The formulae for perfumes are typically closely guarded secrets, but sometimes they are sold or passed on when a company changes hands. When this happens, the new owners might change the formula, either intentionally or because they don't have access to the original. Over time, this can lead to significant differences between the original and modern versions of a perfume. For example, vintage bottles of Halston are likely to smell different from newer bottles, even if the new formula has been tweaked to get closer to the original scent. Some perfume enthusiasts collect vintage perfumes to compare old and new formulations. Sometimes, a new formulation can be better than an older one, as in the case of Mitsouko by Guerlain.

What You'll Learn
Fragrances can deteriorate over time
Fragrances can indeed deteriorate over time. While some perfumes can last for years, especially if stored correctly, others may begin to expire within a year. The length of time a perfume lasts depends on several factors, including its chemical composition, ingredients, and time since opening.
One of the most obvious signs that a fragrance has deteriorated is a change in scent. This could be a decrease in potency, or the development of sour, acidic, metallic, or plastic notes. A perfume may also smell more concentrated if the alcohol has evaporated, or if it has been exposed to too much oxygen, which can alter the molecules of the fragrance. In some cases, the perfume may develop hints of vinegar or other chemical notes, especially if the scent contains fats such as vegetable oils.
The colour of a perfume can also be an indicator of deterioration. Perfumes often have a yellowish tint, but when they go bad, they can turn a darker brown or amber colour, or become opaque.
Another sign that a fragrance has expired is a noticeable decrease in volume, as the alcohol evaporates.
If a perfume has expired, it is best to dispose of it, as using it could result in an unpleasant smell, skin irritation, or even an allergic reaction.

Nostalgia can distort our perception of a perfume
The sense of smell is a powerful aspect of human perception that can evoke vivid memories and emotions. The olfactory bulb, responsible for our sense of smell, is closely connected to the brain's limbic system, which is responsible for processing emotions and memory. This connection allows perfumes to have a profound impact on memory recall and can trigger a cascade of emotions and memories linked to specific scents.
The link between perfumes and memory is a fascinating and well-documented phenomenon. Perfumes often become a part of our personal history, as we associate different scents with significant phases of our lives. A single whiff of a familiar perfume can instantly transport us back in time, evoking nostalgic memories and emotions associated with that period. For example, the scent of a particular perfume may remind someone of a beloved family member, providing a tangible connection to their presence.
However, our perception of perfumes can be distorted by nostalgia. Over time, our memories of a perfume's scent may change, even if the formula remains the same. This distortion can occur due to the fading of details in our memory or the ageing of the perfume itself. In some cases, reformulations of vintage perfumes may also alter the scent, further contributing to a discrepancy between our nostalgic perception and the actual fragrance.
Additionally, the emotional resonance associated with fragrances encountered during highly emotional events, such as weddings or significant milestones, can enhance the nostalgic impact of perfume-induced memories. The brain's ability to associate scents with specific emotions intensifies the vividness and evocativeness of these recollections. This phenomenon is not limited to positive associations, as certain fragrances may evoke negative emotions or memories depending on individual experiences.
The complex interplay between perfume, memory, and emotion highlights the role of nostalgia in shaping our perception of fragrances. While a familiar scent can trigger fond recollections, it is important to acknowledge that our recollection of a perfume's scent may not always align with its objective characteristics. The subjective nature of scent memory and the potential for distortion over time underscore the multifaceted relationship between nostalgia and perfume perception.

Top notes are the most susceptible to damage
The scent of a perfume is made up of different notes that are layered to create a unified, pleasing perfume. These notes are classified according to how quickly they evaporate and how long they last. The three types of perfume notes are top notes, middle notes, and base notes. Top notes, sometimes referred to as head notes, form the top layer of a fragrance. They are the scents detected first after spraying a perfume and typically last for about 10 to 15 minutes. Their main purpose is to give off an initial scent and then transition smoothly into the next part of the fragrance.
The perception of a smell can also change over time, and it can be challenging to distinguish whether a perfume has truly changed or if it is simply our memory that has become unclear. Comparing vintage and modern formulations of the same perfume can help clarify this. For example, a vintage bottle of Halston may have turned more concentrated and slightly off, while a newer bottle may be closer to the original scent with its fizzy chypre freshness, even if the formula has been tweaked.
To protect top notes from damage, careful consideration is required during the perfume-making process. Top notes typically make up 20-40% of the formula, offering a fresh and inviting opening. Middle notes, or heart notes, then comprise about 50-75% of the blend, providing depth and emotion to the fragrance. Finally, base notes make up the remaining percentage, adding longevity and creating a well-balanced, enduring aroma.
In conclusion, top notes are the most susceptible to damage due to their volatile nature and the fact that they are the first to fade. However, this does not make them any less important in the overall fragrance experience. By working in harmony with middle and base notes, top notes help create a well-rounded and captivating perfume.

Perfumes can be restored by specialists
Perfumes are complex and delicate compounds, and like works of art, they can deteriorate over time. The top notes, or fresh scents, are often the first to be affected, and the perfume may become more concentrated and "off". While it is challenging to restore a perfume to its original glory, it is not impossible.
Some perfume enthusiasts suggest that thinning out semi-evaporated perfumes with perfumer's alcohol can help restore the scent. However, others have found that this method does not work, and the scent is simply less concentrated but still degraded. Another method is to dilute the perfume with an alcohol-based fixative such as vodka. This can make the perfume lighter and more subtle, but it takes a lot of alcohol. For example, two sprays of perfume may require 1.5 teaspoons of vodka. It is recommended to leave the mixture to age in a dark area for four weeks.
Some people suggest that rather than trying to restore the perfume directly, it is better to create a mix to apply separately alongside the perfume. This could involve high-resolution fractional distillation and/or chromatography to determine which fractions to keep and which to discard and what to add back in with fresh material.
In some cases, a new reformulation by specialists can bring a perfume closer to its original scent, or even improve upon it. For example, the perfume Mitsouko by Guerlain has been expertly balanced and restored by perfumers, and the newer versions are considered superior to those from 15 years ago. Similarly, the newer versions of Samsara and Cabochard are considered to be of better quality and closer to the original scent, even if they are still not exactly the same.
While it may not always be possible to perfectly restore a vintage perfume, with experimentation and the help of specialists, it is possible to bring these fragrances closer to their former glory.

Alcohol content determines the concentration of a fragrance
The concentration of a fragrance is determined by its alcohol content. Ethyl alcohol is the main component of perfumes in terms of concentration, typically comprising 60% to 95% of the total mixture. It serves as a solvent, diluting the fragrance oils and enabling their dispersion. This dilution process is essential for the perfume to be safely applied to the skin. To ensure an even distribution of the fragrance, the fragrance oils are added gradually to the alcohol and thoroughly mixed.
The concentration of alcohol in colognes, for instance, can be as high as 88%. Colognes are characterised by their light and fresh scent, typically worn during the summer. Due to their high alcohol content, colognes have a relatively short duration, usually lasting a maximum of four hours.
On the other hand, perfume extracts, also known as "perfume" or "parfum", contain a lower concentration of alcohol, ranging from 60% to 80%. This type of fragrance is highly potent, with a strong and long-lasting scent that can persist for several hours or even days. Because of their high concentration of essence, typically ranging from 20% to 40%, perfume extracts are used sparingly to avoid being overpowering.
The concentration of fragrance oils in a perfume dictates its strength and longevity. Perfumes with a higher concentration of fragrance oils, typically ranging from 15% to 30%, are the most potent and provide a rich and enduring scent experience. These perfumes are often recommended for special occasions or when one wishes to stand out.
The process of crafting a perfume involves both art and science. Accurate calculations of proportions and concentrations are crucial to creating a fragrance that not only smells pleasant but also performs as intended. The maturation process, also known as "macération", is an essential step in perfume creation. During this process, the perfume is allowed to age for several weeks, enabling the scents to blend harmoniously and develop their full character.
Over time, perfume formulations may undergo changes, leading to variations in their scent. This can be due to reformulations, changes in ownership, or the unavailability of certain ingredients. In some cases, reformulations done with care and by specialists can restore a perfume closer to its original glory, as seen with Mitsouko by Guerlain and other fragrances.

Frequently asked questions
An old formula in perfume refers to a fragrance that has been reformulated to match newer standards or to improve its scent profile. This can be due to changes in the company's ownership, the perfumer's interpretation, or the availability of ingredients.
Perfume formulas can change for various reasons. One reason could be that the original perfumer who created the fragrance has passed away, and the new owners do not have access to the original formula. Additionally, certain ingredients may become prohibited or unavailable, necessitating a reformulation.
Comparing vintage and modern formulations can help identify an old formula. If you have access to an older bottle, you can compare the scent with a newer version. Changes in the top notes, concentration, and overall scent can indicate a reformulation.
It depends on individual preferences. Sometimes, a reformulation can be done poorly, resulting in a scent that is unrecognizable from the original. However, in other cases, a new formula may be an improvement, with better ingredients or a more balanced composition.
Yes, there are a few resources you can explore to find vintage perfume formulas. Books, such as "The Formulation & Preparation of Cosmetics, Fragrances & Flavors" by Louis Appell, offer insights into vintage formulas. Additionally, websites like Basenotes and Fragrantica provide discussions and comparisons of vintage and modern perfumes.
