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).
Resin Oils and Cyclic Dienes are considered
not to be skin or respiratory sensitisers. Specific data for three
streams, E000044012 [CAS 68478-10-4]; E000044146 [CAS 68478-10-4];
E000144700 [CAS 68516-20-1] indicated no skin sensitisation in guinea
pig assays. The components dicylcopentadiene, benzene, toluene, styrene,
xylenes and ethylbenzene are considered not to be skin sensitisers.
No data have been found concerning
respiratory sensitisation and there are no indications that components
within this stream are respiratory allergens.
sensitisation potential of E000044012 [CAS 68478-10-4] (Lyondell,
1990p), E000044146 [CAS 68478-10-4] (Lyondell, 1990q), and E000144700
[CAS 68516-20-1] (Lyondell, 1990r) was investigated in guinea pig
studies. For each substance dermal exposure to a 1:2 dilution of 0.5 mL
in mineral oil was used for each of 3 induction phases and a 1:4
dilution was used for challenge. Response grades, severity and incidence
were not greater than those at the control group site and all three
streams were considered not to be skin sensitisers.
components dicyclopentadiene, benzene, toluene, styrene, xylenes and
ethylbenzene are considered not to be skin sensitisers.
data identified was for benzene and xylenes:
(No classification): In a study using 25 male volunteers a maximisation
test with induction using 50% benzene and challenge with 20% benzene no
evidence of skin sensitisation was seen (Kligman, 1966).
(No classification): In a human maximization test (Kligman, 1966),
xylene was tested at 100% and subjects were challenged at 25%. No skin

are sufficient data on E000044012 [CAS 68478-10-4]; E000044146 [CAS
68478-10-4]; E000144700 [CAS 68516-20-1] and on component substances to
indicate that Resin Oils and Cyclic Dienes are not skin sensitisers. Although
there are no specific data on respiratory sensitisation of Resin Oils
and Cyclic Dienes streams or marker components there are no indications
that components within this stream are respiratory allergens. It
is proposed that no classification is warranted for these end-points
under Reg (EC) 1272/2008.
