New Perspectives in Emulsion Formation
By: Katie Anderson (Schaefer), Cosmetics & Toiletr…
Previously, the theory explaining emulsion behavior was based on the equilibrium contact angle of the particle at the interface; however, Vinothan N. Manoharan, PhD, and his team at Harvard believe the time allowed for the system to reach equilibrium and the force pushing the particle to the interface are equally as important.

Elicitation of Rice Tissue Culture to Maximize Skin Epigenetic Modulation
Meristem cells of Himalayan red rice were cultured and elicited to produce secondary metabolites. Through an in vitro assay, rejuvenation was shown at the epigenetic level of treated cells. An increased expression of dermatopontin in keratinocytes, besides being a novel finding, implies that ReGeniStem™ Red Rice may be able to firm the skin and improve the skin barrier function.
