    Sodium ethyl xanthate - Home - NICNAS

    Sodium ethyl xanthate is poisonous but there is a lack of information about its health effects. Sodium ethyl xanthate is readily absorbed by the skin and is a skin and eye irritant. Animal studies on other xanthates show that repeated exposure to sodium ethyl xanthate may cause damage to the central nervous system, liver and kidneys.
