 Health:

 Health Summary: Not absorbed from the skin, moderate absorption from 

the lung and GI tract (pchem); the PMN substance is expected to be an alkylating agent. 

Concern for acute toxicity and irritation to eyes, mucous membranes and lungs based on 

submitted test data; oncogenicity, mutagenicity, and developmental toxicity based on alkylation 

and test data for tris(2-chloroethyl) phosphate (TCEP; NTP TR-391). Also concern for 

neurotoxicity (NTP TR-391) and reproductive toxicity (RAC92040) based on TCEP. Concern 

for immunotoxicity based on copper.

 Test Data: (-) Salmonella with and without activation; rat oral LD50 

= 894 mg/kg (M), 564 mg/kg (F); no skin irritation in rabbits; slight to moderate eye irritation in 

rabbits; no skin sensitization in guinea pigs using the Magnusson-Kligman assay at 12% ai

Initial Submission Review

Daphnid Ecotoxicity Test: 

The Bayer AG WD-UWS Institute of Environmental Analysis conducted a 48-hour acute 

toxicity test in water fleas (Daphnia magna) with P-13-0221 (76.9% purity) under static 

conditions. The study was reported to follow Council Directive 92/69/EEC C.2 (1992). Two 

replicates of 10 D. magna were exposed to a dilution water control (M4 medium) or the PMN 

substance as a water accommodated fraction (WAF) at the nominal loading rates of 0.1, 0.32, 1, 

3.2, 10, 31.6 or 100 mg/L. To produce the WAFs, the test substance was weighed into water, 

treated for 60 seconds at 8000 rpm with an ultra-turrax and afterwards stirred for 24 hours with a 

magnetic stirrer. To remove undissolved particles, the resulting emulsions were filtered using 

folded filters of the pore size 7 – 12 μm. Considering the heterogeneous composition of the test 

substance, WAFs were tested. No analysis was performed. Over the course of testing, 

temperature ranged from 19.9 – 20.3 ̊C, pH ranged from 8.0 – 8.3 and dissolved oxygen ranged 

from 8.4 – 9.0 mg/L. The dilution water hardness was 267.72 mg CaCO3/L. A loading rate of 

500 daphnids/L was calculated. No immobilization was observed at nominal loading rates ≤ 1 

mg/L. At nominal loading rates of 3.2, 10, 31.6 and 100 mg/L, immobilization of 20%, 100%, 

100% and 100% were observed, respectively. No EC50 value was reported. The 48-hour EL0 

and EL100 are 1 and 10 mg/L, respectively. The geometric mean of the EL0 and EL100 is 3.16 

mg/L. This study is not acceptable because the test material was filtered. Also, it is unclear that 

the loading rates concentrations are comparable with the actual concentrations of the test 

material. The reported chronic ChV is 3.16 mg/L

48-hour ChV = 3.16 mg/L
