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 ≥ 10 to < 100 tonnes per annum.

This substance is used in articles, by professional workers (widespread uses), in formulation or re-packing 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: potentially closed industrial processing with minerals/metals at elevated temperature (e.g. smelters, furnaces, refineries, coke ovens), open transfer and processing with minerals/metals at elevated temperature, high energy work-up of substances bound in materials or articles (e.g. hot rolling/forming, grinding, mechanical cutting, drilling or sanding), hot work operations with metals (e.g. welding, soldering, gouging, brazing, flame cutting) and production of mixtures or articles by tabletting, compression, extrusion or pelletisation.

Release to the environment of this substance can occur from industrial use: industrial abrasion processing with low release rate (e.g. cutting of textile, cutting, machining or grinding of metal) and industrial abrasion processing with high release rate (e.g. sanding operations or paint stripping by shot-blasting).

This substance can be found in complex articles, with no release intended: vehicles and machinery, mechanical appliances and electrical/electronic products (e.g. computers, cameras, lamps, refrigerators, washing machines). This substance can be found in products with material based on: metal (e.g. cutlery, pots, toys, jewellery).

This substance is used in the following products: polymers.

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, mixing in open batch processes, calendering operations, transfer of substance into small containers, roller or brushing applications and blowing agents in manufacture of foam.

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), outdoor use, 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).

This substance is used in the following products: metals and metal surface treatment products.

This substance is used in the following activities or processes at workplace: potentially closed industrial processing with minerals/metals at elevated temperature (e.g. smelters, furnaces, refineries, coke ovens), high energy work-up of substances bound in materials or articles (e.g. hot rolling/forming, grinding, mechanical cutting, drilling or sanding), closed, continuous processes with occasional controlled exposure, open transfer and processing with minerals/metals at elevated temperature, handling of solid inorganic substances (e.g. ores and raw metal oxides, packaging/mixing/blending and weighing of metal powders), closed processes with no likelihood of exposure, hot work operations with metals (e.g. welding, soldering, gouging, brazing, flame cutting), production of metal powders (hot processes) and production of metal powders (wet processes).

Release to the environment of this substance can occur from industrial use: formulation in materials and formulation of mixtures.

This substance is used in the following products: metals, metal surface treatment products and polymers.

This substance is used for the manufacture of: electrical, electronic and optical equipment, metals, fabricated metal products and machinery and vehicles.
