"Clean" is the most commercially powerful and legally emptiest word in the category. It sells. It also has no official definition in the United States, none in the European Union, and none in the UK. What actually constrains your formula is not a statute called clean — it is a stack of retailer restricted-substance lists, a fragrance-industry standard you probably have not read, and the false-advertising rules that turn a vague "free-from" badge into a liability.
This is a buyer-side guide to building a clean beauty and fragrance personal-care line through an OEM: what clean means in practice, where fragrance compliance really bites, which "free-from" claims are safe, and how to audit a factory that says it can do clean.
Clean has no legal definition — so the retailer list is the law
There is no government definition of clean beauty to comply with. Instead there are private standards, and they are the real gatekeepers because they decide whether you get shelf space.
The commercial order of operations is therefore: pick your target retailer first, get its restricted list second, and write the formula third. A formula designed only to satisfy federal law will fail a Credo screen, and reformulating after you have committed to packaging is the most expensive mistake in this category.
For context, in China the position is similar in one respect and different in another: "clean" is not a certification there either, but the regulatory floor is NMPA's ingredient catalogue and the labelling rules. The lesson generalises — in every market, clean is a marketing position validated by someone else's list, not a licence.
The EU floor: Annex II is the hard line, ISO 16128 is the vocabulary
If you sell into Europe, the legal minimum is unchanged by your clean positioning: full compliance with Regulation 1223/2009, a safety assessment (CPSR), a Responsible Person, CPNP notification and INCI labelling. Clean adds nothing to that and subtracts nothing from it.
Where ISO 16128 matters is language. The standard defines how to calculate natural, natural-origin and organic content indices. It is not a certification and it does not make a product "natural", but if you want to say "95% natural origin" on a European pack, ISO 16128 is the method a regulator or a competitor will expect you to have used. Ask your OEM whether it can produce the calculation, because most cannot without the raw-material data from suppliers.
If you want a genuine organic mark — COSMOS Organic, NATRUE or Ecocert — budget for dual certification: the formula and the manufacturing site. That typically adds 3–6 months and a per-certification fee to the programme, and it constrains permitted processes (no ethoxylation, limited solvent use, restricted petrochemical-derived ingredients).
Fragrance compliance: IFRA, EU allergens, and the US gap
Fragrance is where clean lines break. It is also the single largest source of dermatological complaints in personal care.
IFRA Standards are the global baseline. The International Fragrance Association publishes limits for individual fragrance materials across categories of product exposure, updated periodically (currently the 51st Amendment). A compliant fragrance house supplies, for every fragrance compound, an IFRA certificate of conformity stating the maximum level permitted for your product category, plus a per-batch COA. If your OEM cannot produce that certificate, you do not have a compliant fragrance — you have a scent.
The EU has expanded its declarable allergen list far beyond 26. The original 26 substances, declarable at 0.001% in leave-on and 0.01% in rinse-off products, have been extended to 80+ declarable fragrance allergens under Regulation 2023/1545, with new labelling and, in some cases, prohibition triggers. The practical consequence: the fragrance compound you used for a European body lotion in 2024 may need a reformulation and a reprint now.
The US currently allows "Fragrance" as a generic listing — but that is changing. MoCRA directs FDA to issue regulations on fragrance allergen disclosure, and FDA has proposed a rule that would require identified fragrance allergens to be named on cosmetic labels. Meanwhile, California's fragrance and cosmetic disclosure requirements already push in the same direction, and retailers increasingly require full disclosure regardless of what the law mandates.
Practical guidance: design every fragrance to IFRA category limits plus the EU declarable list, even for a US-only launch. It costs nothing extra at formulation stage and it keeps the SKU sellable everywhere later.
The free-from claims that get brands sued
"Free-from" is not a loophole — it is a factual claim that must be true, verifiable and not misleading. Here is how the common ones actually hold up.
The pattern is simple: the more specific the exclusion, the safer the claim. "No parabens" is a checkable fact about your formula. "Clean" is an opinion about your brand, and opinions are where advertising regulators live.
Factory scorecard: six things a clean-beauty OEM must be able to show
On point five, be precise. Cruelty-free is a supply-chain assertion, not a lab result. You need written attestation from every raw-material supplier and from the factory that no animal testing was conducted or commissioned. In the EU, the UK and a growing number of US states (California and New York among them), selling a product tested on animals is itself prohibited, so the attestation is also a legal document. Note also that China has moved significantly: since 2021 most general cosmetics no longer require pre-market animal testing, which makes a genuinely cruelty-free China-manufactured line achievable — but only if every input is documented.
Cost, MOQ and timeline
A quote that removes the 15–35% clean premium has usually substituted a conventional input somewhere. Ask the factory to list the specific cost additions rather than quoting a single blended number.
What consumers actually check
The clean consumer is not naive. In the US and UK, a meaningful share of buyers read the INCI list, look up individual ingredients, and compare a brand's claims against what is on the back of the pack. Three behaviours follow from that:
- "Clinically tested" has lost its power. Without the study design, sample size and endpoint, the phrase reads as filler. Publish the numbers or drop the badge.
- Named exclusions outperform abstract virtue. "No parabens, no phthalates, no SLS, no cyclic silicones" is more persuasive than "clean" because it is checkable.
- Fragrance is the first thing a sceptical buyer looks at. Publishing the full fragrance disclosure, including allergens, is now a competitive advantage rather than a risk.
FAQ
Is "0% added" legal?
It is legal only if it is true and specific. Vague "0 added" with no identified substance is treated as misleading in the EU and is vulnerable to an NAD challenge in the US. Always name what is not there.
Do I need COSMOS certification to sell as clean in Europe?
No. COSMOS is a private certification. The legal requirement is Regulation 1223/2009 compliance; ISO 16128 supports a natural-origin statement if you want one.
Can a fragrance personal-care product claim "calming" or "helps you sleep"?
Not as a physiological claim. Mood and sleep claims imply a therapeutic effect. Sensory and experiential language — "a warm, woody scent", "an evening ritual" — is defensible; "clinically reduces stress" is not.
Should I remove fragrance entirely from a baby or children's range?
Yes, or reduce it to a very low level. Paediatric lines are the one place where fragrance-free is both a safety decision and a marketing advantage, and it removes the entire allergen-labelling problem.
Can I use the same formula in the US and EU?
Usually, if you design to EU Annexes and IFRA limits and then adapt the label for allergen disclosure. Design the fragrance once, to the strictest standard.
