EC number: 295-332-8 | CAS number: 91995-70-9 A complex combination of hydrocarbons obtained by solvent extraction of a vacuum-deasphalted residue. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly greater than C30. This stream contains more than 5 wt. % of 4- to 6-membered condensed ring aromatic hydrocarbons.

Additional information
In a key semi-static 96 -hour short-term rainbow trout (Oncorhynchus mykiss) limit test (OECD 203; KS=1), 10 fish/replicate were exposed to the Water Accommodated Fraction (WAF) of a residual aromatic extract (PSG 1857) at a nominal concentration of 1000 mg/L. The LL50 was >1000 mg/L and the NOEL was ≥ 1000 mg/L based on no observed mortality (BP Oil Europe, 1994a).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
