How to Read a Cleaning Product Label (and What They're Hiding)

By Kristina Braly, MD — Founder, AEMBR

Most people spend more time reading a nutrition label on a granola bar than they do reading the ingredient list on the cleaning spray they use on their kitchen counter every single day. I was one of those people — until I started formulating my own products and realized how much the conventional cleaning industry relies on labeling gaps, chemical name obscurity, and consumer unfamiliarity to keep ingredient lists effectively unreadable. As a physician, I have some background in chemistry and toxicology. Even I found it harder than it should be to decode what was actually in the bottle. This guide is the one I wish had existed when I started.

Why Cleaning Product Labels Are So Hard to Read

The short answer: unlike food, cleaning products are not required by law to disclose a complete ingredient list. The FDA regulates personal care products and food. The EPA regulates pesticides and disinfectants (to a degree). But for general household cleaners — your dish soap, your laundry detergent, your countertop spray — there is no federal requirement to list every ingredient on the label.

Some brands voluntarily disclose. Many don't. Some disclose partial lists. The result is that consumers are reading labels that were never designed to be informative — they were designed to satisfy the minimum legal requirement while protecting proprietary formulas. That's not a conspiracy theory; it's a regulatory gap.

The California Cleaning Product Right to Know Act (effective 2020) is the closest thing the US has to a national standard, and it still allows fragrance ingredients to be listed simply as "fragrance." Understanding that gap — and the tricks that fill it — is the first step.

The "Fragrance" Loophole

"Fragrance" — or its synonym "parfum" — is the most consequential two-word gap in consumer labeling. When you see it on a cleaning product ingredient list, you are looking at a single listed ingredient that could represent anywhere from a handful to hundreds of distinct chemical compounds, none of which need to be individually disclosed.

Why? Because fragrance formulas are classified as trade secrets under federal law. The Fair Packaging and Labeling Act (FPLA) allows manufacturers to list the entire fragrance blend as a single ingredient. This is the legal mechanism that permits phthalates — a class of chemicals linked to endocrine disruption in reproductive toxicology literature — to remain hidden inside cleaning product fragrance blends with no labeling requirement.

I covered phthalates and their specific mechanisms in our post on phthalate-free laundry detergent. The short version here: if a product lists "fragrance" and does not independently state "phthalate-free," you cannot assume the fragrance blend is phthalate-free.

What to look for instead: voluntary fragrance disclosure programs, IFRA (International Fragrance Association) compliance statements, or explicit "phthalate-free fragrance" language. AEMBR fragrance oils are vetted to IFRA standards and are phthalate-free — that's a formulation choice, not a legal requirement, and it has to be stated explicitly to mean anything.

The "Preservative" Catch-All

After "fragrance," the next most common opacity on a cleaning label is "preservative" — sometimes listed individually, sometimes bundled into a catch-all term. Preservatives are necessary in aqueous (water-based) cleaning formulas to prevent microbial growth. That part is legitimate. The issue is which preservative.

Some preservative classes have concerning safety profiles at certain concentrations:

• Formaldehyde-releasing preservatives (DMDM hydantoin, imidazolidinyl urea, quaternium-15): these release small amounts of formaldehyde over time in aqueous solution. Formaldehyde is classified as a Group 1 human carcinogen by IARC. The concentrations in consumer products are debated, but I don't use them in my formulas — period.
• Methylisothiazolinone (MIT) and benzisothiazolinone (BIT): effective biocides, but MIT in particular has been linked to contact sensitization and allergic reactions at concentrations as low as 15 ppm in some studies. The EU has restricted MIT in rinse-off products and is tightening limits on leave-on applications.
• Parabens (methylparaben, propylparaben, butylparaben): estrogen-mimicking activity in vitro; the evidence on human health significance at consumer-product doses is genuinely contested in the literature, but the precautionary principle has led most clean formulation brands to avoid them.

None of these being listed as simply "preservative" — with no further identification — is acceptable if you want to make informed choices. Look for specific preservative names. Cross-reference with the EWG Skin Deep database, which covers cleaning product ingredients as well.

Surfactant Naming: The Same Molecule, Twelve Names

Surfactants — the cleaning agents that lift grease and soil — are among the most important ingredients in any cleaning formula, and among the most confusingly named. A single surfactant compound can appear under multiple synonymous names depending on the manufacturer and labeling convention used.

Sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) are the canonical examples. They are related but distinct compounds — SLS is more irritating to skin and mucous membranes; SLES is milder but can be contaminated with 1,4-dioxane (a probable human carcinogen per the EPA) as a by-product of the ethoxylation manufacturing process. You'll see them listed as:

• Sodium lauryl sulfate / SLS / sodium dodecyl sulfate
• Sodium laureth sulfate / SLES / sodium lauryl ether sulfate / sodium polyoxyethylene lauryl sulfate

This isn't inherently deceptive — INCI (International Nomenclature of Cosmetic Ingredients) and chemical naming conventions have legitimate variation — but it means a consumer comparing two products may not realize they're looking at the same ingredient under different names.

For our AEMBR Laundry Powder, we use plant-derived surfactants. I made that choice after reviewing the safety literature on conventional sulfates and deciding that, given a clean alternative existed with comparable performance, there was no reason to include them. If you want a deeper breakdown of what's in conventional laundry detergent, our physician's ingredient breakdown post covers this in full.

pH: The Unlisted Ingredient That Tells You a Lot

pH isn't typically listed on a cleaning product label, but it's one of the most informative things you can know about a formula — and you can test it at home with a $6 pH strip kit.

pH determines cleaning mechanism. Highly alkaline formulas (pH 10–14) are effective on grease and organic soils but can be harsh on surfaces, skin, and respiratory mucosa. Highly acidic formulas (pH 1–4) cut through mineral deposits and limescale but can damage sealing, grout, and skin. Most effective multi-surface cleaners work in the pH 7–9 range — mildly alkaline.

If a label says "powerful degreaser" but doesn't tell you the pH or the surfactant system, that's a gap. The mechanism of cleaning matters for safety evaluation, not just the marketing claim.

Concentration: Why "Contains X" Is Meaningless

Ingredient lists in the US are typically listed in descending order of concentration — but not always, and there's no requirement to disclose the actual percentage of each ingredient. This matters because a cleaning product can truthfully say "contains plant-derived surfactants" while those surfactants represent 0.5% of the formula and the remainder is water, conventional solvents, and synthetic fragrance.

Conversely, a product can list an ingredient that sounds alarming (like an acid) that represents a trace stabilizing amount with no practical exposure significance.

This is why full ingredient disclosure combined with concentration ranges is the meaningful standard — and why I publish AEMBR's ingredient lists in full. The claim "plant-derived" means nothing if you don't know what proportion of the formula it represents. See also our post on whether clean cleaning products are actually effective for the performance side of this question.

The EWG Database: How to Use It Properly

The EWG Guide to Healthy Cleaning is the most accessible consumer-facing tool for cross-referencing cleaning product ingredients. Products are rated A through F based on ingredient hazard scores, disclosure level, and data availability.

A few things to understand about using it well:

• Hazard ≠ risk. EWG scores are based on ingredient hazard profiles — the intrinsic toxicological properties of a compound — not necessarily the risk at the concentration used in a specific product. A compound that is hazardous at high concentrations may be safe at 0.1%. EWG is a useful starting screen, not a definitive safety ruling.
• Disclosure credit matters. Products that fully disclose ingredients get credit for it in EWG's scoring, even if some ingredients have moderate hazard profiles. A product with full disclosure and some moderate-score ingredients may rate better than a product with no disclosure at all.
• Not all products are in the database. If a product isn't listed, you can search by ingredient using the Skin Deep database. The EWG Verified program (a separate certification) requires full ingredient disclosure, no EWG chemicals of concern, and third-party verification.

What "EPA Safer Choice" Actually Certifies

The EPA Safer Choice program is a federal certification that requires every ingredient in a product to meet EPA's safety standards for human health and environmental impact — including fragrance ingredients. This is different from most labeling claims because it requires third-party review of the actual formula, not just self-attestation.

EPA Safer Choice does not mean "perfect" or "zero risk" — it means the ingredient profile has passed federal scrutiny against safety benchmarks. It's one of the more meaningful third-party signals on a cleaning product label, and one of the most under-recognized by consumers.

Leaping Bunny (cruelty-free) and MADE SAFE are other third-party certifications worth recognizing. None of them are interchangeable — each certifies for different attributes. A product can be Leaping Bunny certified (no animal testing) while still containing phthalates. Read what each certification actually requires.

The Quick Label Audit: A 60-Second Check

Here's the practical checklist I use when I'm evaluating a new cleaning product:

Terms That Mean Nothing (Legally)

These terms appear constantly on cleaning product marketing and have no legal definition under US federal law:

• "Natural" — not defined or regulated for cleaning products
• "Non-toxic" — not a regulated term; every cleaning product has some toxicity threshold
• "Eco-friendly" / "environmentally safe" — unregulated; the FTC's Green Guides provide guidance but are not enforced uniformly
• "Gentle" / "mild" — no standard definition
• "Free of harsh chemicals" — vague and self-defined
• "Plant-based" — no minimum plant-derived content requirement

This doesn't mean every product using these terms is deceptive — it means these terms require verification, not trust. Pair any marketing claim with an actual ingredient list before accepting it at face value.

What Genuine Transparency Looks Like

Full ingredient disclosure means every ingredient by INCI or CAS name, in descending concentration order, with fragrance components named individually (or at minimum with a "phthalate-free" attestation backed by testing). Concentration ranges are an additional transparency step. Third-party certification of the formula — not just the claims — is the highest standard currently available.

This is the standard I built AEMBR's cleaning products to. The AEMBR Laundry Care collection publishes full ingredient lists. If a compound isn't named, it isn't in the formula. That's not common in this category — it should be.

If you want to audit any product outside AEMBR, the EWG database, EPA Safer Choice directory, and MADE SAFE certification list are the three most reliable third-party resources. Start with the label. Then verify.

Frequently Asked Questions

Are cleaning product companies required to list all ingredients?

No. Unlike food, general household cleaning products are not federally required to disclose a complete ingredient list. Some state laws (notably California's Cleaning Product Right to Know Act) require more disclosure, but fragrance ingredients remain shielded as trade secrets under federal law.

What does "fragrance-free" mean on a cleaning label?

Fragrance-free means no fragrance compounds were added — not even masking fragrances. This is different from "unscented," which may contain masking fragrance to cover raw material odors. For a full breakdown, see our fragrance-free labeling explainer.

How can I check if a cleaning product is safe?

The EWG Guide to Healthy Cleaning and EPA Safer Choice directory are the two most accessible tools. Cross-reference the ingredient list — not just the marketing claims — against these databases for specific compounds of concern.

What is 1,4-dioxane and should I be concerned?

1,4-dioxane is a probable human carcinogen (EPA classification) that forms as a by-product of the ethoxylation process used to produce certain surfactants (notably SLES). It is not added intentionally and does not appear on ingredient labels — it's a manufacturing contaminant. Choosing surfactant systems that do not require ethoxylation (like glucoside-based surfactants) avoids this contaminant entirely.

The Bottom Line

Reading a cleaning product label is a skill, not an instinct — and the industry has historically not made it easy. The fragrance loophole, non-specific preservative listings, surfactant name variation, and absence of concentration data are all real barriers to informed purchasing. They're not all intentional deception, but they produce the same result: a consumer who can't tell what they're buying.

Use the checklist in this post as your starting audit. Cross-reference with EWG and EPA Safer Choice. Ask specifically about fragrance composition and preservative identity when full disclosure isn't offered. And favor brands that publish full ingredient lists voluntarily — because that's the only standard that actually tells you what's in the bottle.
