- Details on study design:
- INITIAL AND CONFIRMATORY TEST
Prior to the initial test the pH of the test substance in water (saturated, sedimented suspension, 5.55 % w/v) was determined (pH = 7.46).
The in vivo test was performed initially using one animal. The first patch was removed after three minutes. No serious skin reaction was observed, therefore a second patch was applied at a different site and removed after one hour. No serious skin reaction was observed, therefore a third patch was applied at a different site and removed after four hours.
Because of a negative response after the initial test, two additional animals were exposed simultaneously. A single patch was applied to both animals for 4 hours.
TEST SITE
- Area of exposure: dorsal area of the trunk (area: approx. 6 cm²)
- Type of wrap if used: test substance was applied to the clipped skin and covered with a gauze patch (compress for operation, 8-fold), which was held in place with a non-irritating tape.
REMOVAL OF TEST SUBSTANCE
- Washing: residual test substance was removed, using water without altering the existing response or the integrity of the epidermis
- Time after start of exposure: 4 hours
OBSERVATION TIME POINTS (4 hour application time)
immediately (initial test only) as well as 1, 24, 48, and 72 hours after removal of the patch
SCORING SYSTEM: according to the Draize scale

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance is not irritating to the skin based on an in vivo study (OECD 404).
According to Regulation (EC) No 1272/2008 and subsequent adaptations, the substance does not require classification as skin irritant.
