Additional information

Experimental data on toxicity of 3 -aminopropan-1 -ol to aquatic invertebrates are available.

As key study a static test was performed conducted according to OECD 202 using Daphnia magna as a test organism (BASF AG, rep. no.: 1/0022/2/89, 1989). In unbuffered test solutions, the 48h EC50 was determined to be >500 mg/L (nominal), based on nominal test concentrations.

The test concentrations were not analytically verified. However, the substance is assumed to be stable due to the substances' water solubility (e.g. see IUCLID Chapter 4.8 ), its low vapor pressure (VP = 0.149 hPa @25°C; BASF AG, 1992) and its low Henry's Law Constant (HLC = 4.95E-05 Pa m³/mol, calculated with the EPI Suite v4.11, BASF SE 2016). Moreover, it is concluded, that the significant adsorption is not expected for the substance (KOCWIN v2.00, EPISuite v4.11: log Koc = 0.33 (MCI Method), logKoc = -0.13 (Kow method) / Franco&Trapp, log Koc at pH 7 = 1.19, pKa= 10.22, SPARC v4.6)

It can be concluded that the substance is with high probability acutely not harmful to aquatic invertebrates.
