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.

A Mathematical Model for Odors Applied to Binary Odor Mixtures

This expanded mathematical model is a modification of Berglund’s model (1973).1 The modification explains the elimination of one odor by another, the synergy of odors of low intensity and the existence of odorless substances, which have deodorant properties.

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.

Modern Analysis Methodologies: Use and Abuse

The considerable “user-friendly” nature of the analytical tools may gradually dull the awareness and critical capacities of analysts, sometimes leading them to produce erroneous or unrealistic results. With the help of examples, this article discusses the wide possibilities of certain techniques, and also their limits.

Fragrance intensity measurement by magnitude estimation

Psychologist's Corner. During the past 25 years a new form of sensory evaluation--magnitude estimation--has become very popular among research scientists in a number of different fields. The premise and forte of magnitude estimation is that people are able to assess sensory intensity by numerical means. Furthermore, the magnitude estimation method allows the participant an opportunity to use a wide range of numbers, with the property that ratios or proportions among the numerical assignments reflect ratios of sensory intensities.

Spectroscopic characterisation of a rare monoterpene from Blumea Mollis

Beginning with earlier studies on the essential oil separated from different species of Blumea, this material has been the subject of many chemical and biological investigations. Chemical investigations of the oils of different Blumea species have afforded different terpenoids. Thus the oil of Blumea eriantha has a major constituent, d-carvotanacetone; oil of Blumea lacera contains the cineol, d-fenchone and citral; oil of Blumea malcolmii yielded d-carvotanacetone and 1-tetrahydrocarvone; and the oil of Blumea membranceae contains 1,4-(8)-p-methadiene; δ-cadinene; 2,3-dimethoxy-p-cymene; 1,2-dimethyl-3-isopropenyl cyclopent-1-en-4-one; 5-hydroxy-p-cymene-2-oxybornylene; 2-methyl-5-isopropyl cyclopent-1-one carbonylic acid methyl ester; and citronellyl acetate. But this monoterpene has not been reported yet.

Odor Memory

Some people claim they can upon command recall specific odors, others think not and argue that such memories consist only of sensory attributes from other modalities. Unfortunately, there seems to be no simple experimental test of such recall for the simple and basic reason that one can not observe another person’s sensory experiences.
