REACH and In Vitro Alternatives: Phototoxicity Testing

This is the third column in a continuing discussion regarding the new REACH regulations and their impact on chemical testing. The first appeared in December 2007 and discussed dermal corrosive potential testing; the second, in February 2008, covered dermal irritancy potential testing.

ATP Bioluminescence: Detecting Microbial Contamination in Dentifrices

In tests on eight dentifrice formulations, a bioluminescence system based on adenosine triphosphate (ATP) detected tested microorganisms qualitatively within 24-27 hours, compared to 5-7 days required for quantitative detection by standard methods.

Detecting Water Content in Deep Eutectic Solvents

Research appearing in the Journal of Molecular Liquids explores the use of ATR-IR spectroscopy to estimate the water content in natural deep eutectic solvents.

Inducing Hormesis for a Lipofilling-like Action

The present article discusses a new approach to mimic lipofilling—the activation of hormesis, which is accomplished by the described encapsulated active designed to induce a transitory stress and initiate an overcompensation to reestablish homeostasis. This leads to the compensation of age-induced lipoatrophy and correction of wrinkles and folds, for a younger-looking appearance.

The Safety Factor in Preservative Efficacy Testing

The authors explain how preservative efficacy testing is done to determine whether a formula is adequately preserved. Product contamination problems are frequently caused by inadequate preservation.

Truth in Exposure: Disparity Dictates Product Safety

How often do you relax your hair? or color it? Clearly, some consumers are exposed to given products more than others based on preferences or practices. A new study points to this fact as a crucial component for regulators to consider when determining ingredient safety.

Lightening Skin Through a Melanogenesis-interrupting Peptide

Cutaneous pigmentation is determined by melanogenesis, the transfer of melanosomes to keratinocytes, and the distribution of melanin to skin, among other processes. Interrupting these would limit skin pigmentation to achieve a better skin lightening effect. Here, the authors review the biological mechanisms of melanin production, then test a peptide designed to act on them for a lightening effect.

Genetic Test for Alopecia Approved in Europe

The HairDX Genetic Test for Hair Loss, a genetic baldness test manufactured by HairDX LLC, is now available as a CE Marked product under the European In Vitro Diagnostic Directive.

Detecting Coral Stress in Response to Sunscreens

Metabolomics is at the heart of recent work published in Nature Scientific Reports, wherein an increase in a known steroid in coral was noted in the presence of three common sunscreen ingredients.

Predicting the Percutaneous Penetration of Cosmetic Ingredients

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.

CeeTox Expands In Vitro Capabilities with Acquisition

CeeTox has acquired assets of ADMETRx Inc. that allow it to expand its range of in vitro service offerings. Specifically, the acquired assets allow CeeTox to increase its existing Absorption, Distribution, Metabolism, Excretion (ADME) capabilities.

In Vitro Model for Decontamination of Human Skin

The present study utilized an in vitro model to compare the decontamination capacity of three model decontaminant solutions: tap water, isotonic saline and hypertonic saline. Human cadaver skin samples were dosed with radio-labeled [14C]-formaldehyde and the surface skin of each sample was washed after each exposure with one of the three model decontaminant solutions.
