Description of key information
2EHDPP is a “poorly soluble” substance with tendency to stay undissolved when its concentration exceed the water solubility value. Effects observed in the presence of undissolved test material are not indicative of true toxicity but rather indicates physical effects.
Key value for chemical safety assessment
