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
ECHA has no public registered data indicating whether or in which chemical products the substance might be used.
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).
Article service life
Release to the environment of this substance can occur from industrial use:
industrial abrasion processing with high release rate (e.g. sanding operations or paint stripping by shot-blasting),
industrial abrasion processing with low release rate (e.g. cutting of textile, cutting, machining or grinding of metal) and
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) 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 products with material based on:
plastic (e.g. food packaging and storage, toys, mobile phones) and
paper (e.g. tissues, feminine hygiene products, nappies, books, magazines, wallpaper).
