Naftalan oil consists of naphthenic hydrocarbons and is an easily accessible substance, obtained by vacuum distillation and hydrocracking from native Naftalan. Its composition contains 99.8% naphthenic hydrocarbons, which have desensitizing, anti-inflammatory, analgesic, wound-healing, antispasmodic, resorptive, antipruritic, and antibacterial effects.
Dewaxed naftalan oil
Dewaxed Naftalan is an easily accessible substance, obtained by vacuum distillation and hydrocracking from native Naftalan oil.
Refined naftalan oil
Refined Naftalan oil must comply with the pharmacopoeial monograph FS 42-1957-82. It is a thick, syrup-like liquid of black color with a greenish fluorescence, having a characteristic odor and a weakly acidic reaction. It does not mix with water. It mixes in all proportions with glycerin, ceresin, oils, fats, paraffin, and wax (SP-X, p. 75). Density is 0.918-0.958 (SP-X, p. 772). The initial boiling temperature must be not lower than 160 degrees Celsius (SP-X, p. 769). Water content is not more than 0.5% (SP-X, p. 772).
Native naftalan oil
Naftalan is a thick liquid of black-brown or brown color, which in appearance differs little from industrial types of oil. A distinctive feature of naftalan is its high specific gravity (from 0.927 to 0.970), which is обусловлено, firstly, by the insignificant content of light fractions (the level of which in other oils reaches up to 50%), the absence of low-boiling and solid hydrocarbons of the paraffin series, and secondly, by the significant content of naphthenic and aromatic hydrocarbons and resins.
