Sustainable Ingredient Science: Amazonian Aguaje and Pequi Palm Oils

The food and nutrition supply chain is often the first entry for “super plants” from the Amazon to the market, but other applications are increasing, especially in personal care and cosmetics. The present article profiles two Amazonian palm oils, aguaje and pequi, in terms of their sustainability, chemistry and application.

Modeling the Dynamics of Hair Movement

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.

Formulators Can Avoid Quality Disasters

There are a number of things that cosmetic chemists can do to avoid problems in production and ultimately in the marketplace. In the laboratory, almost anything is possible, but production life is very different.

IFSCC 2014 Explores Social, Psychological and Sensorial Aspects of Beauty

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.

Practical Foam 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.

Assessing Beauty By Facial Topography, Color and Symmetry

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.

Deriving Renewable Squalane from Sugarcane

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.

3D Printing 'Popping Up' in Personal Care

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

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.

Science-based Skin Care in Demand

Science-based skin care is not new to the industry, but according to market research firm Diagonal Reports, it's a new demand from consumers. Speakers at the C&T Summit will address means to meet this demand on June 26 and 27. Register now!

Understanding Fragrance Allergy, Is Fragrance-free Always Necessary?

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.

Penn State Develops 3D Model Linking Facial Features to DNA

Researchers at Penn State have developed a three-dimensional model that illustrates connections between the shape of the human face and DNA.
