Results and discussion

Effect levels
Sex:
female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Remarks on result:
other: no mortality
Mortality:
No mortality was observed in any of the animals treated with the test item
Clinical signs:
All the animals treated with the test item were found normal throughout the 14 day observation period
Body weight:
No marked changes were observed in the body weight gain of animals treated with the test item
Gross pathology:
The lesions observed were found in the study matched with the historical gross pathology data. Hence the lesions observed can not be related to the test item

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The LD50 of Vegeflux Soy is > 2000 mg/kg bw by oral intake
Executive summary:

In an acute oral toxicity study (Venkatasubramani R, 2008), groups of 8-12 weeks old Wistar rats (2 x 3 females per group) were given a single oral dose of Vegeflux Soy in 2% DMSO at doses of 300 and 2000 mg/kg bw and observed for 14 days. The test was performed according to OECD test guideline 423 and GLP.

 

Oral LD50 Females > 2000 mg/kg bw

No mortality, clinical signs, body weight changes or gross pathology changes were observed during the observation period.

 

Vegeflux Soy is of low toxicity based on the LD50 in females by gavage. Vegeflux soy is not classified as dangerous according to EU criteria, by oral intake.
