- Executive summary:
An acute skin irritation/corrosion study in New Zealand White rabbits was performed in accordance with OECD Guideline 404. Three New Zealand White rabbits were treated topically on each of two test sites which were previously clipped free of hair. 0.5 g of lithium carbonate Technical Grade was placed in contact with each test site. The test sites were covered with gauze patches and the trunk of each animal was wrapped with a sheet of cheesecloth. The test material was in contact with the skin for 4 hours, after which the animals were unwrapped and the test material removed. Approximately 30 minutes, 24, 48, 72 hours after the end of the exposure period, the test sites were scored for irritation using the method of Draize. Irritation observed in one of the three animals (scored 1 for erythema) had resolved by the end of the study (day 5). Under the conditions of this study, the test material is not irritating to intact skin of New Zealand White rabbits when brought into contact with the skin for four hours. The used scores of the test system (US scheme) were adapted to the EU scheme. Thus, based on the results obtained lithium carbonate has not to be classified and labelled according to Regulation (EC) No 1272/2008 (CLP).

One hour after dosing, unwashed eyes had mild corneal opacities, iritis, moderate conjunctivitis and white and hemorrhagic areas on the conjunctivae. Washed eyes had slight corneal opacities and slight conjunctivitis. At the 24-hour scoring, both washed and unwashed eyes had mild corneal opacities and moderate conjunctivitis. Irritation gradually resolved; washed eyes recovered by day 4, and unwashed eyes recovered by day 7. Washing the eyes with tap water shortly after exposure decreased both the severity and duration of the irritation observed. - Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- Under the conditions of this study, the test material is irritating to eyes.
- Executive summary:
An acute eye irritation/corrosion study in New Zealand White rabbits was performed in accordance with OECD Guideline 405. Lithium carbonate Technical Grade was instilled into the test eyes of 4 New Zealand White rabbits at a dose of 0.1 g. The eyes of two rabbits remained unwashed while the eyes of the remaining two rabbits were gently washed with 100 mililitres of tap water approximately 20 - 30 seconds after treatment. Eyes were assessed for irritation using the method of Draize at 1, 24, 48 and 72 hours after installation, as well as on days 4 and 7. Slight to mild corneal opacities, iritis and slight to moderate conjunctivitis were noted in all eyes. Unwashed eyes also had hemorrhages and white areas on the conjunctivae. Washing the eyes with tap water shortly after exposure decreased both the severity and the duration of the irritation observed. Irritation gradually resolved; washed eyes recovered by day 4 and unwashed eyes recovered by day 7. Based on the results obtained with unwashed eyes, lithium carbonate has to be classified and labelled as Cat.2 (H319) in respect to eye irritation according to the Regulation (EC) No 1272/2008 (CLP).

Additional information
Skin:
An acute skin irritation/corrosion study in New Zealand White rabbits was performed in accordance with OECD Guideline 404. Three New Zealand White rabbits were treated topically on each of two test sites which were previously clipped free of hair. 0.5 g of lithium carbonate technical Grade was placed in contact with each test site. The test sites were covered with gauze patches and the trunk of each animal was wrapped with a sheet of cheesecloth. The test material was in contact with the skin for 4 hours, after which the animals were unwrapped and the test material removed. Approximately 30 minutes, 24, 48, 72 hours after the end of the exposure period, the test sites were scored for irritation using the method of Draize. Irritation observed in one of the three animals (scored 1 for erythema) had resolved by the end of the study (day 5). Under the conditions of this study, the test material is not irritating to intact skin of New Zealand White rabbits when brought into contact with the skin for four hours. The used scores of the test system (US scheme) were adapted to the EU scheme. Thus, based on the results obtained lithium carbonate has not to be classified and labelled according to Regulation (EC) No 1272/2008 (CLP).

Justification for classification or non-classification
Classification, Labelling, and Packaging
Regulation (EC) No 1272/2008
The available experimental test
data are reliable and suitable for classification purposes under
Regulation (EC) No 1272/2008. Based on available data on skin and eye
irritation/corrosion, the test item is not to be considered irritating
to the skin but irritating to the eyes. In conclusion, lithium carbonate
is not classified according to Regulation (EC) No 1272/2008 (CLP) with
regard to skin irritation. With respect to eye irritation, lithium
carbonate has to be classified into cat. 2 (H319) according to the
Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in
Regulation (EU) No 2017/776.
