Conclusion on classification

Dibutylphthalate is classified:

  • in Annex I of Directive 67/548/EEC: N; R50 Very toxic to aquatic organisms.
  • in Annex VI of REGULATION (EC) No 1272/2008 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL:

    Aquatic. Acute 1, H400: Very toxic to aquatic life.

According to the CLP Regulation, the substance is also classified for hazardous to the aquatic environment as:

Chronic 2, H411: Toxic to aquatic life with long lasting effects (as DBP is rapidly degradable substance with chronic NOEC (for crustacea and fish) > 0,01 to ≤ 0,1 mg/L)
