Selling homemade soaps, perfumes, or lotions means working through safety standards and legal requirements that protect your customers. Before any product reaches someone's hands, it needs proper cosmetic testing and assessment to confirm it's safe for use. This guide walks you through the key regulations, from UK requirements to EU compliance, helping you turn your fragrance creations into a legitimate, market-ready business.

When you're selling cosmetic products in the UK, meeting the UK Cosmetics Regulation isn't optional. These rules protect consumers and establish the legal standards your products must meet.
Your business needs to tick these essential boxes:
Safety Assessment: Every product requires assessment by a suitably qualified cosmetic chemist, who produces a Cosmetic Product Safety Report (CPSR).
Product Information File (PIF): Keep a PIF for each product that includes your CPSR, formulation details, and proof of Good Manufacturing Practice (GMP) compliance (typically following ISO 22716).
Labelling Requirements: Your labels need the ingredients list, use-by date, batch number, and Responsible Person contact details.
Allergen Declaration: Any allergens above 0.001% in leave-on products or 0.01% in rinse-off products must be clearly listed.
Ban on Animal Testing: Neither your cosmetics nor their ingredients can be tested on animals.
Notification: Register your products with the Submit Cosmetic Product Notifications (SCPN) portal before you start selling.
Fragrance oils bring their own set of challenges because they contain complex chemical compositions that need careful analysis for allergens, must not contained banned substances under Annex II and be free or have minimal concentrations of substances limited under Annex III. For the full picture, get familiar with GOV.UK's official regulations for selling cosmetics in Great Britain.
If you're based in Northern Ireland, you'll need to follow both EU regulations and UK requirements. Check the dedicated Northern Ireland section on GOV.UK for specific guidance. Staying on top of these rules builds customer confidence that your personal care products are genuinely safe.
Selling into the EU means following Regulation (EC) No 1223/2009 to the letter. Here's what you need to know:
Compliance: This regulation forms the backbone of EU cosmetic safety, making sure all products are safe for consumers.
Safety Assessment & PIF: Just like in the UK, you need a thorough safety assessment and accessible PIF for every cosmetic product.
Labelling in Multiple Languages: Your labels must meet the language requirements of each country where you're selling.
Allergen Declaration: Clear allergen labelling matters especially for products that touch the skin.
Strict Restrictions on Ingredients: You must follow Annex II, which bans over 1,600 substances from cosmetic use .
CPNP Notification: Register with the Cosmetic Products Notification Portal (CPNP) EU, or SPNP (Submit Products Notification Portal) GB, before launching your products.
Navigating IFRA & EU Cosmetic Limit Certificates & product compatibility
The IFRA Certificate of Conformity plays a vital role in your safety assessment by setting safe fragrance concentration limits (like Category 9 for soaps). We include detailed IFRA certificates with our fragrance oils, giving your assessor the documentation they need to verify that your fragrance levels stay within safe boundaries and meet global product compatibility standards.
More recently, EU Cosmetic Limit Certificates have also become a vital part of the puzzle, as they outline how much fragrance oil can safely be used in cosmetic products under the EU/UK Cosmetic Regulations. We provide this certification as standard to provide you with clear guidance on formulations, ensuring your products remain compliant and safe for consumer use.
If you are not familiar with this document, CLP Services for Candle Maker’s blog post does a great job at explaining the finer details.
Getting a CPSR confirms your formulation is safe for consumers. Here's your roadmap:
1. Lock Down Your Recipe: Your formulation must be final before testing begins.
2. Collect Technical Documents: Gather MSDS sheets, IFRA certificates, and EU Cosmetic Limits (where required) – our technical documents are available via our website, and the EU Cosmetic Limits Certificate is available upon request, if not already provided for the fragrance oil you are working with.
3. Choose a Qualified Assessor: Ensure that your chosen Cosmetic Assessor is suitably qualified, by working with an assessor who is CTPA (The Cosmetic, Toiletry and Perfumery Association Limited) registered. The assessor will tell you exactly what documents you need to provide them with for the assessment to be completed.
4. Submit Your Information: Provide exact formulation percentages and all technical documentation.
5. Complete Additional Testing: Once you are satisfied that your recipe performs suitably in the finished cosmetic product, you will need to complete additional testing before your Cosmetic Assessor can prepare your CPSR. Water-based products (like lotions) need Preservative Efficacy Testing (PET) and stability testing in an accredited laboratory. Oil-based products typically don't require this.
6. Get Your CPSR: After review (usually 2-4 weeks), register via SCPN/CPNP and you're ready to sell!
What a CPSR entails for fragrance-based cosmetics
Your Cosmetic Product Safety Report (CPSR) must meet the minimum standards outlined in Annex I of both UK and EU Cosmetics Regulations.
"Protecting consumers is the cornerstone of a thriving marketplace."
Finding qualified assessors and starting the process
Only qualified professionals with backgrounds in pharmacy, toxicology, or related fields can conduct these assessments. Cosmetic Assessors who are members of the CTPA have been vetted by the association to ensure they are able to handle your CPSR requirements with expertise in fragrance oil formulations, helping your personal care products meet regulatory standards smoothly.
Key takeaways about cosmetic testing for fragrance products
Proper cosmetic testing forms the foundation of any sustainable cosmetic business. By following regulations and securing valid CPSRs, you protect both your customers and your brand reputation. Here at NI Candle Supplies, we remain committed to supporting our customers through every step of compliance and quality guidance, helping you create products that are both safe and exceptional.
What is a cosmetic test?
Cosmetic testing refers to various evaluations that confirm product safety. The most important is your Safety Assessment (CPSR). Depending on your product type, you might also need physical laboratory testing, including Stability Testing, Microbiological Testing, and Challenge Testing (Preservative Efficacy) to verify your preservative system works effectively.
How much does a CPSR cost in the UK?
CPSR costs depend on how complex your formulation is. Single product assessments typically run £150 to £300. If you want packages that cover a base recipe with multiple variations (different scents or colours), expect to pay £400 to £800 or more. Factor this mandatory cost into your business planning from the start. We would advise reaching out to an assessor, via the CTPA website, for a free quote on a bespoke CPSR.
