The Health and Safety Executive (HSE) of the United Kingdom has proposed the addition of diisohexyl phthalate (DIHxP) to the list of compounds subject to authorization (Annex 14) for UK REACH in its January 17, 2024, ebulletin. DIHxP, identified as a priority by the European Chemicals Agency (ECHA), was included in the recommendation for substances under the European Union (EU) Registration, Evaluation, Authorization, and Restriction of Chemicals regulation (REACH) on April 12, 2023.

Crucial Regulatory Step: HSE's Second Recommendation

Highlighting the significance of this proposal, the HSE emphasizes that the Secretary of State for the Department of Environment, Food and Rural Affairs (Defra), along with the Scottish and Welsh Ministers and the Appropriate Authorities, will collectively determine whether DIHxP should be added to Annex 14. This marks the HSE's second recommendation as the regulatory agency for UK REACH.

European Union Precedent: ECHA's Recognition of DIHxP

The recommendation to include DIHxP in the UK REACH Authorization List aligns with the European Union's precedent, as endorsed by the ECHA. The prioritization of DIHxP and its subsequent inclusion in the EU REACH regulation underscores the collective commitment to robust chemical management and safety measures.

Decision-Making Process: A Collaborative Effort

The decision to add DIHxP to Annex 14 is a result of collaborative efforts made by various key authorities. This reflects the commitment of regulatory bodies to maintain strict standards. The decision-making process was comprehensive and well-informed, with the involvement of the Secretary of State for Defra, Scottish and Welsh Ministers, and Appropriate Authorities.

As this regulatory process unfolds, the proposed inclusion of DIHxP in the UK REACH Authorization List signifies a proactive approach to chemical safety, reinforcing the UK's commitment to robust regulatory measures.
