Download or read book pH of the Skin Issues and Challenges written by C. Surber and published by Karger Medical and Scientific Publishers. This book was released on 2018-08-21 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of expressing acidity as the negative logarithm of the hydrogen ion concentration was defined and termed pH in the beginning of the 20th century. The general usefulness of the pH concept for life science was recognized and later gained importance to analytical research. Reports on results of pH measurements from living skin established the term acid mantle - the skin's own protective shield that maintains a naturally acid pH. It is invisible to the eye but crucial to the overall wellbeing of skin. Chronic alkalization can throw this acid mantle out of balance, leading to inflammation, dermatitis, and atopic skin diseases. It is therefore no surprise, that skin pH shifts have been observed in various skin pathologies. It is also obvious that the pH in topically applied preparations may play an important role. Optimal pH and buffer capacity within topical preparations not only support stability of active ingredients and auxiliary materials, but may also increase absorption of the non-ionized species of an acidic or a basic active ingredient. They may even open up opportunities to modify and "correct" skin pH and hence accelerate barrier recovery and maintain or enhance barrier integrity. Further efforts are needed to standardize and improve pH measurements in biological media or pharmaceutical/cosmetic vehicles to increase and ensure quality, comparability, and relevance of research data. In this volume, we present a unique collection of papers that address past, present and future issues of the pH of healthy and diseased skin. It is hoped that this collection will foster future efforts in clinical and experimental skin research.

Download or read book Soils and Environment written by Steve Ellis and published by Routledge. This book was released on 2002-09-26 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils represent the result of a complex set of interacting processes and are an integral component of the environment. Yet soils remain the most undervalued and misused of the Earth's resources. This work examines the fundamental importance of soils. Combining practical analysis and interpretation with a theoretical approach, the authors discuss the properties of soils, debate the environmental factors that influence their development, and address their resulting spatial characteristics on a global scale. Examining the impact of environmental controls on soil formation this book also analyzes the role of soils as components of natural environmental systems, and soil-human interactions. A glossary of terms aids the less scientific reader. Adopting macro and micro-scale, pure and applied, spatial and temporal, and natural and human related approaches, this book offers an understanding of soils within an environmental context. As environmental problems, such as pollution, acidification, erosion and climatic change become matters of greater concern, this work offers an understanding for readers across a spectrum of environmentally-related subjects.
