General Information

Not classified
Implementation:
EU
Remarks:
The original R52/53 labelling attributed to the substance is due to the Algae result observed in the study; this is also a limit value at >87 mg/l. However it should be noted that under the current REACH regulation for which this registration is being made, there have been some alterations to the manner in which Algal data is interpreted. It is known that the following is applicable:
1. In algal studies, the result based on growth rate shall be used for evaluation instead of those for biomass. Thus, the result of the algae study is ErC50 >87 mg/L (measured). However there is no reason to recalculate nominal concentrations with measured concentrations as long as the result of the analytical monitoring is >80% of the nominal concentration. For this reason, the actual result which should be reported within this registration under REACH should be ErC50 >100 mg/L (nominal).
2. The decrease of growth rate at the highest concentration (87/100 mg/L) was given as 23%. A further examination of the probit analysis has been undertaken by an independent consultant whom has extrapolated the original values with ToxRat (version 2.10.05), Weibull distribution.

The results of this assessment are as follows:
Based on nominal concentrations: ErC50 = 175 mg/L (95%CV: lower 145 mg/L, higher 253 mg/L).
Based on measured concentrations: ErC50 = 152 mg/L (95%CV: lower 125 mg/L, higher 221 mg/L).
As such, these revised values indicate that classification as R52/53 is no longer applicable. The substance is therefore proposed to be “not classified” for environmental effects. This CLP labelling reflects this revised classification.
