Acute Toxicity: oral
Administrative data
- Endpoint:
- acute toxicity: oral
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1973
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Remarks:
- The numbers of dose groups and the number of dead animals at each applied dose were not reported. This is considered a minor deficiency since a sufficient number of animals in total (50) and at least 5 animals/sex/group were used and the LD50 was calculated using a standard statistical method.

Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- Under the conditions of this assay, chlorhexidine gluconate was of low toxicity to rats. The LD50 values for male and female animals were 2270 and 2000 mg/kg, respectively.
- Executive summary:
In this older study (method comparable to OECD guideline 401) groups of at least 5 male and 5 female Wistar rats were dosed orally via gavage with chlorhexidine gluconate. The LD50 values for male and female animals were 2270 and 2000 mg/kg bw, respectively. Clinical signs included psychomotor depression, ataxia, depressed respiratory rate, sporadic incidences of ptosis, chromodacryorrhoea, epistaxis and diarrhea.
Under the conditions of the assay, chlorhexidine gluconate was of low toxicity to rats.
