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.

Inside Fragrance Creation: Sustainable Scents

Two top perfumers provide a guided tour of naturals producer Laboratoire Monique Rémy. “Our business is very simple: take [a botanical] at the right moment, and put it in a form which is available to the perfumer the rest of the year,” says Bernard Toulemonde, general manager of IFF subsidiary and naturals expert Laboratoire Monique Rémy (LMR). “Now you know everything,” he jokes.

Aroma Chemicals from Alkyl Halides

The substitution of akyl halides hy zinc salts thus constitutes a very useful synthetic reaction for the preparation of alcohols, ethers, esters, thioethers and thiolesters both under solvolytic and nonsolvolytic conditions. Using this versatile reaction, a large number of allyl, benzyl and tertiary alkyl derivatives, which are widely used in the perfumery and flavour industry, can be obtained. Among these, mention must be made of a-terpinyl, l-menthanyl, myrcenyl, dihydromyrcenyl, benzyl, styrallyl 3,3-dimethyhdlyl and carvyl esters, ethers and alcohols. The inexpensive reagents, convenient reaction conditions and suitability for large-scale operation are attractive features of the method.

Oakmoss and Treemoss in China

Oakmoss products including concretes, absolutes and resinoids have long been used extensively in perfumery. They form important parts of the notes in fougére, chypre or "moss" perfumes, and they are general ingredients in colognes, crêpe de Chines, forest notes, new mown hay, pine fragrances, lavender bouquets, Oriental, fancy or modern bases, etc. Oak moss products can lend body and naturalness, rich pleasant undertones and high fixative value in numerous types of floral fragrances as well.

An aroma chemical profile: Linalool

The small amount of natural Iinalool available is produced from Bois de Rose oils of Brazil and Paraguay and Ho-leaf oil from Taiwan and China. The volume of supply of natural product, however, has been dwarfed by the supply of synthetic product. The demand for linalool cannot be met by the production of natural oils.

Continuous Process for Oakmoss Extraction

Oakmoss (Evernia prunastri L. Ach.), along with other tree mosses, is among the most voluminous botanicals which are solvent extracted for use in perfumes. These extracts are manufactured with heavy labor costs. Large quantities of solvent have to be circulated and evaporated. This requires high energy costs. Therefore, there is a place for a quicker continuous automated process.

An Aroma Chemical Profile: Nonadienols

The nonadienols are truly representative of the term, “specialty aroma chemical,” because their singular and collective volume is small by any standard.
