TOXICOLOGICAL INFORMATION
Mica:
Oral LD50 (Rat) >2000 mg/kg
Amorphous Silica:
Oral LD50 (Rat) >5000 mg/kg
Dermal LD50 (Rabbit) >2000mg/kg
Clay:
Oral LD50 (Rat) >5000 mg/kg
Dermal LD50 (Rabbit) >5000mg/kg
Nitrogen
Simple asphyxiant
Carbon Dioxide
Simple asphyxiant
LCLo (inhalation in humans): 90,000ppm/ 5 minutes.
Specific Target Organ Toxicity (STOT) – single exposure
Sodium Bicarbonate: Available data indicates this component is not expected to cause target organ
effects after a single exposure.
Calcium Carbonate: Available data indicates this component is not expected to cause target organ effects
after a single exposure.
Nitrogen: Exposure to nitrogen gas at high concentrations can cause suffocation by reducing oxygen
available for breathing. Breathing very high concentrations can cause dizziness, shortness of breath,
unconsciousness or asphyxiation.
Specific Target Organ Toxicity (STOT) – repeat exposure
Sodium Bicarbonate: Available data indicates this component is not expected to cause target organ
effects after repeat exposure.
Calcium Carbonate: Available data indicates this component is not expected to cause target organ effects
after repeat exposure.
Serious Eye damage/Irritation
Sodium Bicarbonate: Slightly irritating (rabbit)
Calcium Carbonate: Not irritating (rabbit)
Mica: Not irritating (rabbit)
Skin Corrosion/Irritation
Sodium Bicarbonate: Slightly irritating (rabbit)
Calcium Carbonate: Not irritating (rabbit)
Mica: Not irritating (rabbit)
Respiratory or Skin Sensitization
Calcium Carbonate: Non-sensitizing to skin in Mouse local lymph node assay.
Carcinogenicity
Calcium carbonate and mica may contain small quantities of quartz (crystalline silica) as an impurity.
Prolonged exposure to respirable crystalline silica dust at concentrations exceeding the occupational
exposure limits may increase the risk of developing a disabling lung disease known as silicosis. IARC has
classified Silica Dust, Crystalline, in the form of quartz or cristobalite as 1 (carcinogenic to humans).
Germ Cell Mutagenicity
Sodium Bicarbonate: Negative test results in animal studies.
Calcium Carbonate: Negative results in the Mammalian Cell Gene Mutation Assay with and without
metabolic activation, Ames test, and In vitro Mammalian Chromosome Aberration Test.
