cedarwood products, floral and non-floral perfume chemicals, a very verstile perfume material for soap and other low-cost fragrances, where volume is required.  Generally as a blender / modifier in countless types of fragrances, from Pine to Rose, from woody to floral, it is one of the most successful perfume chemicals of the last few decades.” 

Bedoukian, writing some 25 years later suggests that “As the price of such oils as vetiver and sandalwood goes up, this relatively inexpensive ester is becoming increasingly attractive to the perfume industry.”  He goes on to tell use that “It imparts a woody, balsamic odor to soap and detergent perfumes and acts as a blending agent in chemical formulations.  It is stable and non-discoloring” 

Calkin & Jellinek, in their discussion of the 1966 fine fragrance Fidji tell us that: “The synthesis of Vertofix (acetyl cedrene) from cedarwood in the early 1960s marked a major step forward in perfumery chemistry, providing perfumers with a fine woody material at a reasonable price, which could be used not only to replace the very much more expensive vetiver derivatives but also had an excellent performance in many functional products such as soaps and shampoos. It is interesting also to find in Fidji a small amount of PTBCHA (Vertenex), another relatively new material at that time, and one more frequently associated with functional products. Here it acts as a link between the woody notes and the fresh green top note.”
