Interaction between Octenidine-based Solution and Sodium Hypochlorite: A Mass Spectroscopy, Proton Nuclear Magnetic Resonance, and Scanning Electron Microscopy-based Observational Study
When Octenisept (OCT) was added to NaOCl, the solution turned milky white and precipitated. Mass spectroscopy and proton nuclear magnetic resonance analysis confirmed that the precipitate was phenoxyethanol. Phenoxyethanol is inherently present in OCT. The precipitate was sparsely distributed and only partly occluded the tubules.
