Additional information
Skin irritation
Aluminium metaphosphate was tested for induction of skin irritation in rabbits (strain: Zika) according to OECD Guideline 404 and in compliance with GLP (Prietzsch, 2014). The test animals (1 in the initial test, 2 in the confirmatory test) were dermally exposed to 0.5 g of the test material (moistened with 500 µL water) for 4 h. Skin reactions were evaluated immediately (first animal), 1, 24, 48 and 72 h after patch removal. No skin reactions were observed in any animal at any reading time point. The study was therefore terminated on Day 4. No further local or systemic effects were noted and there were no abnormalities in body weight development. The individual mean values for erythema/eschar and edema from gradings at 24, 48 and 72 h were 0 in all three animals.
Therefore, the test material does not fulfil the criteria for classification according to Regulation (EC) No 1272/2008 (CLP) and the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), and is thus considered to be not skin irritating.
Eye irritation
The eye irritating potential of aluminium metaphosphate was evaluated in rabbits (strain: Zika) in a GLP-study performed in accordance with OECD Guideline 405 (Prietzsch, 2014). The test material (100 mg) was applied into the conjunctival sac of one eye of each animal, the other eye serving as control. The test material (solid powder) was removed from the treated eyes at 1 h post-instillation by rinsing with physiological saline. Ocular reactions were examined and scored at 1, 24, 48, 72 and 96 h post-instillation. No effects on the iris were observed in any animal at any time point. At the 1 h reading, slight corneal opacity was noted in 1 animal and slight chemosis in all 3 animals, which had both fully reversed at the 24 h reading. Moderate conjunctival redness was observed in all animals at the 1 h reading. Conjunctival redness decreased to slight but persisted in all animals up to the 72 h reading. At 96 h post-instillation, all treated eyes had fully reversed to normal. No further local or systemic effects were noted and there were no abnormalities in body weight development up to the end of the observation period (14 days for the animal in the initial test, 5 days for the 2 animals in the confirmatory test). The individual mean values from gradings at 24, 48 and 72 h were 0 for corneal opacity, iritis and chemosis in all 3 animals, and 1.3/1.0/1.0 for conjunctival redness in each animal, respectively. The observed effects were fully reversible within 96 h post-instillation.
Therefore, the test material does not fulfil the criteria for classification according to Regulation (EC) No 1272/2008 (CLP) and the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), and is thus considered to be not eye irritating.
Justification for classification or non-classification
The available data indicate that the substance does not meet the classification criteria in accordance with Regulation (EC) No 1272/2008 (CLP) and the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
