- Irritant / corrosive response data:
- Severe skin reactions were observed at the rabbits. Even at the end of the observation period, one animal showed irreversible effects.
The third animal showed a complete destruction of the skin on the whole patch area , therefore a scoring was not possible.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1C (corrosive) based on GHS criteria
- Conclusions:
- The animals showed moderate to severe skin reactions which were only partial reversible. One animal showed a complete destruction of the skin on the whole patch area.
Based on the irritation/corrosion data available, the substance will be classified as skin corrosion/irritation: Sub-category 1 C, H314 according to Regulation 1272/2008/EEC (CLP). - Executive summary:
The potential for acute skin irritation of Magnesium-monoperoxyphthalat was investigated according to the OECD Guideline 404 “Acute Dermal Irritation/Corrosion”, 1992 and EEC Guideline B.4 “Acute toxicity (Skin -irritation/Corrosion)”, Jan 1997. Three female rabbits (strain Chbb:HM(SPF) – Littlerussian) received an amount of 0.5g each of the test item on the left and right dermal side of the trunk. The exposure duration was 4 hours under semioccclusive conditions. The skin was assessed for signs of irritation 1h, 24h, 48h, 72h , 7 d, 14 d, 21 d and 28 d after administration. The animals showed moderate to severe skin reactions which were only partial reversible. One animal showed a complete destruction of the skin on the whole patch area. Based on the irritation/corrosion data available, the substance will be classified as skin corrosion/irritation: Sub-category 1 C, H314 according to Regulation 1272/2008/EEC (CLP).
