It should show how that conclusion was reached, which evidence was used and which conditions or warnings are required.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a cosmetic product safety assessment?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before a cosmetic product is placed on the EU market, the Responsible Person must ensure that it has undergone a safety assessment based on relevant information and that a CPSR has been prepared in accordance with Annex I of Regulation (EC) No 1223\/2009.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The CPSR has two main parts:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Part A: Cosmetic Product Safety Information<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Part A collects the information needed to assess the product.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Part B: Cosmetic Product Safety Assessment<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Part B contains the safety assessor\u2019s conclusion, reasoning, required warnings and professional approval.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reasoning is critical. EU guidance describes it as the core of the safety assessment because it explains how the assessor reached the final conclusion from the available information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who is allowed to complete the safety assessment?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Part B must be completed by a qualified safety assessor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The assessor must hold an appropriate formal qualification in pharmacy, toxicology, medicine or a similar discipline, or a qualification recognised as equivalent by an EU Member State.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A software platform may support data collection or calculations. It does not replace the professional judgement and responsibility of the qualified assessor.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What information should a good CPSR include?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Exact qualitative and quantitative composition<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The safety assessor needs the complete finished-product formula.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This should include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>every raw material<\/li>\n\n\n\n<li>the percentage used<\/li>\n\n\n\n<li>the composition of mixtures<\/li>\n\n\n\n<li>the intended function of each ingredient<\/li>\n\n\n\n<li>fragrance or flavour identifiers<\/li>\n\n\n\n<li>regulated substances within complex mixtures<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Trade names alone are usually insufficient because they do not reveal the substances that require toxicological assessment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For fragrances, the identity of the supplier and relevant regulated-substance information should be available to the Responsible Person and safety assessor.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Physical and chemical characteristics<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The assessment should consider relevant properties of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>individual substances<\/li>\n\n\n\n<li>raw-material mixtures<\/li>\n\n\n\n<li>the finished cosmetic product<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the product, this may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>pH<\/li>\n\n\n\n<li>viscosity<\/li>\n\n\n\n<li>appearance<\/li>\n\n\n\n<li>solubility<\/li>\n\n\n\n<li>particle size<\/li>\n\n\n\n<li>density<\/li>\n\n\n\n<li>relevant specifications<\/li>\n\n\n\n<li>analytical reference methods<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These properties can influence exposure, stability, performance and safety.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Product stability<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The assessment should use evidence showing that the cosmetic remains stable under reasonably foreseeable storage and use conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stability data may help assess:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>physical separation<\/li>\n\n\n\n<li>colour or odour changes<\/li>\n\n\n\n<li>pH changes<\/li>\n\n\n\n<li>viscosity changes<\/li>\n\n\n\n<li>degradation<\/li>\n\n\n\n<li>container interaction<\/li>\n\n\n\n<li>preservative performance<\/li>\n\n\n\n<li>expected shelf life<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A generic statement from the manufacturer is weaker than a documented stability programme appropriate to the product.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Microbiological quality<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Microbiological safety is especially important for products containing water, products used around the eyes and products used by vulnerable consumers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Relevant evidence may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>microbiological specifications<\/li>\n\n\n\n<li>total viable counts<\/li>\n\n\n\n<li>absence of specified microorganisms<\/li>\n\n\n\n<li>preservation-challenge testing<\/li>\n\n\n\n<li>packaging protection<\/li>\n\n\n\n<li>manufacturing controls<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Not every product requires the same test programme. If specific data are considered unnecessary, the absence should be scientifically justified.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Impurities, traces and packaging information<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The safety assessment must consider more than intentionally added ingredients.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Potential concerns may arise from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>raw-material impurities<\/li>\n\n\n\n<li>residual solvents<\/li>\n\n\n\n<li>heavy metals<\/li>\n\n\n\n<li>nitrosamines<\/li>\n\n\n\n<li>processing residues<\/li>\n\n\n\n<li>degradation products<\/li>\n\n\n\n<li>packaging interactions<\/li>\n\n\n\n<li>substances migrating from the container<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">EU guidance states that toxicologically relevant impurities and unintended substances should be identified and considered in the assessment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Intended and reasonably foreseeable use<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Exposure depends on how the product is actually used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The assessor should understand:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>application area<\/li>\n\n\n\n<li>frequency of use<\/li>\n\n\n\n<li>amount used<\/li>\n\n\n\n<li>rinse-off or leave-on status<\/li>\n\n\n\n<li>exposure duration<\/li>\n\n\n\n<li>target population<\/li>\n\n\n\n<li>professional or consumer use<\/li>\n\n\n\n<li>foreseeable misuse<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A face cream, shampoo, lip product and baby product cannot be assessed using identical exposure assumptions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Exposure to the cosmetic product<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The assessment should estimate consumer exposure based on realistic use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Relevant factors may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>application amount<\/li>\n\n\n\n<li>application frequency<\/li>\n\n\n\n<li>body surface area<\/li>\n\n\n\n<li>exposure route<\/li>\n\n\n\n<li>retention factor<\/li>\n\n\n\n<li>body weight<\/li>\n\n\n\n<li>target population<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These inputs form the basis for assessing exposure to individual ingredients.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Exposure to individual substances<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The assessor evaluates how much of each relevant ingredient may become systemically available.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This may involve calculating the Systemic Exposure Dosage and comparing it with toxicological reference values.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The calculation must reflect the actual concentration in the finished product and the intended product use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">9. Toxicological profile of each relevant substance<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A robust assessment considers toxicological endpoints that may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>acute toxicity<\/li>\n\n\n\n<li>irritation<\/li>\n\n\n\n<li>corrosion<\/li>\n\n\n\n<li>sensitisation<\/li>\n\n\n\n<li>repeated-dose toxicity<\/li>\n\n\n\n<li>mutagenicity<\/li>\n\n\n\n<li>carcinogenicity<\/li>\n\n\n\n<li>reproductive toxicity<\/li>\n\n\n\n<li>toxicokinetics<\/li>\n\n\n\n<li>phototoxicity<\/li>\n\n\n\n<li>local effects<\/li>\n\n\n\n<li>human experience<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Not every endpoint will have complete data. Where information is missing, the assessor should explain the scientific approach used to reach a conclusion.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">10. Undesirable and serious undesirable effects<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The safety assessment is not frozen at launch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Information about consumer reactions and serious undesirable effects should be collected, documented and made available to the safety assessor. Relevant new information may require the CPSR to be revised.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A brand therefore needs a post-market process, not only a pre-launch document.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">11. Relevant information about the product<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This section may include additional information that affects the assessment, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>user studies<\/li>\n\n\n\n<li>compatibility data<\/li>\n\n\n\n<li>clinical or instrumental studies<\/li>\n\n\n\n<li>experience with similar formulas<\/li>\n\n\n\n<li>reported reactions<\/li>\n\n\n\n<li>safety history<\/li>\n\n\n\n<li>supporting scientific literature<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The value of this information depends on its relevance and quality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What should Part B contain?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Assessment conclusion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The assessor should clearly state whether the product is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>safe<\/li>\n\n\n\n<li>safe subject to restrictions or conditions<\/li>\n\n\n\n<li>not safe<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If a product is not considered safe, it cannot be treated as compliant and should not be placed on the market.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Warnings and instructions for use<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The CPSR should identify any warnings or instructions required to ensure safe use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These may result from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>regulatory annexes<\/li>\n\n\n\n<li>the product format<\/li>\n\n\n\n<li>the target population<\/li>\n\n\n\n<li>exposure conditions<\/li>\n\n\n\n<li>professional use<\/li>\n\n\n\n<li>specific safety findings<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Scientific reasoning<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The report should explain how the assessor evaluated:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>identified hazards<\/li>\n\n\n\n<li>consumer exposure<\/li>\n\n\n\n<li>data quality<\/li>\n\n\n\n<li>uncertainties<\/li>\n\n\n\n<li>margins of safety<\/li>\n\n\n\n<li>relevant restrictions<\/li>\n\n\n\n<li>combined evidence<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A conclusion without transparent reasoning is difficult to defend.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Assessor credentials and approval<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The report should include the assessor\u2019s:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>name<\/li>\n\n\n\n<li>address<\/li>\n\n\n\n<li>qualifications<\/li>\n\n\n\n<li>date<\/li>\n\n\n\n<li>signature or secure electronic approval<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">There should be a clear link between the approved assessment, the exact formula and the assessment date.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common weaknesses in low-quality safety assessments<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Warning signs include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>no clear formula version<\/li>\n\n\n\n<li>incomplete raw-material composition<\/li>\n\n\n\n<li>no meaningful impurity assessment<\/li>\n\n\n\n<li>generic toxicology text<\/li>\n\n\n\n<li>missing exposure reasoning<\/li>\n\n\n\n<li>absent packaging consideration<\/li>\n\n\n\n<li>no explanation for missing tests<\/li>\n\n\n\n<li>unclear warnings<\/li>\n\n\n\n<li>no evidence of assessor qualifications<\/li>\n\n\n\n<li>no update process<\/li>\n\n\n\n<li>identical text across unrelated products<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The issue is not whether a report is long.
