Epidermal Bioavailability of Volatile Compounds

Application to fragrance disposition and skin sensitization risk assessment.

Amber Perfumes, Compounds and Specialties

This article will discuss the development and applications of amber perfumes, synthetic amber compounds and specialties.

As one of the most popular and expensive oils of the 19th century, violet oil’s compounds could be isolated into three major ionones. It was found that depending on the synthetic route, mixtures of the ionones in different ratios were formed, each of which had unique fragrance profiles.

Patenting Non-Naturally Occurring Fragrance Compounds

What does the patent literature tell us about innovation in the area of non-naturally occurring fragrance compounds? This short article provides some recent examples of U.S. patents that have claimed “new, useful and non-obvious” non-naturally occurring fragrance compounds or compositions.

First Look: Robertet’s New Fragrance Compounding Facility

Increased automation boosts productivity and output.

Civet and Civet Compounds

Animal Notes in Perfumery. Only a few perfume materials of animal origin are used in perfumery. Among them are musk, ambergris, civet and castoreum. Civet is the subject of this article

Sandalwood and Sandalwood Compounds

Woody Notes in Perfumery

Ozonolysis used for synthesis of odor compounds

This paper concerns, in particular, new or modified methods for the synthesis of odor compounds, drugs, and pesticides.

New Synthetic Odoriferous Compounds

New compounds possessing interesting odoriferous properties can be prepared by employing comparatively simple procedures and may be applied in perfume compositions. 4-Phenyl-1,3-dioxan is the common starting compound used in the synthesis of all eighteen new synthetic odoriferous compounds.

The biosynthesis of terpene compounds

From Wallach's isoprene rule to Ruzieka's biogenetic isoprene rule, the monoterpenes and sesquiterpenes have played a significant role in the development of basic concepts concerning the origin of all terpenoid compounds. Yet, while our understanding of the biosynthesis of higher terpenoids, such as steroids, has flourished progress in the biochemistry of monoterpenes and sesquiterpenes has been relatively slow--due in large part to the chemical nature of the mono- and sesquiterpenes (volatility, instability, and so forth) and to the experimental difficulties associated with the plants that produce these compounds.

Cedarwood and Derivatives in Perfume Compounds, Part II

In the previous article on cedarwood (Perfumer & Flavorist magazine, May/June 2001), we discussed different cedarwood oil types and various cedarwood derivatives. In this article, we will look at the use of cedarwood and its derivatives, as well as specialties in various types of fragrances.

Aroma Compounds of Mango and Papaya from Cameroon

Solid phase microextraction analyses of these important fruits—Mangifera indica L. and Carica papaya L. Mangos (Magnifera indica L., Anacardiaceae) and papayas (Carica papaya L., Caricaceae) are exotic fruits with increasing importance for the crop trade.7,8,10,11,14,38,39

New Compounds with Sandalwood Odor

Sandalwood oil is an essential component of many good perfume compositions, but its scarcity and high price have prompted searches for other compounds with sandalwood odor

Formation of Volatile Compounds from Oakmoss

In the current investigation, the quantitative composition of the volatile components in oakmoss was studied. Also the formation of a few of the interesting monoaryl derivatives will be discussed.

3-Cyclohexylpropanal and 3-Cyclohexylbutanal as Raw Materials for Fragrant Compounds

This study reports an investigation of the hydrogenation of aromatic rings of these alcohols, leading to the respective 3-cyclohexyl-1-alkanols.

Characterization and Sensory Properties of Volatile Nitrogen Compounds from Natural Isolates

Volatile nitrogen compounds occur in many flower scents and essential oils. Although the concentration of these compounds in the natural isolates is often lower than 0.01% (100 ppm); they contribute significantly to the sensory properties of the naturals.

Chemical and Sensory Evaluation of Trace Compounds in Naturals

These compounds reveal characteristic olfactive and organoleptic properties, or are able to modify the overall sensory properties of the end product in a significant way

Oxygen Heterocyclic Compounds of Citrus Essential Oils

In this paper we report the results on the isolation, identification and quantitative analysis of oxygen heterocyclic compounds of bergamot, sweet orange, mandarin, bitter orange, grapefruit and lemon oils.

New compounds with small rings in essential oils

Despite the continuing discovery of new synthetic fragrance raw materials, essential oils still remain the other half of the foundation of perfumery. Consequently, the analysis of essential oils is still very much of interest, as is illustrated by the excellent series of articles by Lawrence in this journal. We now wish to report a number of products containing small (three-, four-, and five-membered) rings, most of which are found for the first time in essential oils. These products were isolated by chemical group separation, liquid and gas chromatography, whereupon the structures were determined by mass, infrared and NMR spectroscopy. All structures were confirmed by synthesis. The essential oils used were obtained from regular commercial sources.
