Details on dermal exposure:

TEST SITE
- Area of exposure: approximately 10% dorsal skin area of each rat was clipped free of hair without any abrasion 24h before the test
- % coverage: 10%
- Type of wrap if used: porous gauze dressing and non irritating adhesive tape

REMOVAL OF TEST SUBSTANCE
- Washing: the residual test item was wiped gently from the skin using cotton soaked with water
- Time after start of exposure: 24 hours

TEST MATERIAL
- Amount(s) applied: 2000 mg/kg bw
- Concentration: undiluted

Duration of exposure:

24 hours

Doses:

2000 mg/kg bw

No. of animals per sex per dose:

- Range-finding test: 1 male and 1 female
- Limit test: 5 males and 5 females

Control animals:

not required

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
> body weight: body weight of each animal was recorded just prior to application of dose (day 0) and on days 7 and 14 following the dosing
> mortality: all animals were observed for mortality daily throughout the observation period
> toxicity signs: all animals were observed for clinical signs of toxicity soon after dosing and once daily throughout the observation period until day 14
- Necropsy of survivors performed: yes

Statistics:

not applicable

Results and discussion

Preliminary study:

mortality was not observed at 2000 mg/kg bw in the range-finding study

Effect levels

Sex:

male/female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Remarks on result:

other: no mortality observed

Mortality:

No mortality was observed in animals treated with the test item throughout the observation period.

Clinical signs:

No clinical signs of toxicity were observed in animals treated with the test item throughout the observation period.

Body weight:

All the animals showed a normal trend of body weight gain on days 7 and 14.

Gross pathology:

The lesions observed i nthis study matched with the historical gross pathology data. Hence the lesions cannot 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 dermal application

Executive summary:

In an acute dermal toxicity study (Venkatasubramani R, 2008), groups of Wistar rats (5/sex) were dermally exposed to Vegeflux soy undiluted for 24 hours to 10% of body surface area at doses of 2000 mg/kg bw. Animals then were observed for 14 days. The test was performed according to OECD guideline 402 and GLP.

 

Dermal LD50 (Males & Females) > 2000 mg/kg bw (limit test)

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 males and females by dermal application. Vegeflux soy is not classified as dangerous according to EU criteria, by dermal application.
