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 has not been registered under the REACH Regulation, therefore as yet ECHA has not received any data about this substance from registration dossiers.

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 in the following products: polymers.

Other release to the environment of this substance is likely to occur from: 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 activities or processes at workplace: the low energy manipulation of substances bound in materials or articles.

Release to the environment of this substance can occur from industrial use: 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: outdoor use in long-life materials with low release rate (e.g. metal, wooden and plastic construction and building materials) and 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).

This substance can be found in products with material based on: plastic (e.g. food packaging and storage, toys, mobile phones).

This substance is used in the following products: polymers.

This substance is used for the manufacture of: plastic products and machinery and vehicles.

This substance is used in the following activities or processes at workplace: non-industrial spraying, treatment of articles by dipping and pouring, production of mixtures or articles by tabletting, compression, extrusion or pelletisation and the low energy manipulation of substances bound in materials or articles.

Other release to the environment of this substance is likely to occur from: indoor use.

This substance is used in the following products: polymers.

This substance is used in the following activities or processes at workplace: transfer of chemicals, closed processes with no likelihood of exposure, closed, continuous processes with occasional controlled exposure, closed batch processing in synthesis or formulation, batch processing in synthesis or formulation with opportunity for exposure, mixing in open batch processes, transfer of substance into small containers and laboratory work.

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

This substance is used in the following products: polymers.

This substance is used for the manufacture of: plastic products and rubber products.

This substance is used in the following activities or processes at workplace: transfer of chemicals, batch processing in synthesis or formulation with opportunity for exposure, production of mixtures or articles by tabletting, compression, extrusion or pelletisation, the low energy manipulation of substances bound in materials or articles and mixing in open batch processes.

Release to the environment of this substance can occur from industrial use: in the production of articles and as processing aid.

This substance is used in the following activities or processes at workplace: transfer of chemicals, closed processes with no likelihood of exposure, closed, continuous processes with occasional controlled exposure, closed batch processing in synthesis or formulation, batch processing in synthesis or formulation with opportunity for exposure, transfer of substance into small containers and laboratory work.

Release to the environment of this substance can occur from industrial use: manufacturing of the substance.

Precautions for using this substance have been recommended by its registrants under REACH, as follows:

Prevention statements

When handling this substance: wear protective gloves and/or clothing, and eye and/or face protection as specified by manufacturer/supplier.

Response statements

In case of incident: If in eyes: rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do – continue rinsing. Rinse the mouth. If eye irritation persists get medical advice/attention. If swallowed: call a poison center or doctor/physician if you feel unwell.
