Addressing both the philosophy and science of preservation, Preservative-Free and Self-Preserving Cosmetics and Drugs emphasizes that the preservation of a product should be inherent in the formula itself...explains the rationale for providing product protection by reducing or eliminating classical preservatives...highlights the desirability of reducing the levels of preservatives in cosmetics...discusses the replacement of irritating or sensitizing agents...describes the refinement of formulas to eliminate preservatives...considers the impact of preservative-free and self-preserving products on global markets and international regulations...and more.
The eleven contributions to this volume address both the philosophy and science of preservation, including the following topics: the rationale for providing product protection by reducing or eliminating classical preservatives; the desirability of reducing the levels of preservatives in cosmetics; the replacement of irritating or sensitizing agents; the refinement of formulas to eliminate preservatives; and the impact of preservative-free and self-preserving products on global markets and international regulations, as well as such concrete matters as the effect of acid Ph on microorganisms, the roles of surfactants in self-preserving cosmetic formulas, fatty acids and esters as multifunctional components, biomimetic phospholipids, aroma chemicals as preservatives, chelating agents as preservative potentiators, and the role of packaging in product preservation.

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.
