Bath & Body Works products are not acutely toxic, but they do contain several categories of chemicals that raise legitimate health concerns with regular use. The biggest issues center on undisclosed fragrance chemicals, emissions from scented candles and plug-in air fresheners, and preservatives that slowly release formaldehyde. None of these are likely to cause immediate harm, but the cumulative exposure from daily use of multiple products adds up in ways worth understanding.
What “Fragrance” Actually Means on the Label
The single word “fragrance” on a Bath & Body Works label can represent a mixture of hundreds of individual chemicals. Under U.S. law, companies are allowed to list fragrance as one ingredient without disclosing what’s actually in it, because fragrance formulas are considered trade secrets. Bath & Body Works states that all its fragrances comply with standards set by the International Fragrance Association (IFRA) and the Research Institute for Fragrance Materials (RIFM), but the company does not publicly list the individual chemicals that make up each scent.
This matters because fragrance mixtures are one of the most common sources of volatile organic compounds (VOCs) in consumer products. Research from the University of Washington analyzed scented products using gas chromatography and found that a single product emitted an average of 17 different VOCs. Each product released between one and eight chemicals classified as toxic or hazardous, and close to half of the products tested generated at least one carcinogenic air pollutant, including acetaldehyde, formaldehyde, 1,4-dioxane, or methylene chloride. Without full ingredient disclosure, there’s no way for consumers to know exactly which of these compounds are present in a given Bath & Body Works product.
Scented Candles and Indoor Air Quality
Bath & Body Works is one of the largest candle retailers in the country, and candle emissions are a well-documented source of indoor air pollution. The concern depends partly on what the candle is made of. Paraffin wax, a petroleum byproduct commonly used in mass-market candles, releases higher levels of harmful compounds than plant-based alternatives like soy or beeswax. When paraffin candles burn, they can emit formaldehyde, toluene, and benzopyrene in measurable quantities.
Candle fumes also contain polycyclic aromatic hydrocarbons (PAHs), a class of compounds that includes several known carcinogens: naphthalene, anthracene, and pyrene among them. These come from the combustion of the wax itself, the fragrance oils, and any dyes used to color the candle. Studies in environmental test chambers have measured elevated levels of carbon monoxide, carbon dioxide, formaldehyde, and other VOCs in rooms where scented candles were burning, confirming that candles meaningfully contribute to indoor pollution.
The dose matters here. Lighting a candle once in a while in a well-ventilated room is very different from burning multiple candles daily in a small, closed space. If you burn candles frequently, choosing ones made from soy or beeswax and scented with essential oils rather than synthetic fragrance reduces your exposure. Trimming the wick to about a quarter inch also cuts down on soot and incomplete combustion.
Wallflowers and Plug-In Air Fresheners
Bath & Body Works Wallflowers, the brand’s plug-in scent diffusers, work by continuously heating fragrance oil and dispersing it into the air. Unlike a candle you blow out, these devices run around the clock, creating constant low-level VOC exposure in whatever room they’re in.
One especially relevant chemical reaction involves limonene, a citrus-scented compound that is one of the most commonly detected VOCs in fragranced products. Limonene itself isn’t particularly dangerous, but when it meets ozone already present in indoor air, the two react to form formaldehyde and other secondary pollutants. This means the actual chemicals you breathe aren’t limited to what’s in the product. New compounds form in the air itself. In rooms with poor ventilation, these secondary pollutants can build up to levels well above background concentrations.
Petroleum-derived chemicals make up an estimated 95% of the compounds used in synthetic fragrances. Some of these include benzene derivatives and benzidine-based dyes, which have been linked to bladder cancer in occupational exposure studies. The concentrations in a home setting are far lower than in industrial environments, but continuous daily exposure over years is a different calculation than brief occasional contact.
Formaldehyde-Releasing Preservatives in Lotions and Soaps
Bath & Body Works has confirmed that while it does not add formaldehyde directly to its products, its personal care items “may contain low levels of formaldehyde-releasing preservatives.” The two most common ones in their products are DMDM hydantoin and diazolidinyl urea. Both appear on ingredient labels by name.
These preservatives work by slowly releasing small amounts of formaldehyde over time, which kills bacteria and extends shelf life. Formaldehyde is a known human carcinogen at higher exposure levels, though the amounts released by a single lotion application are extremely small. The concern is cumulative: if you use a body wash, lotion, and hand soap from Bath & Body Works every day, you’re getting repeated low-level formaldehyde exposure through multiple products. People with sensitive skin or conditions like eczema are more likely to react to these preservatives with contact dermatitis, redness, or itching.
If you want to avoid these ingredients, check the label for DMDM hydantoin and diazolidinyl urea specifically. They’re listed in the ingredient panel on every product.
Who Should Be Most Cautious
The risks from Bath & Body Works products aren’t equal for everyone. People with asthma or other respiratory conditions are more vulnerable to the VOCs emitted by candles and plug-in fresheners. Those with sensitive skin or fragrance allergies are more likely to react to the preservatives and undisclosed fragrance chemicals in body care products. Young children breathe faster relative to their body size, which means they inhale proportionally more airborne pollutants in a scented room.
Pregnant women may also want to limit exposure. Several of the VOCs commonly found in fragranced products, including formaldehyde and toluene, are on regulatory watch lists for developmental toxicity, even at low concentrations.
Reducing Your Exposure Without Giving Everything Up
You don’t necessarily need to throw out every Bath & Body Works product you own, but a few changes can meaningfully cut your chemical exposure. Switching from paraffin candles to soy or beeswax options eliminates the worst combustion byproducts. Opening a window while burning any scented candle helps clear VOCs before they accumulate. Replacing Wallflowers with occasional candle use, rather than continuous plug-in diffusion, reduces your baseline exposure from hours of constant output to shorter, controlled periods.
For body care products, reading the ingredient list takes about 30 seconds and tells you whether DMDM hydantoin or diazolidinyl urea is present. Choosing “fragrance-free” products (not “unscented,” which can still contain masking fragrances) is the most reliable way to avoid the undisclosed chemical mixtures hiding behind the word “fragrance.” If you love a particular scented lotion, using it occasionally rather than as a daily staple is a simple way to keep exposure low.
