Reference
Name:
2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl]-4-methylphenyl acrylate
Type of composition:
legal entity composition of the substance
State / form:
solid: bulk
Related composition:
2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl]-4-methylphenyl acrylate
Reference substance:
2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl]-4-methylphenyl acrylate
PBT status:
the substance is not PBT / vPvB
Justification:

The PBT Assessment for 2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl]-4-methylphenyl acrylate (CAS 61167-58-6) 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

2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl]-4-methylphenyl acrylate (CAS 61167-58-6) is not readily biodegradable (0% after 14 days). Thus, the substance is considered to be potentially vP/P.

Bioaccumulation

An experimental study performed according to a guideline similar to OECD 305C resulted in BCF values of ≥ 6.1 and < 14 showing a low potential for bioaccumulation. This result is further supported by several QSAR models. All BCF values are clearly below the trigger value for B, which is a BCF of 2000. Thus, 2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl]-4-methylphenyl acrylate is not considered to be B/vB.

Toxicity

2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl]-4-methylphenyl acrylate (CAS 61167-58-6) is not classified for human health hazards. Moreover, no toxicity was recorded in ecotoxicological studies. Therefore, the substance does not meet the T criterion.

Conclusion

In conclusion, 2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenyl]methyl]-4-methylphenyl acrylate (CAS 61167-58-6) is not considered to be PBT or vPvB.
