Walk down any cleaning aisle in 2026 and you'll find the same vocabulary on almost every bottle: plant-based, natural, non-toxic, eco-friendly, green, clean, plant-derived, planet-safe, biodegradable. Each one designed to make you feel better about reaching for it.
Here's the problem: most of those words have no legal definition. A manufacturer can put "plant-based" on a bottle that's 1% citrus oil and 99% petroleum surfactants and never break a single rule. The FTC has tried to crack down on the worst offenders, but enforcement is slow and the marketing keeps moving faster than the regulators.
We use three ingredients in Carbon Cleanse, and one of them is d-Limonene from citrus peels. So when we say "plant-based," we mean something specific. The point of this post isn't to brag about our label, it's to give you the tools to read any label and figure out what's real and what's marketing copy.
Let's go through the words one by one.
The Short Answer
Most environmental claims on cleaning products are unregulated marketing language. A handful of terms, "biodegradable, recyclable, compostable, non-toxic? do have FTC guidelines that companies are supposed to follow, but enforcement is rare and qualifications are often buried in fine print. The two phrases consumers trust most, plant-based and natural, have no legal definition at all.
The only reliable signals are third-party certifications backed by ingredient-level review: EPA Safer Choice, EPA Design for the Environment (DfE), Green Seal, EWG VERIFIED, and Cradle to Cradle Certified. Anything else is a brand telling you to trust them.
That doesn't mean every uncertified brand is lying. It does mean you need a different way to evaluate them: full ingredient disclosure, no proprietary blends, and ingredient names you can actually look up.
The FTC Green Guides — What They Cover, What They Don't
The Federal Trade Commission publishes the Green Guides (16 CFR Part 260), which lay out what companies can and can't claim about the environmental attributes of their products. They were last updated in 2012 and the FTC has been working on a revision for years.
The Green Guides are not law in the traditional sense. They're guidance, but the FTC uses them to bring enforcement actions under Section 5 of the FTC Act when claims are deceptive. Companies have been fined and forced to change packaging because of them.
Here's what the Green Guides actually say about the language you see on cleaning bottles:
"Non-toxic" — Must be qualified. The FTC has stated that calling a product "essentially" or "practically" non-toxic is deceptive without context. A non-toxic claim must specify non-toxic to whom, humans, pets, aquatic life, the environment broadly, and must be substantiated with evidence.
"Biodegradable" — Must be supported by evidence that the product or material will completely decompose within a reasonably short time after customary disposal. Unqualified biodegradable claims have been challenged when the product ends up in a landfill where degradation doesn't occur.
"Recyclable" — Requires that recycling facilities are available to a substantial majority of consumers where the product is sold. If only a small fraction of consumers have access to facilities that accept the material, the claim must be qualified.
"Refillable" — Requires that the company provides a means to refill the package (refill stations, refill products sold separately, etc.).
"Compostable" — Requires evidence that the product will break down into usable compost in a safe and timely manner in an appropriate composting facility or home compost pile.
Notice what's not on this list: plant-based, natural, eco-friendly, green, planet-safe, clean. None of those terms are addressed in the Green Guides because there's no agreed scientific or regulatory definition for any of them.
The Big Five Unregulated Terms
These are the phrases that show up most often on cleaning bottles. None of them mean what most consumers think they mean.
"Plant-Based"
There is no legal definition of plant-based in the United States. A product can be labeled plant-based if it contains any meaningful percentage of plant-derived ingredients — and "meaningful" is whatever the manufacturer says it is. Some brands use it when their primary active ingredient comes from plants. Others use it when a single fragrance compound is plant-derived and the rest of the formula is petroleum-based.
What to look for instead: Does the brand disclose every ingredient? Can you trace each one back to a plant source by name (citrus peel, coconut, corn, sugar beet, palm)? If the ingredient list says "plant-derived surfactant" without naming the specific surfactant, that's marketing copy, not transparency.
"Natural"
This is the most abused word in the entire category. The FDA has explicitly stated that it has not defined "natural" for food products, and there is no equivalent regulation for cleaning products at all.
"Natural" can mean almost anything: derived from a natural source, processed using natural methods, contains some natural ingredients, smells natural. Synthetic chemicals derived from natural feedstocks can be labeled natural. Petroleum is technically natural, it comes from the ground.
What to look for instead: Ignore the word. Look at the actual ingredient list.
"Non-Toxic"
The FTC requires this claim to be qualified (non-toxic to what?), but enforcement is inconsistent and most brands hedge with phrases like "non-toxic formula" or "non-toxic ingredients." There's no concentration threshold, no required testing standard, and no required disclosure of what tests were performed.
A product can be marketed as non-toxic if its acute oral toxicity in rats is above a certain threshold. That doesn't mean it's non-toxic when you breathe it in over years, get it on your skin, or pour it down the drain into a watershed.
What to look for instead: Third-party certifications that test for chronic toxicity, endocrine disruption, aquatic toxicity, and respiratory sensitization — not just "won't kill you if you drink it."
"Eco-Friendly" / "Green" / "Planet-Safe"
These are pure marketing terms. The FTC explicitly calls out "eco-friendly" and "green" as examples of unqualified general environmental benefit claims that are likely to be deceptive without specific substantiation. There is no test, no standard, and no regulator who decides what qualifies.
What to look for instead: Specific, verifiable claims. "Biodegrades within 28 days under OECD 301 testing" is a real claim. "Eco-friendly" is not.
"Clean" / "Clean Ingredients"
A relatively new entrant to the marketing vocabulary, "clean" was popularized by the beauty industry (clean beauty) and migrated to household products. It has no definition whatsoever. Sephora, Credo Beauty, and other retailers have their own internal "clean" standards, but they don't agree with each other and none of them are regulated.
What to look for instead: Full ingredient disclosure, no "fragrance" or "parfum" blanket terms hiding undisclosed compounds, and verifiable hazard data on every ingredient.
The Certifications That Actually Mean Something
Not all eco-labels are equal. Some are rigorous third-party evaluations. Others are pay-to-play badges that mean almost nothing. Here are the ones worth trusting:
EPA Safer Choice (and DfE)
This is the gold standard in North America. To carry the Safer Choice label, every ingredient in a product, down to 0.01% concentration, must be reviewed by EPA-credentialed third-party toxicologists. Products must meet criteria across thirteen human and environmental health endpoints. Carcinogens, reproductive toxicants, developmental toxicants, persistent bioaccumulative toxics, and known endocrine disruptors are excluded categorically, even if those ingredients are technically "plant-derived." Surfactants must be readily biodegradable under OECD 301 testing protocols.
The certification requires a three-year partnership with the EPA, an on-site manufacturing facility audit, and a toxicological renewal review at the end of each cycle.
The Design for the Environment (DfE) label is the equivalent program for antimicrobial products (disinfectants, sanitizers) and applies the same Safer Choice Standard plus pesticide registration requirements.
Green Seal
An independent nonprofit certifier with 35 years of eco-labeling history. Green Seal evaluates the full lifecycle of a product, raw materials, manufacturing, use, and disposal, against published standards. More than 100 federal, state, and local government purchasing policies specifically require Green Seal certification, which gives it real institutional weight.
EWG VERIFIED
The Environmental Working Group's strictest certification tier. Products must fully disclose all ingredients (including fragrance components), avoid EWG's list of chemicals of concern, and meet manufacturing transparency requirements. EWG also maintains the publicly searchable Skin Deep and Guide to Healthy Cleaning databases, which let you look up individual ingredients and product scores.
Cradle to Cradle Certified
A multi-attribute certification covering material health, product circularity, clean air and climate protection, water and soil stewardship, and social fairness. More expansive than Safer Choice but also more focused on lifecycle and supply chain rather than ingredient-by-ingredient toxicology.
ECOLOGO (UL)
A North American standard administered by UL Solutions, recognized by the EPA's Environmentally Preferable Purchasing program. Lifecycle-based criteria covering toxicity, biodegradability, and packaging.
The Badges That Mean Less Than You Think
Self-created seals. "Green Safety Shield," "Eco-Approved," "Earth-Tested" — if you've never heard of the certifying body, search for it. Many "certifications" on cleaning products are awards companies created and granted to themselves. The FTC has brought cases against brands that did exactly this.
Recycling symbols on non-recyclable packaging. The chasing-arrows triangle around a plastic resin code (1–7) is not a recycling claim. It identifies the resin type. Whether the package is actually recyclable depends on your local recycling program. The FTC requires unqualified recyclable claims to be substantiated by recycling access for a substantial majority of consumers.
Color and imagery as implied claims. Green packaging, leaf logos, watercolor illustrations of forests — none of these have any regulatory meaning. They are designed to imply environmental virtue without making a specific claim that could be challenged.
Vague endorsements. "Trusted by experts." "Dermatologist tested." "As recommended by." If the brand doesn't say which experts, which dermatologists, or who recommended it, the phrase is decorative.
How to Actually Read a Cleaning Product Label
When the marketing language is stripped away, here's what to look for:
1. Is every ingredient disclosed by name? Not "natural surfactant" — the specific surfactant. Not "essential oil blend" — the specific oils. If the label says "and other ingredients" or hides anything under "fragrance," the brand is choosing not to tell you.
2. Can you look up each ingredient? Type the chemical name into the EWG Skin Deep database or the EPA's Safer Chemical Ingredients List. If you can find it, you can evaluate it. If the brand uses proprietary trade names that don't appear in any database, you can't.
3. How many ingredients are there? A typical conventional cleaning product has 15–30 ingredients. Some of that complexity is necessary (preservatives, stabilizers, pH buffers). Some of it is not. Shorter ingredient lists aren't automatically safer, but they're easier to verify.
4. What's the active concentration? A 1% d-Limonene formula is doing very different cleaning than a 30% d-Limonene formula. If the brand doesn't tell you the concentration of the working ingredients, you can't compare products meaningfully.
5. Does the brand make specific, falsifiable claims? "Biodegrades within 28 days" can be verified. "Eco-friendly" cannot. The more specific the claim, the more confidence you can have in it.
6. Is there a third-party certification you recognize? EPA Safer Choice, Green Seal, EWG VERIFIED, Cradle to Cradle. If you don't recognize the certifier, look it up.
The Full Picture: What's Real, What's Not
✓ TRUE: Most environmental claims on cleaning products are unregulated marketing language with no legal definition.
✓ TRUE: The FTC Green Guides regulate specific terms — biodegradable, recyclable, compostable, refillable, non-toxic — but enforcement is inconsistent and the guides haven't been updated since 2012.
✓ TRUE: Third-party certifications like EPA Safer Choice, Green Seal, and EWG VERIFIED require ingredient-level review and are meaningful signals of safety and transparency.
✓ TRUE: Full ingredient disclosure, by specific chemical name and at known concentrations, is the single most reliable indicator of a transparent brand.
✗ FALSE: "Plant-based," "natural," "eco-friendly," and "green" have regulatory definitions. They do not.
✗ FALSE: A green leaf logo or earth-toned packaging means a product is environmentally safer. Packaging design is unregulated.
✗ FALSE: All certifications are equivalent. Self-created seals and pay-to-play badges are common.
How Carbon Cleanse Reads Its Own Label
We use three ingredients: purified water, d-Limonene at 5% concentration, and decyl glucoside at 5% concentration. We've published companion posts explaining each one and where it comes from:
- What Is d-Limonene? The Natural Citrus Solvent Behind Carbon Cleanse
- Is d-Limonene Safe?
- What Is Decyl Glucoside? The Plant-Based Surfactant Behind Carbon Cleanse
Every ingredient is disclosed by name. Every concentration is published. Every claim we make about safety links to the underlying FDA, EPA, or peer-reviewed source. No "natural" without specifics. No "fragrance" hiding undisclosed compounds. No proprietary blends.
That's what we mean by plant-based. It's not a marketing claim. It's a verifiable description of what's in the bottle.
Three Ingredients. Full Transparency.
No hidden formulas. No fine print. Just the cleanest clean you've ever had.
