Characterizing Nanoemulsions Prepared by High Pressure Homogenization Under Various Emulsifying Conditions
By: Ruandro Knapik and Maria Carolina Rocha dos Sa…
The present study examines formulations prepared using similar oil fractions and differing emulsifier systems and process parameters to determine why their behaviors differ. Results showed that ethoxylated emulsifier systems were the most stable, and that beyond a certain number of cycles, high pressure homogenization did not significantly improve the quality of the product.

Controlling Hydroxyl Radical Formulation in TiO2 Sunscreens
By: Nai-Fang Chang and Chang-Chin Kwan, Providence…
Titanium dioxide (TiO2) is an effective sunscreen agent but its rutile form may produce hydroxyl radicals upon exposure to sunlight. Thus, the authors use salicylic acid as a capture agent to examine the development of free radicals in solutions or creams containing TiO2. They also explain how the choice of emulsion may reduce free radical generation.

Comparatively Speaking: Higher vs. Lower Levels of Surfactant Silicone
By: Anthony J. O'Lenick, Jr., Siltech LLC
Alkyl silicone compounds can be effective in oil-based systems, as they are soluble (i.e. clear when added) and lower surface tension when added to oils. They first lower surface tension by increasing their concentration at the interface, then they form micelles.

Palm-derived Dihydroxystearic Acid for Sensory and Technical Applications
By: Rosnah Ismail and Hazimah A. Hassan, Malaysian…
Dihydroxystearic acid (DHSA), derived from palm oil- or palm kernel oil-based oleic acid, offers interesting applications since its addition to oily phases and wax gels affects flow and spreading properties. Moreover, it interacts with the surfaces of pigments and fillers, improving color development as well as sensory attributes, as shown here.
