Conclusion on classification
A harmonized classification towards environmental hazard was
adopted for octanoic acid. According to the regulation (EC) No
1272/2008, Annex VI, Table 3.1 the substance is classified as hazardous
to the aquatic environment, aquatic chronic 3: harmful to aquatic life
with long lasting effects (H412). This corresponds with the available
data presented in this dossier, a further self classification is not
