Compass—Best Foot Forward
By: Rachel L. Grabenhofer
From an insider’s view, safety testing is an assumed step in the development of any product on the market. This puts the pressure on analytical and quality control efforts behind the scenes to ensure that ingredients and products meet or exceed expectations. In doing so, theoretically, no one else has to give it a second thought. For those who must give it considerable thought, this edition features two articles on testing, among other topics.

Large-scale Screenings of Botanical Ingredients: Challenges and Opportunities
By: Patricia da Luz Moreira, PhD, Natura Inova&cce…
Botanical ingredients are interesting for their unique and complementary chemical diversities yet they are criticized for these very traits, which make quality assurance, reproducibility and good phytochemical characterization—required for successful high throughput screening, difficult. This article discusses these challenges as well as the benefits of large-scale screenings of botanical extracts that are currently used or developed for cosmetic product development.

Narcissus Tazetta and Schizandra Chinensis to Regulate ‘Youth Gene Clusters’—An In vitro Analysis
By: R. Gopaul; D.G. Kern; H.E. Knaggs, PhD; and J.…
A blend of Narcissus tazetta bulb and Schizandra chinensis fruit extracts was developed for anti-aging benefits and tested for efficacy on a human skin equivalent. Results indicate it regulates the functions of youth gene clusters by increasing the activities found in younger skin and reducing the activities found in aging skin specific to structure, hydration, cellular proliferation and pigmentation.

A Novel Method to Measure and Pre-select Functional Filler Pigments
By: Miriam Becker, Christoph Schmidt, PhD, Veroni…
Functional filler pigments play an important role in adjusting optical properties such as transparency and soft focus effects in cosmetics. However, their suitability for specific formulas is not apparent until time-consuming tests using many different fillers have been conducted. Therefore, a new method to predetermine the soft focus effects of functional filler pigments is described here.

New method to Reproduce In vitro Cosmetic Product Photostability Findings
By: Marc Pissavini, PhD, Adeline Baud, Stéphanie M…
The present article describes a reproducible method for determining the photostability of sunscreen products. This method is based in part on the in vitro determination of the UVA protection factor as proposed by Colipa for the irradiation aspect, and on the spectroscopy of a sunscreen in dilute solution for the absorbance measurement aspect.
