Can You Put the Word Natural on a Cosmetic Label

Somebody always wants "all natural" on the front of the label before they've even finished the formula. Fair enough, it sells. But it's worth slowing down on this one, because the word does a lot of persuasive work while carrying almost no fixed regulatory definition behind it.

No fixed line to check against

There's no single, official regulatory threshold in Canada that spells out exactly what percentage of a formula must come from unprocessed plant or mineral sources before you're allowed to call it natural. That's different from something like a fragrance allergen threshold, where there's an actual number to check your formula against. With "natural," you're making a claim you need to be able to defend with your own reasoning, not one you're clearing against a published bar.

What buyers assume the word means

Even without a legal definition, shoppers bring their own expectations to the word. Generally that means minimal processing, recognizable plant or mineral origin, and an absence of synthetic additives. If your formula technically qualifies under some narrow reading but still contains heavily processed synthetic preservatives or lab-derived actives that a typical customer wouldn't associate with "natural," you've got a gap between the claim and the expectation it creates. That gap is where complaints and reputational damage live, even if no specific rule was technically broken.

Where this gets genuinely tricky

A few common gray areas:

• Naturally derived versus natural. An ingredient that starts from a plant source but goes through significant chemical processing to become the final INCI-listed material is a different claim than something minimally processed. Conflating the two is a common shortcut that doesn't hold up under scrutiny.
• Preservative systems. Most functional, broad-spectrum preservative systems are synthetic, for good reason, they work reliably. A "100% natural" claim next to a synthetic preservative on the ingredient list is an inconsistency a sharp customer, or a competitor, will notice.
• Trace processing aids. Solvents, stabilizers, or carriers used during ingredient manufacturing that don't end up meaningfully in the final product complicate a strict "natural" claim, depending on how strictly you and your audience interpret the word.

A more defensible approach than "100% natural"

Rather than reaching for the broadest possible version of the claim, consider being specific about what's actually true:

• "Made with naturally derived surfactants" instead of an unqualified "natural" claim covering the whole formula.
• Listing the percentage of plant-based or naturally sourced ingredients if you can actually calculate and stand behind that number.
• Being upfront that a preservative is included and is synthetic, because informed customers increasingly read that as honest rather than as a mark against the product.

A simple comparison

Claim Style	Defensibility	Risk
"100% Natural"	Low, unless truly free of all synthetic components	High, easy to contradict with the ingredient list
"Naturally derived ingredients"	Moderate, if you can explain sourcing	Lower, more precise
"X% plant-based formula"	Higher, if the number is calculated and documented	Low, specific and checkable
No natural-adjacent claim at all	Highest	None, but loses the marketing angle

The label and the ingredient list need to agree

Whatever claim you land on, it has to survive a customer, or a regulator, reading your actual INCI ingredient list side by side with your marketing copy. If the front of the package says natural and the back lists several ingredients with clearly synthetic-sounding INCI names, that mismatch is the actual risk, more than the word itself.

The takeaway

"Natural" isn't banned and it isn't automatically deceptive, but it's an unregulated word carrying a lot of implied meaning, so use it with a specific, honest claim behind it rather than as a blanket descriptor you haven't actually checked your formula against. Since expectations and enforcement around this kind of claim can shift, it's worth periodically checking current guidance rather than assuming last year's label copy is still the safest phrasing.

When you're mapping out a formula for filing, Cosmetic Comply surfaces exactly which ingredients are synthetic, naturally derived, or plant-origin at the INCI level, which is a useful gut check before you commit to natural-adjacent label language.
