Patent Pick: Clean, Floral 1-(2,4-Dimethyl-cyclohex-3-enyl)-propan-1-ol

Patent Picks are chosen by the editors from publicly available sources. Today's invention, from IFF, is a novel 1-(2,4-dimethyl-cyclohex-3-enyl)-propan-1-ol compound having clean, fresh and floral characteristics.

Dihydrocarvone

The purpose of this paper is to illustrate many interesting chemical aspects, such as methods of preparation and reactions of dihydrocarvones which resulted in important aroma chemicals.

Synthesis and odor characteristics of some 6,6-dimethylbicyclo [3.1.0] hexane derivatives

It can be generally stated that the odor of the compound group under investigation, containing 8-10 carbon atoms in the molecule, is strongly influenced by the 6,6-dimethylbicyclo[3.10]hexane system which decides their common characteristic camphoric-penetrating odor.

Synthesis and Odor Characteristics of New Gem-Dimethylcyclohexane Derivatives

Searching for cyclic analogs of the insect juvenile hormones, we synthesized a series of new compounds containing the cyclogeraniolene system. This system can be considered as a cyclic form of acyclic terpenes, such as dihydrocitronellol, dihydrogeraniol, and menthocitronellol. The isoprenoid chain in these compounds is rolled to form the cyclohexane ring by connection of the carbon atoms C-7 and C-10. As compared with the classical cyclic systems of the cyclogeraniol type, the compounds obtained by us contain the gem-dimethyl groups in the 3-position in relation to a chain with the functional group.

IFRA to Prohibit 2,4-Double Conjugated alpha, beta Unsaturated Aldehydes

The International Fragrance Association (IFRA) is expected to prohibit the use of 2,4-hexadienal (CAS# 80466-34-8) and other 2,4-double conjugated alpha, beta unsaturated aldehydes as part of the 44th Amendment to the IFRA Code of Practice.

Cycloheptadecanone from Dimethyl Octadecanedioate via a One-Step Catalytic Process

Although the reaction was not studied, it does establish that a one-step conversion of the long chain diesters to the cyclic ketone containing one less carbon atom can occur. It opens the possibility to simpler processes for the preparation of macrocyclic ketones.

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.

Aroma360 Revamps Scent Marketing with Interactive Scenting Kiosk

The ISK is said to combine the traditional elements of visual advertising, interactive e-commerce and the science of scent to influence customer purchasing behavior.

Regulatory Happenings on the Horizon

One of the biggest challenges facing perfumers and flavorists today is the constant change in regulations. In fact, in order to keep track of and address the barrage of new regulations, most companies have set up their own regulatory departments. Among the most important regulatory issues in the past couple of years has been REACH (Registration, Evaluation, and Authorization of Chemicals).

Through interactive scent experiences, attendees explored the profound link between fragrances, sense of smell, and sense of well-being.
