Description of key information

Compositional complexity of the substance makes experimental determination of a single dissociation value impossible. A combination of QSAR calculated and other reported values for substance constituents has therefore been used to determine a dissociation constant range applicable to the whole substance. 

Key value for chemical safety assessment

pKa at 20°C:

Additional information

Based on QSAR modelling of the constituents of the substance, the pKa range of 14.7-15.8 is considered applicable for Glycol Ether Heavies.
