PBT assessment: overall result

Reference
Name:
Methylsilanetriyl triacetate
Type of composition:
boundary composition of the substance
State / form:
solid: particulate/powder
Reference substance:
Methylsilanetriyl triacetate
PBT status:
the substance is not PBT / vPvB
Justification:

The assessed substance is the hydrolysis product of the submission substance. The submission substance hydrolyses very rapidly in contact with water to form methylsilanetriol and acetic acid.

The silanol hydrolysis product, methylsilanetriol may persist in the environment but does not meet the criteria for B or T, and therefore the hydrolysis product should not be concluded as PBT or vPvB.
