Chemical Substances Search
Last updated 13 June 2013. Database contains 8 998 unique substances and contains information from 34 933 dossiers.
NB: The Tonnage band column contains aggregated total tonnage band values per joint / individual submission. These values are calculated from the non-confidential tonnage data of ALL registrants in a joint submission.
Chemical Property Search (via eChemPortal)
Information on chemical properties of registered substances is directly accessible via eChemPortal.
ECHA is a key collaborator in the development of eChemPortal software and hosting, working in cooperation with OECD and other international regulatory institutions.
As substances are registered under REACH, there is an obligation on registrants to provide information on the substances they manufacture or import. ECHA subsequently has the obligation to make certain of this information publicly available. Here you can find a variety of information on registered substances: for example their hazardous properties, their classification and labelling and how to use the substances safely.
Note that the amount of information provided can vary for different substances – information comes from companies' REACH registrations and the higher the production volume of the substance the more information companies need to provide. Please be aware that ECHA does not verify the information before dissemination.
The number of substances for which information is available in the database will increase over time as companies submit more registrations dossiers. For further information about the content of the database, please read the Questions and Answers.
Important Note on EC Numbers and List Numbers:
Some substances returned via the search above did not previously have an EC Number assigned, or were contained in a dossier for which a registrant did not indicate the existing assigned EC Number. These substances may have been assigned a List Number by ECHA.
|2xx-xxx-x||EINECS (European INventory of Existing Commercial chemical Substances) List||Official|
|3xx-xxx-x||EINECS (European INventory of Existing Commercial chemical Substances) List||Official|
|4xx-xxx-x||ELINCS (European LIst of Notified Chemical Substances) List||Official|
|5xx-xxx-x||NLP (No-Longer Polymers) List||Official|
|6xx-xxx-x||Automatically assigned to substances identified only with a CAS No.||Not Official|
|7xx-xxx-x||Assigned manually to validated substances from inquiries by ECHA||Not Official|
|8xx-xxx-x||Automatically assigned to substances identified only with a CAS No. (continuation of the 6xx-xxx-x series)||Not Official|
|9xx-xxx-x||Automatically assigned to substances without a CAS No. or other numerical identifier||Not Official|
Note: Authorities and companies should be aware that List Numbers do not have any legal significance; rather they are purely technical identifiers for processing a submission via REACH-IT.
List Numbers should not be used in Safety Data Sheets, or for any similar documents.
