Analysis of the properties of PCLs along with the times 0, 15, 30, 60, 90, and 120 days for size (nm, A, and B); zeta potential (mV, C). The encapsulation efficiency (%, D) was expressed as the mean and standard deviation of the five batches of PCL formulation. E Distribution as a function of intensity (DLS) over 120 days; F Comparison between the diameter distribution as a function of concentration (NTA) and intensity (DLS). The respective values were expressed as mean and standard deviation (n = 3) for five identical PCL formulation lots loaded with 5% IR3535 and 2% geraniol (GRL)
