Feb 21, 2014Katie Anderson, Cosmetics & Toiletries

Betty Yu, PhD, and her team at Living Proof have entered the skin care market with a flowable silicone polymer technology that cross-links upon activation to form a breathable, invisible film designed to contour and tighten the eye area, reducing the appearance of under-eye bags.

Armoring Enamel: New Paradigms for Combating Dental Decay

Feb 21, 2014Steven Isaacman, PhD, and Michael Isaacman, PhD, Nanometics LLC; and Kent Kirshenbaum, PhD, and Peter Smith, New York University

To protect enamel, new mechanisms in classic oral care continue to be uncovered, while modern advances mimic and enhance natural protective systems. New approaches to enamel repair include augmenting natural remineralization by creating reservoirs of ions and applying saliva biomimetics. Such technologies, described here, represent significant advances for repairing and protecting teeth noninvasively.

Peptidomimetics for Cosmetic Applications

Sep 1, 2013Steven Isaacman, PhD, Nanometics LLC; Michael Isaacman, University of California Santa Barbara; and Sung Bin Y. Shin, PhD, Avon Products

Peptidomimetics, or synthetic bioactive peptides, have been developed that mimic the biological functions of peptides and proteins but overcome many of these challenges and limitations. Further, due to their wide range of activity, synthetic feasibility and ease of handling, they have played a vital part in biological research. This column will discuss the potential application of these short chain oligomers in cosmetics and personal care.

Chinese Licorice Extract for Anti-aging, Antibacterial and Breath-freshening Effects

Aug 1, 2013Stefan Gafner, PhD, Tom’s of Maine

This article reviews in vitro studies that have found Chinese licorice extract to impart potent antibacterial and soothing properties, which make it an interesting candidate for applications in oral and personal care. Further, a clinical study is described in brief, assessing the ability of a supercritical CO2 extract from Chinese licorice to impart breath-freshening properties.

Caprylyl Glycol/Phenethyl Alcohol Blend for Alternative Preservation of Cosmetics

Aug 1, 2013Paola Ziosi, Stefano Manfredini, Alberta Vandini and Silvia Vertuani, University of Ferrara; and Massimo Fraternali, Akema Fine Chemicals

In recent years, the safety of traditional preservatives has been called into question. Therefore, there is a need for alternatives that are effective, safe and sustainable—and that are non-controversial. In response, the present work investigates a mixture of caprylyl glycol and phenethyl alcohol, which is shown to provide antimicrobial activity in various skin and hair care formulations.
