Description of key information

Dibutylpolyglycol: -44°C (company brochure)
Dibutyldiglycol: -60°C (handbook)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-44 °C

Additional information

A company brochure reports a melting point for dibutylpolyglycol of -44°C without providing experimental details or proof of data.

Secondary peer reviewed article reporting a melting point for Dibutyldiglycol, one of the constituents of the mixture of homologues, of -60°C without providing information on original source or experimental details. Both available data consistently documenting melting far below -20°C.

In accordance with column 2 (Specific rules for adaptation from column 1) of REGULATION (EC) No 1907/2006 (REACH), Annex VII, information requirement 7.2, this study does not need to be conducted below a lower limit of - 20 °C.
