Making Quality Cosmetics: Good Manufacturing Practice and ISO 22716:2007
Making Quality Cosmetics:
Good Manufacturing Practice and ISO 22716:2007 By Alastair J Gilchrist
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.
