Description of key information

The melting point (pour point) of the streams in this category is in the range < -100˚C to < -30˚C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-30 °C

Additional information

A proprietary study was available from GKA Competence Centre Analytics (2008) for stream 68477-39 -4 (<-100˚C). This study was conducted in accordance with a standard guideline and are considered reliable for assessment. The data from this study will be read across to other members of the category.

RÜTGERS Germany GmbH, Analytisches Zentrallabor (AZL) (2010) provided data for the stream 64742-94-5 (pour point <-30˚C) via a signed Certificate of Analysis. The data provided details on the method used and was considered adequate for assessment.

The 'key value for chemical safety assessment' has been completed using a melting point value of -30°C as this represents the <-30°C result, which covers the other results for this category as well.
