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.

Alcohol is a complex regulatory issue that confuses many chemists and marketers, as well as regulatory experts, as to the permitted grades, required uses and proper labeling—which vary by country. This confusion can lead to use of the wrong denaturants and levels, custom holds on imports and exports, and consumer misuse. The regulation of alcohol rarely changes but these problems remain.

From Elastin to Elastic Fibers, Part II: The Clinical Effects of a Natural Dipeptide on the Biological Cascade
By: Philippe Mondon, Sebastian Fache and Emmanuel …
The peptide N-Acetyl-Tyr-Arg-Hexadecylester (NATAH), found in Part I to stimulate the production of elastic fibers in vitro, was next tested in vivo for its capacity to improve skin elasticity parameters, using various biophysical and imaging techniques. Significant differences in facial ptosis and extensibility were observed in the 56-day, vehicle-controlled clinical study described here.

Saccharide isomerate, designed to closely resemble a carbohydrate complex found in human stratum corneum, is shown here to provide up to 72 hr of deep hydration to skin and, for the first time, rinse-off soothing to the scalp. Its unique binding mechanism to skin and scalp create new opportunities for leave-on and rinse-off products.
