- mouse
- Strain:
- CBA
- Sex:
- female
Study design: in vivo (LLNA)

Results and discussion
In vivo (LLNA)
Results
- Parameter:
- SI
- Remarks on result:
- other: see Remark
- Remarks:
- None of the 3 concentrations tested reached the stimulation index of 3: The stimulation index at a concentration of 12.5% was of 2.6 The stimulation index at a concentration of 25% was of 1.9 The stimulation index at a concentration of 50% was of 2.5
Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- The EC3 value (derived by linear interpolation) could not be calculated as the
stimulation indices of all concentrations were below 3.
Consequently, according to OECD 429 and the criteria given in Annex I of Regulation (EC) 1272/2008, the test item Oxalic Acid, as described in this report is expected to have no sensitising properties and therefore, should not be regarded as a dermal sensitiser
