Additional information

The endpoint study summary for 2-Propenoic acid, methyl ester, reaction products with 2-ethyl-1-hexanamine and sodium hydroxide (methanol free) is linked to study record(s) on the substance itself but also to study record(s) on an analogue substance, a.k.a. Sodium 3-[(2-carboxyethyl)(2-ethylhexyl)amino]propanoate (CAS RN 94441-92-6 / EC 305-318-6). The latter is used as source substance to fill datagaps on 2-Propenoic acid, methyl ester, reaction products with 2-ethyl-1-hexanamine and sodium hydroxide (methanol free) for particular endpoints pertaining to environmental fate, aquatic toxicity and human health toxicity. Several physico-chemical data are thus reported for the source substance (e.g.physical state, melting point, vapour pressure, surface tension, water solubility and n-octanol/water partition coefficient – identified as “supporting studies”) to support the read-across approach (cf. read-across justification document attached in "13 Assessment reports").
