The Cosmetic Product Information File: What Goes In and Who Holds It

Most brands new to export regard the cosmetic product information file as a box they tick once, then forget. The trap is that the file is held rather than filed with an authority in the main market systems, & it is opened only when a regulator or a retailer asks a direct question. A brand that cannot say who holds its file, or whether the safety assessment inside it is current, is exposed in exactly the situation it hoped to avoid.

This article walks through what the file actually contains, who is expected to hold it, where the factory's documents stop & where the brand's own duties begin, & how long the file must stay available. Read it before you brief a manufacturer on a new market, because the depth of the file changes the documents you must ask for at the brief stage rather than after the artwork is approved.

What the file is for, & why holding it is not the same as filing it

A product information file is a structured dossier that supports a cosmetic placed on the market. In the European system it sits with the responsible person, in the United Kingdom with the UK responsible person, & it is the single place an authority looks when it asks how a product is safe, what it contains & what evidence backs its claims. The file is not submitted for approval in advance in those systems; it is produced on request.

The practical difference between holding & filing matters because it changes who is responsible for keeping it current. A manufacturer can supply the technical pieces, but the duty to hold a complete file usually rests with the entity that places the product on the market under its name. A brand that assumes the factory holds the file for it is often wrong, & it discovers the gap only when a market question arrives.

For a buyer the first task is therefore administrative before it is technical. Name the holder, confirm that person or function can keep the file for the required period, & confirm the file can be produced in the language the market expects. None of that is glamorous, but it is the part most often missing from a launch plan, & a missing holder is the fastest route to a failed audit.

The file also has a second life after launch. Authorities sample products for surveillance, retailers ask for it during supplier onboarding, & a serious complaint pulls the same documents into view. Regarding the file as a launch formality rather than a live obligation is the mistake that turns a routine request into a scramble.

Who is expected to hold the file: the responsible person

In the EU the responsible person is the natural or legal person who ensures the product complies with the rules & who holds the file. That person may be the brand, its distributor, or an appointed representative established in the market. The key point is establishment: a person or company outside the market cannot usually serve, which is why an importer or a nominated agent is used.

The United Kingdom runs a parallel duty with a UK responsible person. A brand selling into both markets needs a holder in each, & the two files should agree on the formula, the claims & the safety basis even when the appointed holders differ. A mismatch between the two is a finding on its own, because the product is the same but the evidence behind it should be identical.

China works differently: the registrant or filer submits a dossier & holds the underlying evidence, & the obligation sits with the applicant rather than with a separate responsible person. A brand using a local filer should confirm in writing who retains the evidence & for how long, because the answer decides who can answer a question two years later. The document discipline is the same even when the role has a different name.

The common thread is that the holder is answerable for information the brand did not generate. The factory may have made the product, but the brand is the one the authority asks. That is why the supplier document set is part of the product rather than an accessory to it, & why the brief should name the holder before the formula is mixed.

The composition section: qualitative & quantitative

The first substantive part of the file is the qualitative & quantitative composition. Qualitative means the ingredients by name; quantitative means the concentration or the concentration range for each. The range is acceptable where the formula is a base that the brand tunes, but the range must be the real range the batch can fall inside, not a placeholder that cannot fail.

For a brand sourcing a proven base, the quantitative part is mostly supplied by the factory as the formula with its version. For a custom development the brand should expect the concentration of each component to be stated with enough precision that a safety assessor can work from it. A vague list of an active blend without amounts is not a quantitative composition, & an assessor cannot assess a name it cannot identify.

The INCI names belong here, & so do the functions where the market asks for them. Fragrance compounds are listed as such, with the supplier's identifier, rather than broken into every component unless the component is individually flagged. A brand should confirm the factory supplies the full INCI list with the trade names resolved, because the file is only as good as the names it contains.

One detail that catches exporters is a colour or a preservative present at a level the market limits. That actual concentration must be in the file, not an estimate. Where the brand later changes the fragrance load or adds a pigment, the composition section must follow, or the file stops describing the product on sale. The update duty is where most files quietly fall behind.

The manufacturing method write-up buyers overlook

The method of manufacture is a shorter section than brands expect, but it is the one most often missing from supplier packs. It describes how the product is made at a level the assessor needs: the type of process, the critical parameters & the controls that keep the batch inside specification. It is not a full batch record, but it must be enough that the process is understood by someone outside the plant.

A factory that runs a documented process can produce this quickly. A factory that works from a formula card without a written method cannot, & the gap becomes the brand's problem at assessment time. The useful question at the brief stage is whether the manufacturer can supply a process description that an outsider could follow, not just whether the product can be made.

The section also covers the site & the quality position. Good practice is to state where the product is made & under what quality system, with the applicable certificate available on request. A brand should not claim a certification the factory does not hold; it should instead record the category of certificate the factory can show, & ask whether that certificate is current before it appears in any market copy.

Where part of the work is subcontracted, the method section should say so. Printing, filling at a second site, or assembly by a third party changes what the brand can promise about control of the process, & the file should reflect it rather than imply a single seamless line. A hidden subcontractor is the kind of gap an authority finds first.

The safety assessment & the assessor behind it

The safety assessment is the part a non-specialist brand cannot write. It is a document, prepared by a qualified assessor, that concludes the product is safe under its intended use. The assessor's credentials & the basis of the assessment belong in the file, & the assessment must cover the formula, the packaging, the use & the population exposed.

For a buyer the test is not whether an assessment exists but whether it covers the actual product. An assessment written for a base before the brand added a fragrance, a pigment or a higher active load is out of date the moment the formula changes. The brand should ask that the assessment names the formula version it covers & the date it was issued, so the file shows a clean line from formula to conclusion.

The assessment also depends on data the factory supplies: purity, impurity profiles, the toxicological position of each component. Where a raw material comes through a trader & the upstream data is thin, the assessor works from less, & the brand should know that before it prints a benefit that leans on an ingredient it cannot fully document. Honesty about the data chain is cheaper than a claim it cannot support.

A common error is to regard the safety assessment as a one-time cost. It is a living document that must be revisited when the formula, the pack, the market or the claim changes. Building that review into the quality agreement is cheaper than discovering the old assessment no longer fits at renewal time, when the artwork is already printed & the stock is already in a warehouse.

The claim substantiation held inside the file

Every claim a brand prints needs a basis, & that basis sits in the file. A claim that a product moisturises, refreshes or softens is descriptive & usually supported by the formula, but a claim that implies a measured outcome needs a study or a recognised method behind it. The file should hold the study, the protocol or the reference that supports each wording used.

The trap for exporters is the wording that travels differently across markets. A phrase that is descriptive in one region implies a specific result in another, & the substantiation expected follows the stricter reading. A brand should list the claims it intends to use & confirm the file holds support for each before the artwork is fixed, because removing a claim late is cheaper than defending one without evidence.

Where a brand uses a proven base & adds only packaging & a name, the substantiation from the base may carry across, but only if the base supplier's evidence covers the exact product & the exact wording. Assuming it does without checking is how a claim survives sampling yet fails a market review, & the cost of that failure is a relabelled run rather than a quick edit.

The file should also note where a claim is not supported, so the team stops reaching for it. A short internal list of approved wording, held with the dossier, prevents a copywriter from inventing a sentence that the evidence cannot back, & it keeps the brand out of the category of findings that begin with a single unsupported phrase.

Labelling & the artwork as part of the file

The label is not separate from the file; it is the consumer-facing half of it. The file should hold the current artwork, the list of ingredients, the warnings, the batch code format & the period after opening, so that what the assessor approved is what the customer sees. A mismatch between the approved label & the printed label is a finding on its own, even when the formula is sound.

This is where translation & market-specific fields bite. A label that omits the country of origin, the responsible person's address or a market-mandatory warning is incomplete even when the formula is correct. The brand should confirm the artwork in the file matches the market, not a generic export version that was good enough for the first shipment.

For a brand using a single base across several markets, the artwork may differ per market while the formula stays the same. The file should hold each version, & the brand should track which label goes with which consignment, because a warehouse mix-up puts the wrong label on the wrong market & turns a paperwork error into a compliance one.

The practical habit is to regard the artwork as a versioned document, like the formula. Each change, even a wording tweak, should be recorded with the date & the reason, so the file shows a clean line from assessment to shelf. A label that drifts from its approved version is the quiet way most files become inaccurate.

Where supplier documents fall short

Factories supply most of the technical content, but they rarely supply all of it. The usual gaps are the raw material certificates with real lot values, the stability data on the finished product, the fragrance allergen declarations & the full toxicological set for minor components. A brand that assumes these arrive automatically is disappointed at assembly time.

The raw material certificate is the most common gap. A distributor's certificate often restates the grade specification rather than testing the lot, so the quantitative composition leans on paper rather than measurement. A brand should ask, at the brief stage, which certificates will be per lot & which will be periodic, & price the difference in lead time before the launch date is fixed.

Stability data is the second gap. A factory may have accelerated data on the base but no real-time data on the finished product in its actual pack. The shelf life the brand claims should follow the data it actually holds, & the file should say which kind of data supports the claim rather than implying a longer life than the evidence allows.

The cheapest way to close these gaps is to name them early. A brief that lists the documents required, with the format & the language, turns a vague request into a specification the factory can meet, & it prevents the late discovery that a needed certificate cannot be issued at all by a supplier that was otherwise perfectly capable.

How long the file must be kept, & who updates it

The retention period runs from the time the product was last on the market, & it is longer than most brands expect. A brand planning to exit a market should not destroy the file the month it stops selling, because a question can arrive years later about a batch still in use or still in storage with a customer.

Updating the file is a duty, not a courtesy. Every formula change, pack change, claim change or market addition should trigger a review of the affected parts. The brand should assign the update to a named function rather than leaving it to whoever remembers, because the gap between a change & its reflection in the file is where findings happen during a routine check.

For a small brand the holder is often the founder or a single manager. That is workable while the range is small, but it is fragile: if that person leaves, the file can go with them. Recording the holder & a backup in the quality agreement protects the brand when the team changes, & it keeps the obligation from becoming a personal dependency.

A simple register that lists each product, its file location, its version, its holder & its next review date turns an invisible obligation into a manageable list. Most brands that fall behind do so because no one owned the list, not because the work was hard, & a spreadsheet reviewed each quarter closes most of the risk.

What happens when the file is tested

The file is usually tested in one of two ways: a routine authority request, or a specific incident such as a complaint, a recall or a competitor challenge. In both cases the authority asks for the file or parts of it, & the brand must produce it within a short window. A file assembled from incomplete supplier documents fails at exactly that point, regardless of how good the product feels in the hand.

The incident case is the harder one. A safety question about an ingredient, a contamination report or a labelling dispute all lead back to the file, & the brand must show the composition, the assessment & the substantiation on demand. A brand that cannot produce the safety assessment quickly is answering a technical question with silence, & silence reads as a missing file.

The routine case is more common than brands think. Market authorities sample products & request the supporting file as part of surveillance. A brand that regards the file as a launch formality rather than a live obligation is caught out by a request it did not expect for a product it launched two years earlier, with a formula that has since changed twice.

The preparation that works is to rehearse the worst case once: pick a product, ask the holder to produce the full file in a day, & note where it stalls. The stalls are the gaps to close before they matter, & they are usually the same supplier gaps described earlier, which means the fix is known before the pressure arrives.

What the file needs, what the factory supplies, & where the brand fills the gap

The table below sets the main parts of the file against what a manufacturer typically supplies & where the brand must add its own work. It is a division of labour rather than a blame list, & the point is to name the gaps before launch rather than during a request that allows no time to close them.

The rows are a division of work, not a fixed rule, because some factories supply more than others & some brands ask for less. The value is in naming, before launch, which row the brand will own, so the file is complete on the day it is first requested rather than rebuilt under pressure.

What to put in the brief

Raise the file at the brief stage, because the documents it needs change the questions you ask the factory. State the markets, the holder inside your team & the claims you intend to print, & confirm the factory can supply the technical pieces in the language each market expects. A brief that omits the file is a brief that will be rewritten later.

• The markets the product will sell in, & any planned within two years.
• The formula or base, & whether it is a proven base or a new development.
• The claims you intend to print, & the study or method behind each one.
• The responsible person or holder, & proof of establishment in each market.
• The raw material certificates needed, per lot or periodic, & the lead time.
• The shelf life you will claim, & whether real-time data will exist first.
• The retention period, & who holds the file if the team changes.
• The review trigger for formula, pack or claim changes, & who owns it.

Then fix the review rhythm. A file reviewed at each change & once a year afterwards stays current without a scramble. The cost of holding it is small; the cost of not having it on the day it is requested is not, & the difference is mostly discipline rather than money.

Where our capability fits

We supply the technical core of the file for every order: the formula with its version, the INCI list, the process description, the raw material data & the batch records, & we can produce them in the language a market expects. Where a material comes through a trader & the upstream evidence is thin, we say so at the brief stage so the brand knows what its assessment can lean on.

We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, & the file depth is agreed before sampling rather than after. Our lines include custom cosmetic softgel capsules for face serum & hyaluronic acid serum capsules, both produced with the same document discipline the file requires.

Tell us the markets you sell into & the claims you intend to print, & we will come back with what we supply, what your responsible person must hold & where a gap needs closing before launch. Start at our inquiry page, email capsulebiotech@163.com, or message the right team on WhatsApp: Capsule Series (capsules only) +86 158-7655-5319, Cosmetics Series (serum, hair care, body care, fragrance) +86 158-7655-5319. The document set brands usually need is set out in our guide to OEM documents, & the recording duty in our traceability article.

General manufacturing information, not regulatory or legal advice. Product information file contents, responsible person duties, retention periods & notification routes vary by market, & the applicable requirements should be confirmed for each destination before a product is placed on sale.
