EC number: 310-013-6
CAS number: 102110-15-6
A complex combination of hydrocarbons obtained by distillation of the products from a steam-cracking process. It consists predominantly of hydrocarbons having carbon numbers of C5 and dicyclopentadiene and boiling in the range of approximately 30°C to 170°C (86°F to 338°F).
Three biodegradation studies were available for two streams within this Category. All three studies showed that the streams could not be considered readily
Three proprietary studies are
available for this Category (ACC, 2007a; 2004a,b).
One of the studies is performed with
DCPD/Codimer Concentrate (CAS No. 68478-10-4). This study is GLP
compliant and followed OECD guideline 301F and therefore the study is
considered adequate for assessment. DCPD/Codimer Concentrate cannot be
considered readily biodegradable as there was no measurable
biodegradation observed over a 28 day testing period.
Two studies are available for the
stream with CAS No. 68477-54-3. Both studies are GLP compliant studies
following OECD guideline 301F and are considered adequate for
assessment. The average percent biodegradation of the test substance in
one of the studies was determined to be 43.87% by day 56. The toxicity
control exceeded 25% therefore the test substance cannot be considered
inhibitory. The average percent biodegradation of the test substance in
the other study was determined to be 6.48% on day 41.
