Searching the patent literature for flavor and fragrance materials

When searching the perfumery or flavor use of a chemical, novel or not, two places in each classification system should be searched: all organoleptic use class(es), and the chemical per se class. At a minimum, the search should cover the U.S. Classification system, the International Patent Classification, the standard chemical literature (e.g. Beilstein and Chemical Abstracts), and the standard literature of our industry: Bedoukian’s Perfumery and Flavoring Synthetics, Arctander’s Perfume and Flavor Chemicals (Aroma Chemicals) Vol. I and II, and the Fritzsche library bulletin.

Material Review: Clary Sage Oils

Variation in composition and enantiomeric analyses of commercial vs. new Kashmir clary sage oils. Commercial clary sage oils were analyzed along with a newly available Kashmir oil (Himalayan Foothills Oils, Srinagar, India). All of the oils were high in linalool (14.7–25.1%) and linalyl acetate (55.0–72.4%).

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.

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.

The Safety of Fragrance Materials

When one considers the long history of the use of fragrances, their broad distribution, and the extent of exposure to them, one is impressed with the very few examples of injury to humans that can be attributed to these materials, The only problems reported have been occasional rashes on the skin, and even more specificalIy, light-induced rashes. And yet there is a persistent myth in the cosmetic industry that any problem encountered in the safety testing of a new cosmetic must be attributable to the fragrance component. Only systematic screening of all of the materials used in fragrances by an independent scientic body, and systematic and voluntary conscientious response by the industry to eliminate ingredients shown to cause harm can dispel this myth.

F&F Literature Review: Value-added F&F Materials

Value-add occurs in flavor and fragrance development, too. In some cases, it’s a material that supports a natural or clean label claim. In others, it’s a process that yields extracts of a higher purity or activity; or materials with health, wellness or benefits beyond their basic flavor or fragrance function.

Perfume Raw Material Safety—The Role of IFRA

The recommendations of IFRA are a description of good manufacturing practices of the fragrance industry. Since the recommendations have been published, they are open to scientific criticism. The fact that they remain unchallenged gives additional weight to their status as a generally accepted expert opinion.

Separation of Fragrance Materials from Perfumed Consumer Products

In isolating the fragrance materials, which are usually present only at low levels, the analytical chemist is confronted with a formidable separation challenge, particularly when the sample also contains emulsifiers, surfactants, clarifiers, thickeners, solubilizers, pigments, antioxidant, UV-absorbers, preservatives, solvents, and other materials.

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
