Copyright 2015 Agilex Fragrances A Fragrance Glossary 2015 Copyright 2015 Agilex Fragrances A Absolute Concentrated, highly aromatic oily mixtures extracted from plants. The method by which they are extracted affects the odor of the absolute. Accord A blend of materials targeting a specific odor or odor type that can be used as the basis of a fragrance or added to build complexity. Ambergris A biologic substance expelled from the digestive tract of the sperm whale. Upon aging on the open water, exposed to sun and salt, it develops a unique warm, balsamic odor. It is highly prized for this odor and its fixative properties, but is rarely used. Amber Amber, as it is used in perfumery, is not related to the fossilized resin of the same name. A perfumers Amber is an accord, usually based on labdanum, which imparts a warm, sensual, lightly sweet, balsamic odor. Animalic An odor group used to describe the sharp, tangy, sensual, and warm characteristics of the extracts made from certain animals: civet, beaver, musk deer and sperm whale. With the exception of the Sperm Whale, harvesting the materials results in the death of the animal. To ease consumer sensibilities a variety of similar synthetic chemicals have been developed. Aromatic Traditionally used to describe the very large group of plants and herbs used as flavorings in various cuisines. A few examples are: Basil, Anise, Sage, Dill, Lemongrass, Spearmint. B Balsam A resin or sap which forms on various trees and shrubs such as myrrh and evergreens. Balsamic odor classification is warm, rich, and slightly sweet. Base The foundation of a fragrance, the base delivers the undertones that modify and enhance the layers above it, and becomes more evident as the fragrance is worn. Blotter A compressed paper of varying thicknesses used to evaluate or showcase a fragrance. Bouquet In traditional perfumery, this describes the aroma of a complete and properly aged fragrance. It is the combined effect of the individual ingredients after any interactions have completed. It has a similar meaning in the descriptions of wine. C Chypre A classical accord named for the Isle of Cyprus. It is made by blending Oakmoss with Bergamot, a floral (usually Rose or Jasmine), Patchouli and Cedarwood. It is a very versatile accord and can be enhanced by adding green, fruity or citrus notes. This accord is suitable for feminine and masculine fragrances. Citrus Oils Among the most valuable oils used are those obtained from fruits such as orange, lemon, lime, tangerine, mandarin and bergamot. They impart freshness to fragrances. Cloying Term used to describe an extremely strong and overly sweet or heady fragrance. Concrete An extraction method that uses a solvent, usually hexane or benzene, to separate the fragrant components of a botanical material. The solvent is evaporated and the resulting waxy material is the concrete. This can be used as is or is refined into absolute. D Diffusion Diffusion is the rapid evaporation of a fragrance. A fragrance that can quickly fill a space with its scent is said to be diffusive. (i.e. cologne radiating off the skin or a scented candle filling the room with scent) Distillation Distillation is the process in which steam is used to release the volatile components of botanical for use in fragrance. The recovered product is known as an essential oil. Flowers, leaves, stems, wood and seeds are all distilled to produce essential oils. Drydown The drydown is the final portion of the evaporation process of a fragrance. The drydown is also referred to as the bottom. The scent remaining on the skin after many hours or on clothes coming out of the dryer would be considered the drydown. E Enfleurage An ancient process of releasing the volatile components from delicate flowers such as tuberose. The flowers are placed on fat until their scent is absorbed into the fat. The fat is then removed leaving the fragrant portion known as absolute pomade. Essential Oils The volatile product obtained from botanicals via distillation. Evaporation The process of changing from liquid to vapor. Expression The process of obtaining the volatile oils from citrus peels by mechanical pressure applied to the peels is known as expression. Extraction Extraction is the process in which the volatile materials are released from botanicals by solvent. The product obtained is called the concrete. Ethyl alcohol is used to remove the insoluble waxes from the concrete to form the absolute. F Fixatives Fragrance raw materials that are used to slow the evaporation process. Flowery A term used to describe the aroma of a flower, such as jasmine, rose, lily, etc. Fougere A class of fragrances or an accord which contains citrus, lavender, oakmoss and coumarin. Fragrance A blend of raw materials, natural and synthetic, combined to make any odor. Fresh A highly subjective term applied to fragrances that have a light, sparkling top note. This effect is often achieved by using citrus notes, although not exclusively. G Gourmand In fragrance, referring to the odor of food or desserts that are baked. Green A term used to describe a nature inspired aroma that may consist of plants and vegetation and is crisp, earthy, stem like, leafy or fresh. H Hedonic In fragrance, pertaining to the level of liking or acceptance of a scent. I Infusion Dilution of botanicals, like Vanilla bean, in alcohol. L Lift The amount of diffusion a fragrance exhibits in a product. Highly diffusive fragrances have good lift. M Maceration / Fragrance Maceration is the aging of fragrances in alcoholic solutions. Maceration time can vary greatly and affects the body & strength of the finished perfume. Maceration / Extraction In this process of extraction, the flowers are soaked in hot oil to have their cell membranes ruptured and the hot oil then absorbs the essence of the flowers. Middle Notes Middle notes emerge just before the top notes dissipate, usually after 1-2 hours on a blotter. They are the body of the fragrance and help cover base notes that take time to develop their depth and richness. Modern A subjective interpretation used to describe a fragrance composition updated using current trend accords. Mossy Mossy notes are reminiscent of the rich depths of a forest. Musk Originally derived from the gland of the male Musk Deer, it has been replaced by the use of synthetic musks. There are a large variety of synthetic musks whose odors range from dark and animalic to fresh and laundry-like. They have the unique ability to balance a fragrance composition and add a subtle touch of sensuality and warmth. Musks also act as a fixative, giving the fragrance longer lasting power. N Notes How an ingredient smells in a fragrance but is sometimes loosely used for an entire accord. O Olfactive Pertaining to the sense of smell, or how a fragrance smells. Oriental A unique blend of citrus, warm amber & vanilla notes. Often this accord is enhanced with precious woods, exotic floral or spicy undertones. Oriental notes can make a fragrance full-bodied and add warmth & sensuality. P Perfume Types Grouping by olfactive family is a starting point to describe fragrances but it cannot by itself denote all the characteristics of that fragrance. The traditional classification categories are: Floral- oriental-amber-woody-leather-chypre-fougere. More categories have come into existence like green, ozonic or gourmand. Pomade Pomades are prepared perfume materials that are obtained through the enfleurage process. The fat saturated with oil from the flowers is known as the pomade. Powdery Powdery applies to a natural or synthetic note that gives the feeling of dryness associated with talcum pow- der or chalk. Many people associate powdery with the “smell of a baby” or baby powder. Powdery notes can take on sweeter nuances or drier ones depending on what the perfumer is trying to accomplish. R Round Out In fragrance, to add body, fullness or depth as a means to complete or enhance a fragrance composition. S Spicy Fragrance classification relating to strong botanical extracts such as cinnamon, clove ginger or pepper. Stability Term used to refer to a fragrances ability to be nonreactive with itself or its base. Fragrances are made stable to avoid issues such as discoloration. Stability tests try to replicate potential long term storage issues before a product goes to market. Strength The relative power of a fragrance blend. Substantivity The overall strength and lasting power over time. Sweet A fragrance category classified by the level of vanillic, sugary notes. Sweet notes are typically bottom notes that last the longest. T Thin A fragrance lacking in complexity or body. A thin fragrance is very linear or single noted. Top Note The very first perceived part of a fragrance. It usually consists of citrus notes and/or light fruity or green notes. The top notes are the first to dissipate. U,V,W Undertone The underlying feeling or quality of a fragrance. Volatile The measure of how fast a fragrance vaporizes, evaporates or diffuses. Woody A fragrance term associated with fresh cut wood. Woody notes can be subdivided ever further. Warm, opulent woody notes such as sandalwood or patchouli, or dry aromatic notes such as cedarwood or vetiver can all be used to enhance a fragrance composition..

  • Effect of Different Extraction Methods on Yield and Quality of Essential Oil from Four Rosa Species
    Floriculture and Ornamental Biotechnology ©2007 Global Science Books Effect of Different Extraction Methods on Yield and Quality of Essential Oil from Four Rosa Species Adnan Younis1* • Muhammad Aslam Khan1 • Asif Ali Khan2 • Atif Riaz1 • M. Aslam Pervez1 1 Institute of Horticultural Sciences, University of Agriculture, Faisalabad, Pakistan 2 Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad, Pakistan Corresponding author : * [email protected] ABSTRACT In the present study rose oil was extracted from the petals of four Rosa species i.e. R. damascena, R. centifolia, R. borboniana and Rosa 'Gruss an Teplitz' through solvent extraction through hexane, solvent extraction through ether and steam distillation. R. damascena yielded (0.145%) of absolute oil, R. centifolia yielded 0.11% whereas R. 'Gruss an Teplitz' yielded the least (0.035%) absolute oil. Solvent extraction through hexane yielded more absolute oil (0.11%) than steam distillation (0.075%) and solvent extraction (0.07%) through ether on petal weight basis. Gas-chromatography of the rose oil was carried out for the qualitative and quantitative analysis of the oil constituents. Major compounds identified were citronellol, methyl eugenol, geraniol, geranyl acetate, phenyl ethyl alcohol, linalool, benzaldehyde, benzyl alcohol, rhodinyl acetate, citronellyl acetate, benzyl acetate and phenyl ethyl formate. Both techniques (solvent extraction and steam distillation) yielded oil with differences in the percentage composition of each component, but solvent extraction through hexane proved better (i.e. higher yield and more components) than steam distillation for extraction of essential oil from roses. _____________________________________________________________________________________________________________ Keywords: citronellol, essential oil composition, Rosa centifolia, solvent extraction, steam distillation INTRODUCTION essential oil, which is slowly liberated from the plant material (Durst and Gokel 1987; Wilson 1995).

Although Nicotiana species have been extensively investigated, relatively less research has focused on flowers, especially research related to obtaining aromatic products for cosmetic and perfumery use. On the other hand, there is evidence that Nicotiana flowers accumulate various secondary metabolites with a distinct aroma and biological activities, and the flowers represent a biomass available in sufficient quantities. Therefore, this study aimed to determinate the chemical composition (by GC-MS) and the olfactory profiles of a specific type of natural aromatic product (concrete), obtained from the flowers of four Nicotiana species, in a direct comparison between them.

  • Essential Oils (Volatile Oils)
    Essential Oils (Volatile Oils) Prof. Dr. Ali H. Meriçli Essential oils (essences, volatile oils) are products, generally of rather complex composition, comprising the volatile principles contained in plants, and more or less modified during the preparation process. To extract these volatile principles, there are various procedures. Of these, only two may be used to prepare official oils : steam distillation of oil-containing plants or of selected plant parts (mostly with Clevenger apparatus) and expression. The second way is recommended for obtaining the Citrus fruit oils. The definition by procedure is restricitive : it excludes the products obtained by solvent extraction, as well as those obtained by any other process (pressurized gas, enfleurage, and others). Therefore it is useful to first define the terms most commonly used in this field. - concrete : extract of characteristic odor, obtained from a fresh starting material of vegetable origin, by extraction with a non- aqueous solvent - resinoid : extract of characteristic odor, obtained from a dried starting material of natural origin, by extraction with a non-aqueous solvent. Here starting material of natural origin means “of vegetal, animal, or microbiological origin, including products derived from these starting materials by enzimatic routes. - pomade : perfumed fat obtained from flowers either by “cold enflorage” or by “hot enflorage”. Enfleurage is a process that uses odorless fats that are solid at room temperature to capture the fragrant compounds exuded by plants. - absolute : product of characteristic odor, obtained from a concrete, a pomade, or a resinoid, by ethanol extraction at room temparature. The resulting ethanol solution is generally cooled and filtered in order to eliminate waxes; the ethanol is than removed by distillation.

  • 23. Organic Emissions from Petroleum-Contaminated Soil Fixed in Concrete
    Journal of Soil Contamination, 5(1):35–52 (1996) Organic Emissions from Petroleum- Contaminated Soil Fixed in Concrete Hossam S. Ezeldin, M.S.1 and David A. Vaccari, Ph.D., P.E. 2 1Langan Engineering and Environmental Services, Inc., Elmwood Park, NJ 07407; 2Stevens Institute of Technology, Center for Environmental Engineering, Hoboken, NJ 07030 ABSTRACT: This study investigated a solidification treatment process for soils that are contaminated with hydrocarbons at levels of 0.5 and 3.0% by weight of benzene. The contami- nated soils were bound in a concrete matrix and the migration of organics from the concrete to air was evaluated. If the hydrocarbon emissions are sufficiently attenuated, the concrete contain- ing such contaminated soil can be used for exterior construction applications. The experimental specimens consisted of concrete mixtures in which 40% of the sand was replaced with the contaminated soil. The mixtures’ ratio of cement, aggregate, sand, and water is 1:1.5:1.5:0.5 by weight. The study included specimens with and without class C fly ash replacing 10% of the cement. In addition, two unfixed control specimens were prepared for each contamination level. The concrete-soil mixtures were placed in sealed jars and air was passed through the head space of the jars and then through carbon adsorption tubes for measurement of contaminant flux from the surface of the specimens. Measurements were made during and after concrete curing. The results were fitted to a Fickian diffusion model to estimate effective diffusivity in the concrete-soil specimens. The test results showed that the effective diffusivity of the contaminant within the concrete was reduced by three to five orders of magnitude over the molecular diffusivities in unfixed contaminated soil used as control.

    ORIGINAL ARTICLE Rec. Nat. Prod. 10:5 (2016) 555-565 Variation in Scent Compounds of Oil-Bearing Rose (Rosa damascena Mill.) Produced by Headspace Solid Phase Microextraction, Hydrodistillation and Solvent Extraction Sabri Erbaş* and Hasan Baydar Suleyman Demirel University, Faculty of Agriculture, Department of Field Crops, 32260, Isparta-Türkiye (Received December 03, 2014; Revised August 17, 2015; Accepted December14, 2015) Abstract: In this research, rose oil and rose water were hydro-distilled from the fresh oil-bearing rose flowers (Rosa damascena Mill.) using Clevenger-type apparatus. Rose concretes were extracted from the fresh rose flowers by using non-polar solvents, e.g. diethyl ether, petroleum ether, cyclo-hexane, chloroform and n-hexane, and subsequently by evaporation of the solvents under vacuum. Absolutes were produced from the concretes with ethyl alcohol extraction at -20°C, leaving behind the wax and other paraffinic substances. Scent compounds of all these products detected by gas chromatography (GC-FID/GC-MS) were compared with the natural scent compounds of fresh rose flower detected by using headspace solid phase microextraction (HS-SPME) with carboxen/polydimethylsiloxane (CAR/PDMS) fiber. A total of 46 compounds analysis were identified by HS- SPME-GC-MS in the fresh flower, and a total of 15 compounds were identified by GC-MS in the hydrodistilled rose oil. While main compounds in rose oil were geraniol (35.4%), citronellol (31.6%), and nerol (15.3%), major compound in fresh rose flower, rose water and residue water was phenylethyl alcohol (43.2, 35.6 and 98.2%, respectively). While the highest concrete yield (0.7%) was obtained from diethyl ether extraction, the highest absolute yield (70.9%) was obtained from the n-hexane concrete.
