title: Rheology of two commercially available cosmetic oil in water emulsions.
abstract: Rheological experiments were performed on two cosmetic O/W creams, CG Clarifying and CG Clean, before and after treatment (temperature, tumbling, centrifugation). Viscometry experiments were conducted in a shear range of 0.48-58 s ;-1. Strain sweeps were carried out at 0.1, 1, 5 and 10 Hz. Finally, frequency sweeps were performed in the linear viscoelastic region between 0.1 and 5 Hz. The characteristics of a ;good' O/W cream were found to be shear thinning behaviour, low yield stress, and predominately elastic behaviour.
