Fragrance enhancer

Propiophenone. Propiophenone [93-55-0] (ethyl phenyl ketone) is a colorless Hquid with a flowery odor. It can be prepared by the Friedel-Crafts reaction of benzene and propionyl chloride in the presence of aluminum chloride (346), or by the catalytic reaction of benzoic acid and propionic acid in the presence of water (347). Propiophenone is commercially available (348), and is sold in Japan at 2700 Y/kg (349). It is used in the production of ephedrine, as a fragrance enhancer, and as a polymerization sensitizer. 

Before beginning the analysis of FMs at low concentrations, the laboratory should analyze several laboratory blank samples to assess the degree to which the laboratory is contaminated. With every set of samples analyzed, the laboratory should also analyze a laboratory and field blank sample. Laboratory workers should be advised to be aware of their personal use of fragrance-enhanced consumer products and the potential for laboratory contamination. 

Fragrance enhancers, as their name indicates, are used either to eliminate undesirable odors or to produce desirable ones. Trash bags and kitty fitter liners, for example, may contain additives that absorb undesirable odors generated by their contents. Blow-molded bottles may also contain additives that prevent the product from picking up undesired odors from the surroundings, or that provide for generation of desired odors. Since odors and flavors are highly associated, these same additives can affect taste as well as smell.

Benzophenone is used as a flavour ingredient, a fragrance enhancer, a perfume fixative and an additive for plastics, coatings and adhesive formulations it is also used in the manufacture of insecticides, agricultural chemicals, hypnotic drugs, antihistamines and other pharmaceuticals [16].

Other relatively simple macrolides synthesized by Fiirstner et al. are recifeiolide (96) - a musk fragrance enhancer isolated from Cephalosporium recifei (Equation 1, Scheme 5.22) [47] exaltolide (99) [48] - a musk odorant perfume isolated from Archangelica officinalis, which was the first macrolactone to be prepared by RCM (Equation 2, Scheme 5.22) and muscopyridine (102) (Equation 3, Scheme 5.22) [49], which is present in the secretion of the ventral glands of male musk deer. 

People say they have an enhanced self-image and greater confidence when they think others like their fragrance. 

In flavor formulations, vanillin is used widely either as a sweetener or as a flavor enhancer, not only in imitation vanilla flavor, but also in butter, chocolate, and aU. types of fmit flavors, root beer, cream soda, etc. It is widely acceptable at different concentrations 50—1000 ppm is quite normal in these types of finished products. Concentrations up to 20,000 ppm, ie, one part in fifty parts of finished goods, are also used for direct consumption such as toppings and icings. Ice cream and chocolate are among the largest outlets for vanillin in the food and confectionery industries, and their consumption is many times greater than that of the perfume and fragrance industry.

The molecules produced by living organisms, natural products, are employed in our lives as flavors, fragrances, pharmaceuticals, nontraditional medicines, dyes, and pesticides, among other uses. The products of chemistry are employed in our food as preservatives, artificial sweeteners, thickeners, dyes, taste enhancers, flavors, and textnring agents. Chemistry creates such key materials as plastics, ceramics, fabrics, alloys, semiconductors, liquid crystals, optical media, and biomaterials. Chemistry also does many kinds of analysis and these include measurements of air quahty, water quality, food safety, and the search for substances that compromise the enviromnent or workplace safety. 

The biosynthesis of geosmin is of interest because an enhanced understanding of the pathways and enzymes involved may support the development of effective off-flavor control strategies. Increased biochemical information could also enhance the use of biochemical systems to produce large amounts of geosmin for the flavor and fragrance industries, which may be interested in this compound to provide a desirable earthy note to certain products (88). Currently, difficulties associated with the synthesis of the three chiral carbons renders the chemical synthesis of geosmin extremely difficult (88). 

It is used in fragrances to enhance fruity notes and in strawberry flavors.
