Download or read book Hydrosols written by Suzanne Catty and published by Simon and Schuster. This book was released on 2001-03-01 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: • The first book devoted exclusively to aromatic hydrosols--gentle, water-based plant extracts that expand the healing, cosmetic, and culinary applications of aromatherapy. • The newest development in the field of aromatherapy. • The homeopathic form of aromatic treatment that is the perfect complement to other forms of vibrational medicine. • A comprehensive reference with more than 100 recipes and formulas for using hydrosols as well as sources of supply. • With an introduction by Kurt Schnaubelt, author of Advanced Aromatherapy and Medical Aromatherapy. Hydrosols is one of the most anticipated books in the world of holistic health because it introduces a revolutionary new use of essential oils in aromatic treatment. Hydrosols, or hydrolates, are the pure, water-based solutions created when essential oils are steam distilled. Through this process, a potent, yet subtle form of medicine is created, one that is able to be ingested as well as applied directly to the skin, unlike most pure essential oils. In fact, hydrosols are considered the homeopathic version of aromatherapy, and as such are ideal for use with children, animals, and those with fragile immune systems. Suzanne Catty details the specifics of 67 hydrosols, provides formulas to treat more than 50 health concerns, and offers 40 delicious recipes in which hydrosols can be used. Her section on pets will help owners deal with urinary tract and digestive problems as well as grooming and odor issues. She also shows how hydrosols can be used with other forms of vibrational medicine and with feng shui, geomancy, and dowsing.

Download or read book Supercritical Fluids written by E. Kiran and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercritical fluids are neither gas nor liquid, but can be compressed gradually from low to high density and they are therefore interesting and important as tunable solvents and reaction media in the chemical process industry. By adjusting the density the properties of these fluids can be customised and manipulated for a given process - physical or chemical transformation. Separation and processing using supercritical solvents such as CO2 are currently on-line commercially in the food, essential oils and polymer industries. Many agencies and industries are considering the use of supercritical water for waste remediation. Supercritical fluid chromatography represents another, major analytical application. Significant advances have recently been made in materials processing, ranging from particle formation to the creation of porous materials. The chapters in this book provide tutorial accounts of topical areas centred around: (1) phase equilibria, thermodynamics and equations of state; (2) critical behaviour, crossover effects; (3) transport and interfacial properties; (4) molecular modelling, computer simulation; (5) reactions, spectroscopy; (6) phase separation kinetics; (7) extractions; (8) applications to polymers, pharmaceuticals, natural materials and chromatography; (9) process scale-up.

Download or read book Extraction of Natural Products Using Near Critical Solvents written by M.B. King and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present the current state of the art of extracting natural products with near-critical solvents and to view the possibilities of further extensions of the technique. Relevant background theory is given but does not dominate the book. Carbon dioxide is the near-critical solvent used in most recent applications and inevitably receives prominence. In addition to general descriptions and reviews, the book contains three chapters by indus trial practitioners who describe in detail the operation of their processes and discuss the market for their products. Sections on the design of the pressure vessels and pumps required in these processes and on the acquisition of the data required for design are included. The costing of the processes is also discussed. There is good scope for combining a near-critical extraction step with other process steps in which the properties of near-critical solvents are utilised, for example as a reaction or crystallisation medium and a chapter is devoted to these important aspects. It is hoped that the work will be found to contain a great deal of specific information of use to those already familiar with this field. However the style of presentation and content is such that it will also be useful as an introduction. In particular it will be helpful to those wondering if this form of separation method has anything to offer for them, whether they are engineers, chemists or managers in industry, or in academic or research institutions.

Available in PDF, EPUB and Kindle. Book excerpt: The use of aromatic plants has been practised since ancient times as is evidenced by records of Chinese, Egyptian, Mesopotamian, Greek and Roman origin; recent findings in Pakistan prove that it goes as far back as 5000 years. Accordingly, the importance and value ascribed to them were always high. Either as a medicine, a foodstuff, a seasoning, a cosmetic or an element of religious rituals the aromatic plant was indispensable. It is not to be forgotten that desire tor the riches of India - spices among which - and the struggle to monopolize the trade of the latter con tributed to the opening of new sea routes, discovering of continents and altering the picture of the known world.

Download or read book Extraction of Essential Oils from Jasmine Flower Using Supercritical Co2 Co solvent Extraction written by Norulshahida Che Din and published by . This book was released on 2006 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pure essential oils are derived from various part of the plant. These essential oils have a very high commercial value due to its properties. They are widely used in the various fields of industries, such as perfumery industries and pharmaceuticals. Conventional technique to extracts this oil such as steam distillation is unsuitable since it induce thermal degradation of compounds in the oils. It is for this reason that the extraction of essential oils using supercritical fluid extraction method is said to be the most effective method. It also can avoid contamination of the oil. This extraction technique employed carbon dioxide (CO2) as solvent due to CO2 is stateless, odorless, non-toxic and chemical inertness and would not contaminate the environment and products. Thus, the material residues can be used without pretreatment. Beside that, the low critical properties make CO2 the most preferable solvent in this technique. The used of co-solvent also affect the extraction of these essential oils because it could modify the CO2 selectivity towards the fragrances compound. This can in turn produce higher quantity of products. For this purpose, two co-solvent had been employed, viz. ethanol and methanol.
