The Metastability and Nucleation Thresholds of Ibuprofen in Ethanol and Water-Ethanol Mixtures

Figure 2

SNT in ethanol at 10, 25, and 40°C. The curve represents the exponential of best fit (1) to all the data. In the graph the points represent the induction time range between the latest time before nucleation was definitely observed and the earliest time after nucleation definitely was observed. Nucleation must have occurred somewhere between these two times.
