- Housing: up to 4 animals/group, suspended solid-floor polypropylene cages furnished with woodflakes
- Diet: ad libitum
- Water: ad libitum
- Acclimation period: at least 5 days

ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19-25
- Humidity (%): 30-70
- Air changes (per hr): AT LEAST 15

Administration / exposure

Route of administration:

oral: gavage

Vehicle:

unchanged (no vehicle)

Details on oral exposure:

VEHICLE
- Concentration in vehicle: no vehicle used
MAXIMUM DOSE VOLUME APPLIED: 10 ml/kg

In the absence of toxicity data of the test material a dose of 300 mg/kg bw was applied initially to one animal. Since no mortality was observed 1 more animal was used to test the higher dose of 2000 mg/kg bw. No mortality was detected; four aditional animals were treated with a single gavage dose of 2000 mg/kg bw.

Doses:

300 and 2000 mg/kg bw

No. of animals per sex per dose:

One animal tested at 300 mg/kg bw, five animals treated with 2000 mg/kg bw.

Control animals:

no

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: 0.5, 1, 2 and 4 h post-treatment and daily for 14 days. Morbity/mortality checks twice per day. Weighing on Day 0, Day 7 and Day 14.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, gross necropsy.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Under the conditions of this test, benzenesulfonic acid, 4-C10-13-sec-alkyl derivs.-, compd. with 2-propanamine has an oral discriminating dose higher than 2000 mg/kg bw.

Executive summary:

In the preliminary phase of an acute oral toxicity study (fixed dose) fasted young adult female Wistar rats (one per dose) were given a single oral dose of  benzenesulfonic acid, 4-C10-13-sec-alkyl derivs.-, compd. with 2-propanamine (1:1) (97%) at doses of   300 or 2000  mg/kg bw. No effects on the animals were seen at both dose levels, and therefore, the main study was performed with the higher dose of 2000 mg/kg bw, as a solution in arachis oil BP.

 

 Oral LD₅₀females> 2000 mg/kg bw

No adverse effects were detected.   

Benzenesulfonic acid, 4-C10-13-sec-alkyl derivs.-, compd. with 2-propanamine (1:1) is of low toxicity based on an LD₅₀ higher than the classification criterion. The substance shall not be labelled for acute oral toxicity.
