Yes, Evera's Mousse No.10 is vegan: its label lists no animal-derived ingredient, and Evera states that it contains none and is never tested on animals. But for any hair mousse the honest answer is "check", because a label cannot prove where an ingredient came from. Beeswax, carmine, keratin and lanolin are the usual animal-derived culprits, and "cruelty-free" is a separate question from "vegan". Vegan also does not mean natural or silicone-free: Mousse No.10 contains amodimethicone, a silicone. Below: a label walk of its full ingredient list, the sources, and a checklist for any mousse.
Vegan, cruelty-free, natural: three different questions
Shoppers search "vegan hair mousse" and "cruelty free hair mousse" as if they were one claim.
| Term | What it asks | Who checks it |
|---|---|---|
| Vegan | Is any ingredient derived from an animal? | The brand, or a third-party scheme such as the Vegan Trademark |
| Cruelty-free / never tested on animals | Was the product or its ingredients tested on animals? | The brand's own statement; UK law sets a floor for testing done to meet the cosmetics rules |
| Natural / silicone-free | Is the formula plant-based or free of a named ingredient class? | The brand; you read the label for any named ingredient |
A mousse can be vegan and still contain a silicone, a synthetic preservative or a propellant gas. Treat each claim separately.
What the data says
- The definition is wide. The Vegan Society defines veganism as seeking to exclude, as far as is possible and practicable, all exploitation of and cruelty to animals, and says vegans avoid "animal-derived materials, products tested on animals" and places that use animals for entertainment.
- The strictest certification covers both. The Vegan Trademark standard says the manufacture and development of the product and its ingredients must not involve "any animal product, by-product or derivative", and that neither may involve animal testing of any sort, including legally required tests carried out by or for the company.
- Some animal ingredients are easy to spot. The Vegan Society names beeswax (a stiffening agent), carmine (made by crushing insects, used for red and purple pigment) and keratin (a protein often derived from the hair and horns of farmed animals) as everyday cosmetic examples, and suggests plant proteins such as hydrolysed wheat, soya and corn as alternatives. Lanolin, is another common one.
- Others are impossible to tell by name. The Cosmetic Ingredient Review (CIR) Expert Panel's 2014 safety assessment covered 21 "animal- and plant-derived" amino acid mixtures used as skin and hair conditioners. The same name can be used whatever the source, so an ingredient called "serine" or "arginine" does not tell you whether it is plant or animal.
- The label shows what, not where from. Under Article 19 of the UK-retained cosmetics regulation, ingredients are listed in descending order of weight, anything under 1% can follow in any order, and perfume is declared simply as "parfum". The list says nothing about origin.
- UK law bans some animal testing, not all of the story. Article 18 of that regulation stops a cosmetic being placed on the market where the final formulation or its ingredients were animal-tested to meet the regulation. Historic data may still be used, and animal testing in the UK for those purposes is banned. In May 2023 the government also said no new licences would be granted for animal testing of chemicals used exclusively as cosmetic ingredients, after admitting a small number of time-limited licences had been issued between 2019 and 2022 under REACH chemicals rules for worker and environmental safety. Cruelty Free International pointed out that chemicals used only in cosmetics are roughly 20% of those used in cosmetic production. So "legal in the UK" is a baseline for testing done for cosmetic rules, not proof that no ingredient anywhere in the supply chain was tested for another purpose.
The practical lesson: a vegan or cruelty-free claim is only as good as the brand behind it. Where you need certainty, look for a third-party mark. Where you cannot get it, ask the brand for its statement.
A label walk through Mousse No.10
This is the complete ingredient list from the Mousse No.10 product page, in label order: Aqua, Propane, Myristyl Alcohol, Butane, Cetrimonium Chloride, Isobutane, Phenoxyethanol, Parfum, Amodimethicone, Caramel, Ethylhexylglycerin, Vanillin, Trideceth-10, Citric Acid, Aloe Barbadensis Leaf Juice, Propylene Glycol, Glycerin, Glyceryl Oleate, CI 47005, PEG-8, BHT, Hexylene Glycol, BHA, Soy Amino Acids, Wheat Amino Acids, Nettle Leaf Extract, Threonine, Serine, Arginine HCl, PEG-8/SMDI Copolymer, Carbomer, Palmitoyl Myristyl Serinate, Sodium Polyacrylate, Ascorbyl Palmitate.
| Group | On the label | Vegan reading |
|---|---|---|
| Water and propellant gases | Aqua, Propane, Butane, Isobutane | No animal question |
| Common animal-derived ingredients | Beeswax, lanolin, carmine (CI 75470), keratin | None of them is listed |
| Plant extracts and plant amino acids | Aloe juice, nettle leaf extract, soy amino acids, wheat amino acids | Plant by name |
| Amino acids with no source stated | Threonine, Serine, Arginine HCl | Source is not on the label; Evera states plant-derived amino acids |
| Fatty alcohols, glycerides and humectants | Myristyl Alcohol, Glyceryl Oleate, Palmitoyl Myristyl Serinate, Glycerin, Propylene Glycol, PEG-8, Hexylene Glycol, Trideceth-10 | Names do not state plant or animal origin; rests on the brand's statement |
| Conditioning agents | Cetrimonium Chloride, Amodimethicone | Synthetic; amodimethicone is a silicone |
| Preservatives and antioxidants | Phenoxyethanol, Ethylhexylglycerin, BHT, BHA, Ascorbyl Palmitate, Citric Acid | Synthetic or lab-made; ascorbyl palmitate is a vitamin C ester with no source stated |
| Scent and colour | Parfum, Vanillin, Caramel, CI 47005 | No animal ingredient named; fragrance is declared only as "parfum" |
| Texture polymers | Carbomer, Sodium Polyacrylate, PEG-8/SMDI Copolymer | Synthetic polymers |
So the list passes the first test: none of the usual animal ingredients appears. The second test, where the unspecified fatty and amino-acid ingredients came from, cannot be done from the label. That is where Evera's own statement matters: its product page says "No animal-derived ingredients" and "Never tested on animals". This article rests on that statement, not on a third-party certificate, so if you need supplier-level proof, ask us before you buy.
What vegan does not mean here
Mousse No.10 is not silicone-free. It contains amodimethicone, a silicone used to condition hair. Silicones are synthetic, so they do not break vegan rules, but if you are avoiding silicones for other reasons, this is not your mousse. It also contains BHT and BHA (antioxidant preservatives), phenoxyethanol (a preservative) and fragrance. It is paraben-free, and we do not call it natural or organic.
It contains soy amino acids and wheat amino acids. The EU's Scientific Committee on Consumer Safety found in 2014 that the overall risk of sensitisation to hydrolysed wheat proteins "appears to be low", with one notable outbreak linked to a single product in Japan, and found them safe up to a peptide size of 3.5 kDa. That opinion covers hydrolysed wheat proteins, a related ingredient rather than this exact one, so if you have a wheat or soy allergy, check with a pharmacist or GP first.
Finally, our brand-wide position, because it comes up whenever vegan hair care is discussed: Evera's shampoos contain sodium coco-sulfate, a gentle, coconut-derived cleanser that is nonetheless a sulfate. It is vegan, but it is not "sulfate-free". We explain the evidence in our guide to whether sodium coco-sulfate is bad for hair. The mousse, mask and conditioner list no sulfate cleanser.
What customers say
We hold 14 reviews of Mousse No.10 on our own site. All are five stars and 2 are from verified purchases, which limits how much weight they carry. None of the 14 mentions the word vegan; they talk about feel, scent and frizz. Olivia wrote: "It is lightweight yet incredibly nourishing. I use it after the shower when the hair is damp and it helps me comb through any tangles." Several reviewers praise the scent and one says it has none; the label lists parfum, so expect a scent. A handful of reviews is an anecdote, not a trial.
How to choose a vegan hair mousse
- Scan for the usual animal ingredients. Look for cera alba or beeswax, lanolin, carmine or CI 75470, and keratin or other hydrolysed proteins whose source is not stated.
- Look for a third-party mark if you need certainty. The Vegan Society says its trademark team checks every ingredient against its criteria. A brand's own claim is weaker evidence, though honest brands will answer questions.
- Ask about unspecified ingredients. Amino acids, glycerin and fatty alcohols can come from plant or animal raw materials.
- Treat cruelty-free as its own question. Ask for the brand's animal-testing statement, and whether it sells anywhere that requires animal testing.
- Decide what else you need. If silicone-free matters, read the list for names ending "-cone" or "-siloxane". If you react to fragrance, avoid parfum.
- Patch-test first. Our 30-day returns promise covers unopened, sealed products within 30 days of delivery, so open one only when you are ready to keep it.

FAQ
Is hair mousse vegan?
Not automatically. Many mousses are free of animal ingredients, but some contain beeswax, keratin or carmine, and a label rarely states whether ingredients such as amino acids, glycerin or fatty alcohols came from plants or animals. Check the list for the usual animal ingredients, and look for a third-party vegan mark or a clear brand statement.
Is Evera Mousse No.10 vegan and cruelty-free?
Evera states that Mousse No.10 contains no animal-derived ingredients and is never tested on animals, and its label lists none of the usual animal ingredients. This is the brand's own statement rather than a third-party certificate. The mousse is not silicone-free: it contains amodimethicone, and it also contains fragrance, BHT and BHA.
Does vegan mean cruelty-free?
No, though the two overlap. Vegan is about animal-derived ingredients. Never tested on animals is about testing. The Vegan Society definition and the Vegan Trademark standard cover both, but a brand can use one claim without the other. UK law bans animal testing of cosmetics and their ingredients to meet the cosmetics regulation, so a UK-sold cosmetic starts from that baseline, but we found no definition of the word "cruelty-free" in the regulation articles we read, so it is the brand's choice of words.
Is a vegan mousse silicone-free or natural?
Not necessarily. Silicones such as amodimethicone are synthetic and do not break vegan rules, so a vegan mousse can contain one. Mousse No.10 does. Vegan says nothing about natural, organic or free-from claims, so read the ingredient list for whatever you want to avoid.
Which ingredients make a hair mousse not vegan?
The Vegan Society names beeswax, carmine and keratin among everyday cosmetic examples, and lanolin from sheep's wool is another. Watch also for hydrolysed proteins and amino acids with no stated source. If an ingredient could be plant or animal, ask the brand rather than guess.
