How to Choose a Cosmetic Safety Assessor

How to Choose a Cosmetic Safety Assessor

Quick Answer

Your safety assessor signs the part of the CPSR that says whether your product is safe, so the choice matters. The law sets one hard requirement: under Article 10, the assessment must be carried out by a person with a university-level qualification in pharmacy, toxicology, medicine or a similar discipline, or a course recognised as equivalent. Beyond that, a good assessor is one who works from your final formula and pack, explains their reasoning, asks for missing data instead of ignoring it, and stays available when your product changes.

What the Law Requires of an Assessor

Article 10(2) says the safety assessment set out in Part B of Annex I must be carried out by a person holding 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. In the UK version, equivalence is recognised by the Secretary of State. The report itself must record this: Annex I, Part B requires the assessor's name and address, proof of qualification, and date and signature. For what Part B actually contains, see our guide to CPSR Part A vs Part B.

Article 10 also requires the report to be kept up to date in view of additional relevant information generated after the product is placed on the market. That sentence has a practical consequence: you are not hiring an assessor for a one-off signature, you are choosing someone you may need again after every complaint, reformulation or pack change.

Seven Questions to Ask Before You Hire

1. What are your qualifications, and can I see the proof? You are entitled to see evidence that matches Article 10. The credentials must also appear in the signed report.
2. Which markets do your reports support? If you sell in both Great Britain and the EU, ask how they handle each market and whether any extra steps are needed for either. Our comparison of UK and EU PIF requirements shows where the markets differ.
3. What information do you need from me? A good answer lists the final formula, specifications, SDSs, stability and microbiology data, pack details and intended use, not just "send the ingredients".
4. What happens if my data is incomplete? You want to hear that they will ask for more data or explain the limits, not that they will sign anyway.
5. Will you assess my product in my final pack? The report should relate to the product as sold, including packaging and intended use.
6. How do you handle changes after launch? Ask what triggers a review, how long updates take and what they cost, so you know before you need them.
7. Can I see a sample report? A redacted example shows how clearly they explain their reasoning and whether all headings of Annex I are covered.

Green Flags and Red Flags

Area Green flag Red flag
Qualifications Clear, verifiable and named in the report Vague, or the report is unsigned
Data requests Specific list, follow-up questions Asks only for a name and ingredient list
Reasoning Explains the scientific basis for the conclusion Conclusion with no explanation
Warnings Clear statement on labelled warnings and instructions Silent on label wording
Speed Realistic timeline linked to your data readiness Promises a report before data arrives
After launch Clear update process and contact No answer on reformulations or complaints

Make Their Job Easier (and Your Report Better)

The quality of a safety report depends as much on your inputs as on the assessor. The Commission's guidelines on Annex I say the responsible person and the assessor should work together to gather the information Part A requires, and that the assessment follows a weight-of-evidence approach using all existing sources. In practice that means collecting documents first. Our step-by-step guide to building a PIF lists what to prepare, and our article on stability and challenge testing explains the data that most often arrives late.

If you use a contract manufacturer, make sure your assessor can receive the full formula, either from you or through a confidential arrangement. Our guide to PIFs for private label brands explains why this must be settled before the assessment starts.

Common Mistakes

Mistake #1 — Choosing on price alone. A cheap report that does not match your final formula or pack costs more when it has to be redone.

Mistake #2 — Never reading the report. The warnings and conclusions in Part B must reach your label. Read it, ask questions and keep a copy in the file.

Mistake #3 — Starting before the formula is final. Changes after the assessment can invalidate it.

Mistake #4 — No plan for updates. Article 10 expects the report to be kept current, so know in advance who will do it.

Practical Checklist

  • Ask for proof of qualification that fits Article 10 before engaging.
  • Confirm which markets the report will support.
  • Prepare the final formula, specifications, SDSs, stability and microbiology data first.
  • Request a sample report to judge clarity of reasoning.
  • Agree timelines, update process and update costs in writing.
  • Read Part B and transfer its warnings and instructions to the label.
  • File the signed, dated report in the PIF and diarise a review date.

Frequently Asked Questions

What qualifications must a cosmetic safety assessor have?

Article 10 requires 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.

Can I use the same assessor for several products?

Yes, but each product needs its own assessment because formula, pack, intended use and exposure differ. An assessor who already knows your brand may work faster, but the report must still cover each product individually.

What if I reformulate after the report is signed?

Ask your assessor to review the change before the new formula is sold. The report must be kept up to date, and a change to ingredients, exposure or stability may require revisions or a new assessment.

Is the Responsible Person the same as the safety assessor?

Not necessarily. The Responsible Person is legally accountable for the product and its file, while the safety assessor carries out the assessment in Part B. They can be the same organisation if the qualifications requirement is met, but the roles are different.

Final Word

A safety assessor is not just a signature on a form; they are the professional whose judgement your whole file leans on. Ask the seven questions, check the credentials, give them good data and agree how updates will work. That small amount of diligence at the start pays back every time your product, or your inspector, asks a hard question.
