Additional information
Although this substance is not inherently biodegradable it is extremely soluble (> 1000 mg/l), has a low Log Pow (-2.45) and the studies at this level indicate that it will therefore not be classified for environmental toxicity.
The three acute ecotoxicity studies were conducted at varying pH’s. An analysis of the effect of hydrolysis on the ecotoxicity test concentrations was conducted and is documented in detail in Appendix 1. At pH 7 the test concentrations varied between 0.33% and 58.53% of nominal at the end of the exposure period and at pH 9 test concentrations varied between 10.65% and 97.97% of nominal at the end of the exposure period. While the hydrolysis study was not conducted at the pH’s that the ecotoxicity studies were conducted at so the results from this analysis cannot be viewed as definitive, these results strongly suggest that it is likely that algae, fish and daphnia magna were exposed to Epofloc L-1R’s breakdown product, TEPA. It is likely that some, if not all, toxicity observed in the studies was derived from the presence of TEPA.
No reliable ecotoxicity data was available for TEPA, therefore, the ecotoxicity endpoints for Epofloc L-1R were used to represent TEPA toxicity. As the ecotoxicity endpoints are expressed as Epofloc L-1R, the assessment was conducted for ‘Epofloc L-1R equivalents’ rather than TEPA to allow comparison with the ecotoxicity data. The molecular weight for Epofloc L-1R and the physical-chemical and environmental fate parameters for TEPA were used to model fate of ‘Epofloc L-1R equivalents’. The physical-chemical and environmental fate parameters for TEPA were taken from the OECD SID for Tetraethylene pentamine (UNEP, 2001).
Conclusion on classification
The studies indicate at this level (Annex VIII) that this substance is not classified for environmental toxicity.
