If you have stood in front of a supplier catalogue lately, you have seen the pattern. Half a dozen products, all promising the same thing: Plant-based. Biobased. Naturally derived. Powered by nature.
Each one sounds like the others, and nothing on the pages tells you which claim is doing real work and which is just jargon. Then you try two of them and they do not perform the same way. One cuts grease in the back of house kitchen and the other needs a second pass. Both were “plant-based.”
The gap is not a mystery, and it is not bad luck. It happens because most green claims describe different attributes entirely – some describe where an ingredient came from , some describe how it was made, some describe what an independent body has verified. Those are three separate attributes and a label often answers only one of them.
Here’s how to tell them apart.
“Biobased” tells you where the ingredient came from
Biobased means the raw material is renewable rather than fossil-derived – corn, sugar, plant oils, forestry or marine material instead of petroleum. That is the whole claim. It is a sourcing statement.
It is a meaningful one. Replacing petroleum feedstock with renewable feedstock genuinely changes a product’s footprint, and it is a legitimate attribute for a supplier to be proud of. Notice what it doesn’t tell you: it says nothing about how the ingredient was processed, what molecule came out the other end, or how well the finished product cleans. Two cleaners can both be biobased and perform nothing alike, because biobased describes the starting material, not the final chemistry in the product.
Where it gets more useful is when it comes with a number. A USDA BioPreferred Certified Product label states a verified biobased content percentage. The share of a product’s organic carbon that comes from renewable sources rather than fossil ones, measured by a standardized lab test rather than asserted by the manufacturer. Minimum thresholds vary by product category, and the label can report the product and its packaging separately. A percentage on a label is a real, tested number. Treat it with respect and ask for it when it is missing.
A biosurfactant tells you how the ingredient was made
A surfactant is the part of any cleaner that does the actual lifting. It loosens soil from a surface and holds it in suspension so it can be rinsed or wiped away. Every cleaning product on your shelf has one. It is the engine.
A biosurfactant is a surfactant produced by microbes. Microbes are fed a feedstock and they manufacture the surfactant molecule themselves, in much the same way brewing or cheesemaking works. That is a different production route from conventional surfactants, which are synthesized using a linear, wasteful processes rather than a circular environmentally conscious route.
This is the distinction most buyers miss, so it is worth stating plainly: bio-based and biosurfactant are not synonyms, and one does not imply the other. A product can be made from renewable feedstock and still use conventional linear wasteful processes to synthesize surfactants. A biosurfactant is a claim about the manufacturing process and the resulting molecule, which is to say a claim about the part of the product that determines how it works rather than what it is made from.
So when two biobased products perform differently, the cleaning mechanism is usually where the answer lives. Ask what the active ingredient is and how it is produced. That single question determines products that share only a marketing category but not product performance and formulation.
What a certification mark actually certifies
Certification marks are the most trusted thing on a label and the most commonly misread. Each one answers a narrow specific question; does it meet the criteria for the certification. None of them is a general endorsement of a product being good for the environment or safe to use.
A quick orientation to the four you will see most often in Canadian institutional buying:
- USDA BioPreferred: a United States Department of Agriculture program that verifies biobased content as a percentage, lab-tested. It answers: how much of this came from renewable material? It does not assess performance or toxicity.
- Green Seal: an independent non-profit certifier operating to ISO 14024 Type 1 rules, with a long-standing standard for institutional and industrial cleaning products. It takes a lifecycle view: restricted ingredients, VOC limits, packaging requirements and performance criteria together.
- ECOLOGO (UL): a multi-attribute, lifecycle certification with separate standards written for separate product types, so hard-surface cleaners and carpet care are assessed against different criteria. It answers: does this product meet the environmental and performance bar set for its specific category?
- EPA Safer Choice: a United States Environmental Protection Agency program built primarily on ingredient by ingredient screening, with performance testing and a packaging review alongside it.
Two things follow from this, and both are practical.
First, a mark is only as relevant as the question it answers. A biobased percentage tells you nothing about aquatic toxicity. A lifecycle certification tells you nothing about renewable content specifically. If your sustainability mandate is written around one concern, check that the mark on the bottle actually addresses that concern.
Second, the absence of a mark is not the absence of evidence. Certification is voluntary, paid, per formulation process, and it takes time – a reformulated product has to be re-certified even when it performs better than the version that held the certificate originally. Newer chemistries routinely sit in that gap. An uncertified product may have test data, a documented mechanism and a verified biobased percentage behind it. The right response to a missing mark is to ask what evidence exists instead, not to assume there is none.
Four questions worth taking into your next supplier conversation
- What is the biobased percentage, and how was it verified? A supplier who knows the number will say it. A supplier who says “high” or “mostly” is estimating.
- What is the active surfactant, and how is it produced? Look out for biobased claims that use traditional chemistry such as ethoxylated alcohols which can be made from biobased sources, but always have 1,4-dioxane impurities (a known cancer causing chemical.)
- What exactly is this certified against, and does the certificate match this SKU? Certificates are issued per formulation and per code pack as well.
- What data sits behind the performance claim? Ask for the test, the soil type and the surface.
A supplier who answers all four plainly is a supplier worth shortlisting, one who deflects on all four has told you something too.
Where Project Clean sits
Our Natural line is built on biosurfactant technology developed through our partnership with Dispersa, a Canadian cleantech company that ferments food-processing waste into functional cleaning ingredients. The surfactant doing the work in those products is made by microorganisms from material that would otherwise have gone to landfill, and our formulation team at the Creation Lab in B.C. builds the finished product around it – balancing pH and foam, and testing across surfaces so performance holds from one job to the next. The formulas in the line are more than 90% biobased. Certification pending.
Cream Cleanser Natural sits in the line on its own footing: a plant-based formula that holds Green Seal Certification and USDA Certification at 99% biobased.
This is the same thing we are asking of everyone else in the category. Say which claim you are making, say what backs it, and let the buyer compare like with like.
