Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
