Scientists Develop Natural Substance Combination to Help Prevent Skin Cancer
Scientists at The University of Texas Health Science Center have reported that a combination of resveratrol, grape seed extract, calcium D-glucarate and ellagic acid may suppress damage that can cause skin cancer. The scientists believe that this research can be used in the future to develop supplements, creams and sunscreens to prevent skin cancer.

Variations in Pigmentation and Ultrastructural Skin Differences Among Ethnic Groups
By: Rupa Pugashetti, MD, Santa Clara Valley Medica…
As formulators create products for varying ethnic backgrounds and with diverse skin types, an understanding of differences in pigmentation and skin structure and function becomes more important. This column reviews recent studies on the structural, genetic and ultraviolet (UV)-responsive differences in skin pigmentation to allow the formulator to create successful products for varying ethnicities and to accurately measure pigmentation.

Damage Control
By: Rachel Grabenhofer, C&T magazine
The typical overall summer experience for me—i.e., a little sunburn; lots of dry, damaged hair; and maybe a slushy—strongly coincides with this edition of Cosmetics & Toiletries magazine in that product developers have devised means of damage control for consumers like me.

Au Naturale Nanoparticle Sun Protection
By: Katie Schaefer, C&T magazine
In 1876, Charles Darwin observed the secretion of yellow matter from the rootlets of ivy. Little was known about the material until 2008, when Mingjun Zhang, PhD, an associate professor of biomedical engineering at the University of Tennessee, and his research team found nanoparticles in the yellow matter.

Environmentally Responsive Nanoparticles for Delivery as Assessed via Light Scattering and Near-infrared Imaging
By: Andrew Harper; Steve Tonge, PhD; Lisa Makein, …
Lipid-based nanoparticles were developed to respond to environmental stimuli and used as site-directed delivery systems. Through Dynamic Light Scattering (DLS), the self-assembly of these 10–40 nm particles was observed. In addition, the penetration of the particles through the stratum corneum was monitored in vivo using a novel Near-infrared Chemical Imaging (NIR-CI) technique.

Silicon Microspheres as UV, Visible and Infrared Filters for Cosmetics
By: Isabelle Rodriguez, PhD, Roberto Fenollosa, Ph…
Silicon microspheres are described as UV, visible and infrared (IR) radiation filters. Parameters of these spheres including shape, smoothness, refractive index and size are examined for their potential benefits in cosmetic formulations. Finally, the ability of the spheres to block IR radiation is evaluated for thermo-regulatory effects.

Meeting the UVA Challenge: Inorganic-only Sun Protection
By: Paul Staniland, PhD, and Julian P. Hewitt, Cro…
The production of a range of titanium dioxide-based dispersions is explored to provide enhanced UVA protection, in comparison with ultrafine titanium dioxide. Formulations containing these dispersions as the only active are shown to achieve a UVA protection factor that is 1/3 of the labeled SPF value, thus meeting European Commission recommendations.

Assessing the Targeting Conditioning Performance of Cationic Polymers
By: Paquita Erazo-Majewicz, PhD, John A. Graham, P…
The distribution of a conditioning shampoo’s cationic polymers and silicone oils along the hair fiber defines its performance. Therefore in the present paper, researchers conduct spectroscopy and microscopy measurements to assess the polymer and silicone deposition of various conditioning systems on hair fibers, the results of which are used to compare efficacy.
