Researchers Suggest New Way to Look at Manufacturing Emulsions
Researchers at Harvard's School of Engineering and Applied Sciences (SEAS) have discovered that stabilized emulsions may take months to years to reach equilibrium. This research has important implications for the manufacturing processes used in pharmaceuticals, cosmetics and foods, among other chemical industries.

Silicone Safety and the Cosmetic Industry
By: James Lambert, PhD NuSil Technology LLC
The use of silicones in personal care products continues to expand because of the unique performance attributes they provide and their well-established record of safety. As a result, progressively larger volumes of silicones are being released to the environment, and interest in their life cycle has increased. The present article summarizes relevant fundamental chemical and physical properties of silicones and how these relate to material performance, safety and environmental fate.

Nanocrystal Liquid Identification
By: Katie Anderson (Schaefer), Cosmetics & Toiletr…
Watermark Ink (W-Ink) utilizes chemical and optical properties of nanostructured materials to distinguish liquids based on surface tension. The nanostructured material is called an inverse opal, which is a layered glass structure with an internal network of ordered, interconnected air pores.

Improving the Solubility of Benzoyl Peroxide: A Review
By: James Ziming Sun, PhD, Diversapack of Californ…
In this review, the authors examine studies relating to the solubility of BPO. The clinical trials discussed show that compared with suspended BPO, BPO solubilized by dimethyl isosorbide reduced P. acnes and decreased both inflammatory lesions/irritation and the emergence of antibiotic-resistant P. acnes strains. This reveals the importance of solubilizing BPO for improved efficacy and safety.
