EC number: 270-790-1
CAS number: 68478-10-4
A complex combination of hydrocarbons obtained by the distillation of debenzenized light steam-cracked naphtha. It consists predominantly of cyclic olefinic and aromatic hydrocarbons having carbon numbers predominantly in the range of C8 through C16 and boiling in the range of approximately 130°C to 300°C (226°F to 572°F).
Short term toxicity to fish data are
available for 2 streams within this Category. The 96 hour LC50s
ranged from 0.58 - 13.5 mg/L. The 96 hour LL50 range based on
two studies was 0.73 - 6.3 mg/L.
No 68478-10-4 (ACC, 2004c): This is a GLP compliant, guideline study.
After Oncorhynchus mykiss were exposed to WAFs prepared from
Dicyclopentadiene/Codimer Concentrate for 96 hours, the LL50 was
0.73 mg/L and the LC50 was 0.58 mg/L.
No 68477-54-3 (ACC, 2004d): This is a GLP compliant, guideline study.
The LC50 of Low DCPD Resin Oil (MRD-03-630) was determined to
be 6.1 mg/L and the LL50 was 6.3 mg/L after 96 hours of
No 68477-54-3 (Sabic, 1989b): This is a GLP compliant, guideline study
and is considered adequate for assessment. The 48 and 96 hour LC50 toxicity
of C9-Resin feed to Brachydanio rerio was determined as 13.5
mg/L. After 96 hours of exposure, all animals were alive at 10 mg/L but
total mortality was observed at 18 mg/L. After 96 hours of exposure, the
NOEC was determined as 5.6 mg/L (mortality and condition) based on
authors report results based on nominal loading rates (WAF) and mean
measured concentrations. As the test substance is a hydrocarbon stream
with various components reporting a measured concentration could be
misleading as the measured concentration does not relate to a
concentration of the raw stream. Instead, we have used the results
reported as WAF, which better represent the potential toxicity of the
