Additional information

Members of this category are gases and are extremely unlikely to reside in the aquatic or terrestrial compartment. Deriving an aquatic or soil PNEC for a gas is unreasonable and technically of little use for risk assessment as the substance will not be present in the aquatic or terrestrial environment.

Conclusion on classification

The members of the category, 68955-28-2, 87741-01-3 and 92045-23-3 are listed in Annex I but are not classified for environmental hazards. Additionally the major constituent component- 1, 3 butadiene is also listed but not classified for environmental hazards. The category C4 high 1,3,- butadiene (>0.1%) would not be classified for environmental hazards.
