Description of key information

The melting point data for four streams were available. The melting point range was < -30 to 45°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
4.8 °C

Additional information

Melting point values for the streams in this category have been take from proprietary data, certificates of analysis and study reports and are considered reliable and suitable for use for this endpoint. CAS# 94733-07-0: 4°C (BASF, 2007); CAS# 68477-54-3: < -30°C (RÜTGERS 2010a, 2010b, 2010c, 2010d, 2010e, 2010f, 2010g, 2010h); CAS# 101316-62-5: < -30°C (RÜTGERS, 2010b); CAS# 68526-56-7: 35°C – 45°C (Dow Benelux 2010b).


The data will be read across to all category members.


The mean of the melting point values for the category is 4.8°C and this value has been used to complete the 'key value for chemical safety assessment'.
