Cellulosic Propylene Glycol Production

Walter Trahanovsky, PhD, a professor at Iowa State University's department of chemistry, and his team have developed a method to convert cellulose to glucose using pressure and high temperatures, but he was surprised to find the method also produced ethylene glycol and propylene glycol—two high value chemicals, one a major component in skin care products.

Assessing Use of Gold Nanoparticles

Gold nanoparticles have a wealth of pharmaceutical and medical uses. Notably, the ability of these nanoparticles to absorb light and turn this light into heat has put them at the center of ongoing cancer studies exploring their efficacy in destroying malignant cells.

Signaling Skin pH with Indicator Dyes

Gerhard Mohr, PhD, head of the sensor materials group at The Fraunhofer Research Institution for Modular Solid State Technologies (EMFT), has developed dyes for wound dressings that change color when they detect infection. Interestingly, initial research for this wound-healing application originated in the water treatment field.

Sonically Infusing Eye Products

Many mothers have taught their daughters to apply creams, lotions and serums on the eye area using a light dabbing motion. Studying this motion, Robb Akridge, PhD, developed a device to sonically infuse eye products into the skin.

Literature Review—Terahertz Repair, Notch Signaling and Hydrangea

Following is a sampling of recent scientific literature as assembled by Rachel Grabenhofer, editor of Cosmetics & Toiletries, which was found to have potential impact on personal care.

In Sight—Diet for Better Skin Health

Paula Simpson, executive director of Isocell North America, firmly believes in “feeding the skin from within.” As a nutritionist, Simpson has made a career of advising consumers to follow a healthy diet and supplement it with nutraceuticals; more recently, she became involved where nutraceuticals and cosmetics meet—in nutricosmetics.

Spin-coated Layers for Nano Film Strength

Daeyeon Lee, PhD, and Jacob Prosser, along with fellow researchers from the University of Pennsylvania, were investigating the manipulation of nanoparticle films through spin-coating conditions when they discovered a method to prevent cracks in films for solar cell coatings, and possibly for cosmetics.

Silencing RNA for Cosmetic Effects

RNA interference (RNAi) is a gene-silencing technique that inhibits gene expression by causing the intracellular degradation of mRNA molecules. Since first reported in 1998, RNAi has sparked a revolution in molecular biology and has been employed in a myriad of biological contexts for the systematic evaluation of gene function.

Literature Review—Oxidation, Microdevices and Butterfly Pigments

Cosmetics R&D is constantly inspired by peripheral fields. This new “Literature Review” column therefore gives readers an overview of emerging technologies with potential for use in personal care. It will rotate monthly with the regular “In Sight” column.

Theobromine for Tooth Decay Prevention

While it may help to protect teeth from decay, fluoride at high levels also has been reported to irritate the gastrointestinal tract and some manufacturers have formulated products without it. However, toothpastes without fluoride are not providing any real benefit beyond cleansing, says Arman Sadeghpour, PhD, who, by chance, stumbled across another raw material that exhibits better anti-cavity efficacy than fluoride without adverse health effects.
