In brief
  • Old wording sell through ended 31 July 2026 and full compliance now applies
  • Warning now starts above 0.001 percent, alongside a wider fragrance allergen list
  • Shared US formulas face new labels or rebuilt preservation as states track PFAS

Ten parts per million is the number that now decides the label, and 31 July 2026 is when full compliance began after Commission Regulation (EU) 2022/1181 rewrote the labelling rule for preservatives that release formaldehyde. The scientific committee for consumer safety had found the former threshold of 0.05 percent too weak to shield people already sensitised to formaldehyde from contact dermatitis. Sell through for goods bearing the older wording ended on 31 July 2026.

From that date, every finished cosmetic sold in the EU whose total released formaldehyde passes 0.001 percent, or 10 ppm, has to bear the words releases formaldehyde. The prior trigger sat fifty times higher, at 0.05 percent or 500 ppm. For someone who scans for diazolidinyl urea, DMDM hydantoin or sodium hydroxymethylglycinate, the change is concrete. A cream once sold without a warning can now require one.

The same deadline carried a second labelling shift. 31 July 2026 was the date for first placing on the market goods that follow the broadened fragrance allergen list under Regulation (EU) 2023/1545. Stock already on the market before that date can still be made available until 31 July 2028.

For makers that sell a single recipe on both sides of the Atlantic, the option is stark. Retain a formaldehyde releasing system and print the warning on shared packs, even on jars sold in the United States, or drop the releaser and reconstruct preservation with fresh testing and sourcing. Plant preparations are not exempt from the issue. A botanical toner made with rose water or a tea infusion still calls for defence against yeast and mould once water is in the bottle.

Other EU ingredient rules changed on close dates. Commission Regulation (EU) 2026/78 applies from 1 May 2026 and replaces Annex V entry 7 to add Sodium o-Phenylphenate beside o-Phenylphenol with a combined limit, after an opinion of 25 October 2024. That same regulation put fifteen substances classified as carcinogenic, mutagenic or toxic for reproduction on the prohibited list, with no transitional period. Trimethyl borate and N,N’ methylenediacrylamide were barred from that May date with no sell through.

More revisions wait ahead. On 28 April 2026, Commission Regulation (EU) 2026/909 was published. For many affected goods, non compliant products may no longer be placed on the market from 1 January 2027, with remaining stock to clear by 1 July 2028.

No federal ban in the United States covers PFAS in cosmetics The Modernization of Cosmetics Regulation Act directed the Food and Drug Administration to review PFAS in cosmetics and issue a safety report by 29 December 2025. State rules now carry greater force. Minnesota asked makers to report intentionally added PFAS, with the first deadline extended to 1 July 2026. Connecticut requires reporting and labeling for cosmetics and other goods from 1 July 2026.

What counts is the pack held in the hand. A US label that suddenly bears releases formaldehyde does not mean formaldehyde was added as such. It signals the finished product passes 10 ppm of released formaldehyde. The warning seeks to protect already sensitised shoppers, not to state that every low level exposure is unsafe for every user. Which particular US goods pass that level remains unknown, since brand level testing data is not available.

Read the back label slowly, then let your skin history guide you more than fear Where formaldehyde sensitivity is known, the fresh warning plus the longer allergen list ease avoidance.
