This report evaluates the trends in the results of patch testing. The patch test reactions were surveyed retrospectively. The results were statistically compared between 1970 and 2002 because appropriate interpretation of the numbers has public health opportunities.

Welcome back to a continuing discussion regarding the new Registration, Evaluation and Authorization of Chemicals (REACH) regulation and its impact on chemical testing. It is the purpose of this series of articles to provide an overview of these existing validated in vitro methods, as well as new methods that are being considered for validation.

Using a texture analyzer to measure the tightness of the skin before and after the application of selected treatments, the authors demonstrate the potential of texture analysis instrumentation in testing the efficacy of skin care products and substantiating skin tightening claims.

Personal care efficacy tests are known to test the physical effects or toxicity of products, often omitting more abstract and possibly equally as important factors such as well-being.

In this article the results of six published tandem irritation studies are evaluated; possible mechanisms and clinical ramifications, albeit complex, are discussed. The clinical relevance of tandem irritation among cosmetics users and in many occupational settings appears obvious and suggests the need for further studies clarifying its principles and mechanisms.

The authors of the REACH directive had the foresight to recognize the impact of such a large amount of testing on animal use and mandated that in vitro testing methods should be used as animal testing alternatives whenever possible.

The rheology of a pre-neutralized, hydrophobically modified acrylic polymer was investigated by dynamic mechanical measurements using this methodological approach to establish its viscoelastic profile and stability in formulations. Properties of several polymer-containing emulsions were studied and their particle size distribution investigated by laser diffraction.
