Dissemination platform updates

Dissemination Platform 4.6.5 (9 March 2021)

The EU Chemicals Legislation Finder (EUCLEF) has expanded its scope, giving now the overview of 56 pieces of EU’s legislation on chemicals. 16 new pieces of legislation have been added, as follows:


For each of the 56 pieces of legislation covered by EUCLEF a legislation profile can be found on the ECHA website, along with links to the correspondent lists of substances.

EUCLEF is free of charge and fully integrated with the Search for chemicals on ECHA’s website.

EUCLEF is funded by the EU Programme for Competitiveness of Enterprises and Small and Medium-sized Enterprises (COSME).

Dissemination Platform v4.6.0 (21 December 2020)
REACH Registered substances

The REACH registered substance factsheets have been updated as follows:

  • The General Information landing page has now been split into two sub-pages:
    • Substance Identity and
    • Administrative Information
  • Non-confidential “other” identifiers provided, such as Trade names, Common names, Synonyms, Index numbers etc. are now distinguished and visible in the Substance Identity page.
  • The Substance Compositions section has been improved, and non-confidential compositions are now distinguished by their type – Boundary compositions provided to cover an entire joint submission, specific Legal entity compositions for each registrant, and so on.
  • Composition blocks have been improved and now explicitly indicate with text and an icon whether a given composition contains an impurity or additive relevant for C&L, or relates to a nanomaterial form of the substance.
  • Scientific Endpoint study record test materials are now properly displayed, where provided and not confidential. Test materials are now presented similarly to a composition block, with (where relevant) constituents, impurities, and additives.
  • Cross links between factsheet sections have been improved where provided.


Dissemination Platform v4.5.0 (9 November 2020)


REACH Registered substances

The REACH registered substance portal has been updated as follows:

  • IUCLID 6.5 dossier format is now supported, so such dossiers can be processed and published.
  • Total tonnage band and registration status calculation and presentation has been improved.
  • These improvements are also integrated to the substance Infocards.
  • Registrants and suppliers details are presented in a new data view, increasing transparency.
C&L Inventory

Aligning with identified quick wins from the full C&L Inventory redesign project, the current C&L Inventory portal has been improved as follows:

  • The portal results table now shows either 1) the harmonised classification, where available (or the fact that there are multiple possible harmonised classifications), 2) the first ranked notified classification coming from REACH registrations, where present, or 3) the first ranked notified classification coming from CLP notifications.
  • The presented classification is available for export, up to the permitted maximum number of exportable rows.
  • The C&L regulatory context has been split, so that it is now explicitly visible per substance whether that substance has a harmonised C&L, is subject to Seveso, or has notified C&L data.
  • This improved visibility of regulatory context is also integrated to the substance Infocards, and to the Advanced search for substances.
POPs Regulation
  • Key datasets from the POPs Regulation have been integrated to the Dissemination Platform – the list of identified POPs substances, and the list of substances proposed as POPs
  • A Persistent Organic Pollutant (POP) Property of concern has been added, integrated to the substance Infocards, and to the Advanced search for substances.
Biocides Data
  • Annex I active substance redirection to authorised products fixed.
  • Regulatory process search filters updated.
  • Publication mechanism issue resolved.
Other changes
  • ECHA substance identity management system upgrade support.
  • Login and security upgrade support.
  • Back end improvements and small bug fixes.


Dissemination Platform v4.3.0 (4 December 2019)
Search Enhancements
  • Simple search
    • Now possible to search by any public identifier of any type, including names, translated names, numbers, codes, index numbers etc.
    • Other minor improvements to allow searches with 2 characters or special characters from any EU language.
List portal searches
  • Aligned with the above, it is now possible to search in every Dissemination Platform integrated list using any public identifier of any type.
  • Where available the beta list APIs have been slightly modified to reflect the new search possibilities.
Properties of Concern
  • The wording of the properties of concern text has been slightly improved in the Infocard display, to make clear the degree of certainty of the concern, where applicable. The corresponding search options have been updated in the Advanced search.
Brief Profile
  • Properties of Concern – the updated properties of concern data from the Infocards is now available in the Brief Profiles.
  • Nanomaterial form – the new nanomaterial form data from Infocards is now available in the Brief Profiles.
  • Substance identifiers section – the improved substance identifiers section from Infocards is now available in the Brief Profiles, showing translated names where available, and all other public identifiers for substances.
REACH Registration adaptation to IUCLID 6.4
  • The Dissemination Platform has been upgraded to handle data in the IUCLID 6.4 format. Daily publication will resume, and as soon as possible all the data submitted in this format over the past months will be processed and published.
  • The corresponding changes related to the updated IUCLID format have been taken into account where relevant in the substance Infocards, Brief Profiles, and REACH registered substance factsheets.
  • All Nanomaterial endpoint study data will be published, if provided and where not claimed confidential. This data will also be included in the Brief Profiles, where available.
Other small improvements
  • Behind the scenes fixes to improve C&L data synchronisation between REACH registered substance factsheets, the C&L Inventory, substance Infocards, and Brief Profiles.
  • Biocide document publication improvements.
  • Biocide datasets handling improved for cancelled or expired assets.
