The UK cosmetics industry is booming with innovation and independent brands, but bringing your product to market involves more than picking a label and hitting “launch” on your Shopify store. From legal requirements to ingredient documentation, UK cosmetics regulations are a tightly controlled space, and it’s easy to get lost.
Every week, Russell Regulatory Consultants is contacted by aspiring beauty brand owners who just discovered they need something called a CPSR. Most haven’t heard of a PIF. Many try to submit to SCPN without ingredient documentation. Some think listing percentages is optional. Very few have gathered the raw material documentation required to pass a safety assessment for cosmetics.
This article will walk you through what you actually need to sell cosmetics in the UK, and we’ll give you a free checklist to help you do it.
What Legal Requirements Apply in the UK?
The regulation of cosmetics in the UK is governed by the UK Cosmetics Regulation, derived from EU Regulation (EC) No 1223/2009. These requirements are outlined in the UK Cosmetics Regulation, which governs the regulation of cosmetics across Great Britain. These regulations apply to all cosmetic products sold in Great Britain (England, Scotland, and Wales).
To legally place a cosmetic product on the UK market, you must have:
- A designated UK Responsible Person (RP)
- A valid Cosmetic Product Safety Report (CPSR)
- A fully compiled Product Information File (PIF)
- Correctly labelled packaging, including the RP address
- Product notification submitted via the Submit Cosmetic Product Notification (SCPN) portal.
It doesn’t matter if you’re selling through Etsy, Amazon, a salon, or your own website. If the product is available in the UK, these laws apply.
Not sure what you’re missing?
What You Need Before You Can Get a CPSR
The Cosmetic Product Safety Report (CPSR) is the cornerstone of UK cosmetics regulation and a legal requirement under both UK and EU frameworks. This report is the outcome of a thorough safety assessment for cosmetics, evaluating your product’s ingredients, intended use, toxicological profile, and formulation.
But here’s the catch. A qualified safety assessor can’t prepare a CPSR without detailed supporting documentation. Too many brands reach out expecting a quick turnaround, only to discover they’re missing critical data.
If you want to understand exactly what goes into a cosmetic safety assessment, read our complete Guide to Cosmetic Safety Assessments in the UK.
To comply with cosmetics regulations and ensure your product is eligible for a valid safety report, you’ll need to prepare documentation across five essential areas.
1. Product Definition and Claims
Before submitting a cosmetic product safety report (CPSR), you must clearly define your product and its intended purpose. This information is essential for ensuring your product falls under the regulation of cosmetics and not into the territory of medicinal products or borderline classifications.
You’ll need documented answers to the following:
- Product name and functional description (e.g., “Botanical Facial Cleanser: a rinse-off gel cleanser for oily skin”)
- Intended use and method of application (e.g., applied with fingertips to the face, rinsed with water)
- Product category (e.g., skincare, haircare, colour cosmetics)
- All marketing claims (e.g., “reduces redness,” “brightens dull skin,” “natural ingredients”).
This information determines the regulatory route your product must follow under UK cosmetics regulation. Certain claims, such as “treats acne” or “repairs skin,” may require medicinal classification and cannot be made under cosmetics law.
The intended use and claims of your product will be directly assessed during the safety assessment for cosmetics, so accuracy in this area is crucial.
Tips from Dr Amy Russell, our Managing Director
“One of the most common mistakes I see is brands using medical language in their product descriptions. If you’re claiming to treat or cure anything, you could be falling outside cosmetics regulation.”
Not sure if your claims are compliant? Our team at Russell Regulatory can review your product language and help you stay compliant with both the UK and EU cosmetics regulation frameworks.
2. Full Ingredient Formula
To produce a valid CPSR, your safety assessor needs a complete and transparent breakdown of your formula. That means:
- A full INCI (International Nomenclature of Cosmetic Ingredients) list with exact percentages
- Supplier documentation for every raw material, including:
- Safety Data Sheets (SDS)
- Certificates of Analysis
- IFRA statements (required for any fragrance materials).
Without precise ingredient percentages, your assessor cannot calculate the Margin of Safety, a core element of any cosmetics safety assessment. Missing or vague data slows everything down. In fact, missing supplier documents are the number one cause of CPSR delays.
Ingredient-level detail is also essential for cross-referencing with Annexes II–VI of the UK cosmetics regulation, which lists prohibited and restricted substances.
Tips from Dr Amy Russell
“If you can’t get supplier documents for every single ingredient, you’re not ready for a CPSR. No shortcuts here. It’s about consumer safety, and regulators take that seriously.”
Russell Regulatory Consultants can help you audit your formula, liaise with suppliers, and fill in any gaps. We ensure that your documentation meets all requirements under both UK cosmetics regulations and EU legislation, allowing your CPSR to proceed smoothly.
3. Manufacturing and Testing Evidence
Even the safest formulation on paper can fail a CPSR if the product hasn’t been manufactured or tested to appropriate standards. Before your assessor can sign off, you’ll need clear documentation that proves the product is stable, hygienic, and safe for consumer use.
This means providing evidence that your product:
- Is manufactured under Good Manufacturing Practice (GMP), ideally ISO 22716-compliant
- Has undergone stability testing to support its shelf life and Period After Opening (PAO) claims
- Has passed Preservative Efficacy Testing (Challenge Testing), particularly if it’s a water-based formula prone to microbial growth
- Is packaged in materials that are chemically compatible with the formula (i.e., it won’t leach, degrade, or react).
The key here is the following:
- Without GMP, the safety and quality of your product cannot be guaranteed. This is a red flag in any safety assessment for cosmetics.
- Stability testing confirms that the product will perform and remain safe during its entire shelf life.
- Challenge testing is required to ensure your preservative system prevents microbial contamination.
- Packaging compatibility is crucial under UK cosmetics regulation and EU legislation, as leaching or degradation can pose health risks.
Tips from Dr Amy Russell
“GMP and testing gaps are some of the most overlooked areas for new brands. You can have the perfect formula, but without these tests, your CPSR will stall.”
Russell Regulatory can review your manufacturing documentation, verify test results, and connect you with trusted labs that meet the requirements of UK and EU cosmetics regulation.
4. Labelling and RP Details
Never forget that your product label is a legal document. Under the UK and EU cosmetics regulation, cosmetic labels must meet strict requirements. Non-compliant labelling is one of the fastest ways to get flagged by enforcement authorities or delay market entry.
At a minimum, your cosmetic label must include:
- The product name and function (unless obvious)
- Batch code, nominal content (e.g. 50ml), and Period After Opening (PAO) symbol
- Warnings and usage instructions (e.g., “Avoid contact with eyes”)
- Your UK Responsible Person’s (RP) name and UK address
- Ingredients listed by INCI name in descending order
- Country of origin (if imported)
- Language requirements: must be in English for the UK market.
Labelling is the only regulatory touchpoint visible to the end user and enforcement authorities. Your Responsible Person acts as the legal gatekeeper for the cosmetic product safety report and is liable for compliance. Critically, failing to meet labelling regulations can result in delisting, fines, or product recalls.
Not sure what a UK Responsible Person actually does? Read our guide, Understanding the Role and Responsibilities of the UK Responsible Person, for a detailed breakdown of legal duties and setup requirements.
Tips from Dr Amy Russell
“Most of the enforcement issues we see in the UK start with incorrect or missing label elements. Get your RP details and warning texts right, first time.”
We can act as your UK Responsible Person, provide a full label review, and ensure your packaging meets all requirements under the regulation of cosmetics in the UK and EU.
5. Product Information File (PIF)
The Product Information File (PIF) is your product’s master compliance dossier, and it’s legally required under both UK and EU cosmetics regulations. The PIF must be readily accessible to authorities for 10 years after the last batch of product is placed on the market.
Your PIF must include:
- The full Cosmetic Product Safety Report
- A detailed product description
- A statement of Good Manufacturing Practice (GMP) compliance
- Evidence to support claims made on the product
- A copy of the SCPN (Submit Cosmetic Product Notification) confirmation (for the UK market).
The PIF is the central file reviewed during inspections or investigations. Your product cannot legally be sold in Great Britain or the EU without a complete and accurate PIF. It shows that your safety assessment for cosmetics has been properly conducted and documented.
Tips from Dr Amy Russell
“Think of your PIF as your regulatory passport. It should reflect not just what’s in your product, but that you’ve considered everything around it: safety, manufacturing, and presentation.”
Russell Regulatory Consultants can compile or review your PIF to ensure every component meets the requirements under the regulation of cosmetics.

Common Cosmetic Compliance Pitfalls We See from New Brands
Even the most innovative cosmetics startups can run into trouble when they misunderstand (or underestimate) the documentation required under UK cosmetics regulation. Here are some of the most common mistakes we encounter:
Leaving INCI percentages blank because they’re considered “a trade secret”
Regulators and safety assessors require exact percentages for every ingredient. Without them, a CPSR cannot be completed.
Not gathering Safety Data Sheets (SDS), spec sheets, or Certificates of Analysis
Assuming suppliers will handle this is a major mistake. You need to obtain and verify this documentation yourself for every raw material.
Failing to include UK Responsible Person (RP) details on the product label
This is a mandatory labelling requirement under UK cosmetics regulation. Missing this could result in products being pulled from shelves.
Confusing the CPSR and the PIF
The safety assessment for cosmetics (CPSR) is just one part of the larger Product Information File (PIF). Treating them as interchangeable can leave critical gaps.
Submitting your product to the SCPN before compiling documentation
Premature submission without your CPSR, labelling, and ingredient documentation in place can trigger enforcement action.
Tips from Dr Amy Russell
“Your formula’s not compliant until every ingredient has valid safety documentation. Don’t assume your supplier has it. Ask and verify.”
Avoiding these pitfalls early can save you weeks of delays and ensure your brand launches with confidence and credibility.
