PBT assessment: overall result

BTMAOH - pure substance (theoretical composition)
Type of composition:
legal entity composition of the substance
State / form:
solid: bulk
Related composition:
BTMAOH - 40% solution in methanol (as manufactured and as tested in substance identification analyses)
Reference substance:
BTMAOH - pure substance (theoretical composition)
PBT status:
the substance is not PBT / vPvB

The substance is considered not PBT / vPvB:

- Not P/vP, since it is readily biodegradable;

- Not B/vB, since log pow < 4.5;

- Although no classification for carcinogenicity, mutagenicity, reproduction/developmental toxicity or specific target organ toxicity is applicable and the acute L(E)C50 values are > 0.1 mg/L, a definitive classification as not T is not possible, due to the lack of chronic environmental toxicity studies.

However, since the substance is not P/vP and not B/vB, it can be concluded that the substance is not PBT/vPvB.
