Description of key information
The test item was determined to decompose woithout melting from approximately 191°C (464 K). As the test item decomposed, no value for melting point could be determined.
Key value for chemical safety assessment
Additional information
A melting/ freezing point determination was conducted as part of a package of physicochemical testing on Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts (Envigo Research Limited, 2018, Study GT32WD). The study was conducted in compliance with GLP and the freezing point determination was performed according to Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995 test guidelines.
The C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts was determined to decompose from approximately 191 °C (464 K).
As the test item decomposed, no value for melting point could be determined.
