TEST MATERIAL
- Amount(s) applied (volume or weight with unit): no data; Dosages greater than 20 mL/kg could not be retained in contact with the skin. - Duration of exposure:
- 24 hours
- Doses:
- No data
- No. of animals per sex per dose:
- 4
- Control animals:
- not specified
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: no data
- Necropsy of survivors performed: no data
- Other examinations performed: clinical signs, body weight,organ weights, histopathology, other: no data - Statistics:
- Based upon mortalities during a 14-day observation period, the most probable LD50 value and its fiducial range are estimated by the method of Thompson using the Tables of Weil. The figures' in parentheses show limits of ± 1.96 standard deviations while the absence of parentheses indicates that no range is calculable because no dosage resulted in fractional mortality.

Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category III
- Remarks:
- Migrated information GHS Criteria used for interpretation of results: EU
- Conclusions:
- LD50 of 0.57 mL/kg bw (corresponding to 430 mg/kg bw) was reported for tripropylamine. According to Regulation (EC) No 1272/2008, tripropylamine should be classified in Cat 3 as acute toxic substance by dermal route (H301 Toxic in contact with skin).
- Executive summary:
Tripropylamine was tested in a range-finding toxicity study in New Zealand rabbits (Smyth et al., 1969). Penetration of rabbit skin is estimated by a technique closely akin to the one-day cuff method of Draize and associates using groups of four male albino New Zealand rabbits weighing 2.5 to 3.5 kg. The fur is removed from the entire trunk by clipping, and the dose is retained beneath an impervious plastic film. Dosages greater than 20 ml/kg cannot be retained in contact with the skin. The animals are immobilized during the 24-hour contact period, after which the film is removed and the rabbits are caged for the subsequent 14-day observation period. Based upon mortalities during 14 -day observation period, the most probable LD50 value and its fiducial range are estimated by the method of Thompson using the Tables of Weil (references are cited in the publication). LD50 of 0.57 mL/kg bw (range 0.26 - 1.23) was reported for tripropylamine. The range shows limit of± 1.96 standard deviation. Based on the density of 0.7557 g/cm³ (Lechte, 2010), 0.57 mL/kg bw corresponds to 430 mg/kg bw.
