The regulatory framework for beauty and personal care products in the European Union is undergoing important technical updates. If your brand formulates with formaldehyde-releasing preservatives (FRPs), a critical compliance deadline has arrived that directly impacts your product labels, safety files, and retail inventory.
Under Commission Regulation (EU) 2022/1181, the EU has drastically lowered the threshold that triggers a mandatory warning for formaldehyde-releasing substances. Understanding these new labeling rules is not just about regulatory compliance—it’s about protecting your customers, avoiding costly product recalls, and maintaining your market access in one of the world’s largest cosmetics markets.
In this comprehensive guide, we cover everything you need to know about the new EU cosmetic labeling requirements, key compliance deadlines, and how to audit your product formulations.
What Are Formaldehyde-Releasing Preservatives (FRPs)?
While the direct use of formaldehyde as an ingredient is strictly prohibited in the EU (classified as a Category 1B carcinogen and Category 1 skin sensitizer under the CLP Regulation), certain preservatives are allowed under Annex V of the EU Cosmetics Regulation (EC) No 1223/2009.
These preservatives are designed to fulfill their preserving function by gradually releasing small, controlled amounts of free formaldehyde over time to prevent microbial growth.
Common formaldehyde releasers used in cosmetics include:
- DMDM Hydantoin
- Imidazolidinyl Urea
- Diazolidinyl Urea
The Core Regulatory Change: Regulation (EU) 2022/1181
The European Commission published Regulation (EU) 2022/1181 to amend the preamble of Annex V of the EU Cosmetics Regulation. This amendment introduces two massive changes:
- A 50-Fold Decrease in the Warning Threshold: Previously, cosmetic products only had to bear a consumer warning if the total amount of released free formaldehyde exceeded 0.05% (500 ppm). The new regulation drops this threshold to a microscopic 0.001% (10 ppm).
- New Warning Text: The wording of the mandatory label warning has been modified from “contains formaldehyde” to “releases formaldehyde”.
This warning applies to any finished cosmetic product where the total concentration of formaldehyde released exceeds 0.001% (10 ppm), regardless of whether one or multiple formaldehyde-releasing substances are present in the formulation.
The Science Behind the Decision
This regulatory tightening follows a scientific opinion from the Scientific Committee on Consumer Safety (SCCS). The SCCS concluded that the previous 0.05% threshold did not sufficiently protect consumers who are already sensitized to formaldehyde. However, their research highlighted that reducing the threshold by a factor of 50 (down to 10 ppm) would protect the vast majority of formaldehyde-sensitized individuals from developing allergic contact dermatitis and other adverse skin reactions.
Critical Compliance Deadlines: EU vs. UK
The transition timeline is divided into two phases to allow cosmetic brands to update formulations and labels:
| Requirement / Milestone | EU Compliance Date | UK Compliance Date |
| New Products Placed on the Market | July 31, 2024 (New formulations must comply) | July 15, 2026 (All products placed on the market must comply) |
| Existing Stock / Sell-Through Period Ends | July 31, 2026 (Unlabeled stock must be withdrawn) | January 14, 2027 (Products placed on the GB market before July 15, 2026 may continue to be sold through until January 14, 2027) |
1. The EU Deadlines (Regulation EU 2022/1181)
- July 31, 2024 (Placing on the Market): After this date, only products complying with the new 0.001% threshold and bearing the “releases formaldehyde” warning can be newly placed on the EU market.
- July 31, 2026 (Making Available / Retail Sell-Through): This is the hard deadline for existing stock. By July 31, 2026, the transition period ends completely. Any product remaining on store shelves that contains formaldehyde releasers releasing >10 ppm without the updated warning must be completely withdrawn from retail shelves and can no longer be sold or distributed in the EU.
2. The UK Alignment
If you sell in the United Kingdom, take note of the slight date variation:
- From July 15, 2026, Great Britain requires all finished products placed on the market containing formaldehyde-releasing preservatives above 10 ppm to carry the “Releases formaldehyde” warning on the label. This aligns with the EU standard but has a slightly different enforcement timeline. (Note: Northern Ireland, operating under the EU framework, follows the EU dates).
Step-by-Step Compliance Checklist for Cosmetics Brands
To avoid costly product withdrawals and ensure seamless compliance, cosmetic brand owners, manufacturers, and Responsible Persons (RPs) should execute this step-by-step action plan:
Step 1: Audit Your Product Formulations
Cross-reference your entire raw materials catalog and active formulations against Annex V of the EU Cosmetics Regulation. Identify any products containing DMDM Hydantoin, Imidazolidinyl Urea, Diazolidinyl Urea, or other FRPs.
Step 2: Test for Free/Released Formaldehyde
Do not guess your released formaldehyde levels. Work with a qualified testing laboratory to run analytical tests on your finished formulations to determine the exact level of free formaldehyde released under normal storage conditions. If the level is above 10 ppm (0.001%), you must act.
Step 3: Update Your Product Labeling:
If your formulations release more than 10 ppm of free formaldehyde and you choose not to reformulate, you must update your product labeling. Ensure the mandatory warning statement ‘releases formaldehyde’ is clearly visible, legible, and indelibly printed on both the outer packaging and the immediate container.
Step 4: Revise Your Technical & Safety Files
Your Product Information File (PIF) and Cosmetic Product Safety Report (CPSR) must reflect these updates. Ensure your safety assessor reviews and signs off on the safety documentation to confirm compliance with the updated threshold values of Regulation (EU) 2022/1181.
Step 5: Strategize Your Supply Chain and Inventory
Note that the EU retail sell-through deadline of July 31, 2026, has passed, meaning all unlabelled stock exceeding 10 ppm free formaldehyde must be completely off EU retail shelves. For Great Britain, while new non-compliant products could no longer be placed on the market after July 15, 2026, existing stock legally placed on the market before that date may continue to be sold through until January 14, 2027.
Reformulate or Re-label?
For many cosmetics brands, the introduction of a warning statement like “releases formaldehyde” on the label is a major marketing hurdle, as modern consumers increasingly look for “free-from” claims.
When evaluating your product portfolio, you have two pathways:
- Keep the Formulation & Re-label: This is often the faster, less expensive short-term option, but it requires accepting the consumer warning on your packaging.
- Reformulate with Alternative Preservatives: Many brands are choosing to phase out formaldehyde-releasing substances entirely, substituting them with alternative, modern preserving systems (like organic acids or multifunctional ingredients). While reformulation requires stability and challenge testing, it eliminates the need for the warning label and appeals to clean-beauty consumers.
Whichever path you choose, immediate action is required to maintain compliance: the EU retail deadline (July 31, 2026) has already passed, requiring non-compliant stock to be off EU shelves, while Great Britain’s final sell-through window for pre-existing stock ends on January 14, 2027.
