Conclusion on classification

  1) Classification according to Regulation (EC) No 1272/2008 (CLP)


Classification according to Regulation (EC) No 1272/2008 (CLP) is performed independently for acute and chronic hazards.


Acute hazard category:


The only experimental acute aquatic toxicity value was determined for fish (Danio rerio, RL2). The LC50(96 h) was 20.5 mg/L. Thus,the submission substance is not classified for acute aquatic toxicity.


Chronic hazard category:


Decisive for the applied classification scheme is failure or fulfilment of (1) rapid degradability and (2) absence of a bioaccumulation potential.

As substitute for an experimentally determined BCF in fish log KOWis taken as an indicator of bioaccumulation potential. As log KOWof the submission substance is clearly below the cut-off value according to CLP of 4.0 (2.7),the submission substance is regarded as non-bioaccumulative.

Rapid biodegradability according to CLP is given for substances which were assessed as “readily biodegradable” in screening studies (OECD 301) with a minimum of 60% CO2-generation or oxygen consumption of theoretical maximum within 28 days and at the same time fulfilment of the 10-day-window. No experimental data on biodegradability of the submission substance itself are available. However, by weight of evidence from read across to benzoic acid methyl ester (in accordance with US EPA HPV programme) and results from different QSAR models for the submission substance itself it is concluded, thatthe submission substance is readily biodegradable.

In conclusion,the submission substance is not classified for chronic aquatic toxicity.


2)             Classification according Directive 67/548/EEC (DSD)


In principle, the same aspects apply in respect of a potential for bioaccumulation and ready biodegradability as outlined above for classification according to CLP regulation.

Thus, according to Directive 67/548/EEC the submission substance is not classified for aquatic toxicity.
