[podcast] CAS9 and CRISPR Technology: Implications for Cosmetics?
"CRISPR, in my mind, is like a molecular GPS. . .People just type in some short array sequence, essentially an address, to find the target. Upon binding to the target, a pair of molecular scissors cuts the DNA and performs a repair to modify the DNA sequence."

Tools to Predict, Assess and Standardize Successful Color Cosmetics
Cosmetic companies have borrowed quality control methods from other industries that have product attributes such as color, gloss and texture down to a science. Specialized in such areas, X-Rite has developed tools to enable cosmetic companies to predict future color trends as well as set standards by which future cosmetics will be benchmarked.

ICCVAM Recommends Ocular Safety Tests for Cosmetics and Other Products
Four test method evaluation reports are now available from ICCVAM that provide recommendations for performing eye safety testing more humanely, and for developing and using non-animal test methods and strategies. Among these reports, ICVAAM has recommended that a cytosensor microphysiometer (CM) test method may be used to screen surfactant-containing formulations such as personal care products for the ability to cause permanent or severe eye injuries.

A Dermatological View: Antioxidant Inhibits UV Erythema In Vivo in Humans
Described here was an in vivo model to determine antioxidative capacity of a topical skin care emulsion versus the emulsion’s vehicle on human skin that was exposed to UVR. Results suggest the test emulsion and its vehicle control inhibited the induction of erythema and reduced inflammation caused by the UV exposure.

Adjusting Substrate/Product Interfacial Properties to Improve In vivo/In vitro SPF Correlation
This work evaluates the impact of a plasma treatment on test substrates to modify their surface energy, to more closely correlate in vitro SPF measurements with in vivo measurements—without chemically altering the test products. The authors chose the level of plasma modification to use on a substrate based on in vivo values; they explain how to choose it regarding specific formulas in a further paper.
