EC number: 297-025-4
CAS number: 93281-13-1
The substance is not readily biodegradable
in standard tests for biodegradability. Furthermore, abiotic degradation
by hydrolysis is considered as negligible, since the substance resulted
to be hydrolytically stable.
Based on the available information, the
substance can be considered as potentially P or vP.
Many substances with a molecular mass
greater than 700 are not readily taken up by fish, because of possible
steric hindrance at passage of gill membranes or cell membranes of
respiratory organs. Direct Black 168 has a molecular weight higher than
800 g/mol and is characterized by a negative log Kow.
Thus, B-criterion is not met.
Aquatic long-term toxicity data is not
available, therefore the aquatic toxicity assessment and classification
are based mainly on the short-term toxicity data. Short-term toxicity
studies show that the substance should be considered as harmful to
aquatic life with long lasting effects for aquatic life, according to
the criteria of CLP Regulation (EC) No 1272/2008.
The substance is not classified as
carcinogenic, germ cell mutagenic, or toxic for reproduction and it does
not meet the criteria of CLP Regulation (EC) No 1272/2008 to be
classified for specific target organ toxicity after repeated exposure
evidence of chronic toxicity.
A definitive conclusion about the
T-criterion cannot be reached.
