Conclusion on classification

The substance, C-4000, should not be classified for environmental concerns within the GHS Hazard Categories.  The EU has adopted a version of the GHS that is specific to their needs so the assessment specific to the EU is that C-4000 is not classified according to regulation CLP 1272/2008.  No signal word or hazard statement is necessary.  This non-classification is based on the lack of acute toxicity in three sentinel aquatic species, minimal acute toxicity in one sentinel terrestrial invertebrate species, no acute toxicity in one sentinel mammalian vertebrate species, and lack of respiratory inhibition in a microbial sludge inoculum.
