Catching the scent of laundry detergent, or a quick sniff of the bottle, is not considered harmful for most people. What matters is how you react and how much you breathe in. Some people are sensitive to fragrance: in a national survey published in 2016, 34.7% of U.S. adults reported health problems from fragranced consumer products, and 12.5% reported problems from laundry product scents vented from dryers. Deliberately inhaling concentrated detergent or powder up close is a different matter and is best avoided. If a scent bothers you, switch to fragrance-free products, and call Poison Help at 1-800-222-1222 if someone swallows detergent or has trouble breathing after exposure.

Where the smell comes from

Most of what you smell is added fragrance. Tide’s public ingredient list, for example, describes “fragrance, perfume” as providing freshness. Unilever’s ingredient list for Persil Biological names several individual fragrance ingredients, including linalool, geraniol and citronellol, alongside a general “parfum.”

How much companies have to tell you depends on where you live. California’s Cleaning Product Right to Know Act of 2017 requires cleaning products sold in the state to disclose certain fragrance allergens on the label and online when they are present above 0.01 percent, with online disclosure phased in first and label disclosure a year later. Many brands now publish ingredient lists online for all U.S. shoppers.

What the research says

Self-reported effects. Researcher Anne Steinemann surveyed 1,136 U.S. adults in a study published in 2016 in Air Quality, Atmosphere & Health. Results:

Finding	Share of respondents
Reported health problems from fragranced consumer products	34.7%
Reported problems from laundry scents vented from dryer vents	12.5%
Exposed to fragranced laundry products at least weekly	84.1%

These are self-reports. The survey shows how many people say they react, not what caused each reaction. An earlier survey cited in the paper found 10.9% reporting problems from dryer-vent scents in 2005–06.

Dryer vent emissions. A 2011 University of Washington study led by Steinemann sampled air from the dryer vents of two homes after washing and drying with a top-selling scented liquid detergent and scented dryer sheet. The team reported more than 25 volatile organic compounds, including seven hazardous air pollutants, two of which (acetaldehyde and benzene) are classified by the U.S. EPA as carcinogens.

What manufacturers said

The American Cleaning Institute and three other industry groups rejected the 2011 study’s conclusions. They called the dataset too small, said the design had confounding factors and too few controls, and pointed out that the highest concentrations of four of the seven hazardous air pollutants were found when no laundry products were used. They also said benzene is not used in fragranced products and that fragranced fabric care products are safe when used as directed. The study and the rebuttal disagree, and the two-home sample is small, so neither settles the question.

Who should be careful

People who notice symptoms. If a scent gives you a headache, makes you cough, or worsens asthma, that is a reason to avoid it, whatever the cause.
People with eczema or sensitive skin. The American Academy of Pediatrics (AAP) advises mild, fragrance-free laundry detergents for children with eczema.
Babies. Whirlpool recommends a gentle, preferably fragrance-free detergent for baby clothes. See what washer setting for baby clothes.
Anyone sniffing concentrated product on purpose. Breathing powder dust or putting your face over an open container is not how detergent is meant to be used. If you find yourself craving the smell, read why do I crave the smell of laundry detergent and consider talking to a doctor.

How to cut down on laundry scent

Choose fragrance-free products. The U.S. EPA’s Safer Choice program offers a Fragrance-Free label for products that meet its Safer Choice standard and have been verified to be free of fragrance materials.
Read the label carefully. “Unscented” and “fragrance-free” are not always the same thing. Look for the ingredient list, which many brands publish online.
Use the right amount. GE Appliances warns that too much detergent can lead to over-sudsing and residue left on clothes.
Skip extra scent products. Scent boosters, scented softeners and dryer sheets all add fragrance. See are scent beads bad for washers.
Ventilate. Keep the laundry area aired out, and make sure the dryer vents outdoors.

If someone is exposed

If someone swallows detergent, gets it in their eyes, or has trouble breathing after exposure, call the Poison Help line at 1-800-222-1222. Call 911 for severe symptoms such as serious breathing problems.
