PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Trimethoxy(2,4,4-trimethylpentyl)silane
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- Trimethoxy(2,4,4-trimethylpentyl)silane
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Methanol is the alcohol hydrolysis product of the registered substance trimethoxy(2,4,4-trimethylpentyl)silane (CAS 34396-03-7).
Methanol is readily biodegradable and therefore does not meet the screening criteria for persistence (not P/vP).
Methanol has a log Kow of -0.82 to -0.64 and therefore does not meet the screening criteria for bioaccumulation (not B/vB).
Methanol has a low environmental hazard profile and is not classified as carcinogenic, mutagenic, toxic for reproduction, chronic toxicity or specific organ toxicity and therefore does not meet the criteria for toxicity (not T).
Based on ECHA guidance R.11, methanol does not meet the overall criteria for PBT or vPvB.
