Type of composition:
boundary composition of the substance
State / form:
Reference substance:
(3-Chloropropyl)triethoxysilane, CAS 5089-70-3; EC No. 225-805-6
PBT status:
the substance is not PBT / vPvB

The assessed substance, ethanol, is the non-silanol hydrolysis product of the submission substance.

The submission substance hydrolyses moderately rapidly in contact with water to form (3-chloropropyl)silanetriol and ethanol.

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