In the present work, the antioxidant capacities of three essential oils derived from basil and thyme were evaluated using a photochemiluminescence (PCL)-based assay. In addition, since the base formulation can affect the antioxidant activity of oils contained therein, ingredient interactions within final formulations were investigated.

In the present article, the authors assess the skin irritation and sensitization potential of 1,3-propanediol (INCI: Propanediol). Results in animals and humans by acute or repeat exposure support a low potential of skin reactivity for the material. In addition, the skin reactivity potential in humans was found to be lower with 1,3-propanediol than 1,2-propanediol (INCI: Propylene Glycol).

While previous algorithms for predicting the skin absorption of permeants was based on in vitro data, the present article proposes a quantitative structure-activity relationship (QSAR) model based on in vivo human data. Here, a set of human in vivo data is described that provides entry into predicting the penetration of cosmetic ingredients.

Six questions from Michael Shermer’s Baloney Detection Kit have been discussed in this series. The results were not flattering for cosmetic science (read: cosmetic scientists) but cosmetic science did not score badly on all points. Questions seven and eight, described here, discriminate true science from borderland science and non-science or nonsense.

In this article, several methods to quantify the protein collected by tape stripping are described, including traditional gravimetric methods as well as novel colorimetric and visible spectroscopic techniques. Further, one colorimetric method is described to effectively determine the keratolytic efficacy of various materials in vivo, suggesting additional roles for this method.

Substantial evidence, which the FDA requires to support claims for drugs, is applicable to personal care, especially considering the pharmaceutical direction products have taken. The present article considers whether the industry is benefiting from marketing without assuming the responsibility for potential effects. In addition, it considers the limitations of in vitro and in vivo test models.
