FDA's Fragrance Allergen NPRM Is Live (Or Days Away). Here's What It Changes.

The FDA's proposed rule on fragrance allergen labeling — the one MoCRA mandated by June 2024 but didn't publish until May 2026 — has either just dropped or is publishing this month. The Unified Agenda lists "May 2026" as the target NPRM date for RIN 0910-AI90, confirmed across three independent regulatory tracking sources as recently as April 7. The rule would require cosmetic manufacturers to identify which substances qualify as fragrance allergens and disclose them individually on product labels — ending the longstanding practice of hiding them under the single term "fragrance" or "parfum".

This is not a marginal label change. The word "fragrance" currently legally shelters an undisclosed compound mixture that can include phthalates, musks, and dozens of individual allergens — none of which are currently named on packaging sold in the US. When the NPRM drops, a public comment period of 60–90 days follows, after which a final-rule timeline is set. Brands that have built clean-fragrance positioning around opaque "fragrance-free" or "naturally scented" claims — without ever disclosing compound-level ingredients — are looking at a reformulation and relabeling cost they have not modeled.

The compliance pattern mirrors the EU's framework, mandatory since 2023 for cosmetics containing any of 82 listed allergens above a threshold. US clean brands already aligned with EU CPNP standards are ahead. US-only brands may not have begun the allergen audit at all. The primary burden falls on the middle tier: too large for the MoCRA small-business exemption, too small for dedicated regulatory infrastructure.

For clean fragrance specifically, this is the disclosure standard the category has been claiming to uphold voluntarily. The FDA is about to make it mandatory.

The number to watch: the FDA's December 2025 PFAS safety review — enabled by MoCRA's mandatory product listings — found PFAS-containing cosmetic products in 0.41% of total listed products as of August 2024. That's a floor, not a ceiling. The allergen rule will surface comparable data on fragrance compounds, making the gap between "fragrance-free" marketing and actual formulation content visible to regulators for the first time.
