- The acute oral lethal doses was for determined for cyclohexanecarboxylic acid in rats. Tests were performed at Food and Drug Research Laboratories, Inc., Waverly, New York or Gulf South Research Institute, New Iberia, Louisiana. Groups of ten animals, five males and five females, weighing 40 to 60 g (FDRL Strain, Waverly, New York) were fasted overnight prior to treatment. The test substance was administered by oral gavage as a solution or suspension in corn oil. The concentration of the test substance in corn oil was adjusted so that each group of animals in a particular study received the same volume of solution with respect to body weight. Animals had free access to water at all times and to feed (Purina Laboratory Chow) following dosing. Animals were closely observed for mortality and pharmacologic effects on the day of dosing and daily thereafter for a total of 14 observation days. Rats were weighed prior to dosing.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LD50 of the read across substance cyclohexanecarboxylic acid for rats is 3265 mg/kg bw. It is considered as harmful according to EU criteria and does not need to be classified.
- Executive summary:
The acute toxicity of the read across substance cyclohexanecarboxylic acid was tested on rats after oral application and was published by Moran, 1980. From this study it is shown, that the LD50 of cyclohexanecarboxylic acid is 3265 mg/kg bw. This indicates that cyclohexanecarboxylic acid is not harmful according to EU criteria. We consider that quinic acid has a similar LD50 value, so that quinic acid does not need to be considered as harmful according to EU criteria, too
