Conclusions:
Using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, the toxicity on algae was predicted for 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (Cas no. 27059-08-1). Effect concentration i.e EC50 value was estimated to be 430.03 mg/l for Desmodesmus subspicatus for 72 hrs duration.
Executive summary:

Using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, the toxicity on algae was predicted for 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (Cas no. 27059-08-1). Effect concentration i.e EC50 value was estimated to be 430.03 mg/l for Desmodesmus subspicatus for 72 hrs duration. It was concluded that the 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (Cas no. 27059-08-1) was likely to be not-toxic to aquatic algae, hence it can be considered to be “not classified” as per the CLP classification criteria for aquatic environment.

Additional information

Toxicity to aquatic algae and cyanobacteria

Four studies including predicted data from validated tools and experimental data from peer reviewed journal and authorative database for toxicity to aquatic algae endpoint of test chemical 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (CAS: 27059-08-1) with relevant read across which is close to target using log Kow as primary descriptor were summarised as follows:

 

Using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, the toxicity on algae was predicted for 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (Cas no. 27059-08-1). Effect concentration i.e EC50 value was estimated to be 430.03 mg/l for Desmodesmus subspicatus for 72 hrs duration.

 

Similar prediction by EPI suite, ECOSAR version 1.1, on the basis of similarity of structure to chemicals for which the aquatic toxicity has been previously measured by structure-activity relationships (SARs) program suggest the EC50 value for toxicity to aquatic algae was predicted. On the basis of EPI suite, ECOSAR version 1.1, the EC50 value for toxicity to aquatic algae was predicted to be 320.34 mg/l for 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate in 48 hrs.

 

Above both predicted results of target assist by experimental result of read across chemical Propyl acetate (Cas no. 109-60-4) from peer reviewed journal Environmental Science and Pollution Research; 2006 which suggests that No observable effect concentration for Scenedesmus subspicatus at (>=49 <=79) Minute(s) is 250 mg/L. On the basis of the value it can be concluded that the Propyl acetate is not toxic to aquatic environment.

 

One another read across Ethylene di(acetate (Cas no.111-55-7) from High Production Volume Information System data base; 2001 which suggestsThe 72hour NOEC for Ethylene di(acetate) was determined to be 119.86 mg/L (highest concentration tested). It can be concluded that the Ethylene di(acetate) is not toxic to aquatic environment.

 

Thus based on the all available effect concentrations which is in the range of 119.86 mg/l to 430.03 mg/l for target and read across chemicals which come to the conclusion that test substance 2,2'-[(3-acetamidophenyl)imino]diethyl diacetate (Cas no. 27059-08-1) was likely to be non-toxic to aquatic algae at environmentally relevant concentrations and can be considered to be“not classified”as per the CLP regulation.
