Conclusions:
Log Koc value -0.23 (TGD Kow prediction method) was obtained for the hydrolysis product using appropriate calculation methods. The result is considered to be reliable.

Description of key information

Low potential for adsorption.

For environmental exposure assessment, adsorption is predicted using the TGD (Technical Guidance Document) non-hydrophobics log Kow prediction method (EC, 2003c).

Log Koc = -0.23 for the silanol hydrolysis product.

The other hydrolysis product is ethanol with a Koc of 1.

Key value for chemical safety assessment

Additional information

Adsorption has been estimated based on log Kow using the TGD (Technical Guidance Document) non-hydrophobics equation. The log Koc of the silanol hydrolysis product was calculated to be -0.23.
