ENVIRONMENTAL FATE AND BEHAVIOUR

Artificial pollution sources

Release to the environment of this substance can occur from industrial use: in the production of articles, in processing aids at industrial sites, as processing aid, as an intermediate step in further manufacturing of another substance (use of intermediates) and formulation of mixtures. Other release to the environment of this substance is likely to occur from: indoor use (e.g. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners) and outdoor use.
