Additional information

Carcinogenic potential of the main constituent 3-methylbut-3-en-1-ol (CAS 763 -32 -6).

No carcinogenicity data are available for 3-methylbut-3 -en-1-ol (Isoprenol).

 

Carcinogenic potential of the impurity formaldehyde (CAS 50-00-0).

The impurity formaldehyde is found to be present at concentrations up to 0.999% in the substance to be registered (3-methylbut-3 -en-1-ol; Isoprenol)).

Formaldehyde is listed in Annex VI to the CLP Regulation with the harmonized classification as a carcinogen Cat.1B (H350: May cause cancer).

Accordingly, the registered substance (3-methylbut-3 -en-1-ol or Isoprenol) needs to be classified as a carcinogen Cat.1B (H350: May cause cancer) due to the impurity formaldehyde.

For the alternative grade (without relevant levels of the impurity formaldehyde), no data are available warranting a classification of the registered substance (3-methylbut-3 -en-1-ol or Isoprenol) as a carcinogen.

Justification for classification or non-classification

The presence of the impurity formaldehyde (up to 0.999%) triggers a classification for the registered substance as a carcinogen Cat 1B (H350: May cause cancer).
