Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions of this study, the test material ALUM-17 was found to be non-irritant to the rabbit skin. Therefore, no classification is required according to Regulation (EC) N° 1272-2008 (CLP) and the GHS.
- Executive summary:
In a primary dermal irritation study performed according to OECD Guideline 404 and in compliance with GLP, three New Zealand White rabbits were dermally exposed to 0.5 g of ALUM-17 as a powder (analytical purity of min. ) moistened with distilled water (0.5 mL) under a semi-occlusive dressing for 4 h. After removal of the residual test item, skin irritation was scored by the method of Draize (1959) at 24, 48 and 72 h after exposure.
No skin responses were noted during the study. All treated skin sites appeared normal at the 24 h observation. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0, 0, 0 for erythema and 0, 0, 0 for oedema score, respectively. In this study, ALUM-17 is therefore not a skin irritant on rabbits.
Under the test conditions, Aluminium sulphate is not classified as irritating to skin according to the Regulation (EC) N° 1272-2008 (CLP) and the GHS.
