    Chronic Effects on Humans Not available.
    Other Toxic Effects on
    Slightly hazardous in case of skin contact (irritant), of ingestion, of inhalation (lung irritant).
    Humans
    Special Remarks on        Not available.    
    Toxicity to Animals
    Special Remarks on        Not available.    
    Chronic Effects on Humans
    Special Remarks on other        Acute Potential Health Effects:    
    Toxic Effects on Humans        Skin: May cause skin irritation.    
    Eyes: May cause eye irritation.
    Inhalation: May cause respiratory tract irritation.
    Ingestion: May cause gastrointestinal tract irritation. Magnesium salts are absorbed very slowly. Oral
    administration causes nothing more than purging and is not likely to produce serious toxic effects. However,
    some compounds may cause hypermagnesemia in individuals with serverely impaired renal function which may
    affect behavior/central nervous system and respiratory system. Symptoms of hypermagnesinia poisoning may
    include central nervous system depression, lethargy, coma, circulatory failure, and respiratory arrest due to
    neuromuscular blockade(respiratory paralysis).
    The toxicological properties of this substance have not been fully investigated.
