An eye contour product with UV filters looks like a small version of a face sunscreen, & that assumption is where most of the trouble starts. The area is roughly the size of a coin, the pack is small, the quantity a user applies is a fraction of what a face product receives, & the item often sits under concealer for the rest of the day. Each of those facts changes the brief, & none of them is captured by pouring a face formula into a smaller tube.
There is a category question underneath as well. In some markets a UV product is handled as a cosmetic, in others it sits in a separate category with its own route to market, & the same formula can be regarded differently depending on how it is presented & worded. That decision belongs at the start of the project, because it fixes the testing, the dossier & what the pack is allowed to carry.
This article covers the decisions that come before a sample: the market, the wording, the filter screen, the texture on thin skin, the pack, the filling tolerance of a small volume & the evidence behind whatever goes on the label. It is written for a brand that wants a defensible item rather than a fast one.
Start with the market & the wording, not with a filter list
Buyers usually open with filters, because filters are the visible part of the category & the easiest thing to research. The order of decisions that works is the reverse: destination markets first, then the category the item will sit in, then the wording the pack will carry, then the filter screen, & only then the base. Working in that order removes most of the rework that follows a sunscreen brief.
A daily eye contour used under makeup in a warm, humid market asks for a light, non-tacky film & a comfortable application on thin skin. A face product intended for a beach holiday asks for a heavier film, a different wear profile & a different pack. Those are two briefs, not one brief with two sizes, & a brand should say which one it is selling before anything is mixed.
Writing the wording early has a second benefit. The statement on the pack has to rest on what a laboratory actually measured, & the measurement route differs between markets. A brand that leaves the wording to the artwork stage usually ends up rewriting both the artwork & the claim, at a point when the batch is already committed.
Permitted filter lists & why the eye contour narrows the choice
Every market keeps a list of permitted UV filters with conditions on how each may be used, & a filter that is routine in one region can be restricted or absent in another. Some markets also add labelling duties for particular material types, which is why the same formula can carry two different packs in two different destinations.
Mineral filters are chosen often for products near the eye because they tend to be well tolerated, but they bring opacity. On thin skin a mineral film can read as white, & the particle grade & surface coating change both the feel & the tone. A brand that wants the tolerance of a mineral system & the finish of an organic one has to accept a compromise somewhere.
Organic filters dissolve in the oil phase & make their own solvent demands, which shapes the emollient choice from the first version of the formula. A base built for one family does not quietly accept the other, so the brief should state which family the brand is open to rather than leaving the factory to guess. Guessing produces a sample that meets the chemistry & fails the brief.
Filter load & the texture budget on a small pack
The filter load sets the texture budget. Above a certain point the product drags on the lid, & drag is felt most keenly around the eye, where the skin is thin & the movement across it is short. A user who feels resistance stops spreading & starts dabbing, which produces an uneven film & a poor impression of the product regardless of what the chemistry delivers.
Small packs carry their own economics. A 10 ml or 15 ml container reads as a considered, eye-specific item on a shelf, but the pack cost per millilitre is far higher than on a 50 ml face product, & the filling time per unit is similar, so the unit price is driven by the pack & the line rather than by the bulk. Brands comparing a small eye item with a face product on cost alone usually compare the wrong numbers.
Filters are also a large share of the oil phase, so they take up room that emollients would otherwise occupy. Every point of load spent on protection is a point not spent on slip, cushion or dry-down, & the balance is what a brief is really asking the formulator to solve. Stating which of the two matters more for the launch removes a whole round of samples.
Photostability, film & the applicator
Some organic filters change under light, & a formula either stabilises them with partner materials & antioxidants or accepts a different performance profile over the day. This is a bench decision rather than a labelling decision, & it is one reason two products with similar filter lists can behave differently after an hour in the sun.
The applicator decides how even the film is. A stick drags across thin skin & can deposit too much in one pass. A rollerball with a metal ball applies a thin, uneven line & its ball holds residue between uses. An airless pump with a small nozzle meters a consistent dose, which is the easiest route to a repeatable application & usually the most expensive pack.
Layering matters more here than on the face because the item is often worn under concealer. A film that pills, slides or shifts when the next product goes on top will be reported as a bad product even if the UV behaviour is sound. The check is simple: apply the eye item, wait, apply the concealer, & look at the result after an hour rather than after a minute.
How a protection value is established & what the pack may carry
A protection value is produced by a laboratory method, either on volunteers or by an agreed alternative, & it is an output of that work rather than a property the factory sets on the bench. Nothing in this article states a figure, a threshold or a limit, because those come from the specific method used, the market's rules & the finished formula as tested. We do not publish testing conclusions for a product that has not been tested.
What can be said is bounded on both sides. A brand may state the value a test produced, in the wording the destination market permits, & it may use descriptive language the market allows. What cannot be said is anything that implies a medical benefit, anything absolute such as total or complete protection, & any grade or value the testing did not support. Wording that presents the product as a way of addressing a condition is the fastest way to turn a cosmetic item into a regulatory problem.
The practical rule is to ask the factory what testing it can arrange & what the result is able to support, then build the label wording from that answer. A claim written before the testing exists is a liability, because the gap between the hoped-for result & the measured one is exactly where market surveillance & marketplace review teams look first.
Water resistance & wear wording: what can be said
Water resistance is a separate test & a separate statement. It is not implied by a filter system, by a high filter load or by a base that feels water-repellent on the hand. Where a market regulates the wording, the claim is available only on the basis of the specific method that market recognises, & the brand has to decide whether the cost of that work is worth the wording it unlocks.
Sweat & humidity behaviour is harder to pin down, & several markets restrict how a product may describe it. For an eye contour the more useful question is often comfort rather than resistance: does the film migrate into the eye, does it make the lid feel tight, does it leave a residue on the lashes? Those are user-experience questions that a small applied panel can answer before a claim is written.
Wording such as does not sting the eyes or suitable for contact lens wearers needs a documented basis, & in some markets the terms are defined or restricted. The safe approach is to keep the pack to statements the brand can evidence, describe the format & the use occasion, & leave the strongest wording until the reports exist.
Filling a small format accurately
Fill accuracy becomes visible at small volumes. A deviation of a fraction of a gram is irrelevant in a 200 ml bottle, but it is material in a 10 ml tube, where it can move the declared net content outside tolerance. Specify the fill weight with a tolerance, state how it is checked on the line, & confirm whether the declared content accounts for the product left in the nozzle after the first use.
Priming loss is the detail most often missed. An airless pump needs a priming volume before it delivers anything, & on a small pack that volume can be a noticeable share of the contents. The brand should decide whether the declared net content reflects the dispensable amount or the filled amount, because the two differ & the choice affects what the label may state in some markets.
Order volume is driven by the pack rather than by the bulk. Tube printing, sleeve or label minimums & the filling line setup are fixed costs, so a small run spreads them over few units. The bulk itself may be economical at a low weight, which is why a brand can sometimes order a smaller quantity of a small item than of a large one & still meet the supplier's minimum.
Stability, pack & the tube or airless decision
Light & air are the two things a UV formula is trying to resist, & a small pack is often the most exposed. A clear tube left on a bathroom shelf lets light through for months; an opaque tube reduces that exposure; an airless pump reduces contact with oxygen as well. The pack belongs in the stability plan rather than in the design conversation alone.
Label real estate is the constraint that surprises brands late. A 10 ml tube has very little printable surface, & the ingredient list, the content declaration & any market-required statements all have to fit on it, often in more than one language. Where the surface cannot carry everything, the brand has to choose a larger pack, a secondary carton or a different format, & that choice is cheapest when it is made before the artwork.
Compatibility closes the loop. Filters & the esters that carry them can interact with certain plastics, with the elastomer inside a pump & with the gasket in a cap, & the interaction can show up as swelling, discolouration or a change in the bulk over time. Storing the finished formula in the actual component & inspecting it after accelerated storage is the step that catches this before a production run.
Eye contour UV formats compared
The table below sets out the formats a small eye contour item usually takes, the channel each one suits & the cost direction each brings, so a brand can see the shape of the trade before a sample is made. It is a sourcing map rather than a claim table, & what any format is permitted to state depends on the market & on the testing behind it.
| Format | Where it fits | Cost direction | What to watch |
|---|---|---|---|
| Light eye cream with a low filter load | Daily routine add-on sold with a face cream | Moderate | Wording must match what the testing supports |
| Mineral-only contour cream | Sensitivity-first positioning | Moderate to high | White cast on thin skin; even spreading takes practice |
| Tinted mineral contour | Coverage plus UV filters in one step | Higher, with shade work | Shade range & batch-to-batch colour control |
| Stick or balm format | Touch-up on the move & travel sets | Higher unit cost | Deposit is uneven; drags on the lid |
| Airless pump fluid | Light daily wear under makeup | Higher pack cost | Small nozzle can clog; priming loss on a small fill |
| Dual-use face & contour product | Brands that want one item in the range | Lower cost per unit | Wording has to hold for two areas of use |
| Rollerball with a metal ball | Cooling application & eye-specific ritual | Low pack cost | Uneven film; residue held on the ball between uses |
| Sachet or travel duo | Sampling, gifting & travel retail | High filling cost per unit | Fill accuracy at very small volumes; almost no label space |
The rows are a starting map rather than a recommendation. The same format behaves differently in two factories because the emollient, the emulsifier & the pack around it differ, which is why the texture target & the layering behaviour belong in the brief & are confirmed on a sample rather than assumed from the format name.
What to put in the brief
Write the brief so the factory can screen filters & propose a base without a questionnaire coming back. The markets come first, because they fix the permitted list, the route to market & the labelling duties. Then the intended wording, the format, the texture target, the pack & the volume, because each of those narrows the formula space before a single mix is made.
- The destination markets, & whether the item is filed as a cosmetic there or under another category.
- The wording you intend to put on the pack, & the use occasion behind it.
- Whether the base must be mineral, organic or open to either family.
- The texture target, & how the item layers under the makeup your buyers use.
- The pack type & the net content you want to declare.
- Whether a water resistance or wear statement is required, & who arranges that testing.
- The shelf-life target & the storage conditions the label will claim.
- The first order volume, & the smallest run the pack supplier will accept.
Then agree the testing sequence & the sampling sequence together, because they run in parallel rather than one after the other. A sensible path is one base sample to confirm texture & layering, a second sample to confirm the version that testing will be run on, & a golden sample retained by both sides before the first production order. Briefs that skip the middle step tend to send a sample for testing that changes afterwards, & the data no longer describes the product being sold.
Where our capability fits
We take a small UV item from the market list & the intended wording through to a sampled base & a tested formula. Filters are screened against the destination rules before the first mix, the emulsion is built around the filter load on our lines, & the order of addition is documented so that batch two matches batch one by reference rather than by memory. Small-volume filling runs against a written fill tolerance, & a retention sample is kept from every batch.
We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, & we say at the brief stage which testing we can arrange ourselves & which has to go to a specialist laboratory. Our adjacent lines include a firming face cream, a hyaluronic acid serum capsule range & a moisturising face serum oil capsule, all produced with the same batch record & retention discipline.
Tell us the markets, the pack & the wording you have in mind, & we will come back with a filter-screened base proposal, the testing route it implies & the label wording the result is likely to support.
