Justification for classification or non-classification

The registered UVCB substance Reaction products of 3-methylbutanal and 3-methylbut-3-en-1-ol, distillation overheads, acid-treated, hydrogenated contains a constituent which was classified as skin sensitizer according to Directive 67/548/EEC and Regulation (EC) No 1272/2008:

  • Isovaleraldehyde (0-20%, CAS 590-86-3):skin sensitizer(R 43, Sens Cat 1)

Therefore, a classification

  • with R41 according to Directive 1999/45/EG
  • and with Skin Sens Category 1 according to Regulation (EC) No 1272/2008
is proposed for the registered UVCB substance Reaction products of 3-methylbutanal and 3-methylbut-3-en-1-ol, distillation overheads, acid-treated, hydrogenated.
