The US Food and Drug Administration's 2026 regulatory agenda includes a formaldehyde ban for hair products and new fragrance allergen labeling requirements for cosmetics, both flagged as proposals within the Department of Health and Human Services roadmap reported by regulatory consultancy CIRS Group.

Unlike a final rule, the agenda placement signals intent, not effective date. Formulators and brand owners should read the items as a planning trigger, not a stop-ship notice. The trajectory, however, points toward restrictions that have been on industry watchlists for more than a decade.

What would a formaldehyde ban cover?

The proposal targets formaldehyde in hair products, a category that historically includes keratin smoothing treatments, certain straightening services and some preservation systems. Formaldehyde and formaldehyde-releasing ingredients have sat under FDA scrutiny since at least the 2016 salon-air investigations and the 2023-2024 state-level phase-outs.

Keratin-treatment service menus built around glyoxylic acid or formaldehyde-releaser chemistry would absorb the largest disruption. Salon brands selling take-home kits with the same chemistry face the same compliance exposure. Procurement teams should expect reformulation briefs to circulate once the proposed text publishes in the Federal Register, at which point the comment clock starts.

How would fragrance allergen labeling change?

The agenda item references fragrance allergen labeling for cosmetics, an area already governed in the EU by Regulation 1223/2009 Annex III, which lists 26 declarable fragrance allergens above 0.001 percent in leave-on products and 0.01 percent in rinse-off.

If the FDA proposal mirrors the EU model, US brands would need to extend ingredient lines on packaging or digital channels to disclose individual allergens above threshold concentrations. Fragrance houses would carry the upstream disclosure burden. Contract manufacturers would need to retool component specifications and incoming-quality checks.

What does the agenda mean for compliance workload?

Both items sit in the proposed stage, meaning companies have a window to comment, prepare documentation and pre-build compliant variants. Compliance teams should expect to:

• Audit current hair-product portfolios for formaldehyde and formaldehyde-releasers
• Map fragrance compositions against likely threshold triggers
• Re-cost label real estate and digital disclosure infrastructure
• Brief sales teams ahead of retailer-facing questions

Distributors importing into the US would also need to review existing dossiers, since dual-market labeling has become the norm for brands serving both the EU and North America.

Why the timing matters

Placing both items on the 2026 plan signals the agency is willing to spend political capital on hair-product chemistry and fragrance transparency simultaneously. Industry has tracked each topic separately for years; bundling them within one fiscal-year agenda increases the likelihood of at least one rule advancing through proposed-text publication.

For brands sitting on EU-compliant formulas, the operational lift on fragrance labeling is largely incremental. For US-domestic keratin brands, the formaldehyde question is existential and requires cross-functional decision-making between R&D, legal and salon-channel sales.

What to watch next

The next data point is publication of the proposed rule in the Federal Register, which triggers the formal comment window and locks in scope language. Until that text appears, agenda items remain signals of intent rather than enforceable deadlines. Companies that begin portfolio mapping now will hold the advantage when comment-period strategy and reformulation sequencing become urgent.
