- Irritant / corrosive response data:
- 4.5 hours after the application of Slz WX-R, all of the cases (3 cases) showed erythema and edema in both the wounded site and the non-wounded site with a strength level of 1, at approximately the same extent for both findings. By 24 hours after application, the erythema had increased in intensity to a strength level of 2 in all of the cases, while the edema ranged in strength from 1 to 2. However, these local reactions gradually lessened, and by 1 week after application, all of the local reactions had disappeared.
The primary irritation rate that was calculated based on the above-noted results was 2.83, indicating that Slz WX-R will show moderate irritation of rabbit skin. - Other effects:
- none

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- A study in 3 rabbits revealed that Slz WX-R 6 was moderately irritanting after 4-hour exposure. The study was not performed according to the general guidelines for acute dermal irritation/corrosion under GLP conditions, but was well performed and documented and as such considered reliable with minor restrictions.
