A Dermatological View—The Future of Allergic Contact Dermatitis as it Pertains to Cosmetics

Following are some aspects of patch testing that require consideration, including the ingredients used, related legislative measures and testing limitations.

Fluorescent Biosensor Reveals Immune System Response

Researchers at Carnegie Mellon University have discovered how immune cells exchange information using a new fluorescent biosensor developed at the university.

Survey Finds R&D to Increase in 2012 With Emphasis On Innovation

A survey conducted by the Industrial Research Institute (IRI) has found that R&D spending is expected to increase in 2012. The company's 2012 R&D Trends Forecast also found that new product development will increase in 2012.

New Perspectives in Emulsion Formation

Previously, the theory explaining emulsion behavior was based on the equilibrium contact angle of the particle at the interface; however, Vinothan N. Manoharan, PhD, and his team at Harvard believe the time allowed for the system to reach equilibrium and the force pushing the particle to the interface are equally as important.

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.

Comparatively Speaking: Patent vs. Trade Secret

In this "Comparatively Speaking," Tony O'Lenick explains the difference between patents and trade secrets, both of which cosmetic chemists will encounter during their careers. This information will assist in determining whether a technology should be patented or maintained as a trade secret.

Properties of O/W Emulsions with Anisotropic Lamellar Phases

In cosmetic and pharmaceutical creams and lotions, fatty alcohols are well-known as viscosity modifiers. In addition, Schulmann and Cockbain found that the stability of oil-in-water emulsions was greatly increased by addition of cetyl alcohol.
