CAS number: 100-85-6
Short-term toxicity results for fish, Daphnia
and algae are available for the substance. The 96h-LC50 for fish was
> 100 mg t.i./L. The 48h-EC50 for Daphnia magna was 21 mg
t.i./L. The 72h-ErC50 and 72h-ErC10 for algae were > 100 mg t.i./L,
respectively. The 72h-NOErC was 100 mg t.i./L. The substance is readily
Short-term (acute) aquatic hazard
According to Table 4.1.0(a) of the CLP
regulation, the substance does not need to be classified for acute
hazards as the 96h-LC50 for fish, 48h-EC50 for Daphnia and
72h-ErC50 for algae are all > 1 mg/L.
Long-term (chronic) aquatic hazard
The only available chronic value is
the 72h-ErC10 for algae. The chronic classification has to be determined
based on this chronic value according to Table 4.1.0 (b) (ii) (as the
substance is readily biodegradable) and based on the available LC50
value for fish and EC50 value for Daphnia, and environmental fate
data according to Table 4.1.0 (b) (iii). The most stringent outcome is
- The 72h-NOEC value for algae is > 1
mg/L, therefore the substance does not need to be classified for chronic
hazards based on this available chronic value.
- The 48h-EC50 value for Daphnia
is > 10 - <= 100 mg/L, however the substance is rapidly biodegradable.
Therefore, the substance does not need to be classified for chronic
is therefore concluded that the substance does not need to be classified
for acute or chronic environmental hazards according to the CLP
