Conclusion on classification
Diphosphoric acid, compound with 1,3,5-triamine (1:2) is not readily biodegradable according to OECD criteria. Bioaccumulation is not expected based on the low log Pow of -1.24. Acute or chronic aquatic toxicity was not observed within the range of water solubility of the substance (WS: 385.6 ± 1.1 mg test item/L based on P and 233.1 ± 2.4 mg/L based on non purgeable carbon). Based on the available data the substance is not classified according to the consolidated version of Regulation (EC) No. 1272/2008 (CLP) considering all further amendments.
