Molecular Modeling of Skin care Products: Application for the Design of Pepidomimetics
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.

‘How Did THAT Get in There?’ Identifying Particulate Contamination in Products and Packaging
Particulate contamination and discoloration may occur in products due to foreign materials introduced via raw materials or during the manufacturing process. Agglomeration or reactions between ingredients and packaging components also are possible sources. The identification of contaminants and their origin, described here, is therefore critical so that future incidents can be prevented and safety or regulatory concerns can be addressed.

Soft-focus for the Selfie-obsessed: Eye Tracking to Improve Color Formula Development
In cosmetics, soft focus refers to the blurring of light to immediately correct the appearance of wrinkles and skin imperfections. This parameter can be affected by the refractive index of the emollients used, as well as formula volatility and the dispersion of fillers. The use of eye tracking, described here, can help the formulator quickly select the best-performing formulas.

Fluorescence Laser Scanning Confocal Microscopy to Assess the Penetration of Low Molecular Protein Hydrolyzates Into Hair
The present study uses confocal laser scanning fluorescence microscopy to assess the penetration of protein hydrolyzates into hair. While higher amounts of protein were found in the cuticle, still significant quantities were observed in the cortical parts of hair, and this penetration was enhanced by longer incubation times.
