11 Toxicological information
Acute toxicity:
Primary irritant effect:
on the skin:
Corrosive effect on skin and mucous membranes.
Irritant to skin and mucous membranes.
on the eye:
Strong corrosive effect.
Irritating effect.
Sensitization: No sensitizing effects known.
Subacute to chronic toxicity:
Corrosive materials are acutely destructive to the respiratory tract,
eyes, skin and digestive tract. Eye contact may result in permanent
damage and complete vision loss. Inhalation may result in respiratory
effects such as inflammation, edema, and chemical pneumonitis. May cause
coughing, wheezing, laryngitis, shortness of breath, headache, nausea and
vomiting. Ingestion may cause damage to the mouth, throat and esophagus.
May cause skin burns or irritation depending on the severity of the
exposure.
Organic silicon compounds are generally of low toxicity. Those
exhibiting moisture sensitivity may be strongly irritating or corrosive
on contact.
Additional toxicological information:
Swallowing will lead to a strong corrosive effect on mouth and throat and
to the danger of perforation of esophagus and stomach.
To the best of our knowledge the acute and chronic toxicity of this
substance is not fully known.
