Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
Repeated dose toxicity: via oral route - systemic effects
Link to relevant study records
- Endpoint:
- repeated dose toxicity: oral, other
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Justification for type of information:
- Following daily oral intake of 6.4 mg sodium tetrafluoroborate by a volunteer for a period of 14 days, a daily average of 100% was excreted in the urine and 1.6% in the feces. The fluoride content of the volunteer's food was not determined. Sodium fluoroborate is therefore well absorbed, but the fluoride which enters the body is not stored. The authors attributed this to slow hydrolysis of the tetrafluoroborate ion. In another study with 3 volunteers and a study duration of 7 to 38 weeks, there were indications that fluoride which was absorbed in the form of sodium tetrafluoroborate was stored in the body. The amount was <10% of that absorbed into the bloodstream. In addition, as a comparison and another read-across: LD50 (oral) for potassium tetrafluoroborate = 5855 mg/kg (rat).
- Reason / purpose for cross-reference:
- read-across: supporting information
