Choosing a Preservative From the Annex V Approved List

Every "why won't my natural preservative pass" question with an EU-bound product usually comes back to the same fact: you don't get to pick any preservative that sounds nice and safe, you pick from Annex V, and that list is a closed one.

Why Annex V exists and why it's closed

Under Regulation (EC) No 1223/2009, preservatives permitted in EU cosmetics are restricted to a specific approved list, Annex V, and each entry comes with its own maximum concentration and, in some cases, other conditions of use. This isn't a suggested-ingredients list, it's the entire universe of what's legally allowed to function as a preservative in an EU-notified cosmetic. If a substance isn't on it, you can't rely on it to preserve your product for the EU market, no matter how effective it is or how it's marketed elsewhere.

This matters because a lot of preservative marketing outside the EU leans on natural-sounding language, "plant-derived," "food-grade," "gentle broad-spectrum," that has nothing to do with whether the substance actually appears on Annex V. Effectiveness and regulatory permission are two separate questions, and only the second one determines whether you can use it in an EU-notified product.

What this means for a natural formula

Makers chasing a "clean" or "natural" preservation system often run into a real tension here. Some preservative options marketed as natural alternatives simply aren't on Annex V at all, and others are on the list but at concentrations that don't provide adequate broad-spectrum protection on their own, especially in water-rich formulas like lotions or gel cleansers.

Two things maker teams often have to accept:

• You may need a combination of two or more Annex V preservatives to get adequate broad-spectrum protection, rather than relying on a single ingredient. This is standard practice, not a sign of a poorly designed formula.
• The maximum permitted level under Annex V sets a hard ceiling. You can't compensate for a weak preservative system by simply using more of one ingredient past its allowed maximum. If your system isn't holding up at the permitted level, the answer is a different combination, not a higher dose of the same one.

Who signs off on this

This is exactly the kind of decision the Cosmetic Product Safety Report exists to document. A safety assessor reviewing your CPSR isn't just checking that your preservatives are individually on Annex V, they're evaluating whether your combination and concentrations genuinely preserve the specific formula you're selling, including its water activity, pH, and packaging. A challenge test, sometimes called a preservative efficacy test, is the typical way this gets demonstrated in practice.

A general shape of the table

Exact maximum concentrations and specific conditions of use for each Annex V entry change periodically and are genuinely worth checking against the current official Annex V text rather than a static table in a blog post, since amendments do happen. That said, the general categories to think about when you're picking a system look something like this:

Category	What to check
Parabens-family preservatives	Individual and combined maximum concentrations, and category-specific restrictions
Organic acids (e.g. benzoic acid, sorbic acid types)	Maximum concentration, often pH-dependent effectiveness
Formaldehyde releasers	Some are permitted with conditions; scrutinize carefully, some brands avoid this category on principle
Phenoxyethanol-type preservatives	Common broad-spectrum option, has its own maximum
Newer alternative preservatives	Check current Annex V status directly, since these entries update more often than older ones

The practical order of operations

1. Decide on your water activity and general formula type before you pick a preservative system, since that determines how much protection you actually need.
2. Cross-check every candidate ingredient against the current Annex V list and its maximum concentration, not against marketing language.
3. Build a combination if a single preservative doesn't cover the spectrum you need at permitted levels.
4. Get a challenge test done and have your safety assessor sign off through the CPSR before you notify via CPNP.

Cosmetic Comply is Canada-first today, with EU support coming, and preservative screening against a regulator's approved list is exactly the kind of check that's easy to get wrong by hand and much faster to verify with a proper ingredient-matching tool once that support lands.
