Description of key information
Based on the result of the eye irritation study with lithium chloride, the test substance is to be considered irritating. Based on the result of the skin irritation study with lithium chloride, the test substance is to be considered not irritating to skin. Although the animal data would not require classification with regard to skin irritation, based on experiences with lithium chloride in humans at production sites the substance is classified as skin irritant.

- 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 chloride anhydrous 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 after the end of the exposure period, the test sites were scored for irritation using the method of Draize. The test sites were scored daily thereafter for 14 days.
Mild to moderate erythema and slight edema were noted on the test sites 4.5 hours post-dosing. Two rabbits had complete recovery on the test sites within 72-hours, at which time the third rabbit had developed eschar on one test site. Eschar persisted on this animal through day 14 of the study.
Although the animal data would not require classification with regard to skin irritation, based on experiences with lithium chloride in humans at production sites, the substance is classified as skin irritant.

- Executive summary:
An acute eye irritation/corrosion study in New Zealand White rabbits was performed in accordance with OECD Guideline 405. Lithium Chloride Anhydrous Technical 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 mL 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, 7, 10, 13 and 16.
Slight to mild corneal opacities, iritis and moderate to severe conjunctivitis was noted in both washed and unwashed eyes during the study. White, brown and hemorrhagic areas were noted on the conjunctivae of two rabbits. Irritation was greatest 1 -hour after dosing, then gradually subsided. Washed eyes recovered by day 7, and unwashed eyes recovered by day 16. Washing the eyes with tap water shortly after exposure decreased the duration of the irritation observed.
The used scores of the US scheme were adapted to the EU scheme.

Justification for classification or non-classification
The scores of the test system (US scheme) were adapted to the EU scheme. Based on the results obtained, lithium chloride has to be classified and labelled into Cat. 2 (H319) in respect to eye irritation according to the Regulation (EC) No 1272/2008 (CLP).
Although the animal data would not require classification with regard to skin irritation, based on experiences with Lithium chloride in humans at production sites the substance is classified as skin irritant: Cat. 2 (H315) according to the Regulation (EC) No 1272/2008 (CLP).
