 \section{Results and discussion}
 
+\subsection {Extraction and Solvation of ASA}
+
+The synthesis began with the mechanical breakdown of commercial aspirin tablets (500~mg ASA/tablet) using a mortar and pestle. The resulting powder was digested in an excess of methanol for one hour with constant stirring.  \\
+
+The heterogeneous mixture was subsequently clarified via filtration through a cellulose-based filter. This step effectively isolated the soluble ASA and miscible plasticizers from the insoluble structural excipients and pigments (Table~\ref{tbl:solubility}).
