Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information
- Conclusions:
- Based on these results and according to the:
- OECD Harmonized lntegrated Hazard Classification System for Human Health and Environmental Effects of Chemical Substances (OECD, 1998), A 132 does not have to be classified for skin irritation.
- EC criteria for classification and labelling requirements for dangerous substances and preparations (Council Directive 67/548/EEC), A 132 does not have to be classified and has no obligatory labelling requirement for skin irritation. - Executive summary:
Primary skin irritation/corrosion study with A 132 in the rabbit (4-hour semiocclusive application).
The study was carried out based an the guidelines described in: OECD No.404, "Acute Dermal lrritation/Corrosion" (2002); EC Commission Directive 92/69/EEC, B.4, "Acute Toxicity - Skin irritation" (1992); US EPA, OPPTS 870.2500, Acute Dermal Irritation (1998) and JMAFF, Japanese Test Guidelines (2000).
Three rabbits were exposed to 0.5 grams of A 132, applied onto clipped skin for 4 hours using a semi-occlusive dressing. Observations were made 1, 24, 48 and 72 hours after exposure.
No skin irritation was caused by 4 hours exposure to A 132.
Brownish staining of the treated skin by the test substance was observed during the observation period, which did not hamper the scoring of the skin reactions.
Based on these results and according to the:
- OECD Harmonized lntegrated Hazard Classification System for Human Health and Environmental Effects of Chemical Substances (OECD, 1998), A 132 does not have to be classified for skin irritation.
- EC criteria for classification and labelling requirements for dangerous substances and preparations (Council Directive 67/548/EEC), A 132 does not have to be classified and has no obligatory labelling requirement for skin irritation.
