Administration / exposure

Type of coverage:

Vehicle:

other: The test substance was dosed undiluted as delivered by the sponsor.

Duration of exposure:

24 h

5

Results and discussion

Effect levels

Sex:

male/female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Based on:

test mat.

Mortality:

No mortality occurred.

Clinical signs:

Piloerection and chromodacryorrhoea (snout) were noted among the animals. The animals had recovered from the symptoms between Days 1 and 7.

Body weight:

The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity.

Gross pathology:

No abnormalities were found at macroscopic post mortem examination of the animals.

Other findings:

Signs of toxicity (local): Scales and/or general or maculate erythema were seen in the treated skin-area of the animals during the observation period.

Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The dermal LD50 value of Radiagreen RA in Wistar rats was established to exceed 2000 mg/kg body weight.
