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.

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 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.
