As one might expect from an event centered around beauty and staged in Paris, the 28th Congress of the International Societies of Cosmetic Chemists (IFSCC) was nothing less than fabulous. However, the glamour and fanfare was deeply rooted in science.

Assessing Beauty By Facial Topography, Color and Symmetry

Oct 1, 2014

The notion of “aging gracefully” no longer applies, as consumers are constantly judging each other’s facial features to assess their beauty. Here, based on recent studies, it is suggested that facial topography, symmetry and color dictate those assessments. While the cosmetics industry can lessen some of these factors, some are a result of biology or lifestyle.

Practical Foam Science

Sep 23, 2014Steven Abbott, PhD, Steven Abbott TCNF Ltd., Ipswich, and University of Leeds, West Yorkshire, UK

Foam science can be confusing, so the temptation is to formulate by trial and error. However, understanding the science behind key aspects of foam—i.e., elasticity, DLVO Theory stability, Ostwald ripening, draining and antifoams—and applying this will fast-track foam development. These concepts are detailed here.

May 16, 2014Rachel L. Grabenhofer, Cosmetics & Toiletries

Three-dimensional (3D) printing is popping up in many fields, including in cosmetics and personal care development; from behind the scenes, in R&D package concept labs, to presentations at in-cosmetics and the April SCS Symposium—even at home, in one former Harvard student's printable cosmetic device concept.

R&D Spending: 'Investment' vs. Expense

May 7, 2014

It's not news that top-performing companies are putting resources into R&D. Interestingly, however, according to the U.S. Commerce Department, if R&D spending were treated as an investment rather than an expense, the overall growth of gross domestic product could be much higher.
