Molecular Modeling of Skin care Products: Application for the Design of Pepidomimetics
By: Jean-Francois Nicolay, PhD, Exsymol S.A.M. and…
Molecular modeling has been used in the pharmaceutical industry for years to predict how a new molecule may work based on research conducted with molecules of a similar structure. The cosmetics industry has also begun to use this technology to predict the behavior of new molecules on skin and in skin care applications.

Using Ultrasound Scanning to Characterize Colloidal Particles
By: Malcolm Povey, Procter Department of Food Scie…
Changes in the macroscopic nature of aqueous or colloidal formulations can lead to changes in the odor, appearance or feel of a product. Data presented in this article demonstrates ultrasound scanning to determine formulation shelf life and monitor product quality.

Three Decades of Patch Testing: Trends in the North American Populace
By: Shawn Nguyen; Thao Dang; Cora MacPherson, PhD;…
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.

Green Formulations: Not All Components Are Equal
By: A. Cristoni, G. Maramaldi and C. Artaria, Inde…
In the consumer’s mind, a natural or green cosmetic is automatically safe; however, the safety, quality and efficacy of botanical ingredients used in formulations need to be carefully assessed. Stability is also an important issue. Current research is directing analyses of final formulations to evaluate not only their cosmetic raw materials, but also their active materials.

Research Pathways to Photostable Sunscreens
By: Craig Bonda, The HallStar Company
This article provides a visual depiction of pathways that UV filters undergo when exposed to solar radiation; such pathways often lead to photo-instability. A fluorescence technique is described that has led the author to identify compounds that preserve photostability in a novel manner— by quenching the UV filter’s singlet excited state.
