The dynamics of hair movement are of particular interest to product developers because they are important to consumers. In relation, computer animation and 3D modeling expert Norman Badler, PhD, of the University of Pennsylvania, will discuss ways to model the dynamics of hair movement during the Cosmetics & Toiletries Summit.

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.

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.

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.

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.

To optimally treat acne, an accurate severity assessment is required1 and while visual assessments have relied on text descriptions, lesion counting and photographic methods, an ideal grading system would be more accurate and reproducible. Further, its ease of use, and time and monetary costs are also important. Here, the authors consider different approaches for improved acne assessments using photography.

Demands for innovation and nature in personal care products have, until now, experienced parallel growth according to consumer perception; i.e., the need for efficacy and the need for purity. Considering these diverse views, this article explores how it is possible to create products that satisfy both via sustainability; bringing natural sourcing to ingredients that are innovative and scientifically proven.

This paper reviews the knowledge and nature of the harvest practices for the octocoral Pseudopterogorgia elisabethae. P. elisabethae extract has been used for nearly two decades in cosmetics and preparations for skin benefits, and a review of the harvest provides product developers with an interesting case study of the harvest of a marine resource.
