Vanillin

Vanillin’s organoleptic impression is surprising in view of its chemical nature. It can be considered as a substituted benzaldehyde, yet it lacks an almond impression. When viewed as a substantial phenol, it displays none of the expected carbolic note. It is so unique that it may be safe to say it represents an individual odor class—vanilla!

Thymol

An aroma chemical profile, thymol. Natural thymol that has been isolated from essential oil invariably is tinged with notes of carvacrol, a material that is described as being more dry-medicinal-phenol-tarry than thymol itself. Very little, if any, natural thymol is produced today as its price would be about tenfold higher than the synthetic product available.

The process began in the 2000s and in the last two years Solvay scientists revisited the process, focused on increasing yields and improving the separation stage.

More Perfume Materiak from Isoprene

We should all realize that the new Toxic Substances Control Act, which Congress is about to pass, will increase considerably the cost of developing new aroma chemicals. The new law may reduce the number of such chemicals drastically. Closer cooperation between the fragrance and the aroma chemical industries will now be even more important in order to maintain a healthy level of innovation in areas of mutual interest.

Chemical Characterization of Vanilla pompona Scheide, Part IV

Vanilla pompona is resistant to climate change and diseases, and therefore is preferred for hybridization with V. planifolia. Its chemical characterization was carried out in a series of studies, described in this last of four parts.
