Manufacturing problems affecting the industry today are identified, investigated and solved in this practical and engaging technical book. Take advantage of the 50 years of knowledge and experience the author has acquired working in and visiting cosmetic factories around the world, talking to production managers, cosmetic chemists and engineers about a variety of challenging manufacturing problems.
With energy costs expected to increase along with the continuing global warming trend, many large manufacturers of consumer products are already facing demands to reduce their energy consumption. Learn more about LEE to tackle energy issues and significantly reduce processing times.
The pressures and time constraints placed on cosmetic chemists have never been greater. Increased global competition, the ability to produce a wide range of products at a consistently high level of quality, increased batch sizes and manufacturing failures are fully addressed in this book. Discover how to control the quality and stability of emulsion products, optimize emulsion droplet size, understand composition variables and so much more.
This book educates and empowers, providing readers with the tools necessary to meet challenges head-on and manage everyday issues. Discover how to avoid formulating and manufacturing mistakes that have been made by others, in order to save time and expenses in your company. Explore the pages of this book to uncover the exciting and challenging area of emulsion science!
T. Joseph Lin, PhD, is a fellow and emeritus member of the Society of Cosmetic Chemists (SCC). Lin has been working as an independent consultant for the past 32 years, specializing in emulsion technology and process engineering. He has published numerous scientific papers on emulsion technology, rheology and process engineering, and received a number of awards from the SCC, including the International Flavor and Fragrance Award and Literature Award among others, for his research work. In 2001, Lin received the SCC's highest honor—the Maison G. de Navarre Medal Award—in recognition of his contributions to scientific research, including his pioneering work on low-energy emulsification.
“This valuable book summarizes Dr. Lin’s 40 years of experience in the formulation of emulsions for the personal care industry. The tone for the entire book stresses that for successful industrial production, knowledge of the fundamentals is a necessary, though far from exhaustive, basis for the tasks at hand. The variation of quality and composition of different batches of raw materials may cause unanticipated problems, which require the formulator to either gather hard won experience or learn from others. In short, Manufacturing Cosmetic Emulsions takes the reader from the laboratory—where one deals with the fundamental use of compounds with defined structure– and into the industry, where a product is formulated to customer specifications and where problems arise with regard to batch variation in the properties of the raw-materials.
Lin emphasizes the importance of a good quality control program to allow efficient screening of potentially troublesome batches, but also the importance of distinguishing “perfect stability” from “controlled stability,” as the latter is what the customer wants. In the same pragmatic manner, Lin points out that controlled stability may be more difficult to obtain and that camouflaging imperfection by the use of a less transparent container may be the solution. Lin further stresses the importance of microbial and chemical stability, devoting an entire chapter to “Solving Problems and Defusing Time Bombs,” which is useful reading for anyone entering or already within the personal care industry.
Chapters on “Pilot Batches, Scale-Up and Controlling Process Variables,” “Understanding Human Factors,” “Strategies for Production Trouble Prevention” and “Low Energy Emulsification,” along many more, are all filled with useful information of a kind derived of a long life in studying and solving problems in emulsion manufacturing.
This book I not only recommend, but believe it should be mandatory reading for anyone connected with or interested in the personal care and pharmaceutical industries, or of any industry concerned with emulsions.”

"Joe Lin has been teaching cosmetic chemists how to best formulate emulsions for many years. This book focuses on optimizing manufacturing of these products and teaches us many invaluable 'tricks.' I urge all people who are involved in the development or production of emulsions to read this book and learn from his wealth of knowledge."

"This is truly a long awaited book! Ever since the 1980 IFSCC Congress in Venice, when for the first time I read a scientific paper written by T. Joseph Lin, I have continued searching for his new studies on industrial emulsification techniques. His publications have been essential to my successive consulting carrier, when putting in practice his many findings provided me a way to solve the production troubles of customers around the world. My only surprise was that very few people seemed to have read Lin?s work. In my cosmetic courses, my students were always given this information as a precious gift. 'Less is Gain, More is Confusion,' is the motto that leads this book, which is as enchanting as an adventure tale, suggesting a path in the jungle of emulsion formulation strategy and production scaling-up. By reading this book, one recalls the many daily issues of the formulating scientists and technical directors: how to produce the same formula in the most simple and economic way, with the available equipment, by contemporarily saving costs and with a constant outcome of product performances. The Low Energy Emulsification technique is, in my opinion, the most brilliant finding I have read on production strategy, and is here explained in simple terms with even simpler types of demonstration, like particle size and conductivity studies—no complex mathematical formulae, only pragmatic approaches and intelligent reasoning. This book demonstrates how there is no need for complicated instruments, just a wise experimental strategy in order to solve scaling-up problems. It represents a good source of self-identification memories for the skilled reader, and a real valediction for all the technology people in cosmetic factories, where the formulation technology universe is unfolding."
