When Can a Cosmetic Product Safety Report Support a Hypoallergenic Claim? The CPSR Test Behind the Word
Share
The short answer
A Cosmetic Product Safety Report can support a hypoallergenic claim only when the formula has been designed to minimise allergenic potential and the brand holds evidence for that design. In practice the assessor expects fragrance allergens above labelling thresholds to be excluded, ingredients with a significant sensitisation record avoided, a written design rationale in the Product Information File, and ideally a human repeat insult patch test or sensitive skin panel study. The claim may never imply the absence of any allergen or guarantee that no reaction will occur, so allergy free is always refused.
Key takeaways
- Hypoallergenic is a regulated claim with a technical definition, not a certification, and no scheme issues it.
- A CPSR assessor refuses the claim on any product containing a fragrance with declared allergens, whatever else the formula does well.
- The evidence expected is an exclusion list, a written design rationale, and human testing under dermatological supervision where the claim is prominent.
- Allergy free, guaranteed and non allergenic are refused outright, because no product can promise that.
- Fragrance free, unscented and suitable for sensitive skin are different claims with different evidence, and unscented is the weakest of the three.
- Consumers can check the claim in two minutes from the ingredient list alone.
Hypoallergenic arrives on nearly every draft artwork for a sensitive skin range, and it is one of the claims Spectra's assessors refuse most often. Not because the word is forbidden, but because it has a definition and most products using it do not meet it. The Commission's technical document accompanying Regulation (EU) No 655/2013 states that hypoallergenic may be used only where the product has been designed to minimise its allergenic potential, that the claim must be substantiated, and that it must never imply the absence of any allergen or guarantee against a reaction. Retained in Great Britain and enforced through the Cosmetic Products Enforcement Regulations 2013, that is the test the Cosmetic Product Safety Report applies, alongside the allergen labelling required by Regulation (EC) No 1223/2009 and expanded by Regulation (EU) 2023/1545.
This article is written for brands first and consumers second. It explains what the claim legally means, what the assessor actually asks for before approving it, how the sensitisation assessment inside a Cosmetic Product Safety Report works, which ingredient groups carry the weight, how the expanded EU allergen list changes the calculation from July 2026, the difference between hypoallergenic, fragrance free, unscented and suitable for sensitive skin, what human testing adds and what it costs in time, a worked example of a brand that got the claim and one that did not, and a two minute check any buyer can run from the back of the pack.
What does hypoallergenic legally mean?
That the product has been designed to minimise its potential to cause allergic reactions, that the brand can substantiate that design, and that the claim does not imply the product is free of any allergen or that no allergic reaction can occur. Three consequences follow. First, it is a claim about design and evidence, not a certification; no body issues it and no register lists it. Second, it is not a guarantee, because allergy is a response of the individual and almost any substance can sensitise someone. Third, because it is a claim, it falls under the six common criteria, so it must be truthful, evidenced, honest, fair and capable of informing a decision, and the evidence must sit in the Product Information File where a regulator can ask for it.
What does the assessor ask for before approving the claim?
• An exclusion list. Which known sensitisers were deliberately left out and why: fragrance allergens above labelling thresholds, preservatives with a significant sensitisation record, lanolin where relevant, daisy family botanicals, and anything else the brand chose against.
• A design rationale in writing. Not a paragraph of marketing, but a short technical note explaining the choices: why this preservative system, why no fragrance, why this emulsifier.
• A short ingredient list. Fewer ingredients means fewer opportunities to react, and an assessor notices when a hypoallergenic claim sits on a list of forty two items.
• Supporting human data where the claim is prominent. A human repeat insult patch test, or a sensitive skin panel study under dermatological supervision.
• Consistency with the allergen declaration. A product whose label names five fragrance allergens after Parfum cannot claim hypoallergenic.
• No absolute language. Allergy free, non allergenic, guaranteed, suitable for all sensitive skin: each is refused.
In practice
The fastest way to lose the hypoallergenic claim is a fragrance. The fastest way to earn it is to leave the fragrance out and say so plainly.
How does the sensitisation assessment inside the CPSR work?
Part A section 8 requires a toxicological profile for every ingredient, and skin sensitisation is one of the endpoints. The assessor identifies which ingredients have sensitisation potential, establishes the level at which each is used, and considers whether exposure from this product at this level is acceptable. Fragrance is the dominant input: a concentrate is expanded to its constituents, each sensitising constituent is assessed, and the most restrictive one usually sets the maximum fragrance level for the product. The same section produces the allergen declaration by calculating each declarable allergen's concentration in the finished product against the thresholds, 0.001 percent for leave on and 0.01 percent for rinse off. Part B then records the conclusion, the fragrance cap, the allergens to name on the label, and whether claims such as hypoallergenic are supported. The claim is therefore not a marketing decision reviewed afterwards; it is an output of the same calculation that sets your fragrance level.
Which ingredient groups carry the weight?
| Group | Why it matters | What a hypoallergenic design does |
|---|---|---|
| Fragrance and essential oils | The commonest cause of cosmetic contact allergy | Exclude entirely, including masking fragrance and essential oils |
| Preservatives | Records vary widely between systems | Choose an established system with a good tolerance record and say why |
| Botanical extracts | Plant materials can sensitise, notably the daisy family | Keep few, avoid the known reactors, document the choice |
| Lanolin and derivatives | A recognised contact allergen for some | Avoid, or justify and test |
| Colourants | Relevant in colour cosmetics rather than skincare | Restrict to well tolerated pigments; check Annex IV field of application |
| Hair dye substances | Potent sensitisers with mandatory allergy warnings | A hypoallergenic claim on an oxidative hair colour is refused |
What changes with the expanded EU allergen list?
A great deal, for fragranced ranges. Regulation (EU) 2023/1545 expanded the allergens that must be named on EU labels from 26 to more than 80, including several essential oils in their own right, with products placed on the EU market from 31 July 2026 required to comply and existing stock covered by 31 July 2028. Products that previously declared two or three allergens may now declare six or eight, and products that declared none may now declare several. For a brand claiming hypoallergenic this is decisive: the longer declaration makes the contradiction between the claim and the label visible to anyone who reads the back of the pack. Spectra recalculates allergen declarations against the expanded list as standard, and issues addenda across ranges where a supplier's statement has been reissued. Our fragrance document checklist sets out what to request from suppliers.
Hypoallergenic, fragrance free, unscented or sensitive skin?
| Claim | What it asserts | Evidence the CPSR expects | Common failure |
|---|---|---|---|
| Hypoallergenic | Designed to minimise allergenic potential | Exclusion list, design rationale, human data where prominent | Made on a fragranced product |
| Fragrance free | No fragrance added for scent | Formula with no Parfum, no essential oils, no masking fragrance | Essential oils present and described as natural scent rather than fragrance |
| Unscented | No perceptible smell | Formula that may include a masking fragrance | Presented as if it meant fragrance free |
| Suitable for sensitive skin | Formulated for low irritation potential | Mildness data, often an in use study or patch test | Claimed without any test at all |
| Dermatologist tested | A dermatologist was involved in a test | The study protocol and result | Implying the test was for allergy, or that the result was good |
The strongest combination, and the one Spectra recommends to sensitive skin brands, is fragrance free plus hypoallergenic with a short ingredient list and a patch tested formula, each claim stated separately with its own evidence, rather than one vague sentence doing the work of three.
What does human testing add, and what does it cost in time?
A human repeat insult patch test applies the product repeatedly to a panel of volunteers under occlusion, rests, then challenges, to detect induced sensitisation; a sensitive skin panel study applies the product in use to volunteers with self declared or clinically assessed sensitive skin under dermatological supervision. Neither proves that nobody will ever react, and no assessor will let a brand say so. What they do is turn a design rationale into evidence, which matters when the claim is prominent on the front of pack rather than one word in a paragraph. Budget several weeks: recruitment, application phases and reporting typically run four to six weeks, which is why the decision belongs at formulation rather than at artwork. The report goes into the Product Information File and its reference goes into the claims table.
Ask yourself
Does your hypoallergenic product's ingredient list contain Parfum, any allergen names, or an essential oil? If yes, the claim will be struck, and the only question is whether it is struck by your assessor now or by a Trading Standards officer later.
A worked example: two sensitive skin launches
Brand A submits a calming moisturiser for hypoallergenic approval. The formula has nineteen ingredients, no fragrance, a well established preservative system, no daisy family botanicals, and a written note explaining each choice. The brand commissions a patch test on thirty volunteers under dermatological supervision, which comes back clean. Part B supports fragrance free, hypoallergenic and dermatologist tested as three separate claims, each with its evidence referenced in the claims table, and requires no allergen declaration because there is none to make. Brand B submits a soothing balm described as hypoallergenic and gentle for sensitive skin. The formula contains a lavender essential oil at 0.4 percent, which produces declarations for linalool, limonene and, under the expanded list, the oil itself. The assessor supports the product as safe, caps the oil, specifies the declarations, and strikes hypoallergenic. The brand has two options: remove the oil and re submit, or keep the scent and drop the claim. It removes the oil, and its second batch carries both claims and a shorter ingredient list. The assessment cost the same either way; the difference was a month of artwork.
Does a hypoallergenic claim change the rest of the assessment?
It narrows it rather than complicating it. A formula built for the claim usually has fewer ingredients, no fragrance and a conventional preservative system, all of which make the toxicological work shorter and the margins of safety comfortable. Where it does add work is in the documentation: the assessor reviews the exclusion list and design rationale, checks any patch test report for protocol and result, and writes the claim position into Part B so the brand has something to show a retailer. Two secondary effects are worth planning for. A fragrance free product often needs a slightly more robust preservative system, because fragrance components sometimes contribute incidental antimicrobial activity that is now absent, so the challenge test matters more. And a short ingredient list leaves nowhere to hide a stability problem, so accelerated stability data is worth having before launch rather than after the first customer complaint.
The two minute check for buyers
• Is there Parfum, Fragrance or Aroma in the list? If yes, treat hypoallergenic as decorative.
• Are there allergen names after Parfum? Each is a declared sensitiser above threshold.
• Are there essential oils by their Latin names in a leave on product? Those are fragrance too.
• How long is the list? Short lists give fewer opportunities to react.
• Does the brand say what it excluded and why? A specific answer means a real design; repeating the word means marketing.
Does it say allergy free or guaranteed? Those claims are not permitted, and their presence tells you the brand has not checked.

How should a brand build a product that earns the claim?
• Decide at formulation, not at artwork.
• Exclude fragrance completely. No Parfum, no essential oils, no masking scent.
• Choose the preservative for tolerance and write down why.
• Keep the list short and justify each addition.
• Commission a patch test if the claim will be prominent.
• Never write allergy free, non allergenic or guaranteed.
• Put the rationale, the study and the allergen calculation in the Product Information File.
• Have the assessor confirm the claim in Part B before the plates are made.
Myths we hear
• Hypoallergenic is certified. No body certifies it; it is a claim the brand must substantiate.
• It means nobody can react. It means lower probability across the population, never zero for an individual.
• Natural products are hypoallergenic by default. Essential oils and botanicals are among the commonest sensitisers.
• Unscented is the same as fragrance free. A masking fragrance is still fragrance and still declares allergens.
• We can add the claim now and test later. The evidence must exist when the claim is made.
What to do this week
• Check every product carrying a hypoallergenic claim for Parfum and allergen names.
• Write the exclusion list and design rationale for the ones that pass.
• Ask suppliers for allergen statements against the expanded list.
• Book a patch test for any product where the claim is front of pack.
• Send the artwork to your assessor before print.
Hypoallergenic is worth having precisely because it is hard to earn. A Cosmetic Product Safety Report that supports it is a document a sensitive skin brand can stand behind, and you can verify any report Spectra signs before you send it to a retailer.
