Consumer Uses

This substance is used in the following products: washing & cleaning products, fertilisers, welding & soldering products, polishes and waxes, plant protection products and pH regulators and water treatment products.
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: 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).
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) and outdoor use in long-life materials with low release rate (e.g. metal, wooden and plastic construction and building materials).
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).
This substance can be found in products with material based on: metal (e.g. cutlery, pots, toys, jewellery), stone, plaster, cement, glass or ceramic (e.g. dishes, pots/pans, food storage containers, construction and isolation material) and plastic (e.g. food packaging and storage, toys, mobile phones).

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

Formulation or re-packing

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: formulation of mixtures, formulation in materials, as processing aid, in processing aids at industrial sites, as an intermediate step in further manufacturing of another substance (use of intermediates), in the production of articles and of substances in closed systems with minimal release.

Uses at industrial sites

This substance is used in the following products: pH regulators and water treatment products, coating products, polymers, laboratory chemicals, water treatment chemicals, lubricants and greases and washing & cleaning products.
This substance is used in the following areas: building & construction work and municipal supply (e.g. electricity, steam, gas, water) and sewage treatment.
This substance is used for the manufacture of: chemicals, food products, electrical, electronic and optical equipment, machinery and vehicles, plastic products and rubber products.
Release to the environment of this substance can occur from industrial use: as processing aid, in processing aids at industrial sites, in the production of articles and of substances in closed systems with minimal release.

Manufacture

Release to the environment of this substance can occur from industrial use: manufacturing of the substance, formulation of mixtures, formulation in materials, as an intermediate step in further manufacturing of another substance (use of intermediates) and as processing aid.
