This substance is used by consumers, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing.

Consumer Uses

This substance is used in the following products: metals, welding & soldering products, metal surface treatment products and laboratory chemicals.
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.

Article service life

Release to the environment of this substance can occur from industrial use: in the production of articles, formulation in materials, formulation of mixtures, as an intermediate step in further manufacturing of another substance (use of intermediates), industrial abrasion processing with low release rate (e.g. cutting of textile, cutting, machining or grinding of metal) and in processing aids at industrial sites.
Other release to the environment of this substance is likely to occur from: outdoor use in long-life materials with low release rate (e.g. metal, wooden and plastic construction and building materials) and indoor use (e.g. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners).
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) and vehicles.
This substance can be found in products with material based on: metal (e.g. cutlery, pots, toys, jewellery).

Widespread uses by professional workers
