The next step to Stability Comparison:
The Turbiscan® device is well-known for providing substantial information on the
stability and dispersibility of any formulation. Such data is obtained by
monitoring the evolution of the backscattered and/or transmitted light intensities
over time. However, in some cases it may be difficult to objectively analyze the
data without an expert eye, for example in case of simultaneous destabilization
phenomena (e.g. sedimentation and aggregation). Formulaction has developed
a simple and robust criterium called the Turbiscan Stability Index (TSI) to rapidly
compare and characterize stability of formulations. This application note
describes how the TSI is calculated and provides with examples of use.
