EC number: 269-781-5 | CAS number: 68333-25-5 A complex combination of hydrocarbons obtained by treating light catalytic cracked distillates with hydrogen to convert organic sulfur to hydrogen sulfide which is removed. It consists of hydrocarbons having carbon numbers predominantly in the range of C9 through C25 and boiling in the range of approximately 150°C to 400°C (302°F to 752°F). It contains a relatively large proportion of bicyclic aromatic hydrocarbons.

Additional information
Conclusion on classification
Aquatic toxicity data for fish,Daphniaand algae are in range <1 mg/Lfor some Cracked Gas Oils. Some Cracked Gas Oils may not meet criteria for ready degradability and components have log Kow values in the range 3.9 to greater than 6. Therefore Cracked Gas oils are classified as Aquatic Acute Toxicity 1 (H400: Very toxic to aquatic life) and Aquatic Chronic Toxicity 1 (H410: Very toxic to aquatic life with long lasting effects).
