- Vehicle:
- water
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 0.2 g/mL
- Amount of vehicle (if gavage): 10 mL
- Justification for choice of vehicle: The vehicle was chosen due to its non-toxic characteristics.
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg bw
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: The starting dose was selected to be 2000 mg/kg body weight. No compound-related mortality was recorded for any animal of step 1 or 2. Based on these results and according to the acute toxic class method regime no further testing was required. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- Step 1: 3 animals and step 2: 3 animals
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Weighing was performed on day 1, 8 and 15, observations of clinical signs were performed once daily.
- 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:
- The present study was performed in order to determine the LD50 of Rhamnolipids. No premature deaths occurred and no adverse effects were observed during cage side observations and final gross necropsy. Thus, Rhamnolipids is not classified according to GHS criteria.
- Executive summary:
In an acute oral toxicity study according to OECD Guideline 423 (2001) and EU method B.1 tris (2008), groups of fasted, 9-11 weeks old female Wistar rats (2 steps, 3 animals per step) were given a single oral dose of Rhamnolipid (88.1% a.i.) in sterile water at a doses of 2000 mg/kg bw and observed for 14 days.
The test item showed no mortality and no other acute oral toxicity characteristics after a single dose administration. No specific clinical sings were observed during the whole observation period. None of the animals showed weight loss during the observation period. No specific gross pathological changes were recorded for any animal.
According to the guideline, the LD50 cut-off(rat) is >5000 mg/kg bw
