Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Description of key information

A skin sensitisation test on boric acid was performed according to OECD Guideline 406 (Buehler method; Wnorowski, 1994).

Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

Boric acid was tested in a Buehler method skin sensitisation test (Wnorowski, 1994 ) applied at a concentration of 95 % (powder moistened with water) during both the induction and challenge phase of the test. No signs of skin sensitisation were observed. No evidence of skin sensitisation in humans exposed occupationally to borates has been reported (Bruze et al., 1995).

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no study available
Additional information:

There are no data to suggest that boric acid is a respiratory sensitiser.

Justification for classification or non-classification

Boric acid is not a skin or respiratory sensitiser. In accordance with the criteria of EU CLP Regulation (EC) No 1272/2008 boric acid does not need to be classified and labelled as a skin or respiratory sensitiser.
