IFRA 52nd Amendment: what changes, and when

This page tracks the 52nd Amendment to the IFRA Standards as it stands after the End of Consultation Letter of 31 August 2026. It is not yet the final text: formal Notification is expected in January 2027, and the figures below are those IFRA has committed to publicly, not a forecast.

One caveat to hold throughout, and it applies to every account of this process including ours: the source here is IFRA describing IFRA. The association writes the standards, publishes the consultation, and reports on its own outcome. That does not make the figures wrong, and there is no better source for them, but it is the reason a buyer should read the structural question of who authors these rules alongside the rules themselves.

What the 52nd Amendment contains

Item	Count
New restriction Standards, dermal sensitisation	48
of which with additional systemic toxicity evaluation	37
Revised restriction Standards, per latest RIFM assessments	15
Revised Standard, musk ketone	1
New specification requirement, acetylated vetiver oil	1
Revised Standards, phototoxicity	3

Phototoxicity limits for Category 10B products will be aligned with those for rinse-off products.

The furocoumarin limits: 1 ppm and 5 ppm

The single change with the widest reach on natural materials is the revised furocoumarin Standard, and the consultation confirmed an exposure-based approach rather than a flat ceiling: a 1 ppm skin contact limit for products intended for deliberate sun exposure, and 5 ppm for other leave-on products.

Furocoumarins are the reason citrus oils have always been the awkward family in a fine fragrance brief. The distinction the new Standard draws is between what a product is for, not what it contains, which is a different kind of rule to write a formula against: the same juice can sit either side of the line depending on the claim printed on the box.

The compliance clock: 11 months, then 30

The Standards enter into force 11 months after the date of Notification for new creations, and 30 months after that date for existing creations.

With Notification expected in the second or third week of January 2027, that points to roughly December 2027 for anything newly created and mid-2029 for products already on the market. IFRA has not published the exact dates, and they cannot be fixed until Notification, so treat those as arithmetic rather than as deadlines.

The asymmetry between the two is the operative fact. A house composing something new after Notification has under a year. A house reformulating a range it already sells has two and a half. That is generous in appearance and less so in practice, because reformulating an existing product is the harder exercise: the target is not “a compliant fragrance” but “the same fragrance, compliant”.

Why the reformulation work starts before Notification

There is a habit of treating Notification as the starting gun. On this amendment that would be a mistake, because the substance is already public.

The consultation ran from 12 December 2025 to 12 June 2026, and the End of Consultation Letter sets out the feedback received, IFRA’s rationale in response, and how it will be addressed in the final Notification. The list of affected materials and the direction of the limits are therefore known now. What January adds is the legal date, not the news.

For anyone holding stock of restricted naturals, or quoting a client on a formula that will still be selling in 2028, the useful work is already possible: identify which of the 48 touch the palette, check the furocoumarin exposure route against the intended claim, and find out whether suppliers can characterise the materials at the level the new Standards imply. That last one tends to be the long pole, as it was for the EU allergen list.

How to check a material in the IFRA Standards Library

This page gives the shape of the amendment, not its contents material by material. For a specific substance, the IFRA Standards Library is the authoritative lookup, and it is the only place where the current text and the amendment status of an individual Standard can be confirmed. Anything read here or in the trade press should be verified there before it goes into a formula or a quotation.
