Natural and Synthetic Waxes A compilation of all relevant information for the production and use of waxes in technical applications Waxes are among the oldest organic substances used by mankind. Before all others, beeswax is known to have played a role in human history for thousands of years. But over time, many other wax species have been detected and exploited, and prepared for different utilizations. Today, we possess knowledge of a great variety of different types of waxes. Unfortunately, there still is no broadly accepted definition of a wax: for the relatively few wax chemists, waxes are usually defined by their physico-chemical properties more than by their chemical constitution. Waxes are not uniform but oligomeric and polymeric substances, not simply describable with a chemical formula. The realm of waxes encompasses fully or partly natural, refined, partly or fully synthetic products, which can be extended by “wax-like” products which do not fulfil all definition criteria. Waxes are offered in different forms like pellets, granules, powders, or micropowders. Their number of technical applications runs into thousands. However, waxes in most cases are just adjuvants or additives, and with few exceptions like candles not known to a broader public. Only few publications over the last decades tried to present a more comprehensive overview of heir chemistry, chemical composition, their physical and analytical properties, their applications, and their sometimes astonishing history. Based on personal experience and expertise, the authors intend to present an overview on the main classes of waxes, their origin, history, future, and potential fate. Economical aspects like market size and development, ecological impacts and challenges, and regulatory issues are also addressed. Waxes are indispensable products in everyday life and in industry and technology, though mostly not even visible or distinguishable to experts. They deserve more than the role of a “poor cousin” in chemistry and technology.

Basic Dental Materials is the new edition of this extensive guide to materials used in dentistry. The book has been entirely reorganised, with substantial revisions in each chapter incorporating the latest developments and research findings, and new colour illustrations have been added. This book is divided into seven sections, the first covering the structure and properties of dental materials, including electrochemical and biological properties. Further sections cover specific groups of materials, including direct restorative materials, endodontic materials (new to this edition), impression materials, materials and processes in the dental laboratory, alloys, and indirect restorative and prosthetic materials. The chapter on dental ceramics in the final section is entirely revised to reflect the significant advances in this technology since the previous edition. Basic Dental Materials provides a practical approach to the selection and use of modern dental materials, with guidance on preparation for indirect restorations such as crowns, bridges and inlays. Enhanced by 645 images and illustrations, this comprehensive book will bring the knowledge of dental students and practising students firmly up to date.

Polishes typically contain a lot of abrasives, rinsing agents and organic solvents. Protectants typically contain neither abrasives nor rinsing agents, less organic solvents than the two other product types and a lot of protectant. Polishes are used to maintain a glossy finish on surfaces as well as to prolong the useful lives of these surfaces. Polishes can be described in terms of their physical form, carrier system, ability to clean, and durability. Physical forms of polishes include pastes, pre-softened pastes (non-flowing emulsions), liquids, and gels. Polishes beautify and protect by coating or refinishing surfaces. Waxes are used as finishes and coatings for wood products. Waxes are also used in shoe polishes, wood polishes, and automotive polishes, as mold release agents in mold making. Furniture polish value sales are expected to reach US$ 13,101.3 mn by 2027, expanding at a CAGR of 5.0%. Shoe polish protects the shoes from moisture, water, and becoming hard. It provides the shoes with a waxy coating and a shine. Shoe polish market is concentrated in the urban areas. The global shoe polish market is projected to grow at a CAGR of 2.75% over the forecast period of 2019-2025. The global metal polish products market has been registering rapid growth, owing to the use of different metal alloys in machinery, furniture and other metal products due to their cheaper cost and high efficiency. Globally, the metal polish market has been witnessing significant growth, owing to the rise in the demand for cleaning and polishing products. The book contains formulations and manufacturing process of auto polish and wax products, furniture polish, marine polish, metal polish and shoe polish, their marketing strategies, BIS specification, directory section, plant layouts and photographs of machinery with supplier’s contact details. A total guide to manufacturing and entrepreneurial success in one of today's most wax and polish industry. This book is one-stop guide to one of the fastest growing sectors of the wax and polish industry, where opportunities abound for manufacturers, retailers, and entrepreneurs. This is the only complete handbook on the commercial production of wax and polish products. It serves up a feast of how-to information, from concept to purchasing equipment
