A recent study from The Monell Center found the connection between the olfactory marker protein (OMP) and the detection of different scents after a 30-year-old mystery.
The inventors on this fragrance patent traded the two-step (or more) fragrance synthesis dance for a more economic, one-step solution.
Phew—smell that? Odors are out there, lingering until heat and humidity unleash their dirty-socks-in-the-gym-bag potential. That's where pro-scent solutions like this Henkel compound come in, locked and loaded.
Lights, cameras, vanillin! A new patent application from BASF describes a novel stilbene whose vanilla-like odor intensifies under artificial or natural light.
Due to its stability, this material finds use in a large number of products in the fragrance industry.
The author discusses the chemical components of clary sage oil.
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.
If you have engaged in odor testing sessions, you know how exhausted you feel after half an hour of concentrated effort. Working near the threshold level is very difficult indeed. There can be agonies of indecision. I have always told my observers that it is their first snap impression that counts and is usually right. The chemical senses in our bodies are wonderfully designed and will come out with “I can smell it” or “l can’t smell it” instantaneously.
Our research effort continues with other fluorocarbon compounds, which may offer better end use performance and economic characteristics than those provided by FC-22 and FC142b. The goal is to find propellants that present the greatest consumer advantages should circumstances dictate the replacement of the propellants presently used.
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.
