Cover Story: Leaf Alcohol Preparation

cis-Hex-3-en-1-ol and trans-hex-3-en-1ol are called leaf alcohols, though their aromas resemble freshly cut grass. Perfumers define their aroma more precisely: cis-hex-3-en-1-ol has powerful and intensely green grassy odor.1 Traces of cis-hex-3-en-1-ol are used in refreshing top notes in delicate floral fragrance types such as muguet and lilac; in addition, the alcohol is often used alongside geranium oil, galbanum, oakmoss, lavender and mint oils.

Whiskey lactone is an obvious choice for coconut (especially the toasted kind) and other creamy, mild nut profiles.

Leaf Alcohol

Leaf alcohol and its derivatives are a symbol of the “green revolution in flavors and fragrances that developed in our industry during the 1960’s.” Its commercial introduction changed the nature of flavors and fragrances and resulted in the wide spread use of n-hexenyl based materials, Today, more than 40 structurally related aroma chemicals are being utilized in our industry and all at relatively low formula percentages.

The Composition of Blackcurrant Absolute (Ribes Nigrum)

In our study we employed three different products, an absolute obtained in the laboratory from buds grown in Burgundy of the “Noir Bourgogne” varietv; another laboratory produced absolute from buds collected in Kent, England, from the local variety “Baldwin”; and an industrial produced absolute from buds from various regions of France and elsewhere.

Emission factors of Jasmine Conscious absolute is 87% lower than that of conventional absolute obtained by extraction with hexane.
