Brief Profile

Diss Brief Profile

The Brief Profile summarizes the non-confidential data on substances as it is held in the databases of the European Chemicals Agency (ECHA), including data provided by third parties. The Brief Profile is automatically generated; note that it does not currently distinguish between harmonised classification and minimum classification; information requirements under different legislative frameworks may therefore not be fully up to date or complete. For accuracy reasons, substance manufacturers and imports have the responsibility to consult official sources, e.g. the electronic edition of the Official Journal of the European Union.
This Brief Profile is covered by the ECHA Legal Notice.

About this substance

This substance is registered under the REACH Regulation and is manufactured in and / or imported to the European Economic Area, at ≥ 1 to < 10 per annum.

This substance is used in articles, by professional workers (widespread uses) and at industrial sites.

ECHA has no public registered data indicating whether or in which chemical products the substance might be used.

ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment.

This substance is used in the following activities or processes at workplace: closed, continuous processes with occasional controlled exposure, transfer of chemicals at non-dedicated facilities, transfer of substance into small containers, heat / pressure transfer fluids in closed systems and manual maintenance (cleaning and repair) of machinery.

Release to the environment of this substance can occur from industrial use: of articles where the substances are not intended to be released and where the conditions of use do not promote release. Other release to the environment of this substance is likely to occur from: indoor use in long-life materials with low release rate (e.g. flooring, furniture, toys, construction materials, curtains, foot-wear, leather products, paper and cardboard products, electronic equipment).

This substance can be found in complex articles, with no release intended: machinery, mechanical appliances and electrical/electronic products (e.g. computers, cameras, lamps, refrigerators, washing machines).

ECHA has no public registered data indicating whether or in which chemical products the substance might be used.

ECHA has no public registered data on the types of manufacture using this substance.

This substance is used in the following activities or processes at workplace: closed processes with no likelihood of exposure, closed, continuous processes with occasional controlled exposure, closed batch processing in synthesis or formulation, transfer of chemicals at non-dedicated facilities, transfer of substance into small containers, heat / pressure transfer fluids in closed systems and manual maintenance (cleaning and repair) of machinery.

Other release to the environment of this substance is likely to occur from: indoor use in close systems with minimal release (e.g. cooling liquids in refrigerators, oil-based electric heaters) and outdoor use in close systems with minimal release (e.g. hydraulic liquids in automotive suspension, lubricants in motor oil and break fluids).

ECHA has no public registered data indicating whether or in which chemical products the substance might be used.

ECHA has no public registered data on the use of this substance in activities or processes at the workplace.

ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment.

ECHA has no public registered data indicating whether or in which chemical products the substance might be used.

ECHA has no public registered data on the types of manufacture using this substance.

This substance is used in the following activities or processes at workplace: transfer of chemicals, closed processes with no likelihood of exposure, closed, continuous processes with occasional controlled exposure, batch processing in synthesis or formulation with opportunity for exposure, transfer of substance into small containers, laboratory work, heat / pressure transfer fluids in closed systems and manual maintenance (cleaning and repair) of machinery.

Release to the environment of this substance can occur from industrial use: of substances in closed systems with minimal release.

ECHA has no public registered data on the use of this substance in activities or processes at the workplace.
