Administration / exposure

Route of administration:
oral: drinking water
Vehicle:
water
Details on oral exposure:
In the first and second step of the study, 2.0006 g and 2.0061 g of the test item were weighed and
distilled water was added to two 10 mL volumetric flasks. Just before the administration, the
preparations were stirred using a vortex during 30 seconds to dark red solutions.
Doses:
2000 mg/kg
No. of animals per sex per dose:
Group treated (2000 mg/kg): 3 female rats
Control animals:
yes
Remarks:
Clinical examinations: Nothing to report. Animal normal (3/3)
Details on study design:
This examination focuses particularly on a list of symptoms, recorded as "present" or "absent" on the
observation sheet.
Statistics:
Systematic examinations were carried out to identify any behavioural or toxic effects on the major
physiological functions 30 min, 1h, 3h, 4h, 24h, 48h after administration of the test item and continued
daily during 14 days.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The LD50 of the test item Red EHS 237 is higher than 2000 mg/kg body weight.
In accordance with the O.E.C.D. Test Guideline No. 423, the LD50 cut-off of the test item may be
considered as 5000 mg/kg body weight by oral route in the rat.
