P&G Presents 'Omics' Findings in Acne, Male Grooming, Dandruff and Anti-aging
During the World Congress of Dermatology, Procter & Gamble Beauty and Grooming is presenting new findings in acne, male grooming, dandruff and anti-aging based on a broader "omics"—i.e., genomics, proteomics and metabolomics, research tool.

Natural vs. Synthetic Antimicrobials and HDAC as an Indicator of Microflora Health
This article reviews the role of skin microflora in protecting skin, and assesses how the histone deacetylase (HDAC) enzyme is implicated. From this, HDAC expression is used as an indicator to compare the effects of traditional biocides and preservatives with natural antimicrobials on skin’s microbiome. Results suggest the latter effectively preserve products while maintaining a healthy microbiome.

New U.S. UV Filters and the Cosmetic Outlook in Canada for Sunscreens
Skin cancer is the most common cancer today, but only recently has industry pressure and political leadership compelled changes in the North American regulatory paradigm of sunscreen products. The passage of the Sunscreen Innovation Act in the United States and the suggestion to regulate sunscreens as cosmetics in Canada would give regulators the tools to reboot a stalled approval system.

Influence of pH on the Preservative Boosting Effect of Chelating Agents
A system based on phenoxyethanol and ethylhexylglycerin (euxyl® PE 9010) from Schülke & Mayr is described here to boost the efficacy of preservatives. To substantiate its efficacy, the effects of the system were checked at pH levels of both 7.0 and 5.0.

Testing Tactics: In Vitro Methods to Test Materials for UV Protective Capabilities
The methods described in this article highlight some of the markers that can be used to assess the UV protective effects of a test material. All of these markers represent either an index of UV-induced damage to the cell or the cell’s response to the damage.

In Vitro UV Testing—Robot vs. Human Spreading for Repeatable, Reproducible Results
Repeatability and reproducibility are crucial to validate any test method. In order to master these criteria, the authors developed an automated spreading device and compared it with human spreading. Application of the device in eight laboratories and using 36 sunscreens revealed great improvements via automated spreading, ensuring good intra- and inter-laboratory variability.
Microbiology
Determining Preservative Efficacy in W/O Formulas, Part II: Making Microbiological Safety Assessments
The relevance of microbiological tests for w/o formulas has been questioned, mandating a more holistic approach. This second article in a series examines the failure rate of PETs for w/o products but looks at why this does not mean insufficient stability.
