Description of key information

The NOEL for the  Mus musculus   was 500 mg/kg bw  exprssed as 2-(2-butoxyethoxy)ethanol.  On a molecular weight scaled basis, the NOEL  for 2-(2-(2-butoxyethoxy)ethoxy)ethanol would be 635.5 mg/kg bw day.  (500 x 206.28) / 162.3.=635.5 mg/kg bw/day 
Conversion factors from NOEL to NOEC for mammalian species Mus musculus is 8.3 (bw/dfi)  NOECmouse=635.5x 8.3=5274.7 mg/kg/diet

Key value for chemical safety assessment

Short-term EC50 or LC50 for mammals:
26 373.3 mg/kg food
Long-term EC10, LC10 or NOEC for mammals:
5 274.7 mg/kg food

Additional information

For the assessment of secondary poisoning, the results always have to be expressed as the concentration in food in order to be able to compare it to the PEC.
