Description of key information
Additional information
FBSEE diol is used by the manufacturer in closed systems as a monomer or is similarly packaged for export. A limited tonnage is converted to a waxy solid form for use as a monomer. The 3M facility that manufactures and uses FBSEE diol internally contains ventilation to control worker exposure to vapors. All 3M manufacture and use of FBSEE diol in the EU will be at a location where multiple treatment technologies are applied in series to process wastewater. The final treatment stage incorporates granular activated carbon (GAC) filtration. No direct release to surface water is expected. Solid waste from the manufacturing process and sewage sludge is incinerated. Indirect release to soil by application of sewage sludge will not occur. None of the uses of FBSEE diol result in direct release to soil.
FBSEE diol has a vapor pressure of 0.023 Pa at 20 °C and is moderately soluble (531 mg/L at 22±2 °C). A limited quantity of FBSEE diol may be released directly to the atmosphere during manufacture and use. The physical/chemical properties indicate that any FBSEE diol released to the atmospheric compartment will be removed by wet or dry deposition.
Limited biodegradation of FBSEE diol (26 %BOD) was observed in an OECD 301 F assay. In an inherent biodegradability test, the predominant metabolite of was 2,2’-{ [(Nonafluorobutyl)-sulfonyl]imino} diacetic acid. Other materials detected were N-(2-Hydroxyethyl)-perfluorobutane sulfonamide, Perfluorobutane sulfonamide, Perfluorobutane sulfinic acid, and Perfluorobutane sulfonic acid. Perfluorobutanoic acid was examined but not detected. In a specific test addressing volatile products, n-1H-nonafluorobutane and iso-1H-nonafluorobutane were detected at low levels, and Perfluorobutane sulfonic acid was not detected. Mass balance as a % of theoretical for targeted degradation products ranged from 98% at day 7 to 92.8% at day 42 where there was total loss FBSEE Diol. Mass balances were essentially complete by Day 3 of the experiment. The concentration of FBSEE diol did not change notably in a preliminary hydrolysis study done at 50 °C (OECD 111). A hydrolysis half-life >1 year was reported based on this result (i.e, it is considered hydrolytically stable). As noted above, no direct releases of FBSEE diol are expected to aquatic systems due to process controls.
FBSEE diol has a measured log Kow of 2.7 (shake-flask method). It is not expected to be bioaccumulative according to screening criteria in Technical Guidance Chapter R.11 on PBT Analysis. Further, little or no release of FBSEE diol as such to aquatic systems is expected, and direct and indirect exposure of the aquatic compartment is not expected.
Summary: FBSEE diol is used as a monomer in industrial applications. Operational conditions and risk management measures result in low expected release to the environment.
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).
