New Data Availability System

A new Data Availability System is being developed by ECHA. To begin with this system will take over the responsibility of making REACH registration data available, once it is ready. We expect the first version to be publicly available by the end of January 2024.

Since ECHA aims to devote our maximum effort to this new system, we can no longer maintain REACH registration data on the current Dissemination Platform. As such once the IUCLID format change begins on 19th May 2023 we will no longer update REACH registered substance factsheets. The factsheets will remain online, but will not be updated.

As a consequence, REACH registration data will likewise not be updated in Infocards, Brief Profiles, the Advanced search, or the Nanomaterials on the EU market portal. We will inform you of what you can expect in the new System, along with details of when and where to find it.

We appreciate your understanding in the meantime.

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
  • Substances predicted as likely to meet criteria for category 1A or 1B carcinogenicity, mutagenicity, or reproductive toxicity, or with dispersive or diffuse use(s) where predicted likely to meet any classification criterion for health or environmental hazards, or where there is a nanoform soluble in biological and environmental media.
  • Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA.
PIC - Prior Informed Consent Regulation
Previous Legislations
  • Substances listed in the EINECS, ELINCS, or NLP inventories.
Construction Products Regulation
  • Construction Product Regulation - Annex I (3) - Hazardous Substances
    EU. Hazardous Substances for Purposes of Annex I (3) (Requirements for Construction Works), Regulation 305/2011/EU on Marketing of Construction Products, amended by Regulation 574/2014/EU, 28 May 2014

    This list contains a non-exhaustive inventory of substances taken from: (1) Table 3 of Annex VI to CLP; (2) the Candidate List of SVHCs; (3) Annex XIV of REACH (Authorisation List); (4) Annex XVII of REACH (Restrictions List); (5) F-gases subject to emission limits/reporting per Regulation 517/2014/EU; and (6) volatile organic compounds (VOCs) listed in the Ambient Air Directive 2008/50/EC. The basis of the list is Annex I(3) of the Construction Products Regulation 305/2011/EC, which stipulates that construction works must not have a high impact on human health or the environment as a result of: giving off toxic gas; emissions of dangerous substances, volatile organic compounds (VOC), greenhouse gases or dangerous particles into indoor or outdoor air; release of dangerous substances into drinking water, ground water, marine waters, surface waters or soil.

Cosmetic Products Regulation
  • Cosmetic Products Regulation, Annex II - Prohibited Substances
    EU. Prohibited Substances: Annex II, Regulation 1223/2009/EC on Cosmetic Products, as amended by Regulation (EU) 2022/1531, OJ L 240, 16 September 2022

    This list contains substances which are banned from use in any cosmetic products marketed for sale or use in the European Union.

General Product Safety Directive
  • General Product Safety Directive - Hazardous Substances
    EU. Hazardous Substances for Purposes of General Product Safety Directive (2001/95/EC), 15 January 2002, amended by Reg 596/2009/EC, 18 July 2009

    This list contains a non-exhaustive inventory of substances that fall within the European Union's hazardous substance definitions, as provided on: (1) Table 3 of Annex VI to the CLP Regulation 1272/2008/EC; (2) Annex III of Directive 2000/54/EC (Biological Agents); Candidate List of SVHCs; and REACH Annexes XIV and XVII (Authorisation and Restriction lists). They can be considered hazardous for purposes of the General Product Safety Directive 2001/95/EC.
