Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Doses:
- 630 (only females), 1000, 1600, 2500, 3150 (only males) and 4000 (only males)
- No. of animals per sex per dose:
- 5
- Control animals:
- not specified
- Details on study design:
- The test substance was applied by oral gavage at dosages of 630, 1000, 1600, 2500, 3150,
and 4000 mg/kg bw to groups of 5 male and/or 5 female rats. The lowest dose was
administered to 5 females only. The two highest doses were administered to male rats only.
The animals were checked daily for mortality and clinical signs. Body weights were recorded
at start and on days 7 and 14. Animals were observed for 14 days. Animals that died during
the test and all surviving animals at the end of the observation period were submitted to
gross necropsy. - Statistics:
- The LD50 values were for the test substance calculated to be 2970 and 1550 mg/kg bw for male and female rats, respectively (test substance: 28-30% cetrimonium chloride) . I.e LD50 values calculated as 100% cetrimonium chloride: 891 mg/kg bw and 465 mg/kg.

Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category IV
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LD50 values were calculated to be 2970 and 1550 mg/kg bw (test substance 28-30% cetrimonium chloride in water) for male and female rats, respectively.
Read across from these data on cetrimonium chloride to cetrimonium bromide indicates according to the CLP criteria that cetrimonium bromide should be classified as Acute tox. 4; H302. - Executive summary:
The test substance (test substance 28-30% cetrimonium chloride in water) was administered by oral gavage at dosages of 630, 1000, 1600, 2500, 3150, and 4000 mg/kg bw to groups of 5 male and/or 5 female rats. The lowest dose was administered to 5 females only. The two highest doses were administered to male rats only. The animals were checked daily for mortality and clinical signs. Body weights were recorded at start and on days 7 and 14. Animals were observed for 14 days. Animals that died during
the test and all surviving animals at the end of the observation period were submitted to gross necropsy.
During the first days after administration, animals of all treated groups showed decreased motor activity, squatting posture, sunken flanks, half-closed eyes, piloerection, pale skin, laboured irregular respiration, miosis and diarrhoea. All clinical signs had completely ceased by day 10. Except for one male of the 1000-mg/kg bw group that was found dead on day 13, all deaths
occurred within the first 5 days. The LD50 values (test substance 28-30% cetrimonium chloride in water) were calculated to be 2970 and 1550 mg/kg bw for male and female rats, respectively. I.e. LD50 values calculated as 100% cetrimonium chloride: 891 mg/kg bw and 465 mg/kg bw.
