Cosmetic Product Safety Assessor: What Qualifications Must a CPSR Signatory Hold Under Article 10?

A brand contacted us after an online marketplace suspended its listings. The formula was sound, the label was tidy, and the safety report ran to forty pages. It was signed by a company, with no individual named and no qualification stated, and the marketplace's compliance team had rejected it in about thirty seconds. That is now a common story, and it turns on a single sentence in Article 10 of Regulation (EC) No 1223/2009, carried into UK law and enforced through the Cosmetic Products Enforcement Regulations 2013, with enforcement powers under Schedule 5 to the Consumer Rights Act 2015. The sentence says who may carry out a Cosmetic Product Safety Report, and everything else in this article follows from it.

This guide covers what the qualification requirement actually says and how it is interpreted, what a compliant signature block looks like, what certified assessor means and does not mean, the competencies that matter above the legal floor, who checks signatures and when, what happens when a report fails the test, how to verify a report you already hold, the questions to ask before buying one, and a short worked example of the same product assessed twice. If you have never looked at the signature page of your own Cosmetic Product Safety Report, that is the place to start.

What does Article 10 actually require?

That the safety assessment be carried out by a person in possession of a diploma or other evidence of formal qualifications awarded on completion of a university course of theoretical and practical study in pharmacy, toxicology, medicine or a similar discipline, or a course recognised as equivalent by a member state. Three elements carry the weight. It must be a person, so a company cannot be the assessor. The qualification must be at university level and awarded on completion of a course of theoretical and practical study, so short courses, certificates of attendance and online diplomas without that standing do not qualify. And the discipline must be pharmacy, toxicology, medicine or similar, which in practice covers degrees in those subjects and closely related biomedical and chemical sciences with relevant toxicological content, but not cosmetic formulation or business qualifications however extensive the experience behind them.

What does a compliant signature block look like?

What does certified assessor mean?

It is an industry shorthand for a person who holds the Article 10 qualification and, usually, further professional training or registration in cosmetic safety assessment. It is a helpful description and it is not a licence: no body issues a cosmetic safety assessor certificate that substitutes for the underlying degree level qualification, and there is no register a brand can consult in the way it can for, say, a chartered engineer. That is why the word certified should always be followed by a question: certified in what, by whom, on top of which degree? Spectra uses the term to mean assessors who hold the qualifying university degree and work full time in regulatory toxicology, and we expect to be asked to evidence it. Any provider who cannot answer that question specifically is relying on the word doing work the qualification should be doing.

What matters above the legal floor?

• Practical toxicological competence. Sourced profiles, real margin of safety calculations, defensible exposure models rather than templates.
• Fragrance and botanical expertise. Expanding concentrates to constituents, applying IFRA categories, calculating allergen declarations under the expanded EU list.
• Product type specialism. Baby, eye area, sun care, hair colour and oral products each carry conditions a generalist can miss.
• Annex currency. The annexes change regularly and in different ways in Great Britain and the EU.
• Professional indemnity insurance. Evidence that the assessor stands behind the work.
• Willingness to explain. An assessor who can tell you in plain words why a fragrance was capped is one who did the calculation.

Who checks the signature, and when?

More people than brands expect, and usually at the worst moment. Trading Standards officers and OPSS check the signature page first when they request a Product Information File, because it is the quickest way to establish whether a report exists in law. Online marketplaces have built compliance teams that review safety documentation before listings go live or when a complaint arrives, and an unnamed signatory is an immediate rejection. Insurers reviewing a reaction claim look for the qualified signature, because it goes to whether the brand took reasonable steps. Retail buyers and distributors increasingly ask, particularly for export. And a Responsible Person taking on a product will check, because they are the ones who answer to the authority. This is why the cheapest possible report so often costs the most: it passes unexamined for a year and fails on the day something matters. What all of these checks are really looking for is evidence of a genuine cosmetic product safety assessment, signed by one of the qualified safety assessors recognised under uk and eu cosmetics regulations, rather than a document produced to look the part. Our article on choosing a CPSR partner sets out the wider evaluation.

What happens if a report fails the test?

Legally, the product has been placed on the market without a valid safety assessment, which is a breach regardless of whether the formula is safe, and the remedy is to have a proper Cosmetic Product Safety Report prepared before further sales. Practically, the consequences depend on who found it. A marketplace suspends listings until a valid report is produced. Trading Standards will normally give a period to comply, with more serious consequences for a brand that ignores it or has been told before. An insurer may take the position that the brand did not meet its obligations. In every case the brand pays twice, once for the invalid report and once for the real one, plus the cost of the interruption. The good news is that a reassessment is usually straightforward: the formula and supplier documents already exist, so a competent assessor can often turn it around quickly, re-running the cosmetic safety assessment, re-checking ingredients against Annex I, and completing a fresh product safety assessment without starting from zero.

What about assessors outside the UK and EU?

Nothing in Article 10 requires the assessor to be established in any particular country; it requires the qualification. An assessor based outside the UK and EU can prepare a Cosmetic Product Safety Report provided they hold the qualifying degree and the report meets the Annex I format and assesses against the applicable regulations. What cannot be outsourced is the Responsible Person, who must be established in the market on the label and who holds the Product Information File at that address. In practice the two questions are often confused, and a brand will be told that a report is invalid because the assessor is abroad, which is not the test, or reassured that an overseas provider can act as its EU Responsible Person, which is not permitted. Keep them separate: qualification for the signature, establishment for the Responsible Person.

How do I verify a report I already hold?

• Find the signature block. A named individual, a qualification, a date.
• Check the product coverage. Does it name every variant you sell?
• Read the conclusion. Is there a reasoned Part B with conditions and warnings, or a single paragraph?
• Look for calculations. A margin of safety table and an allergen declaration are the signs of a real assessment.
• Check the markets. Does it cite the UK regulation, the EU regulation or both, as your sales require?
• Check the date against your formula. A report that predates a supplier or fragrance change needs an addendum.
• Ask the provider to confirm the signatory's qualification in writing. 
• Use the provider's verification route where one exists. 

Spectra publishes a verification page so that a retailer, a marketplace or a regulator can confirm that a report bearing our name is genuine and current, which is a question that used to require an email and a wait.

Does the signatory have to reassess when something changes?

The signature attaches to a specific product, formula and date, so when any of those move the report must move with them. A new fragrance supplier, a changed grade of an ingredient, a new variant, a packaging change that alters exposure, a claim revision, a new market, or an amendment to the annexes affecting an ingredient all require the assessor to review and, where appropriate, issue a dated signed addendum. The addendum carries the same signature requirement as the report itself, because it is part of the assessment. What a brand should not do is continue selling against a report that no longer describes the product and assume the original signature covers it; a report dated before a supplier change is evidence about a product the brand no longer makes. Ask any provider what an addendum costs and how quickly it arrives, because over a product life you will need more of them than you expect.

The questions to ask before you buy

•      Who will sign my Cosmetic Product Safety Report? A name.

•      What is their qualification, and in which discipline? A university degree in pharmacy, toxicology, medicine or similar.

•      Will the signature block show the name, qualification and date?

•      Do you carry professional indemnity insurance?

•      Can I see a redacted Part B from a comparable product?

•      Can a third party verify the report?

•      Who answers if a marketplace or regulator queries it?

A worked example: the same product assessed twice

A bath and body brand bought safety reports for eight products from an inexpensive provider. Each ran to thirty pages of generic text, described the ingredients in general terms, contained no exposure or margin of safety calculations, treated each fragrance as a single line, and ended with a company stamp. The products sold for fourteen months without incident. Then a marketplace review flagged the unnamed signatory, listings were suspended, and a Trading Standards enquiry followed a complaint on a separate product. Spectra reassessed all eight from the original formulas and supplier documents. Six were safe as formulated and received full reports within a week. One needed a fragrance reduction, because at the level used the limiting constituent exceeded its IFRA category limit. One required a preservative change, because its challenge test had never been performed and the system chosen did not work at the product's measured pH. The brand's comment afterwards was that the cheap reports had not been reports at all; they had been a fourteen month deferral of the actual assessment, at the price of a suspension and a reformulation.

Myths we hear

•      A company can sign a CPSR. Article 10 requires a named person.

•      A cosmetic science short course qualifies someone to sign. The qualification must be a university course in pharmacy, toxicology, medicine or a similar discipline.

•      Experience counts instead of a qualification. Experience matters above the legal floor, not instead of it.

•      There is a CPSR certificate that proves validity. There is no certificate; the report and its signature are the evidence.

•      Nobody ever checks. Marketplaces, insurers, Responsible Persons and Trading Standards all check, usually at an inconvenient moment.

What to do this week

•      Open every safety report you hold at the signature page.

•      Note the name, qualification and date on each.

•      Flag any report signed by a company or with no qualification stated.

•      Check each report names every variant you currently sell.

•      Get anything that fails reassessed before someone else finds it.

One sentence in Article 10 decides whether your Cosmetic Product Safety Report is a legal document or an expensive PDF. It takes a minute to check and it is the single most valuable minute a cosmetic brand can spend on its paperwork.
