... Le parfum était autrefois utilisé par les artisans de cuir pour neutraliser l'odeur du cuir pour la noblesse [1][2][3][4][5]. Tous les ingrédients utilisées à l'époque étaient des substances issues de plantes [3,[5][6][7]. A partir du XIXème siècle, avec l'avènement de l'industrie chimique, on assiste à l'introduction des substances synthétiques comme ingrédients dans la parfumerie. ...

Le secteur du parfum est très dynamique. Le marché mondial de saveurs et parfums a été évalué à 26,0 milliards de dollars en 2015. Cependant, cette filière est de plus en plus envahie par les substances de synthèse dont l’usage est source de nombreuses maladies cutanées, respiratoires et parfois de cancers. Cette revue donne un aperçu des possibilités d’alternative aux substances de synthèses utilisées et de leurs impacts sur la valorisation des ressources naturelles en Afrique. Les bases de données (Scopus, PubMed) et les moteurs de recherches (Sciences Direct, Research4life, Google Scholar) ont fait l’objet d’une recherche d’articles sur les huiles essentielles d’espèces africaines utilisées en parfumerie à partir de mots clés. Un total de près 300 articles publiés sur les plantes aromatiques utilisées en parfumerie a été consulté et une cinquantaine a été retenue. L'analyse des données a permis de recenser 47 espèces de plantes africaines représentées dans 16 familles. La plupart des espèces rencontrées proviennent des pays d’Afrique du Nord et du Sud. En Afrique de l’Ouest, très peu d’espèces sont utilisées dans les formulations de parfum. Cinq formulations de parfums à base d’huiles essentielles ont également été recensées. Les parfums ont été préparés avec différents supports tel que la vaseline, l’alcool et l’eau. Les parfums ayant comme support l’eau pourrait être une alternative de forme de parfum pour les personnes sensibles à l’alcool.
... In the fine chemical business, fragrances, also known as fragrance ingredients, are a class of substances with a sweet scent or pleasant odour that find extensive use in food additives, perfumes, cosmetics and detergents. [1][2][3][4][5][6][7][8] In this study, cyclopropanation was used to generate the unique scent and flavouring components. Any chemical reaction that produces cyclopropane rings is referred to as cyclopropanation in organic chemistry. ...

In the present communication, synthesis and characterization of several new cyclopropane derivatives of terpene based natural products or their derivatives are reported. The reaction conditions are optimized to obtain products in good to excellent yields. The products obtained are purified and characterized by IR, 1HNMR, 13CNMR and mass. More importantly, the olfactory properties are studied since these chemicals are likely to find extensive use as food additives, fragrance and flavor ingredients.
... Table 2 summarizes some of the potential applications of EOs in the design of cosmetic formulations. [116,117] EOs and EOCs may affect the normal function of skin cells upon topical application, providing to the formulations anti-acne, anti-aging, skin lightening, and sun protection characteristics [24,[118][119][120][121]. Furthermore, they can introduce antibacterial, antifungal, antiinflammatory and antioxidant properties to the formulations which may induce benefits on the hair scalp, and promote an increase of the hair shaft density or cleaning effect on the hair bulb and strengthening of the whole capillary fiber (bulb/stem system) [94,122]. ...

The current consumer demands together with the international regulations have pushed the cosmetic industry to seek new active ingredients from natural renewable sources for manufacturing more eco-sustainability and safe products, with botanical extract being an almost unlimited source of these new actives. Essential oils (EOs) emerge as very common natural ingredients in cosmetics and toiletries as a result of both their odorous character for the design and manufacturing of fragrances and perfumes, and the many beneficial properties of their individual components (EOCs), e.g., anti-inflammatory, antimicrobial and antioxidant properties, and, nowadays, the cosmetic industry includes EOs or different mixtures of their individual components (EOCs), either as active ingredients or as preservatives, in various product ranges (e.g., moisturizers, lotions and cleanser in skin care cosmetics; conditioners, masks or antidandruff products in hair care products; lipsticks, or fragrances in perfumery). However, the unique chemical profile of each individual essential oil is associated with different benefits, and hence it is difficult to generalize their potential applications in cosmetics and toiletries, which often require the effort of formulators in seeking suitable mixtures of EOs or EOCs for obtaining specific benefits in the final products. This work presents an updated review of the available literature related to the most recent advances in the application of EOs and EOCs in the manufacturing of cosmetic products. Furthermore, some specific aspects related to the safety of EOs and EOCs in cosmetics will be discussed. It is expected that the information contained in this comprehensive review can be exploited by formulators in the design and optimization of cosmetic formulations containing botanical extracts.
... At agronomical level the essential oils from mint species revealed insecticidal properties being considered ecofriendly pesticides, assisting in the crop protection against pests (Kumar et al., 2011). Their exhaled fragrance, highly enjoyed, is employed in perfumes and cosmetic products (Silva-Santos et al., 2007). At medicinal and pharmaceutical levels, extracts and/or essential oils from mint species revealed inhibition of acetylcholinesterase activity (Miyazawa et al., 1998), andvasodilatation (McNeill andJurgens, 2006), among others health benefits (Edris, 2007). ...

In the present work, the effect of the geographical origin on the mass production, and essential oil content and composition of fresh and dry leaves of spearmint (Mentha×villosa Huds.) was evaluated. Field experiments were conducted in three different municipalities (Amargosa, Cruz das Almas and Santo António de Jesus) from Bahia region (Brazil) and two drying methodologies (natural and artificial with controlled conditions) were assessed. Fresh and dried leaves essential oils were extracted by hydro-distillation and their volatiles were determined by gas chromatography with a flame ionization detector (GC/FID) and by gas chromatography with a mass selective detector (GC/MS). The results showed that Cruz das Almas field reported higher biomass production and Santo Antônio de Jesus higher leaves essential oil content. The natural and artificial drying methodologies affected in a similar way the leaves essential oil content in each region, but they affected considerably their composition. Eighteen volatile constituents were identified, mainly sesquiterpenes and monoterpenes, where piperitenone oxide and germacrene D are in higher abundance. By applying a PCA it was possible to distinguish the fresh leaves from each region from the leaves dried by the different drying methodologies, highlighting the increase of minor compounds, mainly sesquiterpenes in the dried leaves from Santo Antônio de Jesus.
Conference Paper
Aromatic-based solvents, including benzene, toluene, xylene (BTX) and their derivatives have been successfully applied for asphaltene removal from downhole and surface facilities. These solvents are considered non-environmentally friendly due to their associated health and safety concerns including high toxicity, low biodegradability and low flash point. Currently, more attention has been given in the oil industry to develop environmentally friendly asphaltene solvents. This paper examines several environmentally friendly solvents derived from natural precursors to dissolve asphaltene, wax and combined asphaltene/paraffin organic deposit. A group of plant-derived and terpene-based asphaltene solvents with flash points ranging from 50.5 to 136 °C was examined in this study. Extracted asphaltene from a crude oil and wax obtained from distillation were used to assess solvency power of these solvents. Solubility of organic deposits containing more 42 wt% asphaltene with associated paraffin was evaluated in these solvents. The performance of these solvents was examined as a function of soaking time and temperature. These environmentally friendly solvents showed comparable solvency power to toluene. The lowest flash point solvent exhibited the highest solvency power for asphaltene while the opposite relation was observed for the wax sample. The lowest flash point (50.5 °C) solvent was able to dissolve 91 wt% of the asphaltene sample after soaking for 2 hours at ambient temperature compared with the highest flash point solvent (136 °C), which dissolved only 7.4 wt% at the same conditions. For wax, the solvent with the second highest flash point (132 °C) was able to dissolve 97 wt% of the wax while the solvent with a flash point of 50.5 °C was able to dissolve 85.5 wt% at ambient temperature and after 2 hours. Some of the examined environmentally friendly solvents showed very high dissolution power to organic deposits composed of asphaltene and paraffin where a solubility of 96 wt% was obtained at 80 °C and after a soaking time of 6 hours. The paper will discuss these results in detail.
