What your nose knows about class, control, and capitalism
I've been thinking about perfume lately.
Not the kind they hawk at department store counters or in those glossy magazine inserts that give you an instant headache. I'm talking about the entire concept of fragrance — this invisible force that has shaped civilizations, economies, and human behavior for thousands of years.
It's not frivolous. It's foundational.
The wealthy have always used scent as a way to distinguish themselves from the masses. The ruling classes of ancient Egypt weren't just building pyramids — they were developing sophisticated perfume extraction methods for jasmine and lotus. These weren't just pleasant smells. They were power, embodied in molecules.
When you understand the history of fragrance, you understand how the powerful have always controlled sensory experiences as a form of social stratification.
The Original Status Symbol
Long before designer handbags or luxury vehicles, there was perfume.
The Egyptians weren't just dabbing it on their wrists. They were soaking their homes, their temples, and even their tombs in it. Fragrance wasn't a personal accessory — it was environmental control. It transformed spaces. It altered experiences. It signaled to everyone who entered: this place belongs to power.
The Greeks and Romans followed suit. For them, perfume was refinement, a marker of civilization itself. The elites didn't just want to smell good. They wanted to exist in an entirely different sensory realm than the commoners.
This is how privilege has always worked. It's not just about having more — it's about experiencing the world differently at the most basic sensory level.
The Chemistry of Class Division
Fast forward to the 19th century, when the industrial revolution brought us synthetic organic chemistry.
This was the moment fragrance could have become truly democratic. Instead, it split into two distinct tracks:
Mass-produced synthetic scents for the working class
Rare, complex, natural fragrances for the wealthy
The technology that could have equalized access to pleasant environments instead reinforced the olfactory divide. The rich still had their rare essential oils extracted through labor-intensive methods that required tons of raw material (it takes 3,500 kilograms of rose petals to produce just one kilogram of rose oil).
Meanwhile, the working class got cheap synthetic approximations that never quite captured the complexity of the real thing.
Sound familiar? It's the same playbook we see with food, housing, healthcare, and education. Two-tier systems masquerading as progress.
The Environmental Price Tag
Here's what they don't tell you in those dreamy perfume commercials: harvesting these scents can be devastatingly extractive.
Take sandalwood. The highest quality oil comes from the heartwood of mature Santalum album trees. For centuries, these trees were harvested to the point of near extinction to satisfy the global appetite for that rich, creamy scent.
Or consider ambergris, a waxy substance produced in the digestive systems of sperm whales — once (and sometimes still) harvested for high-end perfumery.
The quest for rare scents has driven environmental exploitation across the globe, often in countries where environmental regulations take a backseat to profit.
This is always how luxury works. Something must be depleted for something else to be valuable. Scarcity isn't accidental — it's manufactured and maintained, often at terrible ecological cost.
The Industrial Fragrance Complex
Today, we're living in the age of the scented everything. Candles. Plug-ins. Diffusers. Sprays. Laundry products. Personal care items.
The global fragrance market is worth over $50 billion and growing.
But here's the kicker: while we're buying more scented products than ever, we actually know less about what's in them. Many "fragrance" ingredients aren't disclosed on labels due to trade secret protections. The very air we breathe in our homes has become privatized intellectual property.
Meanwhile, fragrance sensitivity and chemical sensitivity disorders are on the rise. For a growing number of people, just walking down the detergent aisle at the grocery store can trigger migraines, asthma attacks, or skin reactions.
The right to clean, unscented air has become yet another casualty of consumer capitalism. Your neighbor's dryer sheets are now your problem. Your coworker's perfume is now your respiratory distress.
The Wellness Washing of Scent
The latest twist in this saga is the "natural" and "wellness" fragrance industry.
Essential oils are marketed as healing, purifying, natural alternatives to synthetic scents. The language has shifted from luxury to therapy. From indulgence to self-care. From status to health.
But look at the price tags. Look at who can afford these "natural" alternatives. The class divides remain firmly intact, just rebranded for our wellness-obsessed era.
Don't get me wrong — many essential oils do have legitimate therapeutic properties. Peppermint oil contains menthol that can help with digestive issues. Lemongrass oil has antimicrobial properties. These aren't just pleasant smells; they're biologically active compounds.
But the wellness industry has expertly divorced these benefits from their historical context as folk remedies and traditional medicines, repackaging them as premium products for those who can afford to "care about their health."
The Scent of Resistance
So where does this leave us? Should we all just unplug our diffusers and embrace the natural human funk?
Maybe. But there's something deeper here worth considering.
Our relationship with scent reveals how thoroughly capitalism has colonized our senses. Even our most primitive, emotional responses to smell have been commodified and stratified by class.
But fragrance has another history too — one of resistance and reclamation.
For centuries, indigenous and traditional cultures have used aromatic plants as part of healing practices and spiritual ceremonies. These weren't luxury goods but communal resources, shared knowledge passed through generations.
The emancipatory potential of fragrance doesn't lie in buying the right essential oil diffuser. It lies in reclaiming our sensory autonomy from commercial interests. In recognizing scent as a commons rather than a commodity.
Taking Back Our Air
Here's what I propose:
Demand transparency. The "fragrance loophole" in labeling laws needs to end. We have a right to know what chemicals we're breathing.
Respect sensory boundaries. Your scent choices affect others. In shared spaces, this matters.
Decouple scent from status. Appreciate the chemistry and artistry of fragrance without using it as another way to signal class position.
Support ethical sourcing. If you do buy scented products, research companies that prioritize sustainable harvesting and fair labor practices.
Learn the chemistry. Understanding that rose oil contains citronellol and phenyl ethyl alcohol doesn't diminish its beauty — it enhances your appreciation while demystifying the marketing.
The history of fragrance shows us how something as fundamental as how we perceive the world through our senses has been shaped by power and profit. But it also shows the persistent human desire to create beauty, to transform spaces, to communicate through invisible means.
That desire doesn't have to be captured by capitalism. It can be reclaimed as a form of expression, connection, and even resistance.
So the next time you smell something beautiful — whether it's a fancy perfume or just the scent of rain on hot pavement — remember that your response to that scent is one of the few things truly your own.
Even if they've tried to sell it back to you in a bottle.
If you found value in this article, consider becoming a paid subscriber. Your support makes independent analysis possible in a media landscape increasingly controlled by corporate interests — including those that would prefer you not think too deeply about why everything suddenly needs to smell like something else.

Most Important Ideas/Facts:
Historical Context (Sources 1 & 2):
The culture of fragrances is ancient, with evidence in Egyptian, Greek, Chinese, and Indian civilizations.
"The Egyptians, Greeks, Chinese and Indians; all have voyaged deep into the art of aroma." (Source 1)
In ancient Egypt, perfumes were a luxury used in religious ceremonies and to aid the deceased. They were the first to develop techniques to extract essential oils from plants like jasmine and lotus. (Source 2)
The Greeks used fragrances in religious ceremonies and as a mark of refinement, developing more elaborate scents from plants like lavender and incense. (Source 2)
The Romans used perfumes widely in daily life to cover unpleasant odors and improved extraction techniques for use in public baths and homes. (Source 2)
During the Middle Ages, fragrances were primarily used to mask foul odors in crowded cities, with scent waters and perfumed compositions common. They were also used in churches and cathedrals for sacred atmospheres. (Source 2)
The Renaissance saw a rise in sophisticated perfumes among the wealthy, still used to mask odors but also for pleasure and to impress guests. Expensive ingredients like musk, amber, and sandalwood were used, and scented candles and fabric sachets became popular. (Source 2)
By the 17th century, perfuming everything from furniture to clothing was common among the rich, leading to the emergence of professional perfumers. (Source 2)
The 19th century saw home perfume remain a luxury, with diffusions through candles, incense, and oil burners. (Source 2)
Chemistry of Essential Oils (Source 1):
Essential oils are complex mixtures of volatile and aromatic compounds produced by living organisms, mainly plants.
More than 4000 aromatic and medicinal plant species provide essential oils used in various industries.
Chemically, essential oils consist of "terpenes, terpenoids (allylic, mono-, bi-, or tricyclic mono- and sesquiterpenoids) and other compounds such as phenylpropanoids, benzenoids, and low molecular weight aliphatic hydrocarbons."
Essential oils are readily soluble in organic solvents but insoluble in water.
They are secondary plant metabolites found in specialized secretory tissues/glands and play roles in plant defense and signaling.
The overall fragrance of an essential oil depends on the specific odor of its individual components, which is determined by structure and volatility.
The composition of essential oils includes hydrocarbons, oxygenated compounds, and sulfur and/or nitrogen containing compounds.
Terpenes are the largest group of natural fragrances, with monoterpenes, diterpenes, and sesquiterpenes being most abundant in plant essential oils. Terpenoids are oxygenated derivatives of terpenes.
Examples of important essential oil components mentioned include linalool, citronellal, citral (geraniol and neral), benzaldehyde, eugenol, cinnamaldehyde, d-limonene, santalols, methylanthranilate, and cineale.
Components of Perfume (Source 1):
A perfume consists of three basic components: "the solvent - primarily a mixture of ethanol and water; fixatives - natural or synthetic substances used to stabilize the vapor pressure and enhance the overall odour; and essential oils - a complex mixture of odour bearing compounds."
The human body processes scent through the olfactory system and/or by absorption through the skin.
Fragrances are typically volatile liquids and mixtures of essential oils (or aroma compounds) with fixatives and solvents.
Modern perfumery uses a mixture of both natural essential oils and synthetic aromatic chemicals.
The solvent, primarily ethanol and water, keeps the odoriferous substance in solution and contributes to the perfume's "note" (various scent fractions).
Fragrances are classified based on the ratio of essential oil to solvent, with Parfum having the highest concentration (15-30% essential oil) and Eau de Cologne having the lowest (3-5% essential oil).
Fixatives stabilize the vapor pressure, enhance the overall odor, reduce the evaporation rate, and improve the shelf life of the perfume.
Common natural fixatives include gums, resinoids, and animal products. Synthetic fixatives include odorless solvents with low vapor pressures and substances of low volatility.
Extraction Methods for Essential Oils (Source 1):
"Aroma Extraction or fragrance extraction" refers to isolating odoriferous compounds from raw materials.
Major methods include expression, distillation, extraction with volatile organic solvents, and enfleurage.
Drawbacks of traditional methods include potential denaturing of compounds due to heat, oxygen exposure, or chemical reaction with the solvent.
Solvent Extraction: Uses organic solvents (hexane, petroleum ether, ethanol) to dissolve odoriferous components. Produces "concrete" (waxy residue) which is then treated with alcohol to yield "absolute" essential oil. Best suited for animal secretory gland oils but also used for plants like jasmine and rose.
Expression: Also known as "cold-pressed," involves pressing, squeezing, or compressing raw plant materials. Primarily used for citrus fruit peels. Provides high-quality products with fragrances identical to the raw materials and is beneficial for heat-sensitive oils.
Distillation: The most popular method, involves heating volatile oils to vapor and then condensing. Techniques include water/hydro-distillation, steam distillation (most common commercially), and hydro-diffusion. Steam distillation keeps temperatures below 100°C, suitable for heat-sensitive oils.
Enfleurage: An older method using fats to absorb essential oils from flowers. Can be hot or cold. Cold enfleurage involves placing flowers on fat layers; hot enfleurage involves stirring ingredients in hot fat. Less popular now due to low oil concentration, handling difficulties, and rancidity of fats.
Innovative Techniques for Green Extraction: Driven by interest in cleaner methods.
Supercritical Fluid Extraction (SFE): Uses supercritical fluids (like CO2) with properties of both liquids and gases for extraction. CO2 is preferred for being odorless, colorless, non-toxic, non-flammable, and recyclable. Offers advantages over conventional methods, such as higher selectivity and lower energy requirements.
Microwave-Assisted Extraction (MAE): Combines microwaves with solvent extraction or is solvent-free. Offers higher extraction rates, shorter time, less solvent, and lower costs. Solvent-free MAE uses internal plant water heated by microwaves to rupture glands and release oils.
Major Essential Oils and Their Uses (Source 1):
India is a major producer and exporter of essential oils.
Rose Oil: Widely used in perfumery and cosmetics. Produced from Rosa damascena and Rosa centifolia. Labour-intensive extraction due to low oil content. Main industrial products are rose oil (otto/attar), rose water, rose concrete, and rose absolute, produced by hydro-distillation and solvent extraction. Rose absolute is more concentrated and reflects the true rose odor. Uses include cosmetics, anti-inflammatory, antidepressant (aromatherapy), antiseptic, and antiviral properties.
Sandalwood Oil: Obtained from the heartwood of Santalum species (Santalum album and Santalum spicatum). Composed mainly of sesquiterpene alcohols (α-santalol and β-santalol) responsible for the aroma. Composition varies with species, region, age, season, and extraction. Traditionally extracted by hydro-distillation, now also by steam distillation and supercritical CO2 extraction. Used as a long-lasting fragrance in perfumes and cosmetics, a base and fixative, and in Ayurvedic medicine for various ailments.
Peppermint Oil: From Mentha piperita L., native to the Mediterranean. Widely used in flavoring, perfume, and pharmaceutical industries. Abundant in oxygenated monoterpenes, especially menthol (30-50%) which provides the minty, cooling odor. Extracted by solvent extraction, Soxhlet, and steam distillation. Uses include food flavoring, perfumery, mouthwashes, and medicinal applications (IBS, nausea, digestive issues, cold, headaches).
Lemongrass Oil: From Cymbopogon citratus. A major source of essential oil used in pharmaceutical, flavoring, perfumery/cosmetics, and agriculture industries. Has a refreshing and calming aroma and possesses antioxidant, antimicrobial, antifungal, anti-inflammatory, and anticancer activities. Major components are terpenes, with citral (a mixture of neral and geranial) being predominant. Extracted by solvent extraction, steam/hydro distillation (most popular), and SFE. Hydro-distillation is simple and cost-effective with good yields.
Modern Home Perfumery (Source 2):
Home perfume is now a daily practice, used to diffuse pleasant smells and create atmosphere.
Available in sprays, scented candles, and electric diffusers.
Can be formulated with essential oils, plant extracts, synthetic aromas, or combinations.
Used for relaxation, stimulating energy/creativity, and eliminating unpleasant odors/purifying air.
The 20th century saw mass production make home scenting more accessible with candles and diffusers gaining popularity.
Today, the "cocooning trend" and the increased focus on well-being at home have made home fragrance even more important.
Technology is driving the evolution towards more environmentally friendly products like heat-powered essential oil diffusers.
Consumers are becoming more aware of ingredients and seeking natural and healthier options.

6. FAQ
What is the historical significance of home perfume?
The history of home perfume dates back to ancient civilizations like Egypt, Greece, and Rome. Initially, it was often linked to religious ceremonies, used to communicate with deities or aid the deceased in reaching the afterlife. In ancient Egypt, sophisticated techniques for extracting essential oils were developed for this purpose. The Romans later integrated perfumes into daily life, using them in public baths and homes to mask unpleasant odors. During the Middle Ages and Renaissance, while still used to cover unsanitary smells, home perfumes evolved to include notions of pleasure and impressing guests, utilizing more refined and expensive materials and innovative diffusion methods.
How have the purposes of home perfume evolved over time?
The purpose of home perfume has evolved from primarily religious or ritualistic uses in ancient times to more functional applications like masking odors in the Middle Ages. During the Renaissance and into the 19th century, it became a mark of luxury and pleasure for the wealthy, used to create pleasant atmospheres and scent various items within a home. With technological advancements and mass production, home perfuming became more accessible and diversified in the 20th century. Today, it serves multiple purposes, including creating a pleasant atmosphere, enhancing relaxation, stimulating creativity, eliminating odors, and purifying the air, reflecting a growing emphasis on well-being and personalized sensory experiences.
What are the basic components of a modern perfume?
A modern perfume typically consists of three basic components: the solvent, fixatives, and essential oils. The solvent, primarily a mixture of ethanol and water, is used to keep the odoriferous substances in solution and also contributes to the overall "note" or scent fractions of the fragrance. Fixatives, which can be natural or synthetic, are added to stabilize the vapor pressure of the perfume, enhance the overall odor, improve the stability of the essential oils, increase shelf life, and help in the proper blending of scents. Essential oils are complex mixtures of odor-bearing compounds, serving as the main source of natural fragrances.
What are essential oils and where do they come from?
Essential oils are a complex and diverse group of volatile and aromatic compounds. They are primarily produced by living organisms, most commonly from plants, in specialized secretory tissues or glands. However, certain animals also produce them. These oils can be isolated from various parts of a plant, such as flowers (like lavender, rose, and chamomile), leaves (like lemongrass and peppermint), bark (like sandalwood), seeds (like coriander), fruit peels (like lemon), and kernels (like bitter almond).
What are some of the major chemical groups found in essential oils?
Essential oils are chemically complex and contain several "aromatic" or odor-bearing compounds. These compounds can be broadly divided into four major groups based on their chemical structure: terpenes, terpenoids (which are oxygenated derivatives of terpenes), phenylpropanoids, and "others" which include benzenoids and low molecular weight aliphatic hydrocarbons. Terpenes, such as myrcene and limonene, and terpenoids, such as linalool and citral, are particularly abundant and widely used in the perfume industry.
What are some common methods used to extract essential oils from plants?
Several methods are used for the extraction of essential oils from plants, each with its own advantages and disadvantages. Common methods include:
Expression: Also known as cold-pressing, this mechanical method involves pressing or squeezing raw plant materials to extract the oil, often used for citrus fruit peels.
Distillation: This involves heating volatile essential oils to their vapor state and then condensing them back into liquid. Techniques include water or hydro-distillation and steam distillation, with steam distillation being widely used commercially.
Solvent Extraction: This method uses organic solvents like hexane or ethanol to dissolve the odoriferous components from the plant material, yielding "concretes" which are then further processed to obtain "absolutes." This method is often preferred for delicate floral scents.
Enfleurage: An older method that involves trapping essential oils within layers of purified fat. While less popular now, it was historically used, particularly for extracting oils from flowers.
7. How are fragrances classified based on their composition?
Fragrances, particularly liquid ones, are often classified based on the varying ratio of essential oil to solvent (typically alcohol). This classification essentially indicates the overall strength or concentration of the fragrance. Parfum (or Perfume) generally has the highest concentration of essential oil (15-30%) dissolved in alcohol.
