Mortality
Cages of rats were checked at least twice daily for any mortalities.
Bodyweight
The bodyweight of each rat was recorded on Days 1 (prior to dosing), 8 and 15. Individual weekly bodyweight changes were calculated.
- Necropsy of survivors performed: yes
- Other examinations performed:
Clinical signs
Animals were observed soon after dosing and at frequent intervals for the remainder of Day 1 (a period of seven hours). On subsequent days animals were observed once in the morning and again at the end of the experimental day. This latter observation was at approximately 16.30 hours on week
days or 11.30 hours on Saturdays, Sundays and public holidays. The nature and severity of the clinical signs and time were recorded at each observation. All animals were observed for 14 days after dosing. - Statistics:

- other: None of the animals died.
- Mortality:
- There were no deaths following a single oral dose of Ampholak 7CX at 5.0 g/kg bodyweight.
- Clinical signs:
- other: Piloerection was observed in all rats within five minutes of dosing. This sign persisted and was accompanied at later intervals on Day 1 by abnormal body carriage (hunched posture) and pallor of the extremities. Recovery of all rats, as judged by external

- No macroscopic abnormalities were observed for animals killed on Day 15.
Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Remarks:
- Migrated information
- Conclusions:
- The results of this study indicate that the test material has no toxic effect when administered as a single oral dose to the rat at a dose level of 5000mg/kg body weight. The composition of the test material is estimated to be 40% active ingredient (incl NaCl) and 60 % water. Therefore, based on active ingredient, the tested dose level is considered to be 2000mg/kg body weight based on Amines, N-(3-aminopropyl)-N’-C12-18-alkyltrimethylenedi-, N-(carboxymethyl)derivs., sodium salts (CAS no 2060541-51-5). Under the conditions of this study the LD50 > 2000 mg/kg bw.
- Executive summary:
A study was performed to assess the acute oral toxicity of the test material to the rat. The method followed was that described in EEC Methods for the determination of toxicity, Annex to Directive 92169lEEC (OJ No. L383A, 29.12.92), Part B, Method B. 1. Acute toxicity (oral). A group of ten fasted rats (five males and five females) was given a single dose by gavage of the test substance, as supplied, at a dose level of 5.0 g/kg bodyweight. All animals were killed and examined macroscopically on Day 15, the end of the observation period.
There were no deaths. Clinical signs of reaction to treatment consisted of piloerection, abnormal body carriage and pallor of the extremities, recovery was complete by Day 2. All rats achieved anticipated bodyweight gains throughout the study. No abnormalities were recorded at the macroscopic examination on Day 15. Based on the active ingredient of the test material, the LD50 > 2000 mg a.i./kg bw for the Amines, N-(3-aminopropyl)-N’-C12-18-alkyltrimethylenedi-, N-(carboxymethyl)derivs., sodium salts (CAS no 2060541-51-5).
