In June 2024 the European Chemicals Agency ECHA updated the Candidate List with one new substance of very high concern (SVHC): Bis(α,α-dimethylbenzyl) peroxide, EC-number 201-279-3, CAS-number 80-43-3 This substance were already included in the PRIO database at the priority level phase-out substance since it has a harmonized classification as reproductive toxicant (Repr. 1B). The substance has been updated with the reference REACH Regulation (EC No 1907/2006), Candidate List.
We have now published information about which criteria changes have been made in PRIO since the new launch in October 2020. You can find the information on Start/PRIO criteria for phase-out substances and priority risk-reduction substances.
PRIO has been updated with a new substance group, Bisphenols, which includes around 20 structurally similar substances. The new substance group facilitates the identification of substances which, for example, are structurally similar to bisphenol A, and which are covered by PRIO's criteria.

PRIO is updated with the 2022 reported Products register data. The Swedish Chemicals Agency's Products register contains information on the use of substances in chemical products manufactured in or importeted to Sweden.
Two new criteria have been introduced in PRIO and three existing criteria have been updated. The new and updated criteria in PRIO are a consequence of the four new hazard classes being adopted and implemented in the CLP regulation. The changes mean that more substances with environmental and health hazards are covered by the criteria in PRIO and several new substances have been added to the database. Two new criteria PMT/vPvM - substances that are persistent, mobile and toxic or very persistent and very mobile at the phase-out substance level Potential endocrine disrupting – substances that are suspected endocrine disruptors for human health or the environment at the priority risk-reduction substance level Changes to three existing criteria PBT/vPvB – substances that are persistent, bioaccumulative and toxic or very persistent and very bioaccumulative at the phase-out substance level Potential PBT/vPvB - substances that are suspected to be persistent, bioaccumulative and toxic or very persistent and very bioaccumulative at the priority risk-reduction substance level Endocrine disrupting – substances that are endocrine disruptors for human health or the environment at the phase-out substance level Read more about the PRIO criteria for phase-out substances and priority risk-reduction substances
The twenty first technical adaptation of the CLP Regulation, ATP 21, has now been adopted by the European Commission and published in the EU Official Journal. The amendment includes additional substances with harmonised classification to Annex VI of the CLP Regulation. For some substances listed in Annex Vl, ATP 21 implies that the classification has been revised. With the support of ATP 21, approximately 30 substances, which meet the PRIO criteria for phase-out substances or priority risk-reduction substances, were added to the PRIO-database.

These substances are included in PRIO with the reference Candidate List .
The materials module in PRIO has been updated with additional information for substances on the EU´s Candidate List. The information is retrieved from the Swedish Chemicals Agency project “Kunskapssammanställning: Användningsinformation för ämnen på kandidatförteckningen” (H22-07569) which was carried out in 2022.
PFAS, US EPA Master List has been added as a new reference in PRIO. The US Environmental Protection Agency (US EPA) has set up a comprehensive database of PFAS substances (PFAS Master List) based on several internal and external sources. The reference PFAS, US EPA Master List in PRIO refers to as selection of PFAS substances from this database that fulfils the OECD PFAS definition (2021) and that have associated CAS numbers. As a results of the addition of a new reference, 5700 new PFAS substances were added to the PRIO database. PRIO now contains a total of almost 11 000 PFAS substances. All PFAS substances in PRIO fulfils the OECD PFAS definition from 2021. It is also the OECD's definition of PFAS that was used as the basis for the EU restriction proposal for PFAS* that Sweden together with 4 other member states submitted to Echa in February 2023. *In the current proposal a few types of PFAS subgroups that are considered as degradable are excluded from the scope of the restriction.

Today, the Swedish Chemicals Agency publishes a new report investigating hazardous chemicals that hinder material recycling of plastics. The report is part of the government assignment Non-toxic from the start . The material module in PRIO has been updated with new information on hazardous substances in plastics from the investigation. The two new sources of material information are; Rapport 3/23: Problematiska ämnen i plast som hindrar återvinning and PM 2/23 Ämnen som hindrar eller försvårar återvinning av plast i prioriterade produktgrupper inom byggsektorn. Rapport 3/23: Problematiska ämnen i plast som hindrar återvinning (in Swedish only). PM 2/23 Ämnen som hindrar eller försvårar återvinning av plast i prioriterade produktgrupper inom byggsektorn (in Swedish only). Read more about Substances in materials.

In June 2022, Perfluorohexane sulfonic acid (PFHxS), its salts and PFHxS-related compounds was added to the Stockholm Convention for global phase-out. In May 2023, this ban was implemented in EU legislation via the POPs Regulation. PRIO has now been updated with a new substance group, Perfluorohexanesulfonic acid (PFHxS) and its derivatives, containing substances from the indicative list in the Stockholm convention (UNEP/POPS/POPRC.15/INF/9) and ECHA's example list of PFHxS substances in the POPs Regulation. The substance group Perfluorohexanesulfonic acid (PFHxS) and its derivatives can be found under Advanced search in PRIO. There are now a total of 175 substances in this substance group. In connection with this review, the reference Stockholm Convention has been reviewed in its entirety and around forty additional substances have been added.
PRIO has been updated with data reported to the Products register data in 2021. The Swedish Chemicals Agency's Products register contains information on the use of substances in chemical products.
In May 2023, a decision was made to add an additionally three substances or substances groups to the Stockholm Convention for global phasing out. The three newly added substances are: Methoxychlor (CAS-Number: 72-43-5, EC-Number: 200-779-9) Dechlorane Plus (Several CAS/EG-Number, e.g., CAS-Number: 135821-03-3, 135821-74-8, 13560-89-9) UV-328 (CAS-Number: 25973-55-1, EC-Number: 247-384-8) These substances were already included in the PRIO database. Dechlorane Plus and UV-328 are both identified as SVHC substances on the Candidate List in the REACH regulation (EC no. 1907/2006). Methoxychlor, which previously met the criterion of potential PBT/vPvB in PRIO, has now been updated to PBT/vPvB at the priority level phase-out substance with the references Stockholm Convention .
In June 2023 the European Chemicals Agency ECHA updated the Candidate List with two new substances of very high concern (SVHC): Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide, EC-number 278-355-8, CAS-number 75980-60-8 Bis(4-chlorophenyl) sulphone, EC-number 201-247-9, CAS-number 80-07-9 These substances were already included in the PRIO database as priority risk-reduction substances , and have now been updated to the higher priority level phase-out substances with the reference REACH Regulation (EC No 1907/2006), Candidate List.
PFAS, ChemSec SIN List has been added as a new reference in PRIO. The SIN List is the International Chemicals Secretariat's (ChemSec) list of substances which, based on their assessment, meet the criteria for being substances of very high concern (SVHC) according to the REACH regulation. The SIN List includes a selection of PFAS substances with registered uses (production or import) in the EU and/or the USA. The reference PFAS, ChemSec SIN list refers to PFAS substances on the SIN List. As a results of the addition of a new reference, 187 new PFAS substances were added to the PRIO database. PRIO now contains a total of 5220 PFAS substances.
PRIO is updated with the 2020 reported Products register data. The Swedish Chemicals Agency's Products register contains information on the use of substances in chemical products. Within a few weeks time we will publish the 2021 data.
The search function in PRIO is now open after a period of downtime. The reason for the downtime was a system update that turned out to be more extensive than planned.
In January 2023 the European Chemicals Agency ECHA updated the Candidate List with 9 new substances 1,1'-[Ethane-1,2-diylbisoxy]bis[2,4,6-tribromobenzene], EC-number 253-692-3, CAS-number 37853-59-1 2,2',6,6'-Tetrabromo-4,4'-isopropylidenediphenol (TBBPA), EC-number 201-236-9, CAS-number 79-94-7 4,4'-Sulphonyldiphenol (bisphenol S), EC-number 201-250-5, CAS-number 80-09-1 Barium diboron tetraoxide, EC-number 237-222-4, CAS-number 13701-59-2 Bis(2-ethylhexyl) tetrabromophthalate, covering any of the individual isomers and/or combinations thereof Isobutyl 4-hydroxybenzoate, EC-number 224-208-8, CAS-number 4247-02-3 Melamine, EC-number 203-615-4, CAS-number 108-78-1 Perfluoroheptanoic acid and its salts (PFHpA) Reaction mass of 2,2,3,3,5,5,6,6-octafluoro-4-(1,1,1,2,3,3,3-heptafluoropropan-2-yl)morpholine and 2,2,3,3,5,5,6,6-octafluoro-4-(heptafluoropropyl)morpholine, EC-number 473-390-7 These substances or substance groups are included in PRIO with the reference Candidate List . Melamine is not associated to a criteria for phase-out substances in PRIO but is considered a phase-out substance as it is included in the Candidate List in accordance with Article 57(f) of the REACH regulation. The inherent properties of melamine is therefore of comparable concern as to other phase-out substances in PRIO.
PRIO now applies the OECD PFAS definition from 2021 (previously the PFAS definition in KIFS 2018:4 was used) and has consequently been updated with new PFAS substances from the OECD PFAS list (2018). The PFOA group in PRIO has been updated with new substances from the latest update of the Stockholm Convention's indicative list of substances covered by the restriction (UNEP/POPS/POPRC.17/INF/14).
