Less than one year before the 21st ATP becomes mandatory, the European Commission has published the 22nd ATP.
The regulation will enter into force on the 20th of October 2024 and will be mandatory from the 1st of May 2026.
It introduces:
• 27 new entries with harmonized classification,
• 16 modifications to the classifications of existing entries,
• and the removal of 7 entries.
I quickly checked how many products in the portfolios of our customers are affected and found about 7,500 hits—slightly less than 10% of all products. That’s significant, especially since some common chemicals, such as formaldehyde, formic acid, n-hexane, and hexyl salicylate, are affected by this ATP.
It is also worth noting that the classification of silver is now harmonized in three ways based on particle size. The Commission opted for a less strict classification for reproductive toxicity (Category 2, H361f), despite proposals calling for the stricter H360 classification.
Here is a brief overview of the changes covering some of the most commonly occurring substances:
New entries
| Substance name | Identifiers | New classification | Remark |
|---|---|---|---|
| hexyl salicylate | CAS: 6259-76-3 EC: 228-408-6 |
H361d, H317 | May become forbidden in cosmetics due to H361d |
| 2,4-dimethylcyclohex-3-ene-1-carbaldehyde | CAS: 68039-49-6 EC: 268-264-1 |
H317 | Very common in fragrances, but H317 already used in practice |
| Silver (massive, powder, nano) | CAS: 7440-22-4 EC: 231-131-3 |
H361f, H373 (nervous system), H400, H410 (except massive) | M-factor 10 for powder (1000 for nano) |
| copper [specific surface area > 0,67 mm2/mg] | CAS: 7440-50-8 EC: 231-159-6 |
H400, H410 | M-factor (acute) = 10 |
Updates of existing entries
| Substance name | Identifiers | New classification | Remark |
|---|---|---|---|
| n-hexane | CAS: 121-43-7 EC: 203-777-6 |
H225, H361f, H304, H336, H372 (nervous system), H315, H411 | Occurs in over 2000 products in Chemius |
| formaldehyde … % | CAS: 50-00-0 EC: 200-001-8 |
H350, H341, H330, H302, H314, H317 | H317 is now category 1A |
| formic acid … % | CAS: 64-18-6 EC: 200-579-1 |
H226, H290, H331, H302, H314, H318 | Check the official text for SCL |
| glyphosate (ISO) | CAS: 1071-83-6 EC: 213-997-4 |
H318, H411 | Classification remained the same |
Note: Specific concentration limits (SCL) are ommited for clarity
Since the 21st ATP is not yet mandatory, I also invite you to read this post to ensure your chemical documentation is already updated for the upcoming changes. If maintaining an up-to-date database of safety data sheets, labels, and other chemical reports is challenging, please feel free to contact us via email or phone—our help is closer than you think.
