Volatile chemicals in consumer products such as air fresheners, laundry detergents, fabric softeners, and dryer sheets may be hazardous.
Throw Household Products Off the Scent,

In addition to meat, exposure to common household chemicals may exacerbate or induce allergies, asthma and eczema. Researchers at Harvard and all around the world collected air samples from where children slept and demonstrated for the first time that the bedroom concentration of propylene glycol and glycol ethers was significantly associated with an elevated risk of multiple allergic symptoms, runny nose, and eczema. This class of chemical compounds is found in cleaning fluids, paint, pesticides, PVC pipes and varnishes, and may be one of the reasons we’ve seen an increase in these kinds of disease around the world over the last few decades.
Recently, researchers put a few consumer products to the test: air fresheners, a laundry detergent, fabric softener, and dryer sheets, each with annual sales over $100 million dollars. Six products; nearly a hundred volatile chemicals identified, though none were listed on the labels, it usually just says something like fragrance. And ten of the chemicals they found are regulated as toxic or hazardous, with three officially classified as hazardous air pollutants.
For example, the fabric softener they tested. On the label it just says biodegradable fabric softening agents. And it even smells like mom when she leans in for a good-night kiss. But this is what they really found: a very long list of hazardous chemicals, including the carcinogenic hazardous air pollutant acetaldehyde.
What about if you just stick to the naturally scented products? Even products advertised as green, natural, or organic emitted as many hazardous chemicals as standard ones. For example a soap boasting pure essential oils and organic tea infusions also contained all of these.
Yeah but what if you somehow know for certain it’s all just natural— like the limonene, that’s a real phytochemical found in real citrus. Until, it photo-oxidizes with ozone in ambient air to form dangerous secondary pollutants, including formaldehyde.
When it comes to consumer products, the best smell is no smell.
