Colour Cosmetic Fragrance and Allergen Labelling

Why a low fragrance load still creates a labelling problem

Colour cosmetics are not perfume. A lipstick usually carries between 0.2 and 0.8 per cent fragrance, a pressed powder less than that, and a mascara or a brow pencil often none at all. Brands building a colour range reasonably conclude that fragrance allergen labelling belongs to the body care and fine fragrance teams, and that a matte lipstick sits outside the conversation entirely.

The conclusion is wrong, and the reason is the threshold rather than the dose. A fragrance compound dosed at 0.3 per cent in a leave-on product may itself contain one or two per cent of a regulated allergen as a constituent. That places 30 ppm of the substance in the finished product. The declaration threshold for leave-on cosmetics in the European Union is 10 ppm. The product is over the line by a factor of three, and the brand never chose to put the substance in the formula in the first place.

The practical consequence is that the fragrance level in a colour formula tells you almost nothing about whether an allergen declaration is needed. A lightly scented product can require a longer ingredient list than a heavily scented one, because a single compound arrived with an allergen already inside it while the other was built from materials that carry none. The question is a multiplication, not an impression.

Where allergens actually enter a colour formula

Most colour briefs assume there is one route in, which is the fragrance oil. There are four, and the other three are the ones that cause late artwork changes.

The first is the fragrance compound itself, whether that is a purchased oil or a development made for the brand by a house. The second is a natural complex substance: an essential oil, an absolute, a botanical extract or a flower water used for positioning reasons. A "rose" lip balm built on a rose absolute carries whatever allergens the absolute contains, and a vanilla-flavoured gloss built on a vanilla extract carries the same. The third is an ingredient that happens to contain the substance as a constituent without being a fragrance at all, such as a botanical extract added for a skin benefit or a carrier oil that has not been stripped of its volatiles. The fourth is an intentional addition: benzyl alcohol used as a preservative or a solvent, linalool used to build a specific note, limonene used to round out a citrus accord.

The difference matters because the routes are handled by different people. The fragrance house reports on its own compound and generally does it well. The botanical extract supplier reports on the extract's specification, which may not carry an allergen declaration unless the brand asks for one. An intentional addition sits in the formula sheet as an ingredient in its own right and is straightforward to see, but only if someone is looking at the whole formulation rather than at the fragrance line.

A colour formula tends to use more botanical extracts than a serum does, because the category leans on plant-derived pigments, oils and butters for both texture and story. That makes the second route more common in a lipstick than in a cleanser, which is the opposite of the assumption most teams start with.

The list grew from 26 to 82 and the arithmetic did not change

For roughly two decades the European Union required 26 named fragrance allergens to be declared individually when they passed a concentration threshold. Following a review by the Scientific Committee on Consumer Safety, the amending regulation added 56 more substances to the same framework, bringing the total to 82 entries that now sit in Annex III of the Cosmetics Regulation.

The important detail is not the number. It is that the new entries include constituents of naturally derived materials rather than only substances recognisable as perfumery raw materials, and that the list has been reorganised into a mix of standalone entries and grouped entries. A brand that built its ingredient-list logic around a fixed list of 26 names now has a list that behaves differently.

Three consequences follow. First, the composition of a fragrance compound has to be re-read against a longer list, not merely re-checked against the old one. Second, materials that had been regarded as outside the scope because they are natural, or because they are extracts rather than perfumes, are now inside it. Third, the threshold rules apply to the new substances in exactly the same way they applied to the original 26, which means no formula that was previously compliant becomes non-compliant through reformulation alone, but many labels do become incomplete.

This is a transparency measure rather than a safety restriction on the fragrance itself. No ingredient has to be removed and no scent has to be rebuilt. What changes is what has to be printed.

Thresholds, sources and the sum that decides the answer

The thresholds are unchanged from the previous regime. An allergen that is present above 0.001 per cent, which is 10 ppm, in a leave-on product has to be named in the ingredient list. The equivalent figure for a rinse-off product is 0.01 per cent, or 100 ppm. The calculation is done on the product as offered for sale, at the concentration a consumer would use, and not on the concentrate or the fragrance oil.

Almost every colour cosmetic is leave-on, which places the category on the stricter side of that pair. The exceptions are the cleansing and removing steps around it, a makeup remover, a cleansing balm or a micellar water, each of which falls on the rinse-off figure. A brand that produces a lipstick and a lip scrub is working with two different thresholds for the same fragrance dose, and the scrub benefits from the looser one.

Because the assessment is a sum, the contributions from every source have to be added before the comparison is made. If a formula carries the same substance from a fragrance compound, a botanical extract and an intentional addition, the three amounts are added together and the total is compared with the threshold. Taking the largest single source and comparing that alone is a common route to a missing declaration.

Two placement rules matter at the point of writing the list. Declared allergens sit at the end of the ingredient list, before the colourants, or in a separate sentence after the list. And where a substance is added intentionally as a cosmetic ingredient rather than arriving as a constituent of something else, it has to be named regardless of whether it reaches the threshold. That second rule catches more colour formulas than it catches serums, because the category uses more of these materials deliberately.

Grouped entries and the mistake that survives review

The reorganised annex contains a mix of standalone entries and grouped entries, and the grouping is where most errors survive a first review.

For a standalone entry, the individual name is declared once that substance passes the threshold. For a grouped entry, the group name is the one that has to appear once the combined concentration of everything in the group passes the threshold, even if only one member of the group is actually present. Writing the individual name instead of the group name is compliant-looking, reads correctly in a laboratory report, and fails a market surveillance check.

The grouping also interacts with how a fragrance is specified. A house may quote a compound by listing the individual constituents it contains, which is useful for the technical file but not enough on its own for the label. The brand needs to know which constituents belong to a group, what the combined total of that group is in the finished formula, and therefore whether the group name belongs on the pack.

This is administrative work with a technical edge, and it does not resolve itself. If the fragrance house supplies a high-level allergen statement without the group structure, the brand is left to work it out from the raw constituent list, which is where an experienced formulator adds value at the brief stage rather than at the print stage.

Documentation: what a fragrance house owes you

The label is downstream of the paperwork, and the paperwork is downstream of the fragrance house. Four documents determine whether a colour project can be signed off without a scramble later.

An IFRA certificate confirms that the fragrance meets the standards set by the International Fragrance Association for the product category it will be used in, and the certificate is category-specific, so a compound approved for a lip product is not automatically approved for a body lotion or the other way round. An allergen declaration lists every regulated allergen present in the compound and its concentration, which is the input the arithmetic in the previous section depends on. A safety data sheet covers handling, and a certificate of analysis covers what a specific batch actually contained rather than what the specification allows.

Then there is the file around the product. The cosmetic product safety report has to be refreshed when the labelling changes materially or when it ages past its review horizon, and the notification in the relevant portal has to be updated to match, whether that is the EU portal, the UK portal or a national scheme in another market. A label change that is not reflected in the notification leaves the product inconsistent with its own file, which is a finding on its own.

The realistic sequence is to request the allergen declaration at the sampling stage, not at the artwork stage. A house that has already quoted the compound for another project can usually turn it round quickly; a house that has to run an analysis adds days, and days at the print stage turn into obsolete packaging.

Colour cosmetic fragrance and allergen variables at a glance

Lip products, eyes and the exposure difference

Not all leave-on products are equivalent in practice, and the differences show up in how much scrutiny a listing attracts.

A lip product is the most exposed position in the colour category. The area is small, the product is reapplied through the day, and a proportion of what is applied is swallowed. That combination leads several markets to constrain lip formulations more tightly than the rest of the category, and it makes the lipstick the product where a supplier's paperwork is most likely to be requested. A vanilla or mint flavour added for taste is also a fragrance from a labelling point of view, so a product with no perfume at all can still carry a declaration.

Eye products sit at the other extreme on dose and at a similar level of scrutiny for a different reason. Fragrance in a mascara or an eyeliner is usually minimal or absent, because the region is sensitive and because the formula has other work to do. Where a scent is added, it is generally at a fraction of a per cent, which means the compound composition matters even more than usual and the arithmetic has to be done on small numbers.

A face powder occupies the middle ground. It is applied over a large area at a low film weight, which reduces the delivered dose, but it remains a leave-on product and the threshold is unchanged. The same applies to a setting spray, which is a leave-on product applied as an aerosol or a fine mist and is easy to overlook because it feels transient.

Fragrance-free, unscented and natural positioning

"Fragrance-free" and "unscented" are marketing positions, not regulatory statuses, and neither removes a product from the allergen framework.

A formula can be built with no fragrance compound at all and still require declarations, because an essential oil added for a botanical story, a floral water used as a base, or a botanical extract included for a skin claim will contribute the substances it contains. A mask or a cream positioned as fragrance-free because no perfume was added is exactly the product where this is missed, since the brief for that product was to avoid fragrance and the team stops thinking about fragrance at that point.

The same trap appears in natural positioning. A brand that replaces a synthetic fragrance with a blend of essential oils has not reduced its labelling burden, it has made the composition less predictable. An essential oil varies between harvests, so the allergen content of a natural complex substance moves within a range, and the declaration that was correct for the first batch may not describe the fifth.

The practical answer is to specify the declaration as a purchasing requirement. Any botanical or fragrance material used in a colour formula should arrive with a current allergen declaration tied to the grade being supplied, and the value used in the sum should be the top of the declared range rather than the middle. That costs a few ppm of margin and removes an entire class of late change.

Dates, artwork lead times and legacy stock

Two dates do the work in the European Union. New products placed on the market from 31 July 2026 have to carry the extended declaration, and products that were already on the market have until 31 July 2028 before non-compliant stock has to be off the shelf.

The first date is more demanding than it reads, because placement is assessed per unit rather than per product. A batch that leaves the warehouse after the date is a new placement, even if the product has been sold in that market for years. The practical effect is that a reprint of an existing range, not only a new launch, has to carry the updated list once the date has passed.

Artwork lead time is the constraint that decides whether a range makes the date comfortably. A colour range is usually several shades sharing a carton, a base label and a component set, and each affected shade needs its own ingredient list, its own print plate and its own proof. Adding an allergen to one shade in a family of twelve is not a one-line change, and the print run has a minimum of its own, which means non-compliant cartons can turn into waste.

The efficient approach is to build the extended declaration into the next planned reprint rather than to schedule a reprint for it. A range that is reprinted every eighteen months will reach the date through its normal cycle if the artwork is prepared in advance, and will miss it if the list is only reviewed when the deadline becomes urgent.

What to put in the brief

The brief that produces a clean outcome names the markets, the exposure class and the documentation expectation, rather than leaving all three to be discovered later.

List the markets the product will actually be sold in, and take the strictest one as the default design target unless there is a commercial reason to run separate packs. State which products in the range are leave-on and which are rinse-off, because that single classification changes the threshold that applies. Name the fragrance route: whether the scent is a purchased compound, a development for the brand, or a natural blend, and whether any botanical material is included for a non-scent reason.

Ask for the allergen declaration and the IFRA certificate as deliverables rather than as favours, and ask for them at sampling. Say who will own the sum, and make sure it is someone who can see the whole formula rather than only the fragrance line. If the pack carries a flavour or a botanical story, say so, since those are the two places where a declaration appears unexpectedly.

The eight lines below are the ones that decide how much of the work happens at brief stage and how much happens at print stage.

• The markets of sale, and the strictest one among them.
• The exposure class for each item in the range, leave-on or rinse-off.
• Whether the scent is a purchased compound or a development for the brand.
• Every botanical extract, absolute, essential oil or floral water in the formula, including the ones added for a non-scent reason.
• Any flavour on a lip product, since a flavour is a fragrance for labelling purposes.
• The allergen declaration and IFRA certificate for each fragrance and botanical input, requested at sampling.
• Who owns the sum across all contributing sources, and how the group structure is handled.
• The reprint cycle for the range, so the extended list arrives through a planned print rather than a forced one.

Then set the artwork schedule against the market dates rather than against the launch date. A range that is compliant at launch but not at reprint produces the same problem twelve months later with less time to solve it.

Where our capability fits

We build colour cosmetics with the fragrance and labelling route mapped at the brief stage, which means the allergen declaration, the IFRA certificate and the group structure of the compound are collected while the shade is still being developed rather than after the carton is printed. Fragrance load, list placement and the leave-on classification are fixed together, so the ingredient list and the technical file agree before a print run is committed.

We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing, and full custom formula development — whichever matches where your brand is today. Our lines include a colourful fragrance range, a long-lasting waterproof foundation and a solid essence stick format, all of which rest on the same fragrance documentation and pigment dispersion disciplines that a colour programme needs.

Tell us which markets the range is going into and how the scent is being sourced, and we will map the declaration route, the documentation set and the artwork sequence against your launch plan.
