Administrative data
PBT assessment: overall result
- Name:
- N,N-Dihydroxyethyl-p-toluidine
- Type of composition:
- boundary composition of the substance
- State / form:
- solid: bulk
- Reference substance:
- N,N-Dihydroxyethyl-p-toluidine
- Name:
- N,N-Dihydroxyethyl-p-toluidine
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: bulk
- Reference substance:
- N,N-Dihydroxyethyl-p-toluidine
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT assessment of N,N-Dioxethyl-p-toluidin (CAS 3077-12-1) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).
Persistence
The substance is not readily biodegradable (1.5% in 28 d, OECD 301 B). Therefore, it qualifies as potentially P/vP.
Bioaccumulation
The substance has a log Kow of < 3.0, which is below the trigger value of 4.5 for bioaccumulative substances. Therefore, it does not meet the screening criterion for bioaccumulation and is therefore not B/vB.
Toxicity
The substance is not classified as CMR or STOT RE category 1/2 according to the consolidated version of Regulation (EC) No 1272/2008 (dated 01.03.2018) and further amendments (ATPs). Moreover, no chronic effects were recorded in the available ecotoxicological studies (OECD 201). Therefore, the substance does not meet the T-criterion.
In conclusion, the substance is not PBT / vPvB.
