Conclusion on classification

Classification related key information

Biodegradation: not readily biodegradable

Bioaccumulation: no potential for bioaccumulation

Acute toxicity:

-             Fish: no acute toxic effects up to the limit of water solubility (read across)

-            Aquatic invertebrates: no acute toxic effects up to the limit of water solubility (read across)

-            Aquatic algae: no acute toxic effects up to the limit of water solubility (read across)

Chronic toxicity: 

-            Fish: no chronic toxic effects up to the limit of water solubility (read across)

-           Aquatic algae: no chronic toxic effects up to the limit of water solubility (read across)

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.
