- REPORTING FORMAT FOR THE ANALOGUE APPROACH
Available data from Etheramine C13i are considered to be applicable for C10i-etheramine as well. The structure of Etheramine C13i only differs from that of Etheramine C10i, in that the alkyl chain is only 2 carbons longer. This only has limited effects on physical properties, whereas chemical behaviour, reactivity and metabolism are the same. With alkylamines in general, the corrosive properties tend to increase with shortening of the alkyl chain. Therefore the results obtained from Etheramine C13i are therefore also expected to be of similar severity for Etheramine C10i. (See for more information endpoint summary Ch.7.1 Toxicokinetics)

MAXIMUM DOSE VOLUME APPLIED: 2000 mg/kg (10 mL/kg) body weight.
DOSAGE PREPARATION: The test substance was dosed undiluted as delivered by the sponsor.
CLASS METHOD
- Rationale for the selection of the starting dose: Based on anticipated mortality at the next higher dose. - Doses:
- 300 mg/kg (0.36 mL/kg) body weight
2000 mg/kg (2.38 mL/kg) body weight.
Dose volume calculated as dose level (g/kg) / density (g/mL) - No. of animals per sex per dose:

- no
- Details on study design:
- The toxicity of the test substance was assessed by stepwise treatment of groups of 3 females. The first group was treated at a dose level of 300 mg/kg. The absence or presence of mortality of animals dosed at one step determined the next step, based on the test procedure defined in the guidelines. The onset, duration and severity of the signs of toxicity were taken into account for determination of the time interval between the dose groups.
Animals were deprived of food overnight prior to dosing and until 3-4 hours after administration of the test
substance. Water was available ad libitum.
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Mortality/Viability: Twice daily
Body weights: Days 1 (pre-administration), 8 and 15 and at death (if found dead or sacrificed after Day 1).
Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15. The
symptoms were graded according to fixed scales and the time of onset, degree and duration were recorded.
- Necropsy of survivors performed: yes
- Other examinations performed: none. - Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50
value). - Sex:

- Executive summary:
The acute oral toxicity of 3-(Isotridecyloxy)-1-propane amine in the rat was studied according to the Acute Toxic Class Method.
Initially, 3-(Isotridecyloxy)-1-propane amine was administered by oral gavage to three female Wistar rats at 300 mg/kg body weight. In a stepwise procedure additional groups of females were dosed at 2000 mg/kg body weight. All animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed on the day of death or after terminal sacrifice (Day 15).
The incidence of mortality was as follows, presented in chronological order of treatment:
300 mg/kg 1/3
300 mg/kg 0/3
2000 mg/kg 3/3
The decedents and moribund animals were found dead or sacrificed in moribund condition on Day 4 (300 mg/kg) or between days 2 and 3 post-treatment (2000 mg/kg).
Clinical signs observed during the study period were as follows:
300 mg/kg: Hunched posture, piloerection, lethargy, labored respiration, rales, watery discharge from the eye, chromodacryorrhoea and/or salivation (all animals).
2000 mg/kg: Restless behaviour, lethargy, hunched posture, uncoordinated movements, shallow respiration, piloerection, diarrhoea, salivation, chromodacryorrhoea, lean appearance and/or ptosis (all animals).
The surviving animals at 300 mg/kg had recovered from the symptoms by Day 6.
Weight loss was observed for the female at 300 mg/kg found dead on Day 4 and for two females at 2000 mg/kg found dead/sacrificed on Day 3. Surviving females at 300 mg/kg showed normal body weighty gain.
The following macroscopic post mortem findings were recorded:
300 mg/kg : Cannibalism and irregular surface of the forestomach (female found dead).
2000 mg/kg : Gelatinous gastro-intestinal tract (one animal) or beginning stage of autolysis (one animal).
The oral LD50 value of 3-(Isotridecyloxy)-1-propane amine in Wistar rats was established to be within the range of 300-2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to be 500 mg/kg body weight.
