Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

- Fish toxicity:

- 48-hour LC50 value: 4.27 mg/I

 

- Algae toxicity:

- The effect of P-PP test item was assessed on algal growth using the unicellular green alga Pseudokirchneriella subcapitata (Selenastrum capricornutum), over an exposure period of 72 hours.

- With respect to the inhibitory effect of the test item, the 0-72 h average specific growth rates yield and areas were significantly different from that of the control group in the examined concentration range of 0.59 - 6.33 mg/L (measured). The overall NOEC was determined as 0.32 mg/L (measured); the overall LOEC was determined as 0.59 mg/L (measured).

- The biological results are summarised in the following table:

Parameter (0-72h)     Growth rate (r) (mg/L)     Yield (y) (mg/L)     Biomass (b) (mg/L)

                                   (Calculation based on measured geometric mean concentrations)

       EC50                                 2.80                            0.86                        1.07

95% conf. limits                   2.37 – 3.30                  0.77 – 0.97            0.95 – 1.21

      NOEC                                0.32                            0.32                         0.32

      LOEC                                0.59                            0.59                         0.59

 

- Daphnia toxicity:

Under the conditions of this Daphnia magna acute immobilisation study the calculated and observed end points for the effect of P-PP were the followings:

 

- The 24h EC50 value: 3.73 mg/L(with 95% conf. limits: 3.40 - 4.10 mg/L)

- The 48h EC50 value: 2.21 mg/L(with 95% conf. limits: 2.05 - 2.39 mg/L)

-The 48h No-Observed Effect Concentration (NOEC): 0.63 mg/L

- The 48h Lowest Observed Effect Concentration (LOEC): 1.25 mg/L
