Reference substance:
3-(Trimethoxysilyl)propyl isocyanate
PBT status:
the substance is not PBT / vPvB

The assessed substance, methanol is the non-silanol hydrolysis product of the submission substance. The submission substance hydrolyses very rapidly in contact with water to form 3-aminopropylsilanetriol and methanol.

Methanol is readily biodegradable, hence does not persist in the environment; therefore, methanol should not be concluded as PBT or vPvB.
