Although the research actIvItIes of dyestuff chemists worldwide have been influenced to a great extent, in recent years, by the need to respond to a variety of environmental issues associated with the manufacture and application of synthetic dyes and pigments, a significant level of targeted research continues to be devoted to new chemistry aimed at enhancing the technical properties of dyes in commerce. This book is a presentation of various aspects of basic research conducted during the past decade but not reported in the recent review literature. The coverage herein is unique in that it emphasizes systematic approaches commonly utilized in the design and synthesis of dyes and pigments and the required intermediates. While it is well known that certain transition metals are important in the synthesis of technically viable metallized dyes for polyamide and protein fibers, these metals are demonstrated in Chapter 1 also to be effective agents in the regiospecific placement of substituents into azo compounds. The scope and limitations of this chemistry are presented. In other synthetic work, a description of the different processes employed to produce the major families of reactive dyes is presented. In Chapter 4, special attention is given to reactive dyes containing more than one reactive group, and to the more recent developments in the field. The two chapters which follow provide a review of the recent literature pertaining to novel chromophores and dyes for the D2T2 process, respectively.
More than one and a half decades have passed since the last book was published describing developments in the analytical chemistry of synthetic colorants. In the intervening period, the scope and technical capabilities of instrumentation for analysing dyes and pigments has significantly expanded. It is now possible to rapidly resolve a number of problems whose solutions were previously either unattainable or very difficult to achieve. For instance, the unambiguous assignment of all the signals in the proton NMR spectrum of a trisazo direct dye, and the confirmation of the molecular weight of involatile, and, in particular, sulphonated dyes, without derivatisation, are now routine analytical techniques in many laboratories today. In addition, it is now possible to record the NMR spectrum of a dye molecule on less than 1 mg of material, and we are no longer limited to solution spectra, since solid samples can now be routinely analysed in NMR experiments. Whilst not attempting to be all encompassing, this volume is intended to bridge the gap between what was covered in the earlier work edited by Professor Venkataraman and the developments which have since ensued in some key areas. It provides important updates in X-ray crystallography, proton NMR, IR spectroscopy and mass spectrometry, and additionally covers topics such as ESR, micro spectrophotometry and emission spectroscopy.
This simple handbook aims to enable readers to make their own lake pigments or dye their own textiles using dyes from naturally occurring raw materials in a simple way under relatively controlled conditions and using recipes optimised for easy use in the laboratory or indeed the classroom. The book provides the basic principles of dying and lake pigment making (using the term lake pigment in its original, historical, sense indicating a naturally occurring dye precipitated onto a conventional usually white substrate, frequently a form of hydrated alumina) and from these the reader can try modifying the conditions or the amount of raw material, for example, to obtain different results. Suggestions for simple modifications are given. Contents: Introduction Natural dyes and their sources - plants, insect reds and shellfish purple The techniques of dyeing and pigment making - the basic chemistry behind the processes Recipes for dyeing Recipes for pigment making Bibliography

This treatise pertains to dyes composed of a central polymethine moiety and two cyclic terminal subunits. The polymethine linker can be unsubstituted or substituted, and at least one terminal subunit is a heterocyclic system. The classes of compounds reviewed range from classical cyanines, ?rst s- thesized in the 1850s, to hemicyanines, to styryl dyes, to merocyanines, to coumarinpolymethines, andtosquarylium dyesthatweresynthesized forthe ?rst time in the 1960s. These structurally diverse classes of compounds have one commondenominator, namely electronconjugation that involves the t- minalheterocyclic/aromaticsubunitsandthecentralpolymethinelinkerofthe molecule. Such conjugated molecules show absorption and ?uorescence that are a function of the structure of the three moieties. By changing the length and substitution of the polymethine linker and/or the structures of the t- minal moieties, molecules can be designed with absorption and ?uorescence ranging from the blue visible region (> 400nm) to the near-infrared region (> 700nm) of the electromagnetic spectrum. The synthetic developments of the last decade are reviewed and references to older but important work are provided tohelpdesignadye ofinterest fora desired speci?c application.

Cosmetics manufacture is a dynamic and vibrant industry with companies varying from the very small scale, working in their own home, to much larger enterprises. With such variable companies there is the risk of equally variable quality in manufacturing. The International Organization for Standards (ISO) provides guidelines on good manufacturing processes for the cosmetics industry. However, not everyone working in cosmetics has a scientific or engineering backgrounds and understanding and meeting the ISO requirements can be daunting. Whether you are a small business just starting out or an established company looking to expand, Making Quality Cosmetics will guide you through the requirements of the ISO standard. Calling on more than 35 years of experience in the cosmetics sector the author covers every aspect of the manufacturing set up and process, as well as discussing other regulations that may need to be considered, especially in larger facilities. With technical advice ranging from choosing equipment and raw materials, to assessing and auditing contractors this book will help you make sure your products are of the highest quality.

Modern printing is based on digitizing information and then representing it on a substrate, such as paper, pixel by pixel. One of the most common methods of digital printing is through inkjet printers. The process of inkjet printing is very complicated, and the ink used must meet certain chemical and physicochemical requirements including those related to storage stability; jetting performance; color management; wetting; and adhesion on substrates. Obviously, these requirements - which represent different scientific disciplines such as colloid chemistry, chemical engineering, and physics - indicate the need for an interdisciplinary book that will cover all aspects of making and utilizing inkjet inks.This book provides basic and essential information on the important parameters which determine ink performance. It covers not only the conventional use of inkjet technology on graphic applications, but also the extension of this method to print various functional materials, such as the use of conductive inks to print light-emitting diodes (LEDs) and three-dimensional structures. Thus, the book will serve a large community: industrial chemists who deal with ink formulations and synthesis of chemicals for inks; chemical engineers and physicists who deal with the rheological and flow properties of inks; and researchers in academic institutes who seek to develop novel applications based on inkjet printing of new materials.

'As perfume is an art, it should be revealed to artists' was the passionate belief of the author, the renowned French cosmetic chemist R-M GattA(c)fosse, who coined the term 'aromatherapy' and was instrumental in its development. In this volume GattA(c)fosse set out to restore the fortunes of the French perfume industry after World War II by educating a new generation in the artistic principles of perfumery and cosmetology as well as in chemical and technical matters. He explains how to handle the raw materials of perfumes and cosmetics, gives the formulas for classic formulations like chypre, amber, vetivert and jasmine along with methods of preparation, and encourages readers to develop their own perfume formulas, aromatic creativity and 'nose'. In the second part of the work GattA(c)fosse presents cosmetology formulas for beauty creams, lotions, rouges, sun and sport creams, and hair and nail products. The great value of the work lies in the formulas it contains which have been largely forgotten today, and which can be recreated or interpreted with little difficulty. Intended as a resource for interested laymen and professional perfumers and cosmetologists, this is an inspirational text by the man who changed the nature and smell of modern cosmetics and perfumes.

Nanotechnology is key to the design and manufacture of the new generation of cosmetics. Nanotechnology can enhance the performance and properties of cosmetics, including colour, transparency, solubility, texture, and durability. Sunscreen products, such as UV nano-filters, nano-TiO2 and nano-ZnO particles, can offer an advantage over their traditional counterparts due to their broad UV-protection and non-cutaneous side effects. For perfumes, nano-droplets can be found in cosmetic products including Eau de Toilette and Eau de Parfum. Nanomaterials can also be used in cosmetics as transdermal drug delivery systems. By using smart nanocontainers, active compounds such as vitamins, antioxidants, nutrients, and anti-inflammatory, anti-infective agents, can be delivered effectively. These smart nanocontainers are typically related with the smart releasing property for their embedded active substances. These smart releases could be obtained by using the smart coatings as their outer nano-shells. These nano-shells could prevent the direct contact between these active agents and the adjacent local environments. Nanocosmetics: Fundamentals, Applications and Toxicity explores the formulation design concepts and emerging applications of nanocosmetics. The book also focuses on the mitigation or prevention of their potential nanotoxicity, potential global regulatory challenges, and the technical challenges of mass implementation. It is an important reference source for materials scientists and pharmaceutical scientists looking to further their understanding of how nanotechnology is being used for the new generation of cosmetics.
Volume 3, like the preceding volumes, focuses on the diversity of surfactants, both in terms of chemical structure and physico-chemical / surface active properties. These properties may be predictable for simple molecules but, for most commercial surfactants (which may be regarded as multi-component blends), this is not so easy. Yet it is important to develop a greater understanding of the interactions within a multi-component mixture, in order to select the most appropriate product for a particular application in which a combination of surface active properties is required. A special feature of this volume is the initial chapter, in which the end uses of surface active agents are classified by industrial sector and the surfactant properties required for each application are presented in detail. The result is a unique guide to the influence of chemical structure on performance in end use, highlighting the benefits of particular surfactants and illustrating how some of the newer classes of surfactant may overcome the deficiencies of previously used products.
