| Abstract: | Ozonized oils have interesting applications in the cosmetic industry and several patents on enriched products were developed in the last years. Ozonides are known for their high reactivity and stability data are required for enriched cosmetic products during storage. In this paper a dedicated determination of Peroxide Value (PV) was performed on ozonized sunflower oil (Neozone 4000) and on some enriched cosmetics, in order to control their stability during storage. The optimal conditions of the PV method were determined, following the decomposition reaction of ozonides with KI utilizing 1H-NMR and GC/MS techniques. |
