10 ppm and the shared jars that must declare it

Commission Regulation (EU) 2022/1181 revised the labelling rule for preservatives that release formaldehyde. The scientific committee for consumer safety had found that the earlier trigger of 0.05 percent did not protect people already sensitised to formaldehyde against contact dermatitis. Sell through for goods with the earlier wording ended on 31 July 2026, when full compliance became required.

Since that date, every finished cosmetic sold in the EU with total released formaldehyde above 0.001 percent, or 10 ppm, has to bear the words releases formaldehyde. The former trigger stood fifty times higher, at 0.05 percent or 500 ppm. For a buyer who scans for diazolidinyl urea, DMDM hydantoin or sodium hydroxymethylglycinate, the change matters in daily shopping. A cream once sold without a notice may now have to show one.

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

The option for makers that sell a single formula on both sides of the Atlantic is stark. Retain a formaldehyde releasing system and print the warning on common packs, including jars sold in the United States, or drop the releaser and rebuild preservation with fresh testing and sourcing. Plant extracts do not avoid the issue. A botanical toner 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 also moved on close dates. Commission Regulation EU 2026/78 applies from 1 May 2026 and replaces Annex V entry 7 to add Sodium o Phenylphenate alongside o Phenylphenol with a combined limit, after an opinion of 25 October 2024. That same regulation added fifteen substances classed as carcinogenic, mutagenic or toxic for reproduction to the prohibited list with no transitional period. Trimethyl borate and N,N methylenediacrylamide were prohibited from that May date with no sell through.

More changes lie ahead. Commission Regulation EU 2026/909 appeared in publication on 28 April 2026. For many affected goods, non compliant items may no longer be placed on the market from 1 January 2027, with remaining stock to clear by 1 July 2028.

In the United States there is no federal ban on PFAS in cosmetics, so origin and proof rest on the maker. Under the Modernization of Cosmetics Regulation Act, the Food and Drug Administration was asked to trace PFAS in cosmetics back to source and publish a safety report by 29 December 2025. State rules now hold greater force. Minnesota asked makers to disclose intentionally added PFAS, with the first deadline moved to 1 July 2026. Connecticut requires reporting and labeling for cosmetics and other goods from 1 July 2026, starting at the source.

What to watch is the pack in hand and the trail behind it. A US label that suddenly states releases formaldehyde does not mean formaldehyde was added as such at origin. It means the finished product exceeds 10 ppm of released formaldehyde in lab testing. The warning is aimed at protecting already sensitised shoppers, not at stating that all low level exposure is unsafe for all users. Which particular US goods pass that level is not known, since available records do not provide brand level testing data.

Read the back label slowly, then decide by skin history rather than fear and trace what is inside. If formaldehyde sensitivity is known, the new warning and longer allergen list make avoidance simpler to confirm.
