How to Read a Cleaning Product Label in 60 Seconds (Founder Walkthrough)
Italo Campilii walks you through exactly how to decode a cleaning product ingredient label—fast, specific, no chemistry degree required.
A label that hides its ingredients isn't being modest—it's making a choice about what you don't know.
— Italo Campilii, Ecolosophy Co-Founder
Picture this: you’re standing in the cleaning aisle at Target, bottle in hand, trying to figure out if the lavender-scented “plant-powered” all-purpose spray is actually safe to use around your toddler and your immunocompromised mother-in-law. The front label says “99% naturally derived.” The back label lists 22 ingredients, half of which look like a crossword puzzle clue. You have about 45 seconds before your patience runs out. I’ve been there — except my stakes were personal. After years managing Crohn’s disease, I learned the hard way that what I absorbed through my skin, lungs, and gut during cleaning sessions genuinely moved the needle on my inflammation. So I built a 60-second system. Here it is, exactly.
Step 1 (0–15 Seconds): Flip It Over and Find the Ingredient List
The front of any cleaning product bottle is an advertisement. The back is the evidence. Your first move is always to flip it.
If there is no ingredient list at all, that’s already critical information. Unlike food and drugs, cleaning products in the US have no federal law mandating full ingredient disclosure. Some brands voluntarily disclose; many don’t. California’s Cleaning Product Right to Know Act (effective 2020) requires disclosure on manufacturer websites for products sold in California, but shelf labels still vary enormously. The EPA Safer Choice program goes furthest, requiring ingredient disclosure down to 0.01% concentration — but most products on the shelf don’t carry that certification.
If you see a full ingredient list: good. If you see only “active ingredients” or nothing at all: proceed with skepticism. A brand that’s proud of its formula will show you the formula.
How Ingredients Are Listed (and Why Order Matters)
When an ingredient list does exist, ingredients are typically listed in descending order by concentration — the same convention used in cosmetics under INCI (International Nomenclature of Cosmetic Ingredients) standards. That means the first three to five ingredients make up the bulk of the product. For most liquid cleaners, you’ll see water (aqua) first, then a surfactant, then a solubilizer or chelating agent. The further down the list an ingredient appears, the smaller its concentration — but that doesn’t mean it’s harmless. Preservatives like methylisothiazolinone (MI) appear near the bottom of a label at concentrations well under 1%, yet NIH research has linked MI to allergic contact dermatitis at concentrations as low as 15 parts per million.
Step 2 (15–35 Seconds): Find the Five Red-Flag Words
Scan the ingredient list for these five terms specifically. You don’t need to read every word — just grep for these.
| Term to Scan For | What It Signals | What to Do |
|---|---|---|
| Fragrance / Parfum | Up to 3,500 undisclosed chemicals under trade-secret rules | Search the brand’s SmartLabel or SDS sheet for specifics |
| Methylisothiazolinone (MI) or Benzisothiazolinone (BIT) | Preservatives linked to skin sensitization and aquatic toxicity | Cross-reference on EWG; consider if you have sensitive skin |
| Sodium Hypochlorite | Bleach; reacts with ammonia-based products to form chloramine gas | Never mix; ensure adequate ventilation |
| Quaternary Ammonium Compounds (“Quats”) | Disinfectants linked to asthma and reproductive concerns in repeated exposure | Look for specific names: benzalkonium chloride, didecyl dimethyl ammonium chloride |
| PEG compounds (PEG-6, PEG-40, etc.) | May be contaminated with 1,4-dioxane, a probable carcinogen | Check EWG score; prefer products third-party tested for dioxane |
The biggest single red flag is “fragrance.” The FDA acknowledges that fragrance formulas are protected as trade secrets, meaning a company can list a single word — “fragrance” — to cover a blend of dozens or hundreds of chemical compounds. Some of those compounds are benign. Some are classified as allergens, hormone disruptors, or volatile organic compounds (VOCs) that degrade indoor air quality. You cannot know which without more disclosure. If a brand isn’t telling you what’s in their fragrance, that’s a choice they made.
This is exactly why Elizabeth Uria, PhD — our co-founder and formulator — made the decision to list every ingredient in our products by full INCI name, including what makes up our scent profiles. It’s not a marketing move. It’s a baseline of respect.
Step 3 (35–50 Seconds): Check for Certifications (and Know What They Actually Mean)
Not all certification logos are equal. Here’s a fast reference:
| Certification | Who Grants It | What It Actually Requires |
|---|---|---|
| EPA Safer Choice | U.S. Environmental Protection Agency | Full ingredient review; biodegradability per OECD 301F; no carcinogens, reproductive toxins, or persistent pollutants |
| EWG Verified | Environmental Working Group | Meets EWG’s strictest standards for ingredient transparency and hazard; no EWG “red list” ingredients |
| USDA Certified Biobased | U.S. Dept. of Agriculture | Measures % biobased carbon content only — says nothing about safety |
| ”Natural” / “Green” / “Plant-Based” | Nobody — unregulated | No legal definition; purely marketing language |
| California Prop 65 Warning | California OEHHA | Product contains ≥1 chemical from the 900+ Prop 65 list of carcinogens or reproductive toxins |
A Prop 65 warning, in particular, deserves a double-take. It doesn’t mean the product is illegal, but it does mean California has determined there’s enough evidence to require consumer notification. Seeing that warning on a cleaning product should prompt you to dig one level deeper — which specific chemical triggered the warning, and at what exposure level?
For a deeper look at how ingredient transparency varies across popular brands, the piece on hidden toxins in cleaning products walks through specific product comparisons by category.
Step 4 (50–60 Seconds): One Quick Cross-Reference
You’ve found an ingredient you don’t recognize. You have 10 seconds. Here’s the fastest path:
- Copy or photograph the INCI name (e.g., “cocamidopropyl betaine”).
- Go to ewg.org/guides/cleaners or EWG Skin Deep.
- Search the ingredient name. EWG will return a hazard score from 1 (low concern) to 10 (high concern) with the specific concerns flagged — allergy, cancer, developmental toxicity, environmental persistence.
That’s it. One cross-reference in 10 seconds tells you more than reading the entire marketing copy on the front of the bottle. If you want to understand more about why surfactant sourcing specifically matters — and why “plant-based” surfactants are not all created equal — the surfactant distinction article goes deep on that.
What Good Transparency Actually Looks Like
A brand that’s done the work will give you: a complete INCI ingredient list on the bottle, a reason for each ingredient in accessible language somewhere on their site, a clear statement about fragrance components, and a third-party certification that verifies what they’re claiming. Anything short of that is asking you to trust them without evidence. Real non-toxic cleaners that work tend to have this documentation — because the formula holds up to scrutiny.
The 60-Second Checklist, Summarized
| Second | Action |
|---|---|
| 0–15 | Flip the bottle. Is there a full ingredient list? |
| 15–35 | Scan for the five red-flag terms: fragrance, MI/BIT, sodium hypochlorite, quats, PEG compounds |
| 35–50 | Check certifications. EPA Safer Choice and EWG Verified are meaningful. “Natural” is not. |
| 50–60 | Cross-reference one unfamiliar ingredient on EWG’s database |
Your Practical Next Action
Before you reach for your regular cleaning spray today, flip it over. Give it the 60-second scan above. You’re not looking to throw everything out — you’re looking to understand what you’re choosing. Write down any ingredient that flags your concern, look it up on EWG, and decide from there.
If you’re starting fresh and want a product that was built to survive this exact audit — one where Elizabeth personally documented the reason for every ingredient before we put it in production — the unscented version of our kit is the cleanest starting point we offer. No fragrance entry to hide behind. Every ingredient named. But the more important thing, right now, is that you do this exercise with whatever’s already under your sink. Knowledge first. Product decisions follow.

Frequently asked
Do cleaning products legally have to list all their ingredients?
No. Unlike food, cleaning products in the US have no federal law requiring full ingredient disclosure. The EPA Safer Choice program and California's Cleaning Product Right to Know Act are the strongest disclosure standards currently in effect, but neither applies to every product on the shelf.
What does 'fragrance' mean on a cleaning product label?
It's a legal catch-all term. Under FDA trade-secret rules, a single 'fragrance' listing can represent a blend of dozens or even hundreds of undisclosed chemicals, some of which are allergens, hormone disruptors, or VOCs.
Is 'plant-based' on a label a regulated claim?
No. 'Plant-based,' 'natural,' and 'green' are unregulated marketing terms. They have no legal definition in cleaning products. Always look past the front label to the ingredient list.
How do I look up an ingredient I don't recognize?
Search the INCI name directly in EWG's Skin Deep database (ewg.org/skindeep) or EWG's Guide to Healthy Cleaning. You'll get a hazard score from 1–10 and the specific concerns associated with that ingredient.
What is a Prop 65 warning on a cleaning product?
It means California has determined the product contains at least one chemical known to cause cancer, birth defects, or other reproductive harm. The list has over 900 chemicals. Seeing this warning is a signal to dig deeper into the ingredient list.
