Description of key information

Melting point of hexylene glycol  is reported to be -50°C (corresponding to 223.15 K).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
223.15 K

Additional information

Information regarding melting/freezing point of hexylene glycol was sourced from various handbooks or review articles including CRC Handbook of Chemistry and Physics (81st Ed.), Dangerous Properties of Industrial Materials (7thEd.), and Patty's Industrial Hygiene and Toxicology (4th Ed.). However, Patty’s Industrial Hygiene and Toxicology cites secondary sources that are not peer-reviewed, and thus, is not considered valid. Instead, melting point of hexylene glycol was sourced from CRC Handbook of Chemistry and Physics and Dangerous Properties of Industrial Materials, which used primary and peer-reviewed sources, and is reported to be -50°C (corresponding to 223.15 K).
