Disclosed waxes and wicks, and scents that know when to stop. What the word "fragrance" hides on a label in the US and Europe, what a candle maker can tell you and often doesn't, and five perfumes and candles from houses that show their work.
We choose from published evidence: ingredient lists, the maker's own disclosures, certifications we look up on the certifier's records, and reputable coverage. We have not worn, smelled or burned any of these products. This piece contains no affiliate links yet; when it does, they will be disclosed here.

A beautiful scent is one of the oldest luxuries in the house: a perfume worn close, a candle lit at the end of the day. It is also the place where labels say the least. One word, "fragrance" or "parfum," can stand in for dozens of materials, and a candle box may tell you the notes in poetry and the wax not at all.
This edit starts with what the label is required to say, in the United States and in Europe, and what it is not. Then come five picks from houses that publish what is inside: two perfumes whose makers list every material, and three candles whose makers disclose their wax, wick and scent or whose candles hold a certification we found on the certifier's own records. Every claim is attributed to whoever makes it. Where a famous house does not disclose, we say so plainly. "Clean" here means what our Clean Standard says: the materials are disclosed, and where a recognized certification exists, the product holds it on the certifier's own records. It is not a claim that any perfume or candle is safe, or safer than another.
On a cosmetic's ingredient list, the FDA allows fragrance and flavor ingredients to be listed simply as "Fragrance" or "Flavor" 1. The reason, the FDA explains, is that the law behind ingredient labeling, the Fair Packaging and Labeling Act, cannot be used to force a company to disclose trade secrets 2, and fragrance formulas, complex mixtures of many natural and synthetic ingredients, are the kinds of cosmetic components most likely to be trade secrets 1.
Two words on the box mean less than they seem. The FDA says there is no federal standard or definition for "fragrance-free" 4, and that even some products labeled "unscented" may contain fragrance ingredients, added in just enough quantity to mask the smell of other ingredients without giving the product a noticeable scent 1. The FDA also keeps a page on common allergens in cosmetics, including fragrance ingredients and essential oils 4.
Allergens are where US rules are changing. The FDA's fragrance page, last updated in February 2022, says the agency does not have the same legal authority to require allergen labeling for cosmetics as it has for food 1. The 2022 Modernization of Cosmetics Regulation Act (MoCRA) requires the FDA to write regulations for fragrance allergen labeling 3. When we checked in October 2026, the FDA's MoCRA page still listed that rule among those to be established, and we found no proposed rule in the Federal Register 340.
EU cosmetics fall under Regulation (EC) No 1223/2009. Its Annex III requires certain fragrance substances to be named in the ingredient list when they are present above 0.001 percent in leave-on products, such as perfume, or 0.01 percent in rinse-off products 57. That is why a European perfume box often reads "alcohol, parfum, aqua," followed by names such as linalool, limonene and citronellol.
In 2023 the European Commission extended that rule to 56 additional fragrance allergens 67. The Commission says that since July 31, 2026, cosmetics that do not meet the new labeling may no longer be placed on the EU market, and that products placed on the market before that date may still be sold until July 31, 2028 7. So for the next two years, you may find old and new labels side by side on the same shelf.
The EU rule names allergens. It does not require the rest of the fragrance formula to be listed. "Parfum" on a European label is still a single word for everything else.
Much of the world's fragrance is also made to the standards of the International Fragrance Association. IFRA's Standards ban, restrict or set specifications for individual fragrance materials 8. Following them is compulsory for IFRA's member companies, which IFRA says produce around 80 percent of the global volume of fragrance 89. IFRA calls the Standards "a self-regulating voluntary system of the industry"; they are not law, and they are revised in numbered amendments 8. The next, the 52nd, has finished public consultation; IFRA expects to publish it formally in January 2027, with new rules taking effect 11 months later for new creations and 30 months later for existing ones 10.
A perfume that follows IFRA still does not have to tell you what is in it. The houses below choose to.
This section is general information about how the US and EU rules work, as the regulators describe them. It is not legal advice.
A candle is three things: wax, wick and, in a scented candle, fragrance. The FDA treats a fragrance product as a cosmetic when it is meant to be applied to the body, and says fragrance products that are not applied to the body, such as room fresheners, are regulated by the Consumer Product Safety Commission 1. A candle sits on that side of the line, so the cosmetic ingredient rules above do not reach it.
Wax. The National Candle Association, the US industry's trade body, says paraffin, developed by removing the waxy substance from petroleum during refining, is "by far the most frequently used candle wax on a worldwide basis today." It says soy and palm waxes were developed for the candle market in the late 1990s by hydrogenating soybean and palm oils, and that beeswax is used in significantly smaller quantities 11. The association's position is that no type of wax is considered "best," and that all candle waxes, in high-quality form, "burn cleanly, safely and in the same manner" 11. That is an industry view, and we report it as one. Our interest is narrower: whether the maker tells you which wax it is.
Wick. The association lists flat, square, cored, wooden and specialty wicks, and says cored wicks most often have a core of cotton, paper, zinc or tin 12. In the United States, the Consumer Product Safety Commission has banned candlewicks with lead cores (more than 0.06 percent lead by weight in the metal) and candles made with them, for products made or imported on or after October 15, 2003 1314.
Fragrance. A candle's scent is usually described by its notes, not its formula. In Europe, a candle is treated as a chemical "mixture" under the CLP regulation. Northern Ireland's Health and Safety Executive explains that waxes themselves are not classed as hazardous but fragrance additives can be, and that the main concern is skin sensitization: a candle containing a sensitizing fragrance ingredient above set levels must name it on the label with an allergy warning 1537. That is why a European candle box may name, say, linalool or coumarin in small print. It is a safety label, not a full disclosure.
A certification worth knowing. The Nordic Swan Ecolabel, the Nordic countries' ecolabel, has criteria for candles. Its requirements include at least 90 percent renewable material, a ban on palm and soy oil, a ban on scent and perfume, and tests for soot emissions; scented or aromatherapeutic candles cannot be certified 16. A Nordic Swan candle is, by definition, an unscented one.
We will say only what the agencies say. The US Environmental Protection Agency lists burning candles among the indoor sources of particulate matter. It says the best way to reduce indoor particles is usually to reduce their sources, and notes that some, such as burning candles, may be possible to stop completely 17. It also lists air fresheners among the household products that can release organic compounds while in use and, to some degree, when stored 18.
We are not telling you to give up candles, and we make no claim that any candle here is better or worse for the air in your home; the agencies' words above are as far as we go. None of this is medical advice. If you have asthma or allergies, skin that reacts to fragrance, or you are pregnant or under a doctor's care, talk to your doctor about what is right for you and your home.
For the flame itself, follow the maker's burn instructions on each candle. The National Candle Association's own safety tips include: never leave a burning candle unattended, trim the wick to ¼ inch before each use, and keep candles at least 12 inches from anything that can catch fire 41.
Two houses that publish every material in the bottle, not only the allergens the law requires. Prices are what we saw on the date above.
One scented candle whose maker discloses all three of wax, wick and fragrance, and two unscented candles that hold certifications we found on the certifiers' records. The last is our one better-value pick.
The famous names, and what they tell you
We looked at the candles from the most celebrated houses first. Here is what their own product pages disclose, as we read them on October 19, 2026. None of this is a judgment of how they smell or burn; it is only what the maker tells you. A house that does not name its wax or wick on the page is not, for that reason, any less safe or well made; not disclosing is not a finding about safety or quality.
- Diptyque says each candle is made from "a blend of several types of wax and a high-quality fragrance concentrate." Its product page does not name the waxes or the wick material 31.
- Trudon, the historic French candlemaker, says its wicks "are made of cotton" and each glass is hand-crafted in Tuscany. It describes its wax only as formulas that are "the fruit of specific developments" and does not name the wax 32.
- Le Labo describes "a custom blend of waxes" and "wicks constructed with natural fibers." Its EU safety notice names some fragrance components 33; EU hazard labeling requires sensitizing substances above set levels to be named 1537.
- Byredo's candle page gives notes and burn time but does not name the wax or the wick material 38.
- Maison Louis Marie lists "Soy Wax Blend, Fragrance" as the ingredients of its No. 04 Bois de Balincourt candle, and does not name the wick material 34.
- Boy Smells says its reformulated wax is vegan and non-GMO, "made with US farmed soy blend." Its product page does not name the wick material 35.
- Otherland names its wax (a coconut and soy blend) and describes its wick as 100 percent lead-free cotton; it describes its fragrance by notes 36.
If wax, wick and fragrance matter to you, these are the questions to ask at the counter, or by email before you buy.
The short version
- In the US, "fragrance" on a cosmetic label can stand for an undisclosed mixture, because the FDA regards fragrance formulas as the components most likely to be trade secrets 12. MoCRA requires the FDA to write fragrance allergen labeling rules; we found none proposed as of October 2026 340.
- In the EU, named fragrance allergens must appear on the label above set levels, and 56 more apply to products placed on the market since July 31, 2026 57. "Parfum" still covers the rest.
- IFRA's Standards bind its members but do not require disclosure 89.
- A candle's label is not a cosmetic label. Ask for the wax, the wick and the fragrance; in the US, candles with lead-core wicks made or imported on or after October 15, 2003 are banned 1314.
- The EPA lists candles among indoor sources of particles, and says reducing sources is usually the best way to reduce them 17.
- Three picks hold a certification we found on the certifier's own records: Henry Rose Jake's House (EWG Verified) 21, HAY's Column Candle (Nordic Swan Ecolabel) 26 and Fontana (MADE SAFE) 29. Henry Rose and Heretic publish full ingredient lists; every claim about them is the maker's own.
- Never leave a burning candle unattended, and trim the wick before each use, as the National Candle Association advises 41.
- If you have asthma, allergies or skin that reacts to fragrance, or you are pregnant or under a doctor's care, talk to your doctor before bringing a new scent into your routine or your home.
- This is general information, not medical or legal advice.
