PBT assessment: overall result

Reference
Name:
Triethoxy(2,4,4-trimethylpentyl)silane
Type of composition:
boundary composition of the substance
State / form:
liquid
Reference substance:
Triethoxy(2,4,4-trimethylpentyl)silane
PBT status:
the substance is not PBT / vPvB
Justification:

The assessed substance, (2,4,4-trimethylpentyl)silanetriol is the silanol hydrolysis product of the submission substance.

Triethoxy(2,4,4-trimethylpentyl)silane hydrolyses moderately in contact with water to form (2,4,4-trimethylpentyl)silanetriol and ethanol.

 

The silanol hydrolysis product, (2,4,4-trimethylpentyl)silanetriol 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.
