Substance Information

NB: Registration status and tonnage

  • The REACH Registered substance portal was updated on 9th November 2020; the REACH registered factsheets were further updated on 21st December 2020. Details of the improvements can be found at Dissemination Platform Updates. Reprocessing the entire dataset is ongoing since 21 December 2020. ECHA is making all possible efforts to synchronise the registration status and tonnage with the shortest delay.
  • While reprocessing is ongoing please note that substances whose registration dossiers are not yet processed can incorrectly state in the Infocard that they are not registered under REACH. In these cases if there is a link to a REACH registered substance factsheet then the substance IS registered. The correct total tonnage band can be found in the factsheet(s) for the substance.

Regulatory context

Here you can find all of the regulations and regulatory lists in which this substance appears, according to the data available to ECHA. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance):

REACH - Registration, Evaluation, Authorisation and Restriction of Chemicals Regulation
POPs - Persistent Organic Pollutants Regulations
  • Proposals for new substances to be listed under the Stockholm Convention, and once agreed, to become subject to the POPs Regulation.
EU Ecolabel Regulation
  • Ecolabels - Restrictions for Hazardous Substances/Mixtures
    EU. Substances Rendering Goods Ineligible for EU Ecolabel, Article 6(6), Regulation 66/2010/EC, L 27/1, 30 January 2010 (Table 3 of Annex VI to CLP; Candidate List of SVHCs)

    This list contains: (1) the hazardous substances with harmonised classifications and labelling (i.e., Table 3 of Annex VI to CLP Regulation); and (2) the Candidate List of substances of very high concern (SVHC). The EU Ecolabel may not be awarded to substances or mixtures classified as such. Note that this list is not exhaustive. While the harmonised list covers many hazardous substances, others not listed may also meet classification criteria in accordance with the CLP Regulation.
