5 Toxic Chemicals Hiding in Your All-Purpose Cleaner (And What to Use Instead)

By The Seaside Naturals Team · June 2026 · 6 min read

Most all-purpose cleaners you pick up at the grocery store contain chemicals linked to asthma, hormone disruption, and respiratory damage. The problem is rarely obvious: ingredients can appear under vague terms like "fragrance" or "solvent blend," and a label that says "cuts through grease" tells you nothing about what the product leaves behind in the air your family breathes.

A 2023 Environmental Working Group analysis identified 530 unique volatile organic compounds (VOCs) across just 30 common cleaning products, with 193 classified as hazardous. Indoor air can be two to five times more polluted than outdoor air when these products are in regular use, according to the American Lung Association.

Below are the five chemicals most commonly hiding in all-purpose cleaners, what the research says about each one, and the plant-based swap that removes all of them from your home in one step.

1. What Is 2-Butoxyethanol, and Why Is It in Your Cleaner?

2-Butoxyethanol is a glycol ether used to boost the grease-cutting power of all-purpose sprays. It is one of the most common solvents in conventional household cleaners, and it does not have to be listed by name: watch for labels that say "glycol ethers" or "solvent blend."

The US Occupational Safety and Health Administration (OSHA) classifies it as a hazardous substance. At occupational exposures it is linked to blood and kidney damage. At lower, household-level exposure it irritates the respiratory tract, eyes, and skin. The concern is cumulative: a quick spray of kitchen counter once a day, every day, adds up over months and years.

2. What Does "Fragrance" Actually Mean on a Cleaner Label?

"Fragrance" is a legally protected catch-all term that can cover dozens of undisclosed chemicals in a single ingredient listing. Phthalates are among the most common, added to help scent linger on surfaces. They are well-documented endocrine disruptors: the US National Toxicology Program has linked certain phthalates to developmental and reproductive effects.

A product marketed as "fresh linen scent" or "mountain breeze" can legally contain phthalates without listing them. The only way to be certain they are absent is to buy from a brand that discloses every ingredient by name, or that is certified fragrance-free by a credible third party.

Are Quaternary Ammonium Compounds (Quats) Safe for Everyday Home Use?

Quats appear in "antibacterial" and "disinfecting" all-purpose sprays under names like alkyl dimethyl benzyl ammonium chloride or benzalkonium chloride. Research published in Environmental Health Perspectives has linked chronic quat exposure to asthma development and respiratory inflammation. Separate studies have raised concerns about effects on reproductive health and the emergence of antibiotic-resistant bacteria.

For everyday household cleaning, as opposed to clinical disinfection, quats offer no meaningful benefit over a well-formulated plant-based cleaner. A kitchen counter, bathroom sink, or stovetop does not need a pharmaceutical-grade disinfectant. It needs a surfactant that lifts grime and a formula that rinses clean without leaving behind a chemical residue.

How Dangerous Is Ammonia in All-Purpose Cleaners?

Ammonia is a common solvent in all-purpose and glass cleaners. It irritates the eyes, nose, and throat on contact. For people with asthma, it can trigger attacks even at the low concentrations found in a typical kitchen spray. The American Lung Association specifically recommends avoiding cleaners with ammonia.

There is also a mixing risk that most people are unaware of: ammonia combined with bleach (another product commonly stored under the same sink) produces chloramine gas, which is toxic even in small amounts. This is not an edge case. It happens in homes every year.

Ammonia evaporates quickly, which is why a freshly cleaned window stops smelling sharp within minutes. That quick evaporation does not eliminate the exposure. It means the chemical was inhaled during application and cleaning.

What Are Formaldehyde-Releasing Preservatives, and Are They in My Cleaner?

Preservatives like DMDM hydantoin and quaternium-15 are added to water-based cleaners to prevent bacterial growth in the bottle. They work by slowly releasing formaldehyde over time. Formaldehyde is classified as a known human carcinogen by the International Agency for Research on Cancer (IARC).

These ingredients never appear on a label as "formaldehyde." They appear under their technical names, buried near the end of the ingredient list. Most consumers have no way of connecting the dots without looking them up.

What to Use Instead: A Plant-Based All-Purpose Cleaner That Lists Every Ingredient

The most direct swap is a cleaner that derives its cleaning power from plant-based surfactants and essential oils, lists every ingredient by name, and contains no synthetic fragrance, glycol ethers, quats, ammonia, or preservatives of concern.

Seaside Naturals On Purpose Concentrate is formulated exactly this way. Each small concentrate bottle mixes with water to make a full 16 oz spray bottle of all-purpose cleaner. No glycol ethers. No quats. No synthetic fragrance. The scent comes from essential oils, listed by name on the label.

Frequently Asked Questions

Do plant-based cleaners actually clean as well as conventional ones?

Yes, for the vast majority of everyday household cleaning tasks. Plant-based surfactants break down oils and lift dirt from surfaces the same way petroleum-derived surfactants do. The key difference is what is left behind in the air and on the surface afterward. Research from the EWG found that green cleaning products emitted roughly 4 hazardous chemicals on average, compared to 22 in conventional formulas.

How do I find out what is in my current cleaner?

Look up your product in the EWG Healthy Cleaning Guide. Products are graded A through F. Anything rated D or F contains ingredients the EWG considers high concern. You can also search individual ingredient names in the EWG's ingredient database to see what research exists on each one.

Is "natural" or "plant-based" on a label a guarantee the product is safe?

No. Neither term is regulated, and both can be placed on a label without third-party verification. The only reliable signals are a full, plain-language ingredient list, an EWG A or B rating, or a certification like Made Safe or EPA Safer Choice. A genuinely clean formula will not hide anything under "fragrance" or "proprietary blend."

Are concentrate formats as effective as ready-to-use sprays?

Yes. Concentrates are formulated at a higher active-ingredient ratio and deliver the same cleaning performance once diluted correctly. The advantage for you is less plastic packaging, less water shipped per use, and a lower cost per bottle: Seaside Naturals concentrates work out to $6 per finished bottle or less when buying the 4 oz size.

My family member has asthma. Which chemicals should I avoid first?

Quats, ammonia, and synthetic fragrances are the three most common cleaning-product triggers for asthma and chemical sensitivities. The American Lung Association recommends avoiding all products with added fragrance and choosing fragrance-free or plant-based alternatives where possible. Switching to an unfragranced or essential-oil-scented plant-based cleaner removes all three categories at once.

What should I do with conventional cleaners I already have?

Do not pour them down the drain. Most municipalities have household hazardous waste drop-off programs that accept cleaning products. Search "[your city] household hazardous waste disposal" to find your nearest site. Once you have disposed of them safely, a plant-based concentrate is a straightforward replacement going forward.
