?br>
Corrosive effect on skin and mucous membranes.
Irritant to skin and mucous membranes.
on the eye:
?br>
Strong corrosive effect.
Irritating effect.
Sensitization: No sensitizing effects known.
?br>
Subacute to chronic toxicity:
?br>
Animal studies have shown damage to the gastrointestinal system,
kidney, bladder, blood and respiratory tract from butyric acid
exposure. Convulsions have also been reported.
Subacute to chronic toxicity:
?br>
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.
Additional toxicological information:
?br>
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.
No classification data on carcinogenic properties of this material is
