Dryobalanops aromatica merupakan tumbuhan berkayu penghasil minyak dan kristal yang memiliki nilai ekonomis tinggi. Saat ini minyak dan kristal menjadi komoditas eksport untuk keperluan kosmetik dan ...obat-obatan. Di masyarakat, minyak ini hanya dimanfaatkan secara terbatas pada pengobatan sederhana pada berbagai penyakit ringan. Pemanfaatan di dalam negeri masih sangat terbatas, sehingga diperlukan penelitian yang mengarah pada peningkatan nilai tambah dari minyak ini. Pemanfaatan sebagai bahan pewangi/ parfum, diharapkan dapat meningkatkan nilai tambahnya. Hasil penelitian menunjukkan bahwa formula parfum minyak Dryobalanops yang disukai berdasarkan uji organoleptik adalah minyak Dryobalanops (25%), dengan etanol (75%) dan campuran bahan aditif berupa odorant green tea, PG dan minyak nilam (0,8%). Formula ini memiliki karakteristik tingkat keharuman yang lembut (harum), dengan ketajaman aroma pada tingkat agak tajam. Dari analisis kimia minyak Dryobalanops aromatica diketahui bahwa minyak memiliki senyawa penanda borneol dan senyawa lainnya yaitu Caryophyllene; 3-Cyclohexene-1-methanol,.alpha.,.alpha.,4-trimethyl-, (S)-(CAS) p-Menth-1-en-8-ol,(S)-(-)-; 1,4,7,-Cycloundecatriene, 1,5,9,9-tetramethyl-, Z,Z,Z- dan 3-Cyclohexen-1-ol, 4-methyl-1-(1-methylethyl)- (CAS) 4-Terpineol.
Aromatic volatile compound from melon (Cucumis melo L.) cv. Gama Melon Parfum (GMP) has not been identified. The purpose of this study is to identify aromatic volatile profile and measure the key ...pleasant aroma of GMP melon. Sample was taken from garden then store at temperature -20°C. The volatile compounds was extracted by cold maseration method, then concentrated using vigregous column. Volatile extract was analysed using GC-MSOlfactometry. The result showed that some identified aromatic volatile compounds consisted of 3 alcohols, 3 esters, 1 ketone and 1 hydrocarbon. Interestingly, the key aroma characteristics of GMP melon was influenced by 3-penten-2-ol, hexyl acetate and 3-hydroxy 2-butanone.
De nos jours, l’encapsulation est une technique très répandue dans le domaine de la parfumerie. En effet, elle permet une libération contrôlée du parfum et une protection des molécules de parfumerie ...qui peuvent s’oxyder avec le temps. L’objectif de cette thèse a été de mettre au point un nouveau concept de capsules fondé sur la formulation d’émulsions doubles huile-dans-eau-dans-huile et de polymériser la phase aqueuse intermédiaire. Les phases huiles, intérieure et extérieure, sont respectivement constituées du parfum et d’un solvant de parfumerie. La phase aqueuse est, elle, composée de monomères hydrophiles dont la polymérisation radicalaire permet l’obtention d’une matrice polymère plus ou moins diffusive vis-à-vis du parfum. L’intérêt de ce nouveau principe d’encapsulation est de séparer la polymérisation et les molécules de parfumerie qui peuvent être réactives en polymérisation radicalaire en les localisant dans des compartiments distincts et ainsi éviter toute interaction. Cette stratégie qui combine la Science des Emulsions, des Polymères et des Parfums et la Formulation a permis l’élaboration de capsules robustes possédant des propriétés de libération progressive par diffusion et de libération provoquée par application d'une contrainte mécanique sans altérer l'intégrité des capsules. Elles se comportent alors comme des micro-éponges capables de se déformer et de reprendre leur forme initiale. Dans ce schéma général, les propriétés peuvent être modulées plus finement par le choix et les concentrations des réactifs lors de la synthèse.
Nowadays, encapsulation is a widespread technology in fragrance applications. Indeed, it allows control of the fragrance release as well as protection of the fragrance molecules with respect to oxidation. The objective of this PhD is the development of a new concept of encapsulation based on the formulation of double oil-in-water-in-oil emulsion and the polymerization of the intermediate aqueous phase. The two, internal and external, oil phases, , are respectively the fragrance and perfume solvent while the aqueous phase is composed of hydrophilic monomers leading to a more or less fragrance-diffusive polymer matrix after their radical polymerization. The main advantage of this encapsulation principle is to locate the polymerization and the possibly reactive fragrance’s molecules in separate compartments. This strategy which combines the Sciences of Emulsion, Polymers and Fragrance but also the Formulation allows obtaining robust capsules exhibiting both diffusive properties and a triggered release under a mechanical stress. These capsules behaves as micrometric sponges that can deform and restore their initial state.. In this general scheme, the capsules' properties can be tuned by an appropriate choice of the polymerization reactants and their concentrations.
This book advises the reader from an analytical chemistry perspective on the choice of suitable analytical methods for production monitoring and quality control of cosmetic products. This book will ...enable people working in the cosmetic industry or in research laboratories to become familiar with the main legislative and analytical literature on this subject and learn about and choose suitable analytical procedures for production monitoring and control of cosmetic products, according to their composition. The first section of the book covers various definitions and concepts relating to cosmetic products, current legislation in different countries and specific legislation on ingredients. The central body of the book addresses analytical methods for monitoring and quality control of cosmetic products with the fundamental objective being to enable reader's access to scientific reviews carried out by experts in analytical chemistry. The final section contains a small review of the alternative methods to using animals for cosmetic product evaluation. This book will benefit scientists, technologists, students, practitioners, consultants, etc.
The series "QUELLEN UND FORSCHUNGEN ZUR LITERATUR- UND KULTURGESCHICHTE" (Sources and Research in the History of Literature and Culture), with a rich tradition stretching back to 1874, is an ...established feature among the renowned publications for German Literary Studies. Edited by Mark-Georg Dehrmann and Christiane Witthöft, the series presents examples of high-quality scholarship examining literary texts in conjunction with historical cultural phenomena, particularly with the other arts. There is an explicit demand for literary studies with a transdisciplinary approach. German literature from the Middle Ages to the present day forms the main focus of the series. As the historical cultural thrust of the series includes aspects of intercultural experience and national perceptions of the other, Quellen und Forschungen is also open to occasional comparative studies. The publications of the series include monographs, doctoral and professorial theses. Works presented for acceptance in the series are required to display scholarly relevance and excellence in method and presentation.
