A cosmetic ingredient innovation for the stabilization and delivery of volatile fluoroether with cosmetic...

Initially this work attempts to support, evaluate and identify the stabilization and release mechanism of volatile fluoroether (Cosmetic Fluid CF-61) in a self-assembling nanostructure in an external water phase (Phoenomulse CE-1) through evaporation rate analysis. The release mechanism is hypothesized to be a result of a dehydration process, a decrease in water efficiency due to evaporation of external water at the liquid-air interface, which results in destabilization of the nanostructure. This work further attempts to quantify the release mechanism of the same volatile fluoroether (Cosmetic Fluid CF-61) from the nanostructure in cosmetic formulations through a newly developed in vitro test method which measures initial foam generation rate. Finally, this work demonstrates the application of these newly developed test methods as a useful tool for product development, formulation navigation, and performance optimization.
