Residual oils (petroleum), oxidized A complex combination of organic compounds, predominantly high molecular weight carboxylic acids, obtained by the air oxidation of a solvent deasphalted residual oil.

Residual oils (petroleum), hydrotreated solvent dewaxed Baseoil - unspecified 649-491-00-9

Residual oils (petroleum) Heavy Fuel oil [A complex combination of hydrocarbons, sulfur compounds and metal-containing organic compounds obtained as the residue from refinery fractionation cracking processes. It produces a finished oil with a viscosity above 2cSt. at 100 °C.] A complex combination of hydrocarbons, sulfur compounds and metal-containing organic compounds obtained as the residue from refinery fractionation cracking processes. It produces a finished oil with a viscosity above 2cSt. at 100°C. 649-045-00-3

Residual oils (petroleum), solvent deasphalted Baseoil - unspecified [A complex combination of hydrocarbons obtained as the solvent soluble fraction from C 3 -C 4 solvent deasphalting of a residuum. It consists of hydrocarbons having carbon numbers predominantly higher than C 25 and boiling above approximately 400 °C (752 °F).] A complex combination of hydrocarbons obtained as the solvent soluble fraction from C3 - C4 solvent deasphalting of a residuum. It consists of hydrocarbons having carbon numbers predominantly higher than C25 and boiling above approximately 400°C (752°F). 649-456-00-8
