Multiscale Physicochemical Analysis of Defect Formation in Paraffin-Based Organic Systems: DSC Evaluation of Processing and Storage Conditions

This study presents a multiscale physicochemical analysis of defect formation mechanisms in paraffin-based organic systems subjected to different thermal histories. Paraffin materials, structurally analogous to biomimetic lipid matrices used in biomedical applications, were examined using differential scanning calorimetry (DSC) to determine the influence of processing conditions and storage temperature on phase stability and microstructural organization. Samples produced on two technological lines—a low-temperature process (D1) and a high-temperature process (D2)—were analyzed immediately after production and after storage at 15 °C, 25 °C, and 40 °C. DSC measurements revealed modifications in melting and crystallization profiles, together with additional thermal effects that suggest possible phase reorganization and changes in crystallization behavior under selected storage conditions. These effects were particularly visible for samples stored at 15 °C. The results provide an integrated thermal and spectroscopic interpretation of phase behavior in paraffin-based organic materials.
