Not reliably, because casein, a milk protein, is “often found in conventional brands” of latex condoms, according to Glyde. SKYN says none of its products contain animal derivatives. HANX says it is certified by The Vegan Society, while Glyde calls itself the only condom brand ever certified.
Why a latex condom can fail the vegan test
Latex is not the problem. Natural rubber latex is tapped from rubber trees, and nothing about the raw material involves an animal. What decides it is how that latex gets turned into a condom.
Glyde describes its own formula as “high-quality sustainably harvested natural rubber latex” and says it substitutes “milk-derived casein (often found in conventional brands)” with thistle extract. That is a manufacturer stating, in plain words, that a dairy protein is often found in the brands it competes with. It is one of only two such descriptions among the makers’ own pages we read, and it comes from a rival with a clear reason to say it. Treat it as the reason to check a brand, not as a verdict on any particular box.
The awkward part is that a processing aid is not the sort of thing you expect printed beside the size and the expiry date. Every answer we found for this article came from a brand’s own website. None came from packaging, so the work happens online or in the brand’s inbox.
Casein is the same milk protein you already avoid in cheese. Here it is simply hidden one step further back, in manufacture rather than in the ingredient list. The same hidden-casein question comes up with wine, which our guide to whether alcohol is vegan works through.
Condom brands compared on what they say about animal derivatives
You may have come here for seven brands side by side. This comparison has five, because those are the five whose makers’ own pages we read. We also found Sustain and Jonny described as vegan, but only on a third-party blog and a retailer’s journal, and this site does not clear a product on a page its maker did not write. They join the table when we have read their own statements.
Everything below is taken from the brands’ own pages. These are self-reports, and formulations change, so check the date on this page against the date you are buying.
| Brand | What the brand’s own page says | Third-party mark named | Base material stated | Scope of the statement | Where we read it |
|---|---|---|---|---|---|
| Glyde | Thistle extract in place of milk-derived casein | The Vegan Society | Natural rubber latex | Its condom formula | Glyde America FAQ |
| SKYN | “None of our products contain animal derivatives” | None named in the answer | Not stated in the answer | Every SKYN product | SKYN New Zealand FAQ |
| HANX | No animal by-products such as casein | The Vegan Society | Not stated on the page we read | Its condoms | HANX FAQ |
| Fair Squared | “Made entirely without casein” | The Vegan Society | Natural rubber | Its condoms and menstrual cups | Fair Squared vegan FAQ |
| EXS | Certified by the Vegan Society, “PETA approved” | The Vegan Society, PETA | Not stated on the page we read | Its condom range | EXS blog |
Read across the columns and SKYN stands apart as the one brand naming no certifier. Glyde and Fair Squared are the only two that tell you what the condom is made from, natural rubber in both cases. SKYN’s answer reaches furthest, across its whole range.
Glyde, our pick
The claim comes with a certifier attached, and with the exact swap. Glyde says it is certified vegan by The Vegan Society and names thistle extract as what replaced casein. A brand that tells you what it removed and what replaced it has answered the question you actually have.
Glyde has two downsides. By its own description it is natural rubber latex, so if you avoid latex for any reason, this is not your box. And its claim to be the only certified condom brand sits badly beside three other brands’ pages, which the section below gets into. Neither changes our pick for a vegan who is fine with latex and wants a mark rather than a promise.
Fair Squared
Fair Squared says its vegan products avoid any ingredients of animal origin, “regardless of how they are sourced”. That reaches past casein, which most of the other statements stop at. The downside is Glyde’s: natural rubber, so latex-avoiders skip it. If Glyde is not on the shelf where you shop, this is the one we’d reach for next.
SKYN
SKYN’s FAQ answers “Are your condoms vegan-friendly?” with “Yes. None of our products contain animal derivatives.” That covers the whole range, which helps if SKYN is already in your drawer.
The flaw is what the answer leaves out. It names no certifier, so you are relying on the company’s own declaration, and we read it on SKYN’s New Zealand site only. If a registered vegan mark is your threshold, do not buy SKYN on the strength of this FAQ alone.
HANX
HANX says its condoms contain no animal by-products such as casein and that it is officially certified by The Vegan Society. The catch is that nothing we read covers what HANX condoms are made from, so a latex-avoider has to ask before buying.
EXS
EXS says its condom range is certified by the Vegan Society and PETA approved, and that it supplies the NHS. The statement sits in a blog post rather than a product page and names no ingredient, so it tells you a mark exists without saying what was swapped. If you need to know the material, ask EXS directly.
Four brands, one “only”
Glyde’s FAQ says Glyde is “the only condom brand ever certified vegan by The Vegan Society”. HANX, Fair Squared and EXS each say, on their own pages, that The Vegan Society certified them.
Those cannot all be true as written. At least one page is out of date or overstating, and we did not check The Vegan Society’s own records for this article, so we cannot tell you which. It does show that a brand’s sentence about its own certification is still the brand talking, and the certifier is the one worth asking. If you picked Glyde believing it was the only certified condom, you have more choice than its page suggests.
Who should not buy these
If you avoid latex, Glyde and Fair Squared are out by their own descriptions. Nothing we read covers what HANX or EXS condoms are made from, so ask before buying.
If you will only buy a product carrying a third-party vegan mark, SKYN’s FAQ does not give you one. It may still be vegan. It is not certified on anything we read.
If you are loyal to a brand not named here, this article cannot help you yet. Nothing we read from the makers of Durex, Trojan, Sustain or Jonny lets us clear or condemn them, and the checks below are how you settle it for whatever is on your shelf.
How to check a condom brand yourself
- Search the brand’s FAQ for the word casein as well as the word vegan. A brand that names casein and says what replaced it, as Glyde does, has thought about manufacture as well as ingredients.
- Look the brand up on The Vegan Society’s own website before you trust a certification line on the brand’s site, since the pages above show that brand wording can contradict itself.
- Make sure the statement you are reading sits on the version of the site for the country you are buying in.
- If the condom is pre-lubricated and the lubricant lists glycerin, ask the brand where its glycerin comes from, because glycerin can be made from plant oils or from animal fat.
- Email the brand if its FAQ is silent, and ask about animal-derived processing aids as well as ingredients, so an answer about the ingredient list alone does not let casein slip past.
If you want one box and no further reading, buy Glyde. If Glyde’s latex rules it out for you, start with SKYN and confirm its answer covers the range sold where you live.
