Ozokerite, a natural mixture of long-chain paraffins, is found at Ein-Humar (Jordan) on the eastern escarpment of the Dead Sea. The Ein-Humar ozokerite is mainly composed of saturated n-paraffins from C30 to presumably well into the C50′s with a maximum at C38. IR, NMR and chromatographic data ...detailed
Raman spectra were obtained from the natural crystalline (evenkite) and amorphous (ozokerite and hatchetin) hydrocarbons, originating from volcanic and sedimentary rocks from several sites (Merník, Evenki, Zastávka). Raman spectra of all materials investigated confirm their exclusively aliphat...detailed
Combined chronic toxicity and carcinogenicity studies of ozokerite (OZK), a natural wax substance used as a food additive for a gum base, were performed in male and female F344 rats. Dietary concentrations of 0%, 0.05%, 0.1% and 0.2% OZK were applied in a 52-week chronic toxicity study and 0%, 0...detailed
The aim of the study was to analyse the microbiological and biochemical activity of a reclaimed landfill produced during extraction and processing ozokerite and sown with Trifolium hybridum and Dactylis glomerata. The analyses were carried out in the third year after application of two doses of ...detailed
