Conclusion on classification

The short-term LC50 or EC50 values are 0.15, 0.042 and >0.1 mg/l, for fish, aquatic invertebrates and algae, respectively. All these toxicity values are well above the water solubility (11.2 ug/l) of isodecyl diphenyl phosphate (IDDPP), indicating that acute toxicity is not expected at the limit of solubility.

 

Poorly water soluble substances which do not exert acute toxicity at their limit of solubility may require a precautionary classification of R53 ‘May cause long term adverse effects in the aquatic environment’ under the DSD and Chronic Category 4 under the CLP Regulations. However, this precautionary stance is not required for IDDPP as data are available to demonstrate that it is readily biodegradable.

 

IDDPP is therefore not classified in respect of the environment under either Directive 67/548/EEC or Regulation 1272/2008/EC .
