Is Cineole Detrimental to TeaTree Oil?

This paper evaluates the claims about cineole in tea tree oil and reviews the results of recent skin irritancy and bioactivity investigations which show that cineole is neither an irritant nor an antagonist.

Vanilla flavor is dominated by phenols and their transformation products mostly derived from enzymatic hydrolysis of the phenyl-β-D-glucosides. Cocoa bean flavor is dominated by Strecker aldehydes and pyrazines and other products generated during the roasting process of the beans.

Simple Methods of Odor Quality Evaluation of Essential Oils and Other Fragrant Substances

This paper describes our practical experiences in evaluation of odour quality against standards accepted by perfumers for specified fragrances.

Effects of Structural Modifications on the Odour of Jasmone Analogues

The odour of 2-alkylcyclopentanones can be radically affected by substituents on the first or second carbon atoms of the side chain, substituents further along the chain having a much lesser effect on the odour character. It is postulated that these effects could be rationalised in terms of obstruction of the carbonyl group by a substituent on the first carbon of the side chain or disruption of the side chain conformation by one on the second position

The Influence of Methyl Group Substitution on the Odour of Aliphatic Nitriles

The interesting odour properties of methyl substituted nitriles, coupled with the typical stability/safety properties of nitriles suggest that they will become valuable perfumery materials.

Odor Experience as an Affective State: Effects of Odor Pleasantness on Cognition

A summary of research conducted for the Fragrance Research Fund. This research is designed to investigate the effects of pleasant and unpleasant odors on a variety of cognitive-behavioral responses.

Report on the International Conference on the Psychology of Perfumery

The Second International Conference on the Psychology of Perfumery was held on July 22-26, 1991 at the University of Warwick, Coventry, England. Its ambitious purpose was succinctly defined by George Dodd as advancing our understanding of the interactions between the three Ms: molecules (the olfactory stimuli), membranes (the receptors) and moods (the effects of odors on the organism). The conference provided a few reports of substantive progress towards this goal.

Olfaction Sensitivity in Sleep: The Effects of Fragrances on the Quality of Sleep

A Summary of Research Conducted for the Fragrance Research Fund. Until the series of studies (described below) were conducted only anecdotal accounts but not scientific reports were available concerning olfaction in sleep. We proposed that knowing more about tbe sense of smell in sleep maybe beneficial in terms of safety and in terms of health.

Odor Analysis of (E)- and (Z)-3,7-Dimethyl-4-octen-l-ols and Their Derivatives

This article describes a study of a group of (E)-compounds and a separate group of (Z)-compounds obtained from (E)- and (Z)-isomers of 3,7-dimethyl-4-octen-l-ol.

Evaluation of the Genuineness of Cold-pressed Bergamot Oil

Traditional analyses, high resolution gas chromatographic and chiral analyses.

Study of Fragrance Materials on Controlling Head-Odor Formation

Although there are various reports on bad breath, axillary odor and foot odor1,2, research into head odor is sparse. Therefore, we have performed the following studies aiming to develop fragrant hair cosmetics that control head odor by inhibiting the formation of head-odor-causing materials

On-Line HPLC-HRGC in the Analytical Chemistry of Citrus Essential Oils

In this paper we describe some applications of on-line HPLC-HRGC and HPLC-HRGC-MS in the analysis of citrus essential oils.

Odor tenacity of perfumery materials

When perfumers try to compound fragrances, they must pay attention to the nature of the chemicals used in order to create well harmonized fragrances. It will he easier to create fragrances if the constituents of the essential oils going into them, and their chemical and physical natures, are known. In order to create well balanced perfumes one must know not only the odors of the ingredients but also their odor tenacities. Trained perfumers understand these phenomena from experience, but this kind of experimental data may be helpful to young perfumers.

In vitro antimicrobial studies of the essential oil of Tagetes erects

Tagetes erecta, belonging to the order Compositae, is grown in Indian gardens and is commonly known as “Genda” in Hindi. Its leaves are good for piles, kidney troubles, and muscular pain; its juice is used for earache and opthalmia. The present paper deals with the antimicrobial activity of the essential oil extracted from its leaves by steam distillation in yield of 0.01%.
