Consumer Uses
ECHA has no public registered data indicating whether or in which chemical products the substance might be used.
Release to the environment of this substance can occur from industrial use:
manufacturing of the substance,
formulation of mixtures,
formulation in materials,
in processing aids at industrial sites,
in the production of articles,
as an intermediate step in further manufacturing of another substance (use of intermediates),
as processing aid and
of substances in closed systems with minimal release.
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
indoor use in close systems with minimal release (e.g. cooling liquids in refrigerators, oil-based electric heaters).
