Additional information

Examination of the chemical structure of DOWANOL™ TPnB-H Glycol Ether (tripropylene glycol n-butyl ether highers) shows that there is no functional group that could dissociate. The substance does not contain both, acidic or basic functional groups. DOWANOL™ TPnB-H Glycol Ether is not an ionisable organic substance and as non-ionisable ether-alcohol will tend not to dissociate in water under normal environmental conditions.
