A Dermatological View: Tandem Irritants With Synergistic, Additive or Quenching Effects on the Skin
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.

UV Transmission Assessment: Influence of Temperature on Substrate Surface
This work evaluates the impact of temperature on test substrate surfaces during the application, spreading and drying steps of the in vitro method to measure ultraviolet (UV) transmission. The authors work in a range between 20°C and 35°C, and demonstrate that controlling temperature is a key test parameter that should be strictly controlled to ensure reliability.
