Conclusions:

In a valid guideline study Isobornyl acrylate had no melting point above -50 °C at 1013 hPa measured by DSC according to European Commission Regulation (EC) No. 440/2008, A.1. as well as OECD 102 (1995), GLP. (ARTF, 2021)
 
There was no exact melting point detected for IBOA.
Decomposition started at approx. 140 °C.

Description of key information

Isobornyl acrylate had no melting point above -50 °C at 1013 hPa measured by DSC according to European Commission Regulation (EC) No. 440/2008, A.1. as well as

OECD 102 (1995), GLP. (ARTF, 2021)

 

There was no exact melting point detected for IBOA.

  

The EPI Suite calculation predicted melting point is not a realistic value as IBOA would be solid at room temperature, which it is not.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:

-50 °C
