11 Toxicological information
Acute toxicity:
Primary irritant effect:
on the skin: Irritant to skin and mucous membranes.
on the eye: Irritating effect.
Sensitization: No sensitizing effects known.
Other information (about experimental toxicology):
Tumorigenic effects have been observed on tests with laboratory animals.
Reproductive effects have been observed on tests with laboratory animals.
Carcinogenic effects have been observed on tests with laboratory animals.
Subacute to chronic toxicity:
Prolonged inhalation of silica may cause silicosis, the formation of
adhesions in the lungs progressing to the formation of a continuous mass
of fibrous tissue. If the disease continues, death may occur.
Tuberculosis is often found in people with silicosis. Some forms of
silica are more fibrogenic than others. Some forms of crystalline silica
have shown carcinogenic, tumorigenic and neoplastic effects in laboratory
animals. Amorphous silica is less harmful by inhalation than crystalline
forms. Amorphous silica may, however, contain small amounts of
crystalline silica.
Additional toxicological information:
To the best of our knowledge the acute and chronic toxicity of this
substance is not fully known.
The Registry of Toxic Effects of Chemical Substances (RTECS) contains
tumorigenic and/or carcinogenic and/or neoplastic data for components in
this product.
IARC-1: Carcinogenic to humans: sufficient evidence of carcinogenicity.
NTP-2: Reasonably anticipated to be a carcinogen: limited evidence from
studies in humans or sufficient evidence from studies in experimental
animals.
