Detecting Estrogenic Endocrine Disruptors in Personal Care Products and Supplements
By: John D. Gordon, PhD, and Andrew Chu Research T…
Endocrine disruptor chemicals (EDCs) are a class of chemicals that has raised alarm for being linked to a wide variety of detrimental effects on human and wildlife populations, e.g., cancers, precocious puberty and obesity. Thus, there is a need to test personal care products and supplements for EDCs, which can be accomplished using the validated bioassay described here.

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.
