Quick answer: Yes. If you sell handmade soap in the UK, you almost always need a Cosmetic Product Safety Report (CPSR) before your first sale. This applies to cold process, melt-and-pour, natural, liquid, and cream soaps, whether you sell from home, at craft fairs, on Etsy, or through your own website.
Handmade soap is one of the most popular cosmetic products to make and sell, but it is also one of the most misunderstood under UK cosmetics law. Many soap makers believe cold process or natural soap is exempt from the rules because it is handmade or produced in small batches. That simply isn’t true.
If you’re wondering whether you need a handmade soap CPSR, it is legal to sell handmade soap without a CPSR in the UK. A cold process soap CPSR is required; the answer is simply yes. In almost every case, you need a Cosmetic Product Safety Report before your soap can be sold legally.
Whether you sell from home, at craft fairs, through your own website, or on Etsy, the same rules apply. This guide covers everything you need to know, including:
- Do you need a CPSR for handmade soap in the UK?
- Does cold process soap need a CPSR in the UK?
- Can you sell handmade soap on Etsy UK without a CPSR?

Do You Need a CPSR to Sell Handmade Soap in the UK?
If your handmade soap is designed to clean or care for the skin, UK law treats it as a cosmetic product. That means you must have a Cosmetic Product Safety Report (CPSR) before you sell it.
There are no exceptions for small businesses, home kitchens, craft fairs, Etsy shops, or small production batches. Selling one bar of soap follows the same legal rules as selling thousands. The common belief that handmade or natural soap is exempt comes from US regulations, not UK law.
Most handmade soaps require a CPSR, including:
- Cold process and hot process soap
- Melt-and-pour soap
- Liquid soap and foaming hand wash
- Cream soap and soft soap paste
- Syndet bars and soap-free cleansing bars
The only rare exception is a product sold purely as an industrial cleaner with no cosmetic purpose or skin-care claims.
What Does a Cold Process Soap CPSR Include?
Cold-processed soap requires a more detailed CPSR because the finished bar differs from the ingredients you started with. Unlike melt-and-pour soap, cold process soap is created through saponification, a chemical reaction between oils and sodium hydroxide (lye).
During curing:
- oils react with sodium hydroxide,
- soap salts are formed,
- natural glycerin is produced,
- excess alkali should disappear,
- the finished bar becomes safe for normal skin use.
Your CPSR assessor evaluates the finished soap, not simply the raw ingredients you started with.
The assessment confirms:
- complete saponification
- acceptable pH
- no excess free alkali
- appropriate superfat level
- safe ingredient concentrations
- appropriate fragrance levels
- compliant labeling
- expected consumer use
Proper curing records are often requested because incomplete curing can affect product safety.
Cold Process Soap CPSR Checklist
| Document | Why it’s needed |
| Full recipe | Exact weights or percentages of every ingredient |
| Lye calculation | Sodium hydroxide and water amounts used |
| Superfat level | Shows the percentage of unreacted oils |
| SAP values | Confirms correct lye calculation |
| Free alkali evidence | pH reading or documented curing records |
| IFRA certificates | Confirms fragrance is used within safe limits |
| Allergen declaration | Identifies allergens that must appear on the label |
| CI numbers | Required for colorants, micas and pigments |
| Additive specifications | Details for clays, botanicals, milks and exfoliants |
Why the INCI List Looks Different
One of the biggest surprises for first-time soap makers is discovering that the ingredients shown on their CPSR are not identical to the ingredients they used in their recipe.
This is completely normal. During saponification, oils are chemically transformed into soap salts.
For example:
| Ingredient used | INCI name after saponification |
| Olive oil | Sodium Olivate |
| Coconut oil | Sodium Cocoate |
| Palm oil | Sodium Palmate |
Any superfat oils remain listed separately, while fragrance appears as Parfum with any required fragrance allergens.
Listing raw oils alongside Sodium Hydroxide instead of the finished soap salts is one of the most common labeling mistakes among handmade soap makers.
Melt-and-Pour Soap CPSR:
Melt-and-pour soap uses a base that has already undergone saponification before you receive it. Because of this, your assessor does not need to review the soap-making chemistry.
Instead, the assessment focuses on what you add to the base, such as fragrances, essential oils, colorants and exfoliants.
The compliance requirements are exactly the same as cold process soap. You still need a CPSR, SCPN notification, and compliant labeling, but the assessment is usually quicker because there is less technical data to review.
Melt-and-Pour Soap CPSR Documents
| Document | Why it’s needed |
| Base INCI list | Identifies the ingredients in the soap base |
| Supplier safety documents | Confirms the base is suitable for cosmetic use |
| IFRA certificates | Verifies fragrance usage limits |
| Allergen declaration | Identifies allergens for labelling |
| CI numbers | Required for colourants and pigments |
| Additive specifications | Details for botanicals and exfoliants |
| Packaging information | Used during the final assessment |
Liquid and Cream Soap Additional Requirements
Liquid soaps, cream soaps, foaming hand washes and similar products present different safety risks compared with solid soap bars.
Because they contain water, they provide a more favourable environment for microbial growth.
For this reason, safety assessors generally expect additional evidence before issuing a CPSR.
Most liquid soap assessments therefore include:
| Requirement | Why it’s required |
| Preservative system | Prevents microbial growth |
| ISO 11930 challenge test | Proves the preservative works |
| ISO 17516 compliance | Confirms acceptable microbiological limits |
| Stability testing | Supports the product’s shelf life |
These extra requirements are why liquid and cream soap CPSRs usually cost more than bar soap assessments.
Why Bar Soap Usually Doesn’t Need Challenge Testing
Most properly cured cold-processed and melt-and-pour soaps are considered to pose a low microbiological risk.
Bar soap contains very little available water and naturally has a relatively high pH, making it difficult for bacteria and mould to grow. Because of this, many soap bars qualify for a documented microbiological justification instead of a full ISO 11930 challenge test.
However, your assessor may still consider how the product is used. For example, soaps that remain wet between uses or products designed for repeated contact with water may require additional justification before the CPSR is signed.
Fragrance and Essential Oils
Many handmade soap makers think essential oils are automatically safe because they are natural. Under UK cosmetics law, that is not true. Essential oils are treated the same as synthetic fragrances because many contain regulated fragrance allergens.
Before your soap maker’s CPSR can be signed, two things must be checked:
- Your fragrance or essential oil must be used within the correct IFRA limit for rinse-off soap.
- Any regulated allergen above the legal threshold must appear on your label by its INCI name, alongside Parfum.
Using a natural ingredient does not remove these legal requirements.
Documents Your Assessor Will Need
| Document | Why It Matters |
| IFRA Certificate | Confirms your fragrance or essential oil is used within the safe limit for bar soap. Without it, the assessor cannot confirm safe use. |
| Allergen Declaration | Lists the regulated fragrance allergens in the fragrance or essential oil. This tells the assessor which allergens must appear on your label. |
One final point is easy to overlook. If you switch to a different fragrance supplier after receiving your CPSR, even if the fragrance has the same name, the allergen profile may differ. That can change your ingredient list and may mean your CPSR needs to be updated before you continue selling.
Stability Testing and Soap Shelf Life
Your CPSR should show that your soap stays safe and stable throughout its shelf life, not just when it is first made. Stability testing provides the evidence for this.
For bar soap, you record changes in pH, color, scent, texture, and appearance over time under different storage conditions. You also check for problems like rancidity, fading, fragrance loss, cracking, or sweating.
These records help you decide the shelf life shown on your label. It should be based on your own test results, not on estimates or another soap maker’s product.
Best-Before Date or PAO
| Format | Durability Label Required |
| Cold process bar | Best-before date (minimum durability) |
| Melt-and-pour bar | Best-before date |
| Liquid or cream soap | PAO symbol (e.g. 12M) plus stability data |
For most bar soaps, a best-before date is the appropriate format. For liquid and cream soaps, a Period After Opening symbol is standard. Either way, the figure must be backed by stability records.
Handmade Soap Labeling Requirements UK 2026
A valid CPSR is only half the legal picture. Your label must comply with UK cosmetics regulations independently, and label errors are among the most common reasons soap makers run into problems with Trading Standards or marketplace compliance teams.
Every bar of handmade soap sold in the UK must display the following on the packaging:
- Ingredient list in INCI names, in descending order of weight at time of manufacture
- Fragrance allergen declarations for any regulated allergen above the threshold
- Net weight of the product
- Best-before date or PAO symbol, depending on format
- Batch or lot number for traceability
- Responsible Person name and UK address
- Function of the product where it is not obvious from presentation
- Any warnings or precautions identified by the assessor in Part B
Who Is the Responsible Person for Handmade Soap?
The Responsible Person is the individual or business legally accountable for the product’s compliance. For most independent soap makers selling under their own brand, that is you. Your name and a UK address must appear on every label. If you are selling through a third-party brand or having your soap white-labeled, the Responsible Person arrangement needs to be formally agreed and documented, as the legal liability rests with whoever holds that role.
Common Labelling Mistakes That Cause Problems
- Listing raw oils and sodium hydroxide instead of the correct soap salt INCI names
- Missing allergen declarations for essential oils on the assumption that natural ingredients are exempt
- Making “lye-free” or “pH-neutral” claims on a genuinely alkaline cold process bar, which breaches the cosmetic claims rules
- Printing labels before the CPSR is finalized, then discovering the assessor has identified additional warnings that now need to appear on pack
- Using non-cosmetic grade craft glitters or colorants that are not approved for skin contact, which can invalidate the safety assessment entirely
Is It Legal to Sell Handmade Soap on Etsy UK Without a CPSR?
UK cosmetics law requires a valid CPSR before your handmade soap can be sold. Etsy also requires sellers to follow all applicable laws, so selling without a CPSR puts your listing at risk.
Online marketplaces now check cosmetic products more carefully than before. If you cannot provide the required compliance documents, platforms like Etsy, Amazon, and Not On The High Street may remove your listings or suspend your account. A customer complaint, a reported skin reaction, or a routine check by the authorities can also lead to your documents being reviewed.
Then your next section naturally follows:
What Happens If You Sell Handmade Soap Without a CPSR?
- Trading Standards action: You may be told to stop selling your products immediately.
- Marketplace removal: Your listings may be removed, and your seller account may be suspended.
- Legal liability: You may be responsible if your product causes harm.
- Business impact: Wholesale buyers and retailers may refuse to stock non-compliant products.
Getting a CPSR before you sell is far easier and less expensive than dealing with enforcement action later.
What Happens If You Change Your Recipe After Receiving a CPSR?
Your CPSR only covers the exact recipe that was assessed. If you change the formula after it has been approved, you may also need to update your CPSR.
- Minor changes: Switching to a fragrance from the same supplier with the same allergen profile may only need a CPSR update.
- Major changes: Adding a new oil, changing your superfat level, or using a different fragrance with a different allergen profile will usually require a new or amended assessment.
- Before changing: Always check with your safety assessor.
- Best practice: Finalize your recipe before applying for a CPSR. Making changes after approval can delay your launch and increase costs.
How Much Does a Soap CPSR Cost in the UK?
Simple soap is among the more affordable cosmetic products to assess. A straightforward cold-process or melt-and-pour bar typically starts at around £55 for a single product. Liquid and cream soaps cost more because of the additional testing requirements.
What tends to push costs higher:
- Complex recipes with many oils, butters, or active ingredients
- Multiple fragrance suppliers, each requiring separate IFRA verification
- Water-containing formats requiring a preservative challenge test
- Incomplete documentation that causes the assessor to request missing information
- Recipe changes after the initial assessment
