IFRA 51st and 52nd Amendments: What Candle Makers Need to Know

An Amendment is IFRA's batch of new and revised Standards, the ingredient limits and bans behind your fragrance oil's certificate. The 51st Amendment is the latest one IFRA has notified: its press release says "the notification of the 51st Amendment went out on 30 June 2023." The 52nd finished consultation on June 12, 2026, and IFRA expects to publish its formal Notification in January 2027. For a candle maker, an Amendment shows up as a new IFRA certificate from your fragrance supplier. I am a candle maker, not a lawyer, so this is a plain reading of IFRA's own documents.

Whose deadline is it?

Your supplier's. IFRA's guidance says "the timelines provided in the Standards refer to mixtures of fragrance ingredients (formulas) and not to finished consumer product(s)." Compliance "corresponds to the date of placement of fragrance mixtures on the market, meaning for them to leave a fragrance house."

So the clock runs on the date a fragrance oil leaves the fragrance house, not on the date your candle is poured or sold. What this means for you:

• Ask your supplier for the current certificate when a new Amendment is notified.
• Keep the old certificate with the batches you poured under it. The certificate names its Amendment, so it shows which rules it was written against.
• Do not assume a bottle you already own was reformulated. That is the supplier's call, so ask them.

What was the timeline for the 51st Amendment?

IFRA's Table 1 gives each timeline in months after the "letter of Notification" (June 30, 2023). The dates below are computed by me from IFRA's month counts, so treat them as arithmetic, not as IFRA's own dates.

In IFRA's words, "new creations" are fragrance mixtures whose brief was issued after the supply-chain information exchange period ended. "Existing creations" are mixtures already placed on the market in consumer products or already in development at that point. Which of the two applies to a given oil depends on your supplier's own history with it, so read the Amendment named on the certificate you hold.

What does the 52nd Amendment change?

IFRA's End of Consultation Letter, dated August 31, 2026, says the consultation ran from December 12, 2025 to June 12, 2026. IFRA will introduce 48 new restriction Standards (37 of them with an added check of systemic toxicity) and 15 revised restriction Standards, plus other changes. The Notification "will be published in the coming months, likely in the second or third week of January 2027."

The timelines are longer than the 51st: restrictions and specifications enter into force 11 months after the Notification date for new creations and 30 months after for existing creations. IFRA extended the preparation phase by two months. Here is how the clock works, with a made-up Notification date:

• Example Notification date: January 15, 2027 (made up, for illustration only)
• New creations: 11 months later is December 15, 2027 (computed)
• Existing creations: 30 months later is July 15, 2029 (computed)

The real dates come from the real Notification. I re-checked IFRA's news list on November 12, 2026, and it showed no Notification for the 52nd yet. Check it again before you rely on any date here.

Reed diffusers get a mention: the letter says there was support for moving them from Category 10A to 10B, and that the Category 10B phototoxicity limit will match rinse-off products (50 ppm). The final Standards come with the Notification, so treat that as expected, not done. If you make diffusers too, see which IFRA category your product is.

Does it change anything for candles?

The End of Consultation Letter does not mention candles or Category 12, so I cannot tell you either way. What can change is the limit on a particular oil, because new and revised Standards cover individual ingredients. Your oil's Category 12 line may move, or may not. The only way to know is to read the new certificate when your supplier issues it. The guide on how to read an IFRA certificate shows which row is yours.

One thing does not change with an Amendment: IFRA's guidance says a ban "applies to all final product applications, including non-skin contact applications." A banned ingredient is banned in candles too.

What to do now

• Find the Amendment named on each certificate you have. If it says 51st, it is the latest notified Amendment.
• Ask your suppliers when they expect to issue certificates for the 52nd.
• File each certificate with the batch records it covered, as in why keep candle batch records.
• Watch IFRA's news page for the Notification, and recheck your oil limits when it lands.

Common mistakes

• Treating the Amendment date as your own deadline. IFRA says the timelines apply to fragrance mixtures leaving the fragrance house.
• Quoting a "52nd Amendment in force" date before IFRA has published the Notification. Dates only start counting from the Notification.
• Throwing away old certificates. They are your record of what a past batch was checked against.
• Assuming the certificate is the whole safety check. IFRA says it "does not replace a safety assessment." For what else your supplier sends, see certificate versus SDS.
