Danger! According to the harmonised classification and labelling (CLP00) approved by the European Union, this substance causes severe skin burns and eye damage and may cause respiratory irritation.

Additionally, the classification provided by companies to ECHA in REACH registrations identifies that this substance causes serious eye damage and may be corrosive to metals.

This substance is manufactured and/or imported in the European Economic Area in 10 000 - 100 000 tonnes per year.

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

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: washing & cleaning products, cosmetics and personal care products, adhesives and sealants, air care products, biocides (e.g. disinfectants, pest control products), coating products, finger paints, non-metal-surface treatment products and polishes and waxes.
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

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), outdoor use in long-life materials with low release rate (e.g. metal, wooden and plastic construction and building materials), outdoor use in long-life materials with high release rate (e.g. tyres, treated wooden products, treated textile and fabric, brake pads in trucks or cars, sanding of buildings (bridges, facades) or vehicles (ships)) and indoor use in long-life materials with high release rate (e.g. release from fabrics, textiles during washing, removal of indoor paints).
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: stone, plaster, cement, glass or ceramic (e.g. dishes, pots/pans, food storage containers, construction and isolation material), fabrics, textiles and apparel (e.g. clothing, mattress, curtains or carpets, textile toys) and leather (e.g. gloves, shoes, purses, furniture).
This substance is intended to be released from scented: clothes.
