How to Tell If a Laundry Detergent Is Really Plant-Based

In the United States, "plant-based" is not a defined term for cleaning products. No federal agency sets a minimum plant content for the phrase, and no agency reviews it before it goes on a box. A laundry detergent can print "plant-based" on the front of the pack without meeting any defined threshold, because no threshold exists. It can still be sued over — the FTC can act under Section 5 of the FTC Act if the overall impression misleads — but nothing stops the words going on the box in the first place.

That does not make every claim false. It means the claim carries no information on its own, and the information you actually want sits somewhere else: on the back of the pack, on the manufacturer's ingredient disclosure page, or in a reply to an email. Below is a five-step check you can run on any detergent in about ten minutes — including Love Paks, which we run it on at the end.

1. Look for named ingredients, not category words.
2. Check whether the whole formula is disclosed, with CAS numbers.
3. Separate the formula from the film, the pouch and the fragrance.
4. Read any certification for what it actually verifies.
5. Email the brand three questions and judge the answer.

The label words that are not regulated in the United States

Two federal bodies set the baseline for what a laundry detergent label must and may say — and, as Step 2 shows, two states go further. Neither federal body defines "plant-based."

The Consumer Product Safety Commission enforces the Federal Hazardous Substances Act, which requires precautionary labeling on hazardous household products: a signal word, the hazard, the common or chemical name of the substance responsible for the hazard, precautions, first aid, a keep-out-of-reach-of-children warning, and the manufacturer's name and address. It does not require a full ingredient list. A detergent can be fully FHSA-compliant and tell you almost nothing about what is in it.

The Federal Trade Commission publishes the Green Guides at 16 CFR Part 260. These are administrative interpretations, not rules — in the FTC's own words, they "do not confer any rights on any person and do not operate to bind the FTC or the public." The FTC can still sue under Section 5 of the FTC Act if a claim is deceptive; the Guides describe what it would likely consider deceptive.

A third federal agency governs one narrow slice of the label. If a laundry product claims to sanitize, disinfect or kill bacteria, that claim makes it a pesticide under the Federal Insecticide, Fungicide, and Rodenticide Act, and it must be registered with the Environmental Protection Agency before the claim can be made. FIFRA says nothing about "plant-based." It is worth knowing only so you can tell a registered antimicrobial claim apart from an unreviewed marketing word sitting next to it on the same box.

Part 260 has seventeen sections. They cover general environmental benefit claims, carbon offsets, certifications and seals of approval, compostable, degradable, free-of, non-toxic, ozone-safe, recyclable, recycled content, refillable, renewable energy, renewable materials and source reduction. There is no section on "plant-based," "natural" or "organic." The closest is § 260.16, renewable materials, which tells marketers to qualify a "made with renewable materials" claim "unless the product or package (excluding minor, incidental components) is made entirely with renewable materials."

Which leaves the words on the front of a detergent pack sorting into three tiers: undefined, guided but not pre-approved, and issued by somebody who checked something. The table below groups them that way.

Step 1: look for named ingredients, not category claims

Turn the pack over. Category words live on the front; names live on the back or on a website. If no ingredient is named anywhere, you have finished Step 1 and the answer is no — not "this brand is lying," but "this brand has published nothing you can check."

When you do find names, understand what "plant-derived" means at the chemistry level: it describes where the carbon came from, not what the molecule is. A surfactant built from coconut or corn feedstock is still a synthesized surfactant, not a plant. This is not an accusation — it is how detergents work, and a plant feedstock is a legitimate design choice. It just means "plant-derived" and "unprocessed" are different words.

The US government makes the distinction precise. USDA's BioPreferred Program measures biobased content with ASTM D6866, a radiocarbon method that expresses biobased content as the ratio of new organic carbon to total organic carbon. It measures the age of the carbon. That is all a plant-origin percentage ever means.

Where to look an ingredient name up

There is no official government list of "laundry detergent ingredients to avoid," and any list that presents itself that way is somebody's editorial judgment. There are, however, three free public sources that let you check a specific name yourself:

• EPA's Safer Chemical Ingredients List. Search by chemical name or CAS number. Each entry carries a symbol: a green circle means the chemical "has been verified to be of low concern based on experimental and modeled data"; a green half-circle means it is expected to be of low concern and more data would help; a yellow triangle means it meets Safer Choice criteria for its functional class "but has some hazard profile issues"; a grey square means it may not be acceptable in a Safer Choice product at all.
• California's designated lists. The Cleaning Product Right to Know Act points to 22 hazard lists — Proposition 65 carcinogens and reproductive toxicants, IARC Group 1, 2A and 2B carcinogens, EU Category 1A and 1B carcinogens, persistent bioaccumulative toxics and others. If an ingredient appears on one of them, California requires it on the label of products sold there.
• A brand's own disclosure page (Step 2), where each ingredient should carry a CAS number and a stated functional purpose.

One specific name is worth knowing because it goes straight to the greenwashing question. 1,4-dioxane is not an ingredient anyone adds. It can form as a byproduct during the manufacture of certain ingredients — the ethoxylated surfactants and foaming agents common across cleaning products — which is why it appears in disclosure rules as a contaminant rather than as a line in a formula. California sets a disclosure threshold for it at 10 ppm, described in Step 2. New York restricts how much of it household cleansing products sold in that state may contain; the operative limit sits in New York's Environmental Conservation Law Article 35, and that statute, rather than anyone's marketing page, is where to read the current number. The point for this checklist is narrower: a plant-derived feedstock does not rule 1,4-dioxane out, because it arises from a manufacturing step rather than from the source of the carbon. This is exactly why "plant-based" and "safe" are separate questions.

Step 2: check whether the whole formula is disclosed

Two state laws did what no federal law does, and they are the reason most national brands now publish an ingredient page.

California — Cleaning Product Right to Know Act of 2017 (SB 258). For "designated products," which includes general cleaning products, the manufacturer's website must carry, in an electronically readable format: every intentionally added ingredient (fragrance ingredients and genuine confidential business information excepted), the functional purpose of each, nonfunctional constituents present at 0.01 percent (100 ppm) or more, 1,4-dioxane at 0.001 percent (10 ppm) or more, a CAS number for each listed ingredient, links to any designated list an ingredient appears on, and a link to the Safety Data Sheet. Online disclosure became mandatory on January 1, 2020; label disclosure on January 1, 2021. The label itself must carry either the designated-list chemicals plus fragrance allergens, or all intentionally added ingredients — plus a toll-free number and the web address.

New York — Household Cleansing Product Information Disclosure Program (Environmental Conservation Law Article 35 and 6 NYCRR Part 659). It requires disclosure by weight, the functional role of each intentionally added ingredient, and flags for ingredients on lists of chemicals of concern.

What to actually do

Search for the brand name plus "ingredient disclosure" or "ingredients." Then grade what you find:

• Strong. Every ingredient named, each with a CAS number and a functional purpose, plus a Safety Data Sheet link.
• Partial. Ingredients named but no CAS numbers, or a list that stops at "and other cleaning agents."
• Weak. "Proprietary plant-based blend," and nothing else.
• Absent. No page at all. That is a real finding, and it is the most common one.

Two caveats keep this fair. Fragrance is carved out of California's ingredient-by-ingredient rule, so a compliant page can still say "fragrance" as one line. And confidential business information is a lawful exception, not automatically a dodge — though a brand claiming it for its entire formula has told you something.

Step 3: separate the formula from the film, the pouch and the fragrance

Laundry paks as a category are three separate materials: the detergent inside, the water-soluble film wrapped around it, and the pouch or box it ships in. A claim can be perfectly true of one and false of the others, and most confusion in this category comes from a claim sliding between them. Film is the piece brands most often leave unspecified — Love Brands, for its part, says it does not currently publish a film specification for Love Paks, which is the subject of its article on laundry paks without PVA plastic film.

The FTC's own worked example in § 260.8 is a shampoo advertised as biodegradable where the ad makes clear that only the shampoo, not the bottle, is meant. The standard for an unqualified degradable claim is competent and reliable scientific evidence that the item "will completely break down and return to nature (i.e., decompose into elements found in nature) within a reasonably short period of time after customary disposal" — and for anything entering the solid waste stream, an unqualified claim is deceptive if the item does not completely decompose within one year.

So when you see a degradation word, ask three things: what degrades, under which test standard, and in which disposal environment.

A good answer names a standard. The common one for cleaning-product ingredients is OECD Test Guideline 301, Ready Biodegradability, adopted in 1992, which sets out six methods (301 A through F). Its pass levels are stated plainly: "70% removal of DOC and 60% of ThOD or ThCO2 production for respirometric methods," reached inside a 10-day window that begins at 10% biodegradation and must end before day 28. Chemicals that reach the pass levels after 28 days "are not deemed to be readily biodegradable." A brand that can point to an OECD 301 result for its surfactants has said something checkable. "Biodegradable" alone has not. Our companion piece on biodegradable versus microplastic laundry paks goes deeper on the film question.

Fragrance is its own category

"Fragrance" on a label is one word standing in for a mixture. California requires fragrance allergens from Annex III of the EU Cosmetics Regulation to be disclosed when present at 0.01 percent (100 ppm) or more — which is the disclosure most people are looking for when they say they react to a detergent. Note also that "dye-free" and "fragrance-free" are two different statements: see fragrance-free versus scented laundry detergent. If skin is the reason you are reading this at all, start instead with what to consider when choosing a detergent for sensitive skin.

Step 4: what third-party certifications actually verify

A seal is worth exactly what the issuing body checked. The FTC's position is that a marketer "should not use environmental certifications or seals that do not convey the basis for the certification," and that third-party certification "does not eliminate a marketer's obligation to ensure that it has substantiation for all claims reasonably communicated by the certification."

Here is what the two US government programs relevant to laundry detergent actually verify, alongside two things people mistake for certifications.

The practical test: a real certification has a public listing you can search. Safer Choice products appear in EPA's product list; USDA Certified Biobased products appear in the BioPreferred catalog with their percentage. If a brand names a certification but cannot give you a listing number, the certification is the claim, not the evidence.

Step 5: three questions worth emailing a brand

Everything above can be done from your sofa. This last step is the one that separates brands that have the data from brands that have the adjective. Send these three, verbatim.

1. "Which ingredients in this product are plant-derived, and what percentage of the formula do they represent? Please state the basis — by weight, by weight excluding water, or as biobased carbon under ASTM D6866." The basis matters more than the number. One formula can produce three very different percentages depending on what is being counted, so a percentage with no stated basis cannot be compared with anyone else's percentage.
2. "Where can I find the full ingredient list, with a CAS number and the functional purpose of each ingredient?" If the brand sells in California or New York, a page like this is a legal expectation, not a favor.
3. "For each environmental word on the pack — biodegradable, free-of, or similar — what exactly does it apply to, under which test standard, and in which disposal environment?"

A good answer is specific and slightly boring: a list, a standard number, a percentage with its basis. A non-answer restates the marketing. You do not need a chemistry degree to tell the two apart.

Running the checklist on Love Paks

It would be a strange article that taught this test and then exempted the brand publishing it. So, honestly:

What Love Brands publishes today

• Format and dose. Love Paks are pre-measured laundry detergent paks. There are 39 paks in a refill pouch. One pak handles a standard load; use two for a large or heavily soiled load. Nothing here is a claim — it is countable, which is why it leads.
• Two products. Citrus Flower Blossom is the scented version. Dye & Scent Free has no dyes and no added fragrance.
• Machines and water. Warm or cold water; standard and high-efficiency machines.
• The formula. Love Brands describes the Love Paks formula as plant-based.
• The name. LOVE PAKS is a registered US trademark, Reg. No. 8371488. As Step 4 says: that is a naming right and nothing more.

What is not published yet

By this checklist's own Steps 1 through 4, four things are missing, and it is more useful to say so than to pretend otherwise:

• A full ingredient list with CAS numbers and functional purposes.
• A plant-derived share with a stated basis — the answer to Question 1 above.
• A film specification, which Love Brands says it does not currently publish for Love Paks.
• Any third-party certification listing number. Love Brands does not currently publish one, so Love Paks should not be read as carrying EPA Safer Choice, USDA Certified Biobased, or any other independent mark.

One clarification about what that list is and is not. It describes what Love Brands has published as of today, so that you can run Steps 1 through 4 on this brand exactly as you would run them on any other. It is not a legal conclusion about any company, Love Brands included. Whether a particular state disclosure program reaches a particular product, and what it requires of a particular seller, turns on facts this page does not assess — the statutes themselves are the place to read that, and the company is the place to ask.

Which makes the fair conclusion this: "plant-based" on Love Paks is Love Brands' own description, and you are entitled to treat it exactly the way this page tells you to treat any brand's — as a claim awaiting a named list and a number. If you want that answer, ask Love Brands about the formula. It is a reasonable question and it is the same one we have asked you to send to everyone else.

Rose quartz: four different kinds of statement

Love Paks are described as rose quartz infused, and that raises a labeling question this page is built to handle. Keep four registers apart, because they are not interchangeable.

A related trap, and a general lesson for Step 1: a product name is a name, not a described mechanism. "Aura Frequency Starter Pack" is the name of a separate Love Brands product; "frequency" there is part of a product line's name, not a property of the rose quartz and not a claim about how anything works. The same reading applies to every "Pure," "Botanical" or "Ultra" on any shelf. Background reading: what rose quartz is in Love Paks.

The short version

1. Ignore the front of the pack. "Plant-based" and "natural" are undefined for cleaning products in the US.
2. Find named ingredients. Look each one up in EPA's Safer Chemical Ingredients List.
3. Find the disclosure page. Grade it on CAS numbers and functional purposes.
4. Ask what any degradation claim applies to, and under which standard.
5. Ask for a percentage with its basis, and for a certification listing number.

Run it on Love Paks yourself — start with Citrus Flower Blossom and Dye & Scent Free, or the overview at how Love Paks work. If a question is not answered there, the Love Brands FAQs are the next stop.

Frequently asked questions

Is "plant-based" a regulated term for cleaning products in the United States?

No. No federal statute or regulation defines "plant-based" for cleaning products, and the FTC's Green Guides at 16 CFR Part 260 — which cover general environmental benefit, certifications, compostable, degradable, free-of, non-toxic, recyclable, recycled content, refillable, renewable energy, renewable materials and source reduction claims — contain no section on "plant-based," "natural" or "organic." The closest guidance is § 260.16 on renewable materials, which tells marketers to qualify the claim unless the product is made entirely with renewable materials.

What percentage of a detergent has to be plant-based to use the phrase?

There is no legal minimum. A product can say "plant-based" with any share of plant-derived content. The only US program that attaches a number to plant origin is USDA's BioPreferred Program: to carry the USDA Certified Biobased Product label, a product must meet the minimum biobased content set for its designated category, or 30 percent if USDA has not designated its category (7 CFR 4270.4). That label always prints the certified percentage, and the percentage is measured by ASTM D6866 radiocarbon testing at an independent lab.

Is plant-based laundry detergent just greenwashing?

Not inherently — but the phrase itself does no work, so the honest answer depends entirely on the brand. The test is whether a company can produce a named ingredient list, a plant-derived percentage with a stated basis, and any certification listing number. Brands that can are not greenwashing. Brands that answer with more adjectives have given you your answer. Note that a plant feedstock says nothing about safety on its own: 1,4-dioxane, for instance, forms as a manufacturing byproduct of detergents and foaming agents regardless of whether the carbon came from a plant.

Which laundry detergent ingredients should I avoid?

There is no official government list of ingredients to avoid in laundry detergent, and lists presented that way are editorial judgment rather than regulation. Instead, look up each named ingredient in EPA's Safer Chemical Ingredients List, where entries carry a green circle, green half-circle, yellow triangle or grey square rating; and check whether it appears on one of the 22 hazard lists California's Cleaning Product Right to Know Act designates, which include Proposition 65 and IARC Groups 1, 2A and 2B. If you react to detergents specifically, fragrance allergens are the disclosure to look for — California requires those from Annex III of the EU Cosmetics Regulation to be listed at 0.01 percent (100 ppm) and above.

Does "plant-derived" mean the ingredient is unprocessed?

No. "Plant-derived" describes the origin of the carbon, not the state of the molecule. Most detergent surfactants built on plant feedstocks are synthesized compounds. That is why ASTM D6866 — the method USDA uses — measures biobased content as the ratio of new organic carbon to total organic carbon: it is a test of where the carbon came from, and nothing else.

Does a registered trademark prove anything about a formula?

No. A US trademark registration establishes rights in a name as a source identifier for particular goods, and that is the whole of it. LOVE PAKS, for example, is registered on the USPTO Principal Register as Reg. No. 8371488, registered July 28, 2026, and that registration expressly disclaims exclusive rights to the word "PACKS" — a naming right, not a statement about ingredients and not a certification. Any ® on a detergent box should be read the same way.

Are "dye-free" and "fragrance-free" regulated claims?

They are "free-of" claims, which the Green Guides address at § 260.9. A truthful free-of claim can still be deceptive if the product uses a substance that poses the same or similar environmental risk as the one removed, or if that substance was never associated with the product category to begin with. So the useful follow-up is not "is it free of X" but "what is in it instead." "Dye-free" and "fragrance-free" are also two separate statements and are frequently confused for each other.

How do I check whether a brand really discloses its ingredients?

Search the brand name plus "ingredient disclosure." Under California's Cleaning Product Right to Know Act, a compliant page lists every intentionally added ingredient with a CAS number and a functional purpose, nonfunctional constituents at 100 ppm and above, 1,4-dioxane at 10 ppm and above, links to any designated hazard list, and a link to the Safety Data Sheet. New York runs a separate disclosure program under Environmental Conservation Law Article 35 and 6 NYCRR Part 659. Fragrance ingredients and genuine confidential business information are lawful exceptions — but a blanket confidentiality claim over an entire formula is itself informative.

New York runs a separate disclosure program under Environmental Conservation Law Article 35 and 6 NYCRR Part 659.
