Bulk concentrate, for programs
Non-toxic and fermented cleaning brands now lead with lab numbers: a precise efficacy percentage, a safety multiple “safer than table salt”, a preservative-free pass. Those numbers beat vague “natural” marketing, but only if you can read the test behind them. ECS is not a competing cleaner brand, so we evaluate fermented, plant-based and conventional bio-actives on the same evidentiary bar and tell you which claims are substantiated and which are decorative.
- ASTM D4488 cleaning power
- OECD 425 acute oral safety
- USP 51 preservative effectiveness
- Independent lab report required
For hospitality, restaurant, daycare and facility buyers. We match a substantiated bio-active to the surfaces and soils you actually face.
Start here
A lab number is a comparator, not a guarantee.
A buyer who can read the test behind a claim can tell a genuinely substantiated cleaner from one borrowing the prestige of a standard it cited but did not really meet. A “95-point-something percent cleaning efficacy, ASTM D4488, tested by an independent lab, report linked” claim is strong. A bare “lab-proven 99 percent” with no method, no soil and no report is marketing.
A cleaning-efficacy percentage is meaningful only against its test conditions. Removing a standardized greasy soil from non-porous tile under lab conditions is not the same as cutting baked-on kitchen grease in a commercial kitchen, and no single number captures every use case. The buyer’s job is to confirm the test conditions resemble the real duty closely enough to matter, and to compare products tested the same way rather than across different methods.
What we evaluate and source
Three program applications, one evidence bar.
Each application leads with the test that proves the claim it depends on. We match the evidence to the duty you actually face.
Application
Hard-surface cleaning concentrate
For: hospitality, restaurant and facility hard-surface programs.
Efficacy is the gating claim, so the evidence is an ASTM D4488 result with the sub-method, soil and surface named, run by an independent accredited lab with the report linked.
- ASTM D4488 sub-method, soil type and surface stated
- Percent-efficacy number tied to those conditions
- Independent accredited lab, report linked
- Soils matched to your real duty
Application
Food-contact and produce wash
For: food-contact surfaces, produce washing, and any environment where ingestion risk matters.
Safety is the gating claim, so the evidence is an OECD 425 acute oral toxicity result and an explicit basis for any “safer than X” comparison, read as a bounded claim rather than a blanket safety certification.
- OECD 425 acute oral toxicity result
- Stated basis for any “safer than table salt” claim
- Note: acute oral is one dimension, not skin or inhalation
Application
Preservative-free facility concentrate
For: high-volume facility programs that want ingredient simplicity plus shelf stability.
Stability is the gating claim, so the evidence is a USP 51 pass without added preservatives, plus third-party BPA, PFAS and phthalate-free packaging verification kept in its own lane.
- USP 51 antimicrobial-effectiveness pass
- “Preservative-free” substantiated, not just label-omitted
- Packaging cert addresses the container, not the chemistry
The test stack
What each test proves, and what it does not.
Cleaner brands that lead with efficacy usually pair it with safety and stability data. Buyers should know exactly what each standard does and does not establish.
| Test | What it measures | What it proves | What it does not prove |
|---|---|---|---|
| ASTM D4488 | Hard-surface cleaning performance against a defined soil and surface under controlled conditions. | A comparable percent-efficacy figure when the sub-method, soil and surface are named. | Real-world performance on every soil; a single number is a comparator, not a guarantee. |
| OECD 425 | Acute oral toxicity, producing an LD50-type figure. | A specific, bounded acute-oral safety comparison (for example, vs sodium chloride). | Skin sensitization, inhalation or long-term exposure safety. |
| USP 51 | Antimicrobial (preservative) effectiveness of the formulation. | A “preservative-free” claim is real when the product passes without added preservatives. | Cleaning efficacy or toxicity; it is a stability claim only. |
| Packaging cert (BPA / PFAS / phthalate-free) | Container materials and migration. | The packaging is free of the named substances. | Anything about the cleaning chemistry itself; keep it in its lane. |
| Independence and auditability | Who ran the test and whether the report is linked and current. | The claim is verifiable rather than asserted. | Nothing on its own; it is the check on every claim above. |
Named methods, not marketing
The standards behind a credible claim.
A fermentation-based cleaner and a plant-based cleaner should both meet the same evidentiary bar: a named method, an independent lab, and a linked report. The category label is positioning; the test stack is evidence.
ASTM D4488
Cleaning power
An ASTM guide for cleaning-performance evaluation of hard-surface cleaners. Provides standardized methods so two products tested the same way can be compared.
OECD 425
Acute oral toxicity
A standardized method for estimating acute oral toxicity (an LD50-type figure). The basis for any legitimate “safer than table salt” comparison, for one dimension of safety.
USP 51
Preservative effectiveness
The antimicrobial-effectiveness test. A pass without added preservatives is the right evidence for a genuine “preservative-free” claim.
BPA / PFAS / phthalate-free
Packaging verification
Third-party verification of the container and migration. Worth having, but answers a different question than efficacy or toxicity.
Accredited lab
Independence
An independent accredited lab strengthens any result over a manufacturer’s own bench. Independence is what turns a number into evidence.
Linked report
Auditability
A current, identifiable, linked report makes a claim auditable rather than asserted. No report, no claim we will stand behind.
Some brands reject the “plant-based” category and position on fermentation instead, citing research that certain green cleaners can emit higher levels of chemical precursors associated with indoor-air-quality concerns. For a buyer the takeaway is not to pick a tribe but to evaluate the actual data: what was tested, by what method, by whom, and with what report.
Sourcing for a program
Have us read a cleaner’s evidence for your program.
Tell us the surfaces and soils you face, your volume and your safety constraints. We assess the candidate bio-actives’ test stacks on the same bar and tell you which claims are substantiated and which are decorative.
Why evaluate through ECS
Not a competing cleaner. The independent reviewer.
Because ECS does not sell its own cleaner brand, we can assess every candidate on the same evidence and tell you the truth about the gaps.
Same bar for every category
Fermented, plant-based and conventional bio-actives are scored on named methods, independent labs and linked reports, so the category label never substitutes for evidence.
Claims read in context
We tie every percent-efficacy number to its sub-method, soil and surface, and every safety multiple to its OECD 425 basis, so a bounded claim is never inflated into a blanket one.
Built for B2B programs
We serve the hospitality, restaurant, daycare and facility duty that consumer-direct brands ignore, matching a substantiated bio-active to your surfaces and soils.
Auditability enforced
If a product cites a standard in its copy but cannot produce a current, identifiable, linked report, we flag it before it enters your program.
Buyer questions
Cleaner evidence FAQ.
What does ASTM D4488 measure?
It is an ASTM guide providing standardized methods for evaluating how well a hard-surface cleaner removes a defined soil from a defined surface under controlled conditions. Its value is comparability: products tested under the same method, soil and surface can be compared on a percent-efficacy basis.
Is a “99 percent cleaning efficacy” claim trustworthy?
Only with context. Ask for the test method (the ASTM D4488 sub-method), the soil and surface used, whether an independent accredited lab ran it, and a linked report. A percentage without those details is a marketing number, not a substantiated one.
What does “safer than table salt” actually mean?
It compares the cleaner’s acute oral toxicity, measured by OECD Test Guideline 425, to the known acute oral toxicity of sodium chloride. It is a specific, legitimate comparison for one dimension of safety (acute oral), but it does not by itself address skin sensitization, inhalation or long-term exposure.
Does a USP 51 pass mean a cleaner is preservative-free?
USP 51 is the antimicrobial-effectiveness (preservative) test. Passing it without added preservatives substantiates a preservative-free claim by showing the formula resists microbial growth on its own. It is the right evidence for that specific claim.
Are fermented cleaners better than plant-based ones?
That is a positioning question, not an evidence question. Hold both to the same bar: named test methods, independent accredited labs, and linked reports for efficacy, safety and stability. Evaluate the data, not the category label.
