Executive summary:

Vapour pressure 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 <0.01 kPa (<10 Pa) at 25ºC (298.15 K),

Description of key information

Vapour pressure of hexylene glycol  is reported to be <0.01 kPa (<10 Pa) at 25ºC (298.15 K), and 0.05 mmHg (6.66 Pa) at 20ºC (293.15 K).

Key value for chemical safety assessment

Vapour pressure:
6.66 Pa
at the temperature of:
293.15 K

Additional information

Information regarding vapour pressure of hexylene glycol was sourced from various handbooks or review articles including ACGIH (2001), CRC Handbook of Chemistry and Physics (81st Ed.), Dangerous Properties of Industrial Materials (7th Ed.), and Patty's Industrial Hygiene and Toxicology (4th Ed.). However, Patty’s Industrial Hygiene and Toxicology and ACGIH cite secondary sources that are not peer-reviewed, and thus, are not considered valid. Instead, vapour pressure 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 <0.01 kPa (<10 Pa) at 25ºC (298.15 K), and 0.05 mmHg (6.66 Pa) at 20ºC (293.15 K).
