UK Cosmetic Labeling Requirements: Complete Guide
Proper labeling is a legal requirement for all cosmetic products sold in Great Britain. According to UK government guidance, cosmetic labeling must comply with Article 19 of the retained EU Regulation 1223/2009, as amended for the UK market.
Article 19 Overview
Article 19 of the UK's retained cosmetic regulation specifies mandatory labeling elements including: Responsible Person details, country of origin, nominal content, best-before date or PAO symbol, batch code, function of the product, list of ingredients, and required precautions.
UK RP name and address must appear on the label (mandatory since Jan 1, 2021)
Ingredient list must follow INCI nomenclature in descending order by weight
English language is mandatory for consumer-facing text in Great Britain
PAO symbol or best-before date required based on 30-month shelf life rule
Batch/lot number mandatory for traceability and recall purposes
EU RP address permitted until December 31, 2027 (transitional provision)
26 fragrance allergens must be declared above threshold concentrations
Mandatory Labeling Elements
1. UK Responsible Person Name and Address
According to official UK guidance, every cosmetic product must display:
- Full name of the UK Responsible Person
- Physical address in Great Britain (not PO Box)
- Country (if abbreviated, e.g., "UK" is acceptable)
| Element | Requirement | Example |
|---|---|---|
| Company Name | Legal entity name | ABC Cosmetics Ltd |
| Street Address | Full physical address | 123 High Street |
| City/Town | Required | London |
| Postcode | Required | SW1A 1AA |
| Country | Can abbreviate | UK or United Kingdom |
Transitional Period
Until December 31, 2027, products may display only an EU Responsible Person address. After this date, a UK RP address is mandatory. Products manufactured before this date can continue being sold until stock is exhausted.
2. Country of Origin
According to Business Companion guidance:
- Country of origin must be stated for products manufactured outside the UK
- "Made in [Country]" or "Product of [Country]" format acceptable
- For products manufactured in UK, country of origin is optional but recommended
3. Nominal Content
- Must state net weight (g or kg) or volume (ml or L)
- Metric units are mandatory
- Imperial units may be shown in addition (not instead)
- Exemption: products under 5g or 5ml, and free samples
| Product Size | Declaration Required | Format |
|---|---|---|
| Under 5g/5ml | Exempt | No declaration needed |
| 5g-50g / 5ml-50ml | Required | e.g., Net 30ml or Net wt 25g |
| Over 50g/50ml | Required | Must be minimum 2mm height |
| Aerosols | Net weight of contents | Excluding propellant weight |
| Multi-pack | Individual + total | e.g., 3 x 50ml (150ml) |
4. Date Marking: PAO vs Best-Before
According to Russell Regulatory Consultants, the 30-month rule determines which marking to use:
| Shelf Life | Marking Required | Symbol/Format |
|---|---|---|
| 30 months or less | Best Before End (BBE) date | Hourglass symbol + MM/YYYY |
| More than 30 months | Period After Opening (PAO) | Open jar symbol + months (e.g., 12M) |
| Single-use products | Neither required | Products used once and discarded |
| Products in sealed packaging | PAO not required | If opening cannot cause deterioration |
The PAO (Period After Opening) symbol is an open jar icon with the number of months the product remains safe after first opening:
PAO Symbol Requirements
The open jar symbol must include the period in months (e.g., "12M" for 12 months). If space is limited on the container, the symbol can appear on outer packaging with a hand-pointing symbol on the container directing consumers to the packaging.
5. Batch Number / Lot Code
According to UK government guidance:
- Must be present on container or packaging
- Enables traceability for recalls
- Format is determined by manufacturer (alphanumeric)
- Must link to manufacturing records and batch documentation
6. Function of the Product
The product's function must be clearly stated unless obvious from its presentation:
| Product Type | Function Clear? | Statement Needed? |
|---|---|---|
| Lipstick | Yes (shape/packaging) | No |
| Clear liquid in pump bottle | No | Yes - e.g., 'Facial Cleanser' |
| White cream in jar | Ambiguous | Yes - e.g., 'Night Cream' or 'Body Lotion' |
| Bar soap | Yes (traditional form) | No (but 'soap' often included) |
| Multi-use product | Varies | State primary function(s) |
7. Ingredient List (INCI)
According to Article 19 requirements:
Ingredient List Requirements
- Preceded by the word 'Ingredients' or 'Ingredients:' (in English)
- Listed in descending order of weight at time of mixing
- Ingredients below 1% can be listed in any order after those above 1%
- INCI (International Nomenclature Cosmetic Ingredient) names required
- Colorants can be listed in any order using CI numbers (e.g., CI 77891)
- Fragrances listed as 'Parfum' or 'Aroma'
- 26 designated allergens must be named individually above thresholds
Allergen Labeling
The 26 fragrance allergens in Annex III must be individually declared if present above 0.001% (10 ppm) in leave-on products or 0.01% (100 ppm) in rinse-off products. This is in addition to listing "Parfum" or "Aroma."
8. Precautions and Warnings
According to UK Annex III, specific warnings are mandatory for certain ingredients:
Language Requirements
English Mandatory

Elements not requiring translation:

Label Placement Rules
According to ComplianceGate's UK guide:
| Information | Container | Packaging | Notes |
|---|---|---|---|
| UK RP name/address | Required (or on packaging) | Required if not on container | Must be on at least one |
| Nominal content | Required (or on packaging) | Required if not on container | — |

Space Constraints

2024-2025 Ingredient Restriction Updates
The UK has implemented several independent ingredient restrictions since regulatory divergence began. According to CTPA regulatory updates, brands must ensure labels and formulations comply with the latest UK restrictions:
| Regulation | Effective Date | Key Restrictions |
|---|---|---|
| SI 2024/455 | April 2024 | CMR substance bans including additional Category 1A/1B carcinogens |
| SI 2024/1334 | November 2024 | Expanded fragrance allergen restrictions, additional preservative limits |
| SI 2025/413 | March 2025 | Methyl salicylate concentration limits in children's products |
| SI 2025/901 | July 2025 | UV filter updates and additional CMR prohibitions |
UK-Specific Restrictions
The UK no longer automatically adopts EU ingredient restrictions. While many restrictions align, some timelines and concentration limits may differ. Always verify your ingredients against current UK Annexes at legislation.gov.uk before finalizing labels and formulations.
Common Labeling Errors
According to CTPA, common labeling mistakes include:
Common UK Labeling Errors to Avoid
- Missing or incorrect UK RP address (still showing only EU RP after 2027)
- Ingredients not in descending order by weight
- Missing allergen declarations above threshold
- Using common names instead of INCI nomenclature
- Missing mandatory warnings for restricted ingredients
- PAO symbol without time period (e.g., open jar with no '12M')
- Batch code missing or illegible
- Information not in English (mandatory language)
- Claims that contradict product category (e.g., 'cures acne' for cosmetic)
- Nominal content in imperial only (metric required)

For online/distance sales, certain information must be available before purchase:
| Information | Required Pre-Purchase? | How to Display |
