No additional data
Test system

- Irritant / corrosive response data:
- The test substance in physiological saline elicited very slight to well defined erythema at both abraded and non-abraded sites on 3/6 rabbits. Remaining rabbits showed no response to test substance at 24 h. At 72 h erythema persisted in one rabbit at both the abraded and non-abraded sites.
Very slight to slight oedema was noted on both abraded and non-abraded sites on 2 rabbits, the remaining animals showing no response on either site at 24 h. At 72 h very slight oedema persisted in one rabbit at the non-abraded site. - Other effects:
- No information provided

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test substance is a mild skin irritant to New Zealand White rabbit. However under the Regulatin (EC) No 1272/2008 it is not classified for skin irritation
- Executive summary:
Under the Regulatin (EC) No 1272/2008 the test substance, tested as 60% w/w HMX in physiological saline, is not classified for skin irritation.As per the table below the mean score for erythema/eschar or for oedema wasn't between 2.3 and 4.0 calculated between two time points: 24 and 72 hours.
