About
Dietmar Waidelich is a specialist in analytical chemistry and pharmaceutical formulation, with a focused expertise in the structural characterization of complex, non-ionic emulsifiers. His most significant contributions center on the detailed analysis of Cremophor® EL (CrEL), a critical excipient used in drug delivery systems. Through innovative applications of hyphenated capillary electrophoresis and delayed extraction-matrix assisted laser desorption/ionization-time of flight-mass spectrometry (DE-MALDI-TOF-MS), Waidelich achieved the first separation and structural elucidation of CrEL's heterogeneous polyethoxylated components. His work identified and characterized two novel components: polyoxyethylene-Δ9,11-didehydrostearate and glycerol-polyoxyethylene-Δ9,11-didehydrostearate. These findings, published in 2002, resolved long-standing ambiguities about the emulsifier's composition, providing a foundational understanding for its safe and effective use in pharmaceuticals. While his citation counts (18 and 9) reflect a niche but highly specialized impact, his work is a cornerstone for researchers studying excipient chemistry and formulation science, demonstrating how advanced analytical techniques can unravel the complexity of industrial-grade materials.
