log Koc [[3-(2,3-epoxypropoxy)propyl]trimethoxysilane]:
not relevant due to rapid hydrolysis of the substance in contact with
substance hydrolyses rapidly to substances which have low
log Kow values (<3) and thus has low potential for
adsorption, and the requirement for testing is waived.
For environmental exposure
assessment, adsorption is predicted for the silanol hydrolysis product
using the ‘non-hydrophobics’
log Kow-based prediction method for log Koc developed
by Sabljic and Güsten (1995) for the European Commission, and
recommended in EU Guidance.
The relevant equation is:
Log Koc = 0.52
log Kow + 1.02
Therefore, log Koc for
silanol hydrolysis product, [3-(2,3-epoxypropoxy)propyl]silanetriol
Sabljic A and Güsten H (1995).
