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.

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.

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.

Commercial use of squalane has been constrained by an inconsistent supply and resulting price volatility, but modern biotechnology has been able to leverage enzyme-catalyzed chemical reactions found in nature coupled with traditional chemical processing steps to create a high-quality source of renewable squalane.

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.

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.

This article reviews studies to diagnose allergic contact dermatitis due to fragrance, including a patch test designed to measure such. Limitations of patch testing, the relevance of fragrance concentration in products, use testing of common consumer products, and dermatologist recommendations to manage fragrance contact allergy also are discussed.

There appear to be no published studies on facial aging in Russian women, despite clear interest from the industry in this market. In order to formulate products, it is necessary to understand the end consumer. This article therefore explores a recent study of 203 Russian women and describes their aging specificities versus other, more studied Caucasian populations.

Damage to the hair shaft can lead to the breakdown of proteins from the hair, which can provide an early diagnostic for damage before it is manifested at the macro-structural level. Mike Davis will explore this approach during the Cosmetics & Toiletries Summit this June.
