Beskrivning
Introduces the principles that augment the formulation of products free from traditional preservatives by creating a hostile environment for microorganisms without diminishing quality. The text emphasizes that the preservation of a product should be inherent in the formula and examines the use of multifunctional chemicals whose secondary characteristics include germistatic and germicidal qualities.
"This book describes. . .a unique approach to the formulation of dermatological and cosmetic products and the authors should be congratulated for bringing it to the attention of the interested parties. The book provides a well documented bibliography at the end of each chapter with the most recent references. "---American Journal of Pharmaceutical Education
