Results and discussion
In vivo
Results
- Irritation parameter:
- primary dermal irritation index (PDII)
- Basis:
- mean
- Time point:
- other: up to 14 days
- Score:
- 0.42
- Remarks on result:
- other: mean score from all readings were averaged
- Irritant / corrosive response data:
- Some animals showed temporary very slight erythema as well as well-defined erythema, but all irritations subssided by 14 days. No relevant edema were observed. Hence, minimal to mild, transient irritation was noted. The animals did not exhibit any abnormal clinical signs for the duration of the study.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The estimated primary irritation index is 0.42. Minimal to mild, transient irritation was noted. All induced erythema subsided within 14 days after exposure. The animals did not exhibit any abnormal clinical signs for the duration of the study.
According to EU classification, the item does not has to be classified
According to GHS classification, the item does not has to be classified - Executive summary:
The dermal irritation of Propargyl-N-butylcarbamat
was determined in rabbits according to the EPA guideline EPA OTS 798.4470 (Acute Dermal Irritation). The scoring was done in accordance with the method of Draize. The estimated primary irritation index was 0.42 and hence minimal to mild, transient irritation was noted. All induced erythema subsided within 14 days after exposure. The animals did not exhibit any abnormal clinical signs for the duration of the study.The results showed short term mild irritation. The limits for classification were not surpassed. Concluding, Propargyl-N-butylcarbamat
does not have to be classified as skin irritant.
