Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Based on human data and information from animal testing formic acid is classified as corrosive to the skin and causing serious eye damage. In addition, formic acid is classified as corrosive to respiratory tract (EUH071).
Key value for chemical safety assessment
Skin irritation / corrosion
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (corrosive)
Eye irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Additional information
Formic acid is classified as corrosive to the skin and causing eye damage, based on human exposure experience and test animal data. Testing is therefore not required though no valid study according to test guidelines is known to exist.
Effects on skin irritation/corrosion: highly corrosive
Effects on eye irritation: highly corrosive
Justification for classification or non-classification
Formic acid is classified as corrosive to the skin and causing eye damage, based on human exposure experience and test animal data. Testing is therefore not required though no valid study according to test guidelines is known to exist.
Classification according to EC 67/548 considers corrosivity (C; R35). Labelling of aqueous solutions depends on the concentration of formic acid (cf. Regulation 1272/2008, p. 1067).
C; R35: C ≥ 90 %
C; R34: 10 % ≤ C < 90 %
Xi; R36/38: 2 % ≤ C < 10 %
Classification according to EC 1272/2008 is comparable, i.e. formic acid in its pure form is classified as being corrosive to the skin (category I A) and the eyes (cf. Regulation 1272/2008, p. 528). Diluted concentrations are classified as follows:
Skin Corr. 1A; H314: C≥90 %
Skin Corr. 1B; H314: 10 %≤C < 90 %
Skin Irrit. 2; H315: 2 %≤C < 10 %
Eye Irrit.2; H319: 2 %≤C < 10 %
In addition, formic acid is classified as corrosive to respiratory tract (EUH071).
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.
