Key takeaway

What this development means

The Health and Safety Executive (HSE) has issued critical deadlines for companies wishing to participate in the GB Biocides Review Programme. Notifications to maintain market access for active substances, including DCDMH and DCEMH, must be submitted by 15 February 2025. Additionally, comprehensive dossiers for Chrysanthemum cinerariaefolium extract are due by 23 May 2025. Non-compliance will result in the prohibition of these substances in biocidal products and treated articles across Great Britain. Companies are urged to act promptly to ensure compliance and retain market access.

What happens if a notification for DCDMH or DCEMH is not submitted by 15 February 2025?

If a notification is not submitted for DCDMH (reaction products of 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin with bromine and chlorine) or DCEMH (reaction products of 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin with chlorine, CAS 89415-87-2), the HSE will issue a non-approval decision. This prohibits the use of these substances in biocidal products and treated articles in Great Britain. Companies must remove affected products from the market within the specified timeframe.

Who can submit a dossier for Chrysanthemum cinerariaefolium extract?

Only the person, company, or task force/consortium that successfully notified Chrysanthemum cinerariaefolium extract (from Tanacetum cinerariifolium, CAS 89997-63-7) for product types 18 and 19 can submit a dossier. The dossier must be submitted by 23 May 2025, or the substance will be subject to a non-approval decision.

The Health and Safety Executive (HSE) has announced key deadlines for companies to participate in the GB Biocides Review Programme, urging industry players to act promptly to retain their active substances' market access.

Notification Deadline: February 15, 2025

The HSE's open invitations focus on two active substances for product type 11:

DCDMH: Reaction products of 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin with bromine and chlorine.DCEMH: Reaction products of 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin with chlorine (CAS: 89415-87-2).

These open invitations, stemming from a withdrawal by the previous participant, Innovative Water Care LTD, allow new entities to step in and maintain these substances in the GB Review Programme​​.

Dossier Submission Deadline: May 23, 2025

Entities that successfully notify by February must submit comprehensive dossiers to HSE by this deadline to avoid non-approval decisions for:

Chrysanthemum cinerariaefolium extract for product types 18 and 19 (CAS: 89997-63-7).

Non-compliance will result in the substances being barred from biocidal products and treated articles in Great Britain​​.

Implications of Non-Compliance

Failure to meet these deadlines will lead to non-approval decisions. This entails a prohibition on the use of affected substances in biocidal products and treated articles, impacting market access significantly.
