The accurate quantification of polysorbate 20 in drug formulations is of critical importance in the pharmaceutical industry. In this study, the behaviour of PS20 with different buffers and a drug substance using mid-infrared spectroscopy was investigated. Multiple methods have been developed in recent years to analyse polysorbate components in drug products. Infrared spectroscopy (IR) has the potential to become one of the most important analytical technique available in industry nowadays. IR is a non-invasive and non-destructive technique that requires minimal sample preparation and provides a realtime response, provides qualitative and quantitative information in a fast, cost-effective way. In this study, the suitability of mid-infrared spectroscopy for quantifying PS20 in formulated drug substance and placebo formulations was evaluated. The analysis was performed using two characteristic bands of PS20, the stretching C=O region between 1720 - 1770 cm-1 and the C-O group from the ethyl moiety between 1050 - 1200 cm-1. The results of this study provide important insights into the use of IR as a method for quantifying PS20 in drug substance and the ability of this technique to detect changes accurately and sensitively in different sample matrices. IR was applied to determine the correlation between the absorption values of the C=O and the C-O-C band of PS20 and the nominal PS20 content. The study showed that the method is capable of quantifying PS20 as low as 0.04 g/L in the placebo buffer and 0.12g/L in drug substance with high accuracy, demonstrating the high resolution and reproducibility of the MIRA method. The percentage accuracy in quantifying PS20 using this method was found to be ≥ 90%, which demonstrate the potential of this method as a useful tool for the pharmaceutical industry, given its ability to accurately quantify PS20 in drug substances.
