Formic acid is classified as being highly corrosive to the skin (EC 1272/2008: Skin Corrosion 1A: H314; ECB ESIS: R35). According to the REACH regulation this precludes testing for the following endpoints
- Skin irritation (Annex VII; No. 8.1, column 2; Annex VIII; No. 8.1.1, column 2)
- eye irritation (Annex VII; No. 8.2, column 2; Annex VIII; No. 8.2.1, column 2)
- sensitisation (Annex VII; No. 8.3, column 2)
- acute toxicity (Annex VII; No. 8.5, column 2; Annex VIII; No. 8.5, column 2)
- Repeated dose testing by oral and dermal exposure is technically not possible (Annex XI Section 2). Reasons:
o The substance is corrosive in the dose range of interest for the study.
o Also, for reasons of animal welfare such studies should be avoided.
Thus, formic acid cannot be used as test substance whenever repeated doses are required. Alternatively, formate salts may be tested to examine systemic toxicity. Consequences regarding DNELs for formic acid itself are as follows:
1) Local effects prevail over systemic effects
2) Dermal DNEL:
The classification concentration limits set for skin corrosion may be used as qualitative information.

3) Oral DNEL, consumer exposure
The classification concentration limits set for skin corrosion may be used as qualitative information.
4) Inhalation DNEL, worker
There is an EU Indicative Occupational Exposure Limit (IOEL) of 5 ppm (9 mg/m³; STEL: 9 mg/m³) published in the regulation 2006/15/EC that may be used directly for the inhalation DNEL,workers. As the IOEL is based on irritating properties, there is no additional factor for a short term exposure.
National German formic acid OELs are as follows:
- Binding Federal AGW: 5 ppm (9.5 mg/m³; STEL: factor 2). OEL set in 01/2006. Reference: TRGS 900 (02 July 2009)
- MAK-value: 5 ppm (9.5 mg/m³; STEL: factor 2). Reference: Deutsche Forschungsgemeinschaft (2006) MAK- und BAT-Werte-Liste 2009. Wiley-VCH, Weinheim. A document on the delineation of the MAK-value is publicly accessible. Reference: H.Greim, ed. (2003) Occupational Medicine 19, 169-180.
The pungent odor of formic acid is a warning sign that indicates exposure to formic acid and prevents extended exposure periods or exposure towards irritating concentrations. It can be reasonably assumed that the inhalation DNELs for local effects do also protect against systemic effects.

3) Oral DNEL, consumer exposure
The classification concentration limits set for skin corrosion may be used as qualitative information.
4) Inhalation DNEL, worker and consumer
There is an EU Indicative Occupational Exposure Limit (IOEL) of 5 ppm (9 mg/m³; STEL: 9 mg/m³) published in the regulation 2006/15/EC that may be used directly for workers. The IOEL is based on the irritating properties. Therefore, this concentration can also be used for consumers without corrections for differences regarding exposure period and respiration volumes between workers and consumers. However, an assesment factor of 3 (AF=3) should be applied in order to account for sensitive consumer subpopulations and possible continuous exposure. Therefore, the inhalation DNEL, consumer is set at 3 mg/m³. The pungent odor of formic acid is a warning sign that indicates exposure to formic acid and prevents extended exposure periods or exposure towards irritating concentrations.
It can be reasonably assumed that the inhalation DNELs for local effects do also protect against systemic effects.
