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.

Green Seal GS-37 Standard Voted Down

The Green Seal GS-37 Draft Final Revised Standard, which the FMA opposed, was voted down by a margin of 57 to 43.

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.

FMA Study: Fragrance Residues from Candles

The FMAhas announced the publication of its study "Skin contact transfer of three fragrance residues from candles to human hands."

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.

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.

Study Connects Olfaction and Neurodegenerative Disease

A study on the relationship between olfactory deterioration and neurodegenerative disease will be addressed by the collaboration between Monell Center and the Brain Health Registry.

Olfactory Perception in Infants

The research reported here was undertaken to develop new methodology for evaluating olfactory perception in infants. Prior research has shown that, while newborn infants are capable of making fine olfactory discrimination, adult-like odor preferences and aversions are not apparent until five years of age.
