Dielectric Constant to Develop Clear Sunscreens for Wet Skin
Feb 21, 2014
Sunscreen sprays have gained momentum due to their ease of application. However, while they appear clear on dry skin, they often turn cloudy and white when applied to wet skin. Here, the authors present a formulating approach based on the dielectric constant of esters and level of alcohol in formulations to produce anhydrous sprays that appear clear on wet skin.
Dolichos Cell Culture Extract for Protection Against UV Damage
Nov 15, 2013
Dolichos biflorus cell culture extract is evaluated here for its effects on skin cells. Results indicate the extract provides strong anti-inflammatory, antioxidant and protective properties for skin, and the ability to repair UV-induced damage. Further, this work reinforces that cell culture systems are efficient biofactories to produce natural and effective compounds.

Titanium Dioxide Particle vs. Sun Protection Performance
May 1, 2013
The article compares the performance of titanium dioxide as a UV filter in cosmetic formulations as a function of its primary particle size. It was found that with increasing primary particle size, even below 100 nm, the effectiveness of the inorganic (mineral) UV filter was clearly reduced.
