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.

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.

To evaluate the comprehensive effects of shine and color intensity in hair, a hair color vibrance factor has been developed to enable new claims for hair dye formulas and after-dye treatments. Experimental results described here show how varying the ingredients in shine spray and hair dye formulas affect this factor and correlate with subjective panelist assessments.

Today, product formulation goes hand in hand with efficacy testing, but nearly 40 years ago, when Sergio Nacht, PhD, started out in the personal care industry, it was a different story. Throughout his decades in personal care, Nacht has developed methodologies that have allowed the personal care industry to establish efficacy of a product and convey this to the consumer. He has also been instrumental in the increased efficacy of personal care products through sustained release.

In some henna mixtures, para-phenylenediamine (PPD) has illegally been added and it is responsible for complications such as allergic contact dermatitis. While high-performance liquid chromatography has previously been used to detect PPD, a colorimetric method that is faster and portable, described here, has been developed. For product developers, this method can be used to evaluate henna plant extracts.

Genomics assists product developers in understanding the expression of specific genes and their relationship to particular skin attributes. This article reviews commonly used testing techniques, such as DNA microarray, RT-PCR, SAGE, northern blot and RNA sequencing, and describes their application in testing the effects of cosmetic ingredients and products on skin.
