This chapter discusses the historic and current criteria for the analysis of cosmetic talcum powder and the finding the components of the talcum powder in human tissues. It describes how technicians and scientists have looked in the past for these components and how they should be looked at properly today. Within the chapter it has been shown that it can be complicated, especially when the tools and the methods used are not adequate or sensitive enough. It also goes on to describe methods for analysis that are sensitive enough in both mineral analyses and in human tissue. It also defines the terms that are necessary to use for inclusion of structures based on the scientific knowledge we have today not confused with what either industry or their defenders are trying to use to confuse or defend their positions.

This chapter describes some of what is known about the effects of talc as cosmetic or pharmaceutical talcum powder on the pleura and other organs of the human body. It further describes some of the already known mechanisms of how it interacts with human cells and tissue to cause diseases, specifically in the pleura. The effects of talcum powder are well established that the range of diseases include clinical or subclinical inflammation, granulomatous disease and tumors, in the pleura mainly mesotheliomas. Also included are some preliminary evidence indicating what happens in vitro with macrophages in response to talc morphologically and the consequences following the treatment with the release of factors such as chemokines, cytokines and oxidants.
