Lacquer Chemistry and Applications explores the topic of lacquer, the only natural product polymerized by an enzyme that has been used for a coating material in Asian countries for thousands of years. Although the human-lacquer-culture, including cultivation of the lacquer tree, harvesting, and the use of lacquer sap, has a long history of more than thousand years, there is very little information available on the modern scientific methods to study lacquer chemistry. This book, based on the results of the authors' 30 years of research on lacquer chemistry, offers lacquer researchers a unique reference on the science and applications of this extremely important material. Covers the chemistry and properties of lacquer, including synthesis of its various components Provides up-to-date analytical techniques for lacquer identification and characterization Discusses possible toxicity effects Outlines new modification techniques for developing higher performance material Presents the history of this versatile coating material that has evolved from its origins in Asian countries over thousands of years
The conceptualization and formulation of skin care products intended for topical use is a multifaceted and evolving area of science. Formulators must account for myriad skin types, emerging opportunities for product development as well as a very temperamental retail market. Originally published as "Apply Topically" in 2013 (now out of print), this reissued detailed and comprehensive handbook offers a practical approach to the formulation chemist's day-to-day endeavors by: Addressing the innumerable challenges facing the chemist both in design and at the bench, such as formulating with/for specific properties; formulation, processing and production techniques; sensory and elegancy; stability and preservation; color cosmetics; sunscreens; Offering valuable guidance to troubleshooting issues regarding ingredient selection and interaction, regulatory concerns that must be addressed early in development, and the extrapolation of preservative systems, fragrances, stability and texture aids; Exploring the advantages and limitations of raw materials; Addressing scale-up and pilot production process and concerns; Testing and Measurements Methods. The 22 chapters written by industry experts such as Roger L. McMullen, Paul Thau, Hemi Nae, Ada Polla, Howard Epstein, Joseph Albanese, Mark Chandler, Steve Herman, Gary Kelm, Patricia Aikens, and Sam Shefer, along with many others, give the reader and user the ultimate handbook on topical product development.
Designed as a guide for the coating formulator and technologist as well as a reference for students, this handbook offers practical information, data, and references needed to understand and solve coating problems.
Document from the year 2016 in the subject Chemistry - Organic Chemistry, , language: English, abstract: This book presents the fundamentals and most recent scenario of varnishes. Components, classification, characteristics and applications of varnishes are discussed in the book. It is written in comprehensive manner. Wood is valuable for structural purpose and decorative purpose also. Wood has plant origin. The wood used for building construction is known as Timber. Forests produce a huge quantity of timber. Cellulose, Hemicellulose, Lignin and other substances are the constituents of wood. Aliphatic compounds, phenols, fats, waxes, terpenes, terpenoids etc. are found in woods. Stilbenes, Tannins, Flavonoids and Lignanas are phenolic compounds available in woods. Coating of varnishes is useful for wood, metal and their derivatives. It is also useful for plastic and masonry. Varnish is a formulation of resinous matter, as copal or lac, dissolved in oil or in alcohol or any other liquid. When a varnish is applied to the surface of wood or metal, it dries and leaves a hard and generally transparent coating. It is a shiny coating which is applied on a floor or furniture. It dries clear and luminous. It gives a hard, lustrous and transparent finish to the surface. It gives furniture, wooden materials, artwork and other objects a glossy look. It also protects the surface. Usually varnish is prepared from resin, solvent and oil. The Medieval Latin root word for varnish is ‘vernix’ that means odorous or fragrant resin. Some varnishes harden immediately as the solvent evaporates. So, it produces a film. The other varnishes harden slowly over a period of time. The process of hardening involves oxidation and polymerization. Shellac, Resin and Lacquer dry immediately. Acrylic and some of the water based varnishes evaporate the water or solvent and dry over a period of time. It is also known as curing process of varnishes. Oil based, polyurethane and epoxy varnishes also dry slowly to hard finish. Generally, the factors like following affect curing process of a varnish: - Temperature - Humidity of atmosphere - Components of varnish. Wood kept outside is normally exposed to big variations of temperatures and weather. It is also exposed to Ultra Violet(UV) rays in the atmosphere. Changes in humidity also affect the wood which results in contraction or expansion of wood. These all factors damage the wood or wooden articles. Hence, varnishes can be used to protect wood and wooden articles.
