Conclusion on classification

The classification of the butylene oligomers is based upon the available experimental data for member streams. Four toxicity studies are available for acute invertebrate, algal and fish toxicity for the streams 97280-83-6 and 9003-29-6. The reported effect concentrations were based on WAF data and the ranged from >1.55 - >100mg/l WAF. Based on these effect concentrations members of this category would be not be classified under the DSD and CLP Regulations.
