Conclusions:

The substance Cyclacet has a self-ignition temperature of below 400°C according to EU Method A.15 in compliance with GLP.

Description of key information

Cyclacet Dihydro has an autoflammability of > 400oC.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

400 °C

Additional information

In accordance with Column 2 preliminary information presents an autoflammability value of > 400oC. This information is retrieved from a very similar substance Cyclacet for which an autoflammability of > 400oC has been derived.

Cyclacet Dihydro and Cyclacet have identical structural features consisting of a tricyclodecan-e/yl fused ring structure and an acetic ester attached at the bridged hexyl ring. The difference is that Cyclacet Dihydro (as presented in the name) does not have a double bond in the pentyl -ring which Cyclacet has. This absence of double bond is not expected to have any difference in autoflammability potential and therefore the read across is justified.
