  • Health Effects: Exposure to high amount of cobalt can cause heart, lung, kidney, and liver damage. Skin contact is known to result in contact dermatitis. Cobalt may also have mutagenic and carcinogenic effects. (L29, L30) Source: Toxin and Toxin Target Database (T3DB)
  • Toxicity Summary: IDENTIFICATION: Cobalt sulfate is a red powder. It is used in storage batteries; in cobalt-electroplating baths; as drier for lithographic inks, and varnishes; in ceramics, enamels, and glazes to prevent discoloring; in cobalt pigments for decorating porcelain. HUMAN EXPOSURE AND TOXICITY: Cardiomyopathy has been observed in individuals who consume large quantities of beer where cobalt sulfate was added as a foam stabilizer. Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the heart, thyroid and bone marrow, resulting in cardiomyopathy, goiter and polycythemia. ANIMAL STUDIES: Rats and mice exposed short term to cobalt sulfate by inhalation exhibited necrosis and inflammation of the respiratory tract epithelium. Rats developed thymus necrosis and testicular atrophy. Rats exposed for 2-3 months to cobalt sulfate in the diet for 24 weeks had significant reductions in heart enzyme activity levels. Rats and mice were exposed to cobalt sulfate heptahydrate by inhalation 6 hr/day, 5 days/week for 13 weeks developed adverse effects throughout the respiratory system.

  • Toxicity Summary: Cobalt is believed to exhibit its toxicity through a oxidant-based and free radical-based processes. It produces oxygen radicals and may be oxidized to ionic cobalt, causing increased lipid peroxidation, DNA damage, and inducing certain enzymes that lead to cell apoptosis. Cobalt has also been shown to block inorganic calcium channels, possibly impairing neurotransmission. Cobalt can also chelate lipoic acids, impairing oxidation of pyruvate or fatty acids. In addition, cobalt may inhibit DNA repair by interacting with zinc finger DNA repair proteins, and has also been shown to inhibit heme synthesis and glucose metabolism. Cobalt may activate specific helper T-lymphocyte cells and interact directly with immunologic proteins, such as antibodies (IgA and IgE) or Fc receptors, resulting in immunosensitization.

  • Environmental Fate: ATMOSPHERIC FATE: Inorganic cobalt compounds are nonvolatile and released into the atmosphere in particulate form(1). Particulate-phase cobalt compounds are removed from the air by wet and dry deposition(SRC). Cobalt has been detected in atmospheric deposition(2) and in rain-snow precipitation(3).

Questions this page answers

This official record identifies the substance as prohibited for cosmetic use in the stated market scope. Do not rely on a formulation containing this identity until the cited source, effective date and exact substance match have been verified.

A prohibition entry may contain no separate condition text because the regulatory outcome is the prohibition itself. The standards are separate controlled publications; absence from a locally indexed excerpt is not permission.
