The Complete Unofficial Fragrance Reformulation Timeline
Vintage DecantsHello fragrance fans, my name's John. I'm the owner and creator of "Vintage Decants". I'm not a perfumer, nor have I worked in the industry, I just love fragrance, especially vintage fragrance. My mind wants to dissect it like a puzzle lol. I took it upon myself to research and compile a complete unofficial reformulation guide for the fragrance community.
I first had the idea this was possible when I noticed shared scent-profile patterns. As an example, I noticed prior to 1992 oakmoss was often used very heavy and afterwards it wasn't. I also noticed every few years the fragrance industry would have shared changes within itself. This could include batch sticker formating, bottle styles, or packaging ques across many different brands. I figured they had to be linked between one another somehow? I discovered that after every new major mandate (reformulation) is when brands would often re-style themselves.
Using the full reformulation timeline, I also developed a new system to help identify your perfumes I call "Era-Dating". It takes out the guesswork when in search of purchasing unformulated fragrance. Hope this helps and happy Smelling!
Perfume Reformulations 101:
Firstly, depending on how serious you are about fragrance in my opinion the two biggest ingredient changes happened during 2006, and 2024 if you wanted the short and easy answer.
What makes early editions of fragrance special? First edition versions are going to be the closest to the perfumer's original creation and vision. When ingredients are removed or restricted, it's like trying to cook a recipe, without its original ingredients, expecting it to taste the same.
What are reformulations and why do they happen?
For most of the world, perfume ingredients are commonly regulated by IFRA (The International Fragrance Association) and the EU (European Union). Their goal is to make perfume universally safe for both our health and the environment, often targeting ingredients with allergy-causing components that could affect a percentage of the population.
The simplest way to think about it: The EU regulates (makes the law), and IFRA recommends (sets the industry standard). If a brand wants global distribution, it'll generally have to abide by IFRA's guidelines. You can learn more about IFRA's recalls in more detail through their official site here: https://ifrafragrance.org/standards-library
Some brands, like Dior, do an outstanding job adapting to new guidelines, having their perfumers modify the existing formula and then submitting them as new versions.
How to identify vintage perfumes (Easy methods):
- You can easily identify your vintage perfumes era if you know the formatting style of the ingredients listed on the box, see picture below. Most splash bottles are often vintage pre-2006 versions as well. For help with tracing older batch codes, I highly recommend visiting Raiders of the Lost Scent for a list of comprehensive guides organized by brand: https://raidersofthelostscent.blogspot.com/2014/03/all-batch-codes-in-one-page.html
2. For help with dating your batch codes within modern perfumery post-2005 you can use a batch code checking website like: https://www.checkfresh.com/
Universal markers to help date perfumes. Barcodes were introduced in 1989 to globally unify packaging. Using symbols for dating before then is not consistent.
Perfume reformulation facts and rules:
1. With the exact dates of reformulations varying by brand or perfume, you can't uniformly specify a mass reformulation by a single year. That's why I've selected three-year increments for the timelines. The years listed for the eras are what you can compare your batch codes with.
2. If you want to pinpoint the exact date of reformulation for a specific brand, you have to cross-reference images of boxes and bottles and identify when ANY new aesthetic changes first happened to it. Reformulations and batch variations always run concurrently with ANY new aesthetic changes to the box, bottle, or sticker.
Identified examples of pinpointed aesthetic changes (reformulations) for Davidoff Cool Water EDT, that align with eras 6, 7, and 8.
3. After an IFRA mandate is passed, newly created formulas are required to adhere to the new guidelines immediately, while pre-existing fragrances generally have up to two years to reformulate. Including the time it takes to manufacture, it could add another year on top of that. As an example, if a new mandate is passed in 2022, the newly-reformulated fragrance would hit the market between 2023 and 2025. However, some brands may even start a year BEFORE the mandates have even been passed! Think of reformulations like a deadline a brand has to adhere to. Some brands do it immediately, and some wait until the last minute.
4. You can also identify and locate reformulations through industry-shared timelines. They come in many forms, like putting new warning information on boxes, launching or cancelling specific fragrances, or even transferring ownership around shared timelines. I'll share some examples of these within this blog as well.
5. All images contained in this blog are for demonstrational purposes only. Dating a perfume through the color of its liquid or the icons listed on its box may have varied results.
6. Reformulations happen routinely every 3-5 years with grace periods attached to them. Think of the era dates like a dated contract for a perfume. If a fragrance sells well, it will be pushed to the next era. If it doesn't, it may be discontinued around the date of the next era. Reformulations cost time and money, and brands want to maximize the longest period of time before they're mandated to change a perfume's formula.
Introducing "Era-Dating":
Era-Dating gives you approximate reformulation timelines and what changes had took place during them. If you're not a heavy collector, you need only to be concerned with the reformulations that occurred in 2006, 2018, and 2023.
Era-dating index:
1. 1980-1982 - Removal of deer musk
2. 1984-1986 - Removal of Musk Ambrette
3. 1991-1993 - Restrictions on oakmoss, animalics, and mysore
4. 1995-1997 - Restrictions on tonka bean, clove, and carnation
5. 1999-2001 - Removal of animalics and mysore sandalwood
6. 2004-2006 - Allergen framework introduced with 30 standards
7. 2009-2011 - IFRA-compliant oakmoss mandated +17 standards (Designer Brands)
**2014 - IFRA-compliant oakmoss mandated +17 standards (Niche Brands)
8. 2016-2018 - Removal of lyral +9 standards
9. 2021-2023 - Removal of lilial + 73 standards
Era 1. 1980-1982: Removal of deer musk
In 1979, as a conservation issue, CITES (The Convention on International Trade in Endangered Species of Wild Fauna and Flora) banned the use of endangered natural deer musk within perfume.
The smell of natural deer musk can be animalic or it can also have a clean and comforting aroma similar to the smell of classic saddle soaps. Vintage Equipage by Hermes is a great example of a perfume that used natural deer musk with a soapy aroma. I've smelled deer musk from brands well into the mid-eighties, so this isn't a definitive reformulation. To identify this era other than a batch code (often cited during 1981) you'll have to find the timeline when an aesthetic change happened to the box or bottle. Often, this era is related to when a majority of brands switched from a decimal to a percentage for the "vol" symbol, but that's not always consistent.
"EMB codes" listed on boxes or bottles (made in France) are the only icon from this era with an equally shared timeline.
Era 2. 1984-1986: Removal of musk ambrette
In 1983 musk ambrette was completely removed from perfumery. It was a heavily used synthetic note as a low-cost/high-yield replacement for deer musk. Its smell was often compared to the smell of sarsaparilla.
To identify this era, you'll need to cross-reference when, either aesthetically or industry shared timelines happened for the perfume or brand (often cited during 1986).
*Examples of shared industry timelines:
1984: Warner turns into Warner/Cosmair
1986: YSL changes from Charles of the Ritz to Parfums Corp
1984: Guerlain changed its packaging to the gold and black boxes.
1986: Patou changes its numerical batch code, to alpha-numerical. (ETC)
Nitro musks may have given some perfumes a light orange (creamsicle) color, which seems to be dominantly absent after this era, I'm speculating?
Era 3. 1991-1993: Restrictions on oakmoss, animalics & mysore
To identify this era, perfumes with barcodes or green dot logos, were generally made after 1992.
For this era were covering/combining two reformulations.
1. Introduction to the modernization era, 1989-1991 (the barcode)
2. IFRA's amendment 25, 1991-1993 (the Green Dot logo).
1. The modernization/barcode era: This wasn't an officially mandated reformulation, but brands during this era were starting to subsidize their formulas for international mass production. The introduction of barcodes being printed on perfume boxes started roughly in 1989. This is what turned perfume from what was previously known as a regional luxury item (e.g., a US formula and a French formula). Into what could be sold as a unified worldwide commodity. To accommodate supply, some perfume houses traded in some of their harder-to-source raw materials for ingredients that favored low costs and high consistent yields. Personally, I find that these changes were generally small during this timeline. You can identify this era (often cited during 1989) if the box contains a barcode, WITHOUT a Green Dot symbol.
2. IFRA's Amendment 25/Green Dot era: Passed in 1990 with a majority of the reformulations taking place from 1991 to 1993, this was the first major reformulation that marked the transition from "voluntary suggestions" to the strict regulatory shared environment we have today. Fragrance houses realized they could be sued if they didn't comply. This led to mass reformulations where brands updated their entire catalogs simultaneously. New changes were placed on the following ingredients; Oakmoss and treemoss was restricted to 0.6% use. Nitro musks like musk xylene and musk ketone were removed. Voluntary restrictions were placed on animalic notes like castoreum due to growing ethical concerns. Mysore Sandalwood shortages from India also resulted in a reduced use of the ingredient during this era. You can identify this timeline (often cited during 1992) if the box or bottle has a Green Dot logo.
Examples of the appearance of oakmoss reduced in a formula. (Note the color change of the liquid)
Era 4. 1995-1997: Restrictions on tonka bean, clove, and carnation
In 1995, the 29th amendment from IFRA changed the allowable concentrations to three popular ingredients: Coumarin 1.6% (tonka bean), eugenol 0.5% (clove/cinnamon), and isoeugenol 0.02% (carnation). Oriental and fougere fragrances like Opium, Youth Dew, Cinnabar, Azzaro Pour Homme, and others, had to have their formulas slightly reconstructed.
Also, In 1996 the EU established the "international nomenclature of cosmetic ingredients". This mandated ingredient lists to be printed on ALL boxes, with the formatting to include a translation of the ingredients in multiple languages. (E.g., using both "aqua" and "water")
You can identify this era (often cited during 1997) if a perfume's ingredients have their translations listed in two languages on the box.
*Shared timelines:
1997: Azzaro pour homme changes It's bottle style
1995: Paco Rabanne pour homme changes It's bottle style
1996: Drakkar Noir changes It's box style
1997: Short list of ingredients appears on ALL Chanel boxes
1997: Short list of ingredients appears on ALL Dior boxes
Examples of ingredient lists with translations that first started to appear throughout 1994-1997
Era 5. 1999-2001: Removal of animalics and Mysore sandalwood
In 1997, the European Union's Council Regulation brought CITES rules directly into EU law (the same group that had deer musk removed in 1979). This strengthened the control over any CITES-listed species or their derivatives that were being imported or moved within the EU. This alongside other numerous conservation acts effectively removed most animalic and rare resources from mainstream perfumery. That meant synthetic alternatives would now be used for notes like ambergris, civet, castoreum, and mysore sandalwood. As an example to replace the castoreum in Bel Ami, a mixture of styrax, (wood resin) cumin, and birch tar was effectively used.
Now within modern perfumery, the use of any naturally based animalic ingredients is rare, but it can still be found within some high-end niche artisanal perfumery. You can identify this era (often cited during 2001) if the fragrance received new packaging or aesthetics around this time.
Shared industry timelines:
1999: YSL Adapts to the PPR-Gucci era
1999: Guerlain's Samsara, a dominant mysore sandalwood fragrance, changed its bottle style to a red colored bottle style
2001: YSL Kouros Fraicheur is discontinued (With civet)
2003: YSL Kouros Cologne Sport is released (Without civet)
An example of Guerlain's Samsara, which received aesthetic changes, signifying reformulations. (reductions/removals of mysore sandalwood).
Era 6. 2004-2006: Allergen framework introduced with 30 standards
In 2006 the 40th amendment introduced the QRA (Quantitative Risk Assessment) framework that is now known as "the long ingredient lists". Originally launched with a set of 30 ingredients with standards attached to them. A standard is defined as the allowable safe level (concentration) an ingredient can be used within a formula. Brands were required to list any ingredients on their packaging that had standards attached to them. Many companies knew this change was coming and some as early as 2004, were already updating their formulas. Not all designers for aesthetic reasons, wanted a long list of potential allergens listed on their box. In some cases, they had their perfumers reduce, remove, or substitute the ingredients with alternatives to shorten the lists.
This reformulation had dramatic effects for some fragrance profiles that relied heavily on raw materials. You can identify this era (often cited during 2005) if the ingredient list on the box is long.
You can identify this timeline if the ingredients listed on the box are long.
Era 7. 2009-2011: IFRA-compliant oakmoss mandated +17 standards (Designer Perfumes)
How a perfume looks after its ingredients are removed or altered. Most perfumes made after 2018 may have no natural pigmentation due to the removal or restriction of the raw materials in the formula. Synthetic ingredients do not age the same since they may contain little to no organic material.This is a combined era including amendments 43 (2008), 45 (2010), and 46 (2011).
In 2008, the IFRA 43rd amendment banned the use of natural oakmoss/treemoss within fragrance. Oakmoss known as Evernia prunastri, was a pivotal ingredient that was featured in almost every perfume for its fixative and harmonizing qualities. Afterwards the introduction of two replacements were:
1. Evernyl: A synthetic version of oakmoss, that could be used in higher concentrations at a cheaper cost but with a less naturalistic aroma.
2. Oakmoss Absolute (Low Atranol/IFRA Compliant): A treated version of oakmoss, with it's allergy causing molecules "atranol and chloroatranol" diluted from the formula.
In my opinion, treated oakmoss smells very close to natural oakmoss, but it's costly to produce the ingredient and has lower concentrations permitted (0.1%).
For fan's of smokey leather fragrances like Bel Ami, A*Men, etc. In 2014 the amount of Birch Tar that could be used within fine fragrance was highly restricted. Birch Tar had a smokey and dark resinous type of smell that was often used within leather fragrances.
Fragrance enthusiasts claim this was "classic perfumeries" last era, as the adaptation into synthetic ingredients continued to rise. Usually you can identify when this timeline occurred for most designer brands (often cited during 2010/11) if you see an abundance of icons listed on the batch sticker.
You can identify this era by when icons started to be placed on batch stickers from 2009-2011.
**2014 - IFRA-compliant oakmoss mandated +17 standards (Niche Brands)
This is generally the same reformulations that designer brands had already completed by 2011 described above. But for some reason most niche brands waited until after 2014 to remove the same ingredients. Notes like oakmoss (Parfums De Marly Lippizan) or birch tar (Creed Aventus) and Amouage all were still using absolutes in their formulas.Era 8. 2016-2018: Removal of lyral +9 standards
This is a combined era including both amendments 47 (2013) and 48 (2015).
The QRA framework continued to advance, creating numerous new standards for previously unrestricted fragrance notes.
The price of "treated" IFRA-compliant ingredients with their allergens removed was costly and because of that it inadvertently started to push mainstream perfumery voluntarily away from using them. This left primarily niche and designer private lines to continue the use of expensive treated natural materials.
Synthetic aroma chemicals were quickly becoming the industry standard. Synthetics are cheaper to source, with fewer ingredient restrictions placed on them. Notes like iso-E-Super, amberwood, and ambroxan would all continue to gain in popularity after this era.
Additionally In 2017, the official EU cosmetics regulation successfully banned lyral from fragrance, a synthetic version of lily of the valley. Lyral, known as Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde. Was a widely used aldehyde with fixative capabilities used within 40% of perfumes at the time. Made popular in fragrances like Versace L'homme, the Chanel Allure series, the Armani Code series, the L'Homme series, and countless others.
After this era, you may notice the color of the liquid may be a less cloudy, or different color, if any raw materials or Lyral were removed from the formula.
It's harder to broadly give clues to identify this reformulation (often cited during 2018). Sometimes the ingredient names like "Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde" were removed from the box, but this is not always constant. The best way to pinpoint when the reformulation happened is you'll have to cross-reference whenever a change happened to the bottle, box, or liquid color.
An example of the color change after EAU Sauvage Parfum's natural myrrh note was removed in 2017.
Era 9. 2021-2023: Removal of lilial + 73 standards
This is a combined era including both amendments 49 (2020) and 51 (2023).
In the 49th amendment passed in 2020, IFRA introduced the QRA2 framework, the Quantitative Risk Assessment 2. It's an updated and stricter version of what the QRA originally was. It included an additional 73 ingredients that received new standards. The system expanded from 11 categories to 12, with additional sub-categories for better organization.
The QRA2 also introduced "Aggregate Exposure Settings" for ingredients. A system that sets the allowable ingredient concentration within fragrance products, by recognizing that consumers may use other scented products daily.the (e.g. shower gel, lotion, soap, air freshener) This calculates the concentration for the ingredient that's deemed "safe", by looking at the total dose an individual may be exposed to from all sources. This heavily affected the scent-profiles within both designer and niche perfumery.
The 49th amendment also fully removed Lilial as an active ingredient. Lilial aso known as Butylphenyl Methylpropional, was a floral aldehyde known for its fixative and aromatic properties that was used in over 75% of modern fragrances to help provide depth and longevity. After its removal, the most successful reformulations have now been using a blend of these two fixatives to replicate a similar effect.
1. "Florol" that helps provide the body.
2. "Nympheal" that provides an airy and diffusive quality to the scent.
To help pinpoint the amendment 49 reformulation, (often cited during 2022) look for the removal of "Butylphenyl Methylpropional" from the ingredient list on the box.
To help pinpoint the amendment 51 reformulation, (often cited during 2024)look for the Tri-Man + Info-Tri icons on the packaging, see image below.
Listing 80+ allergens in text would take up the entire back of a perfume box. Regulators now encourage Digital Labeling, which allows brands to only provide the full list via QR code or online.
More tips to help identify perfumes made after 2023-2025. Some like the FSC logo or translated ingredients, may appear as early as 2017 for some brands.
The immense gravity of reformulations that occurred during 2023 and 2024, affected both mainstream and niche perfumery. Forcing some brands to uncharacteristically remarket their pre-existing fragrances as "2025" versions.
Examples of positive, neutral, and negative feedback regarding newly reformulated perfumes after 2023.
In closing:
As we step further away from the use of raw materials and head towards the synthetic revolution. I conclude; regardless if it's vintage or modern, fragrance is still great thanks to the skilled perfumers that are constantly adapting and evolving their craft alongside an ever changing palette of ingredients. Within a fragrances earliest formulas and batches are truly what's golden, with them being closest to the perfumers original creation.
My opinion is, It's the reformulations that cause the building blocks of great fragrances to fall apart, but I guess that's another part of evolution.
Cheers and enjoy the journey!
