Key Regulatory data, the new Classification & Labelling (C&L) Inventory, and REACH Registration data can now be found in ECHA CHEM. For the time being regulatory data here are still updated daily. The old C&L Inventory was last updated on 30 September 2025. REACH Registration and C&L Inventory data will be removed from here by 18 December 2025. Due to a technical upgrade and the coming holidays, data on ECHA CHEM will remain frozen between 5 December 2025 and 10 January 2026.

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):

  • 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.
  • Substances for which classification and labeling data have been submitted to ECHA in a registration under REACH or notified by manufacturers or importers under CLP. Such notifications are required for hazardous substances, as such or in mixtures, as well as for all substances subject to registration, regardless of their hazard.
Food Contact Recycled Plastic Materials and Articles Regulation-repealed
  • FCMs Recycled Plastic & Articles Regulation - Annex I - Authorised Use
    EU. Plastic Food Contact Materials (FCMs) per Regulation 10/2011/EU (Union List), Directive 282/2008/EC on Recycled Plastic FCMs, 28 March 2008, amended by Regulation 2015/1906/EU, 23 October 2015

    This list contains the Annex I Plastic Food Contact Materials (FCMs) authorised for use in the European Union under Regulation 10/2011/EU. Pursuant to Art. 4(b) of Directive 282/2008/EC on recycled plastic FCMs, plastic recycling processes can only be authorised if input originates from plastic materials and articles manufactured in accordance with EU legislation on plastic food contact materials and articles.

Plastic Materials and Articles Regulation
  • FCM and Articles Regulation, Annex I - Authorised Substances
    EU. Union List of Authorized Substances: Annex I, Plastics Food Contact Regulation 10/2011/EU, as amended by Regulation (EU) 2026/245, OJ L of 3 February 2026

    This list contains the Union list of authorised monomers, other starting substances, macromolecules obtained from microbial fermentation, additives and polymer production aids. It is taken from Annex I of the Commission Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with food.
