Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Skin sensitisation

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

Studies using calcium formate are not known to exist, but results from a supporting formate salt may be read across.

Potassium diformate (1:2) was not sensitizing in a Guinea pig maximization test (10 controls, 20 test animals) that was conducted according to OECD 406 and under GLP. The concentration of the test substance was 0.5 and 15% dissolved in purified water during induction and 10% at challenge; the test concentrations were selected following preliminary studies. No skin reactions were seen in the 20 test and 10 control animals at 24 or 48 hours after challenge. Potassium diformate, therefore, is not a skin sensitiser (Covance Laboratories, 1998).


The study is considered to be full valid and suitable for assessment. This result can be extrapolated to calcium diformate.

Migrated from Short description of key information:
Formic acid and formate salts including calcium diformate lack a sensitising potential.

Justification for classification or non-classification

No classification required. Criteria of regulations 67/548/EC and 1272 /2008/EC not met.
