Justification for data waiving:

Description of key information

Dissociation constant (triethoxysilane): not relevant
Dissociation constant (silanetriol): not relevant

Key value for chemical safety assessment

Additional information

The requirement to test the substance for dissociation constant is waived because in contact with water the substance rapidly hydrolyses to silanetriol and ethanol.

Triethoxysilane and its hydrolysis product are not expected to undergo significant dissociation within an environmentally-relevant range.
