Description of key information
Additional information
96h-LC50 to Danio rero > 100 mg/L.
48h-EC50 to Daphnia magna > 100 mg/L.
The 21d-NOEC to Daphnia magna of the structurally related substance Ethylenediamine, ethoxylated and propoxylated (CAS 25214-63-5) in a OECD 211 guideline study is = 10 mg/l (nominal) for all endpoints.
72h-EC50 to Desmodesmus subspicatus > 100 mg/L
3 hr EC10 respiration inhibition (activated sludge) > 1000 mg/L. No inhibition was observed.
Read-across statement
No-Longer-Polymer (NLP) polyether polyols are produced by the reaction of various starter molecules with propylene oxide and/or ethylene oxide. These substances exhibit a remarkable uniformity in the physical/chemical properties which influence their fate and distribution in the environment. All NLP polyols have a full acute aquatic ecotoxicity dataset and do not exhibit acute toxicity below 100 mg/L. However, differentiation in chronic invertebrate toxicity is apparent and is based on the alcohol- or amino- starter molecules used to prepare these NLP polyols. A sub-grouping based on (i) aliphatic alcohol and amine NLP polyols, (ii) EDA- (ethylenediamine) based amino NLP polyols and (iii) o-TDA- (orthodiaminotoluene) based aromatic NLP polyols is justified (ISOPA, 2010) and toxicity is expected to be similar between substances within each of these categories. It is considered appropriate to use ‘read-across’ of data of structural analogues within each sub-grouping to fill data gaps for chronic invertebrate toxicity and derive PNECs for endpoints based on these sub-groupings
