Sunscreen and SPF Claims Across Markets

Why the protection value is the smallest part of the problem

Buyers new to sun care usually brief a number, then read everything printed around it as decoration. In practice the number travels better than the wording that sits next to it. A finished sun care product is judged on four separate statements at once: the protection value, the breadth of protection implied by the spectrum claim, the resistance claim if the product carries one, & the usage instructions on the back panel. Each of those is defined, tested & worded differently from one destination to the next, & all four have to line up before the artwork is signed off.

The practical consequence is that the formula is rarely the only thing that changes when a product moves between markets. The label is rewritten, the entity named on the pack changes, the test laboratory may have to be a different one, & the rating printed beside the value can disappear entirely because the destination does not use that system. Brands that plan one pack for every market lose the most time here, because the artwork is what has to be rebuilt after the claim set is settled rather than before.

This article covers what can be said, what usually cannot be said without a defined test behind it, & which questions belong in the brief so that the artwork is built once rather than twice.

What the protection value measures, & what it does not

A protection factor is a laboratory measurement of how much ultraviolet exposure a protected site tolerates before a defined reaction appears, compared with an unprotected site. It is a ratio produced under controlled conditions, on a panel of volunteers, with a fixed application rate, & it describes one part of the ultraviolet range far better than the other. It is not a measure of how long a person can stay outside, & it is not a measure of how well the product behaves on a hot beach after two hours of swimming.

Two consequences follow for anyone briefing a formula. The first is that the application rate used in the test is generous compared with what a consumer actually applies, which is why every market expects some form of reapplication instruction on the pack. The second is that the value relates to the finished formula in the finished pack, so a change of filter level, a change of preservative system or a move from a tube to a pump can put the tested value out of date. Asking whether a proposed change is cosmetic or claim-affecting is one of the most useful questions a brand can put to a factory.

It is also worth being clear that the value is not a ranking of quality. Two products carrying the same printed figure can behave quite differently in use, because of how they spread, how they sit on skin, & how quickly they are removed by water, sand or a towel.

The claim vocabulary: value, spectrum, resistance, category

Four families of wording appear on sun care packs, & each one rests on a different kind of evidence. The protection value rests on a test with human volunteers. The spectrum claim rests on a defined measurement of how protection is distributed across the ultraviolet range, & the way that breadth is expressed differs between markets: some use a letter & number rating, some use a threshold figure, some use a star scheme, & some accept a statement in words. The resistance claim rests on a protocol that involves immersion. The category wording, meaning whether the product is presented as sun care, as a day cream with protection or as a tinted base with protection, determines which of the other three families even applies.

The trap is mixing families. A brand that prints a spectrum rating bought from one testing route, a value measured under a different protocol & a resistance claim supported by nothing at all has produced a pack that will not survive a marketplace review in any market. A reviewer does not need to inspect the formula to see the mismatch; only to compare the claims against the documents.

Terminology also matters more than most buyers expect. Words that read as stronger protection have been removed or restricted in several markets over the years, & a phrase that was acceptable on a 2019 pack is not automatically acceptable now. Because these lists change, the safer order of work is to build wording from the reports that exist, rather than to choose wording first & look for evidence afterwards.

Why the filter list decides whether a formula travels

Every market keeps its own list of ultraviolet filters that may be used, with its own maximum concentrations, & the lists do not match. A filter that is routine in one region may be unapproved in another, or approved at a level too low to reach the protection value the brand wants. This is the single most common reason a sun care formula cannot be sold unchanged across borders, & it is decided by chemistry rather than by paperwork.

When a filter has to be swapped, the consequences run through the whole product. The replacement may be oil-soluble where the original was water-soluble, which changes how the emulsion has to be built. It may bring an odour or a yellow tone with it. It may interact with the preservative system, with the fragrance or with the packaging. In an oil fill or capsule format the filter has to dissolve cleanly & stay dissolved across the shelf life, which is a different problem from suspending an inorganic filter in an emulsion.

The brief should therefore name destinations before sampling begins. A factory asked to quote a sun care product without destinations can only guess, & the guess is usually the filter system the plant runs most often, which is not necessarily the one the destination allows. Correcting that after the sample has been approved costs a reformulation, a second stability window & a second round of testing.

Testing routes, & what each one supports

Sun care testing is unusual among cosmetic tests because the classical route uses human volunteers rather than instruments alone. That shapes everything downstream: laboratory availability, panel size, timing, seasonal effects on scheduling, & the shape of the cost. It also means testing happens on the final article, in the final packaging, at the final filter levels, because anything else leaves the report describing a product that is not the one being sold.

Some statements can be supported by laboratory methods that do not involve volunteers, & some markets accept those methods for specific wording. Where a brand intends to rely on a non-volunteer route, the question to settle early is whether the destination accepts it, because a report that is acceptable in one market may be neither accepted nor transferable in another.

The documents that come out of testing matter as much as the result. A usable report names the method, the laboratory, the date, the panel characteristics, the reference standard used & the article tested, including its batch code. A one-page summary with a figure on it & nothing else is not a basis for a claim that will be examined. Buyers should also ask where the raw data sits & who holds it, because a brand that later changes laboratory or factory may need to reach back to it.

Water resistance & sweat wording

Resistance claims are the ones most often printed without support, because they are cheap to write & expensive to test. A resistance statement rests on a protocol in which volunteers are immersed for defined periods between exposures, & the result is expressed as retention of the original protection value rather than as a new figure. Because the protocol is defined, the wording that may be used alongside the result is also constrained in several markets, & the phrases are not interchangeable.

Sweat is a separate matter. A product may perform well under immersion & poorly under heavy perspiration, or the reverse, because the removal mechanisms differ. Some markets expect resistance to be described only on the basis of a defined test, & some do not recognise a sweat claim in the way a brand might imagine. Marketplaces & retailers add a second layer, since a listing that repeats a stronger version of a pack claim creates a record that is easy to evidence against.

Where the intended channel is sport, swim or family use, resistance is usually the claim that decides whether the product works commercially. A brand that wants it should fund the test rather than soften the wording, because softened wording on a beach product rarely converts.

Combination products: protection claimed on a cream, a base or a lip product

A tinted day cream, a foundation with protection or a tinted lip balm with protection is the most commercially attractive way into sun care, because the product then sells on colour or on daily care rather than on the beach. It is also where claim overlap causes the most trouble. Once a protection claim is made, the full claim regime usually follows: testing on the finished tinted article, careful wording about reapplication, warnings that do not fit neatly on a small pack, & a decision about whether the incoming filters include the inorganic grades that most often conflict with pigment systems.

The formulation work is different too. Inorganic filters are particulate, they scatter light, & they can shift the shade of a tinted base or leave a cast on deeper skin tones. Organic filters may need a co-solvent that disrupts the film giving the base its wear. The claim & the aesthetics pull in different directions, & the resolution is usually a compromise settled in sampling rather than in a brochure.

The commercial question to answer early is which claim is doing the selling. If protection is the reason the product exists, the shade range may have to accommodate it. If the shade is the reason, a modest protection claim with conservative wording is often the better trade.

Labels, warnings & the back of the pack

Back-of-pack text is where sun care projects lose weeks. Usage instructions, reapplication guidance, warnings about infants, warnings about eyes, storage notes & the ingredient list all compete for space, & several markets require the text in more than one language. Sun care packs are also among the products most likely to carry a fragrance, which brings the allergen declaration duty into play, & that declaration has to reflect the fragrance actually used rather than the fragrance as first briefed.

Two physical details that catch buyers out in other categories apply here as well. Alcohol-based products, including some sprays & gels, carry a flash point that determines how they may be shipped, which UN classification applies, & where they may be stored in a warehouse. Any product containing a fragrance carries its own allergen declaration obligation, & where the scent is built from several compounds the declaration has to be assembled from supplier documents rather than assumed.

The practical discipline is to draft the back panel at the same time as the front, using the test reports & the ingredient declaration as the source, & to read any front claim without a matching report as unfinished work rather than as a design choice.

Sprays, sticks & other formats: the extra duties

Format choice changes the compliance burden more than most brands expect. A spray is convenient in use but brings propellant or pump engineering, particle size considerations, flammability classification & freight restrictions. A stick is easier to ship & easier to apply at a defined rate, but the wax system has to hold the filters without sweating at high temperature, & the pack has to survive a car interior in summer.

A capsule or single-dose oil format solves some of those problems & creates others. The dose is fixed & hygienic, the fill is sealed from air, & the pack is light to ship, but the filter must dissolve cleanly in the fill & stay in solution for the whole shelf life. Fill weight accuracy then becomes a claim-relevant parameter rather than a cosmetic one, because the amount delivered per unit has to match the amount assumed in the test.

For all formats the instruction panel decides a lot of real-world performance. Whether the product is sprayed into the hand or directly onto skin, whether it is applied before or after a base, & whether the recommended amount is expressed in a way a consumer can follow, are all part of the claim as a reviewer reads it.

Children's & family sun care

Products positioned for children attract a stricter reading than adult products in most markets, & the extra caution applies to the wording as much as to the formula. Age thresholds, warnings about infants, claims about gentleness & claims about eyes are all areas where the acceptable vocabulary is narrower than the marketing instinct. A product can be formulated for young skin without carrying wording that suggests it is intended for infants, & that distinction should be settled at brief stage rather than at artwork stage.

The formulation usually moves towards the same place: a smaller filter set, a simpler emollient system, no strong fragrance, & a texture a parent can apply quickly to a moving child. None of that is difficult, but each choice narrows the claim set further, so the two decisions should be taken together.

Family positioning is the middle path many brands take: one pack, one texture, wording that avoids age-specific promises, & a protection value that suits the widest part of the range. It is less distinctive as a brand, & it is usually the cheapest route to a single artwork that works across several destinations.

The claim set against the question it raises

The table below sets the common sun care statements against the evidence they rest on, the point at which they usually break, & the question worth settling before sampling begins.

The entries are relative, not fixed values. Which wording is permitted, which rating applies, which tests are accepted & which text is compulsory all vary by destination & are revised from time to time, so the table is a planning tool for the brief rather than a substitute for confirming the requirement for each market before the pack is printed.

What to put in the brief

State the destinations first, because the filter list, the rating system & the label duties all follow from that line. Then state the channel, since a marketplace listing, a pharmacy shelf & a salon back bar are reviewed by different people against different standards. If the brand already holds a report for a related formula, say so, & say which laboratory produced it, because a report that can be reused shortens the schedule considerably.

• The destinations, including any market planned within a year.
• The protection value intended, & the basis on which it was chosen.
• Whether a spectrum rating, a resistance claim or neither is wanted.
• The finished format: emulsion, gel, spray, stick, capsule or tinted base.
• The pack type & the panel space available for mandatory text.
• Whether a fragrance is present, & who holds the allergen declaration.
• The channels the product will be sold through, & any retailer requirement beyond the market minimum.
• Whether the brand will hold the test reports & raw data, or expects the factory to.

Then agree the sequence. The useful order is destinations, formula, test, wording, artwork, & it is worth writing that order into the project plan so that nobody begins artwork while a claim is still open. A sun care launch is not slower than other categories because the formula is harder; it is slower because the claim set has to be settled before the pack can be designed.

Where our capability fits

We build sun care & sun-adjacent products as emulsions, gels, oil fills & capsule formats, & we coordinate the testing route a brand needs rather than issuing a figure that no report stands behind. At the sampling stage we will say which filter systems we can run, which formats suit the claim the brand wants, & which parts of the project have to wait for a destination decision.

We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, & the claim set is settled before stability & testing are booked. Formats we run in this category include a hydrating soothing face cream base, a moisturising oil capsule range & a mousse body wash format, all produced under the same batch record routine.

Tell us the markets, the pack & the claim you want to carry, & we will come back with what the formula can support, what has to be tested, & which wording should be dropped before the artwork is built.
