- Reversibility:
- no data
- Remarks on result:
- other: No data on reversibility are available, because the test was ended after 48 hours due to the observation of corrosive effects

- Score:
- 2 - 4
- Max. score:
- 4
- Reversibility:
- no data
- Remarks on result:
- other: Slight edema was observed on the initial observation and 1 hour timepoint; this increased to severe edema from the 24 hour timepoint onwards
- Irritant / corrosive response data:
- As results, necroses and scars were noted from the epidermis to the dermis. The test substance was considered corrosive and no further experiment was perfonned. No abnormality was noted in general condition, and body weight showed a satisfactory increase during the observation period.
Applicant's summary and conclusion
- Interpretation of results:
- corrosive
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- From the results described above it has been concluded that the test substance is corrosive and classified as Category 1 in the GHS classification.
- Executive summary:
In accordance with the OECD guidance document (No. 404), an acute dermal-irritation potential of 1-butanol, reaction products with 2-[(2-propen-1-yloxy) methyl] oxirane was examined in the Yoshimi Laboratories study (No. 1323). 0.5 mL of the application material impregnated into a 2.5x2.5-cm piece of lint cloth was directly applied to the application site, and the cloth was fixed with
adhesive stretch bandage. This semi-occlusive application was kept for 4 hours, and skin reaction was evaluated immediately after and 1, 24, and 48 hours after patch removal, pursuant to the table for grading of skin reactions in the guideline.
As results, reactions from severe erythema (beef redness) to eschar formation preventing grading of erythema with slight edema were noted from immediately after patch removal.
Subsequently necroses and scars were noted from the epidermis to the dermis, indicating a corrosive effect.
Thus no further experiment was performed.
Regarding the GHS classification, the test substance is classified as Category 1 for its corrosive effect.
No abnormality was noted in general condition, and body weight showed an increase during the observation period.
