A Cosmetic Product Safety Assessment is a systematic scientific evaluation confirming that a cosmetic product will not harm human health under normal or reasonably foreseeable use. It examines every ingredient, the finished formulation, packaging interactions, and real-world exposure before a product reaches consumers. In the EU and UK, this assessment takes the form of a mandatory Cosmetic Product Safety Report (CPSR) signed by a qualified safety assessor.
For brands entering regulated markets, this document is not optional paperwork. Without it, a product cannot legally be placed on the EU or UK market, cannot be notified through the CPNP or SCNP portals, and may be refused by distributors, retailers, and online marketplaces. The same principle applies in other regions, though the documentation and responsible parties differ.
What the Assessment Actually Covers
A complete Cosmetic Product Safety Assessment reviews more than the formula. It evaluates the product as consumers will actually use it, including how much they apply, how often, where on the body, and who might use it, including children or people with sensitive skin.
.The EU and UK have specific cosmetic safety assessment requirements that manufacturers must meet before placing products on the market. Under the EU and UK cosmetic regulatory requirements, the Cosmetic Product Safety Report (CPSR) is divided into two parts. Part A gathers the safety information: qualitative and quantitative composition, physical and chemical characteristics, stability data, microbiological quality, impurities and traces, packaging material safety, and a full exposure and toxicological profile. Part B contains the assessor’s scientific conclusion, including the margin of safety, any warnings or conditions of use, and the assessor’s qualifications and signature.

Who Can Sign a Cosmetic Safety Assessment
The person who signs Part B must hold a university degree in pharmacy, toxicology, medicine, or a recognised equivalent discipline. This is a legal requirement under Regulation (EC) No 1223/2009 in the EU and the parallel UK Cosmetics Regulation. A formulator, brand owner, or regulatory consultant without these qualifications cannot issue the safety conclusion.
This is where specialist providers such as OMC Medical and dedicated regulatory consultancies fit in. They either employ qualified assessors or work with them to compile the necessary data, review test reports, and manage the full PIF.
Regional Differences in Cosmetic Product Safety Requirements
In the United States, the Modernization of Cosmetics Regulation Act (MoCRA) changed the landscape. It requires a responsible person to ensure and document adequate safety substantiation, though the format differs from the EU CPSR. The FDA does not pre-approve cosmetic products, but it can request records during inspections.
The Data Behind the Assessment
A credible Cosmetic Product Safety Assessment depends on reliable input data. Assessors typically need the full INCI composition with percentages, physical and chemical specifications, stability and compatibility test results, preservative efficacy or challenge testing data, and information on impurities or traces. For products with specific claims, such as SPF, additional validated testing may be required.
Cosmetic product testing [sic] laboratories support this process through microbiology testing, stability studies, and analytical chemistry. The quality of these inputs directly affects the assessor’s ability to reach a defensible conclusion. Missing data is one of the most common reasons assessments stall or require revision.
Common Mistakes That Delay an Assessment
Several recurring issues slow down Cosmetic Product Safety Assessments. Submitting incomplete percentage breakdowns, where ingredients do not total one hundred percent, is a frequent problem. Another is failing to account for impurities or traces that are restricted under Cosmetic Safety Regulations, such as certain fragrance allergens or residual solvents.
Packaging compatibility is often overlooked. A formula may be safe in isolation, but if the packaging leaches substances into the product or fails to protect it from contamination, the assessment must address that. Similarly, stability data that does not cover the intended shelf life leaves the assessor unable to confirm safety over time.
Practical Steps for Brands
Brands preparing for a Cosmetic Product Safety Assessment should gather documentation before engaging an assessor. This includes the complete formula, raw material safety data sheets, any existing test reports, and the final label text for Label review. The label matters because warnings, usage instructions, and ingredient lists form part of the safety justification.
Good Manufacturing Practices are also relevant. While GMP compliance is a separate requirement, the assessor may request information on manufacturing conditions, especially for microbiologically sensitive products. Cosmetic product registration through the CPNP or SCNP portals can only proceed once the CPSR is in place and the responsible person has confirmed compliance.
For brands new to regulated markets, working with a compliance partner that understands Cosmetic Safety Regulations across multiple jurisdictions can reduce the risk of rework. The assessment is not a one-time formality. It must be updated when the formula, packaging, or available safety data changes. If you are preparing a product for the EU, UK, or US market and need support with safety documentation, contact OMC Medical to discuss your specific compliance requirements.
