Most condoms are not vegan. The reason is not the latex itself but a processing ingredient called casein - a milk protein used during manufacturing. This surprises most people, because the finished product contains no visible animal ingredient and condom packaging rarely mentions it.
If you want to use vegan condoms, certified vegan options exist and perform identically to standard condoms in terms of protection. This guide explains why most condoms are not vegan, what certified vegan means in this context, and which brands to buy.
Why Most Condoms Are Not Vegan
Standard latex condoms are made from natural rubber latex, which is plant-derived. The latex itself is vegan. The issue is in the manufacturing process.
During vulcanisation - the process that turns raw latex into a strong, elastic material - casein is commonly used as a smoothing agent. Casein is a protein derived from cow's milk. It is applied to the latex to create a smooth, even surface on the finished condom. No casein remains in meaningful quantities in the finished product, but it is used in production, which means the manufacturing process is not vegan.
Most major condom brands use this method. Unless a brand specifically certifies their condoms as vegan, it is reasonable to assume casein has been used in production.
What Makes a Condom Certified Vegan?
A certified vegan condom is one manufactured without any animal-derived ingredients at any stage of production - including the vulcanisation process. Vegan condom brands typically replace casein with plant-derived or synthetic smoothing agents.
Vegan certification is granted by organisations such as The Vegan Society (which awards the Vegan Trademark) or equivalent certifying bodies. A condom labelled "vegan" without a certification mark is a marketing claim - a condom with a certification mark has been independently verified.
Both Glyde and Fair Squared - the primary certified vegan brands stocked at Condoms.uk - carry independent vegan certification and are also Fair Trade certified, meaning the natural rubber is sourced from farms meeting ethical labour and environmental standards.
Are Non-Latex Condoms Vegan?
Non-latex condoms - made from polyisoprene or polyurethane - do not use casein in manufacturing, since they are synthetic materials rather than natural rubber. This makes them vegan by default in most cases.
However, non-latex condoms may use other processing agents or lubricants that are not vegan. If you are strictly vegan, checking with the manufacturer is the safest approach.
Polyurethane condoms are generally considered vegan but are not typically certified. If certification matters to you, Glyde and Fair Squared are the verified options.
Polyisoprene condoms offer a similar feel to latex and are the standard non-latex recommendation for people with latex allergies. For the full guide to non-latex options: browse our non-latex condom range.
Certified Vegan Condom Brands
Glyde
Glyde is the most established certified vegan condom brand available in the UK. Glyde condoms carry The Vegan Society's Vegan Trademark and are also Fair Trade certified - both independently verified. They are made from natural rubber latex using plant-derived processing agents in place of casein.
The Glyde range covers a broad selection: standard, ultra-thin, large, slim fit, flavoured (strawberry, vanilla, blueberry, wildberry, cola), and dental dams. They perform to the same CE-marked safety standards as all condoms sold in the UK.
Recommended starting point: Glyde Ultra Condoms
Glyde's standard condom. Vegan Trademark certified, Fair Trade certified, natural rubber latex. Available in standard fit.

HANX is a UK-based brand producing certified vegan condoms designed specifically with women in mind - the brand was founded by two women doctors and positions itself around sexual health and wellness. HANX condoms are CE-marked, vegan certified, and free from parabens, glycerin, and spermicide.
Vegan and Fair Trade: Why They Often Go Together

In the natural rubber industry, vegan certification and Fair Trade certification often appear together - and it is not a coincidence. Brands committing to ethical production standards tend to address both the animal welfare and the human welfare dimensions of their supply chain simultaneously.
Natural rubber is predominantly grown in Southeast Asia and West Africa. Fair Trade certification ensures rubber tappers receive fair wages, safe working conditions, and a premium paid to their community. The same brands taking care to reformulate away from casein tend to be the same brands auditing their supply chain for labour standards.
Do Vegan Condoms Work as Well?
Yes. Vegan condoms are manufactured to the same CE-marked or ISO-certified standards as standard condoms. The change is in a processing step during manufacturing, not in the structural material or the finished product's integrity. Replacing casein with plant-derived alternatives does not affect the condom's thickness, elasticity, strength, or protection against pregnancy and STIs.
The practical performance of Glyde and Fair Squared condoms is equivalent to mainstream brands. Some people find they prefer the texture or feel - this varies by individual, as it does with any condom.
How to Check if a Condom Is Vegan
- Look for a certified vegan mark on the packaging - The Vegan Society's sunflower logo is the most recognised in the UK.
- Check the brand's website for explicit vegan certification details.
- If no certification is mentioned, assume casein has been used in production - this is the industry standard.
- "Natural" on packaging does not mean vegan. Natural rubber latex is plant-derived but is not vegan if casein was used in processing.
- Non-latex condoms (polyisoprene, polyurethane) do not use casein but are not always independently certified vegan.
Frequently Asked Questions
Are Durex condoms vegan?
Durex condoms are not certified vegan. Durex manufactures standard latex condoms using conventional processes, which include casein. Durex has not published vegan-certified alternatives as of our last review.
Are SKYN condoms vegan?
SKYN condoms are made from polyisoprene, a synthetic material that does not use casein in manufacturing. SKYN does not hold a formal vegan certification, but the manufacturing process does not use animal-derived ingredients in the same way latex processing does. If independent certification matters to you, Glyde or Fair Squared are the verified alternatives.
Are flavoured condoms vegan?
Flavoured latex condoms face the same casein issue as standard latex condoms unless specifically certified vegan. Glyde produces a full range of certified vegan flavoured condoms - strawberry, vanilla, blueberry, wildberry, and cola.
Can I use vegan lube with vegan condoms?
Yes - and it is worth checking your lube too. Some lubricants contain animal-derived ingredients (honey, beeswax, lanolin, glycerin from animal sources). Water-based lubes without these ingredients are generally vegan, but check the label or the brand's website if this matters to you. All water-based lubes are safe with latex condoms.
Are condoms cruelty-free?
This is separate from the vegan question but related. Most condom brands do not animal-test their finished products - condoms are tested mechanically and clinically. However, some ingredient suppliers may use animal testing for regulatory purposes. Certified vegan brands like Glyde and Fair Squared typically take a stronger position on this than mainstream brands.
