Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Derived using calculation method software. Current versions of EPIWIN, developed by Syracuse Research Corporation, have not been validated for estimating endpoints for chemicals that contain metals in their molecular structure; therefore, the estimated values derived from the EPIWIN models should be used with caution.
Principles of method if other than guideline:
Method: other: (calculated) EPIWIN v4.0
0 atm m³/mol
Calculation determined Henry's Law Constant. It was determined to be 4.59E-6 atm m3/mol.

Description of key information

A Henry's Law constant of 31820 4.598E-06 atm m3/mol was determined using valid calculation software.

Key value for chemical safety assessment

Additional information

A Henry's Law constant of 4.598E-06 atm m3/mol was determined using valid calculation software. This predicts that MMT(2-EHMA) will volatilise only minimally from surface water; half-lives from a model river or lake are 350 hours and 168.6 days, respectively.
