Proposed Method to Evaluate the Microbiological Stability of Cosmetics During Use
The authors propose an approach to assess the microbial stability of a product during use, referred to as the Microbiological Use Test (MUT), and apply this analysis in case studies to predict the microbiological risk of commercial products. The described test has been used successfully in the development of cosmetics.

Soothing Moves:
Cannabis Sativa
Cell Culture Alleviates Inflammation
The field cultivation of hemp is tasked by today’s large-scale demand. Here, a
Cannabis sativa
cell culture extract is proposed as a sustainable alternative. After initial characterization, the extract was tested as described here for efficacy against inflammatory markers for skin-soothing activities.

Opportunity in Diversity: Formulating for the Multiethnic Market
The expanding multicultural beauty market provides opportunity to formulate products specifically to the needs of ethnic skin types. Pigmentation is not the only difference between black and Caucasian skin, the skin barrier and other factors come into play.
Sensory
Testing Tactics in Skin: Keratinocytes as Sensory Nociceptors
Humans value senses of touch and warmth while enjoying their surroundings but pain and itch are also part of this experience. The present column explores Transient Receptor Proteins (TRPs), how they sense pain and itch, and their potential application in skin care and anti-aging products.

Free Formaldehyde Preservative Stability in Personal Care: Part II—Formulations
As scrutiny of formaldehyde-donor (FD) and other preservative technologies has increased in recent years, additional assurances of the relative safety and benefits of FD technologies are required. This two-part article examines the effects of temperature and pH on free-formaldehyde levels (as detected by C-13 NMR), first in water, then in personal care formulations.
