Additional information
No acute oral, dermal and inhalation toxicity data are available for 3-butyn-1-ol. Only one mouse LD50 intravenous of 100 mg/kg is available; however, this information is inconclusive for the classification of the substance for acute toxicity.
Justification for classification or non-classification
Available information is inconclusive for the classification of the substance. Acute toxicity by intravenous route can not be used for the classification of 3-Butyn-1-ol.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
