Open your bathroom cabinet right now and count how many products list "fragrance" or "parfum" as an ingredient. Shampoo. Conditioner. Body wash. Hand soap. Face wash. Lotion. Cleaning spray. Laundry detergent. Dryer sheets.
That single word — fragrance — is one of the most consequential terms in consumer product labeling. And most people have no idea what it actually means, or how much it matters.
This post covers what synthetic fragrance is, why it appears in so many products, what it does inside your body and your home, and exactly which products to switch to in every room. No fear-mongering — just the facts and the practical next steps.
What "Fragrance" Actually Means on a Label
In the United States, the word "fragrance" on a product label is a legally protected trade secret. Under the Fair Packaging and Labeling Act, manufacturers are not required to disclose the individual ingredients that make up a fragrance blend. They list one word — fragrance — and that's all the law requires.
What that single word can represent is staggering. A single fragrance formulation can contain anywhere from a few dozen to several hundred individual chemical compounds. The International Fragrance Association (IFRA) maintains a list of over 3,000 materials that are used in fragrance manufacturing. Some are derived from natural sources. Many are entirely synthetic. A meaningful number are associated with health concerns that have been documented in peer-reviewed research.
The trade secret protection exists because fragrance formulations represent real intellectual property for the companies that develop them. A perfume house or personal care brand that has spent years developing a signature scent has a legitimate interest in protecting that formula from competitors. The problem is that this protection, designed for the perfume industry, has been applied to everything — laundry detergent, baby wipes, cleaning spray, hand soap — regardless of whether the scent serves any function beyond marketing.
What's Actually Inside "Fragrance"
While the specific formulation of any given product's fragrance is a trade secret, research over the past two decades has established a fairly clear picture of what fragrance compounds commonly contain and what they do.
Phthalates Phthalates are plasticizing chemicals used in fragrance formulations to make scent last longer on skin and fabric. They are among the most well-documented endocrine disruptors in the consumer product space — meaning they interfere with the body's hormonal signaling systems. Phthalates have been associated with reproductive health effects, developmental concerns in children, and altered hormone levels. They are absorbed through skin, inhaled, and detected in blood and urine after exposure to fragranced products.
Synthetic musks Musks are used to give fragrance a warm, lingering base note. Nitromusks — an older class — have been largely phased out due to toxicity concerns. Polycyclic musks, the replacement, are more stable, which means they are also more persistent: they accumulate in body fat, have been detected in human breast milk, and don't break down readily in the environment. Some are classified as possible endocrine disruptors.
Benzene derivatives Compounds like benzaldehyde, styrene, and toluene — all used in fragrance — are known or suspected neurotoxins. Benzene itself is a known carcinogen. These compounds are present in trace amounts in many fragrance blends and are released into indoor air through use of fragranced products.
Allergens The European Union requires disclosure of 26 known fragrance allergens when they appear above trace levels in products. The United States has no equivalent requirement. Many of these allergens — linalool, limonene, citronellol, and others — are present in products sold and marketed as "natural" or "gentle" because they occur in plant sources, but they are still clinically documented allergens that cause reactions in sensitive individuals.
Formaldehyde-releasing compounds Some fragrance preservative systems release formaldehyde — a known carcinogen — over time as a byproduct of their chemical breakdown. This is separate from formaldehyde in fragrance itself but is part of the broader picture of what undisclosed chemistry can mean in a product.
Why It Matters More Than You Might Think
The concern with synthetic fragrance is not exposure from a single use of a single product. It's cumulative, chronic exposure from many products used many times a day.
Consider a typical morning routine: scented body wash, fragranced shampoo and conditioner, scented lotion, perfume or cologne, a fragranced deodorant. Then the home environment: a laundry detergent with fragrance, clothes dried with dryer sheets, a kitchen cleaner with "fresh linen" scent, a hand soap that smells like lavender. The fragrance chemicals from each of these products are absorbed through skin, inhaled as volatile compounds evaporate into air, and in some cases ingested through hand-to-mouth contact.
For adults with healthy systems, this cumulative load is processed — not without consequence, but the effects are generally subclinical and build over years. For babies and children, the equation is different. Baby skin absorbs substances at a higher rate. Infant lungs are more vulnerable to airborne irritants. Hormonal and reproductive systems are in active development and particularly sensitive to endocrine-disrupting compounds during critical developmental windows.
This is why fragrance-free formulations are the standard in every baby product worth buying — and why extending that standard to the rest of the household products a baby is exposed to is worth taking seriously.
The Fragrance-Free Swap Guide, Room by Room
The good news: replacing fragranced products with genuinely fragrance-free alternatives doesn't require sacrificing performance. The products below are at Periwinkle specifically because they work — the absence of synthetic fragrance doesn't mean absence of efficacy.
Bathroom: Personal Care

Kitchen and Home Cleaning
Household cleaners are among the worst offenders for synthetic fragrance. "Fresh linen," "clean breeze," and "lavender mist" are marketing language for synthetic fragrance blends that linger on surfaces and circulate into the air of the rooms where you prepare food and where your children play.
- Puracy Everyday Multi-Surface Cleaner — $21.99 — plant-powered, residue-free, streakless, no synthetic fragrance, no sulfates or phosphates, safe on every surface
- Puracy Foaming Hand Soap — $19.99 — plant-based, mild foaming formula, cleans over 600 hands per bottle, refillable, no synthetic fragrance
- Dual-Sided Eco-Sponge 2pk — $7.99 — replaces the conventional sponge, which is one of the most microplastic-laden items in an average kitchen
Laundry Room
Laundry products are one of the most fragrance-saturated categories in the home — and because they go directly into fabric, whatever is in them ends up on your skin for hours at a time.
- Puracy Baby Laundry Detergent — $19.99 — fragrance-free, hypoallergenic, 4 plant-based enzymes, effective for the whole family
- Organic Wool Dryer Balls — $14.99 — replaces dryer sheets entirely, no synthetic fragrance, softens fabric mechanically

Baby Products
If there's one category where eliminating synthetic fragrance is most urgent, it's baby products. Fragrance-free should be the baseline expectation for every product that touches infant skin.
- Buddle Wonder Wipes — $8.00 — naturally-derived ingredients, no synthetic fragrance
- Puracy Organic Baby Lotion — $9.99 — organic aloe base, fragrance-free, gentle enough for newborns
- Puracy Baby Bubble Bath Hypoallergenic — $9.99 — pH-balanced, fragrance-free, safe for daily use on newborn skin
The Practical Approach: Where to Start
You don't need to replace everything at once. The highest-impact swaps — the ones that reduce the most fragrance exposure in the shortest time — are the products you use most frequently on the largest surface areas:
- Laundry detergent and dryer sheets (affect all clothing worn all day)
- Body wash and shampoo (daily, large surface area)
- Hand soap (used 10-20 times a day, often by everyone in the household)
- Multi-surface cleaner (affects the air and surfaces of every room)
- Baby products (highest urgency if you have an infant or are expecting)
Make those five swaps and you will have removed the vast majority of synthetic fragrance from your daily environment. Everything after that is refinement.

Frequently Asked Questions
Is fragrance always synthetic, or can it be natural? Both natural and synthetic fragrance compounds can appear under the word "fragrance" on a label. Natural fragrance derived from plant extracts can still cause allergic reactions and skin irritation in sensitive individuals, and it's still undisclosed. The most transparent products either list "fragrance-free" or disclose their scenting agents by name — for example, "scented with lavender essential oil" rather than the blanket term "fragrance."
What's the difference between "fragrance-free" and "unscented"? Fragrance-free means no fragrance compound — synthetic or natural — has been added to the formula. Unscented means the product has no detectable scent, but it may still contain a masking fragrance that neutralizes the smell of other ingredients. For sensitive skin and baby products, always look for fragrance-free rather than unscented.
Are "natural" or "plant-based" fragrances safe? Not automatically. Natural fragrance compounds derived from plants can still be allergens — limonene and linalool, found in citrus and lavender respectively, are among the most common contact allergens documented by dermatologists. The key question is not natural vs. synthetic but whether the specific compounds are disclosed and whether the formula has been tested for skin safety.
How do I know if a cleaning product is genuinely fragrance-free? Read the full ingredient list rather than trusting the front-of-label claim. Look for the absence of "fragrance," "parfum," and any essential oil that isn't serving a functional purpose. Products certified by third-party organizations like EPA Safer Choice or those with fully disclosed ingredient lists — like the Puracy products we carry — give you the most confidence.
Can synthetic fragrance cause allergies to develop over time? Yes, this is a documented phenomenon called sensitization. Repeated exposure to a fragrance allergen can sensitize the immune system so that future exposures — even at low concentrations — trigger a reaction. This is one reason why fragrance allergies are more common in adults than children, despite adults generally having more robust immune function: the allergy develops after years of cumulative exposure.
Is synthetic fragrance worse in some products than others? Yes. The worst offenders are products that stay on the skin or fabric for extended periods — leave-on lotions, laundry products (which affect clothing worn all day), dryer sheets, and fabric softener. Rinse-off products like shampoo and body wash are lower exposure than leave-on products, but still contribute to cumulative fragrance load. Cleaning products that aerosolize during use — spray cleaners, air fresheners — add an inhalation route on top of skin contact.
What about candles and air fresheners? Conventional scented candles and synthetic air fresheners are significant sources of indoor fragrance exposure through inhalation. When a fragranced candle burns, it releases those compounds into the air of your home. Non-toxic alternatives include beeswax or soy candles with no synthetic fragrance, and natural ventilation rather than synthetic air fresheners. We carry the 12oz Speckle Candle Vessel for those who want to make their own candles with clean, controlled ingredients.
