Body-Safe Sex Toy Materials: What's Safe, What Isn't, and How to Tell
Which sex toy materials are body-safe, which are porous, and how to spot the marketing language that hides cheap plastics.

Sex toys occupy an odd regulatory space. In most countries they’re sold as novelty items rather than medical devices, which means the safety standards you’d expect for something used on mucous membranes largely don’t apply.
That doesn’t mean the market is dangerous. It means the responsibility for checking materials falls on you. This guide makes that straightforward.
The single distinction that matters: porous vs non-porous
Almost everything else follows from this.
Non-porous materials have a sealed surface. Nothing penetrates it, which means bacteria can’t take up residence inside the material. These can be properly cleaned and, in some cases, fully sterilised.
Porous materials have microscopic openings across the surface. Bacteria, fungi and biofilm settle into them, and no amount of surface washing removes what’s living below. A porous toy accumulates microbial residue over its life, and there is no way to reverse that.
This is why “just wash it well” isn’t sufficient advice for a porous toy. The material itself is the problem.
Safe materials
Platinum-cure silicone — the standard
The best general-purpose option. Non-porous, chemically stable, temperature tolerant, and flexible enough to feel good.
- Can be boiled or washed with soap and water
- Doesn’t degrade or leach over time
- Available across every price band
One caution: silicone toys and silicone lubricant can react, degrading the toy’s surface over time. Use water-based lubricant instead, or patch-test on the base first. Our lubricant compatibility guide covers this properly.
Watch for “silicone blend” or “silicone-like.” Those aren’t silicone. Blends can contain porous fillers, and the word “blend” is doing deliberate work in that sentence.
ABS plastic — safe and underrated
Hard, non-porous, easy to clean, inexpensive. Common in bullet vibrators and the handles of larger toys.
Less flexible than silicone, which some people prefer and others don’t. There’s no safety reason to avoid it, and it’s often what keeps a well-made budget toy affordable.
Borosilicate glass
Non-porous, entirely sterilisable, and holds temperature well if you like warming or cooling. Stronger than it looks — borosilicate is the same family as laboratory glassware.
Inspect for chips before each use, and discard anything damaged. See our roundup of glass options.
Stainless steel
Medical-grade steel (304 or 316) is fully non-porous and sterilisable, with substantial weight that some people specifically want. Effectively permanent, and priced accordingly.
Materials to avoid
Jelly rubber
The clearest one to avoid. Highly porous, often softened with phthalates, and prone to a distinctive chemical smell that indicates off-gassing.
Jelly toys can degrade visibly — becoming sticky or weeping oil. Usually identifiable by being translucent, brightly coloured, very soft, and unusually cheap.
PVC and vinyl
Porous, and typically softened with plasticisers. Sometimes labelled vaguely as “novelty rubber.”
TPE and TPR (thermoplastic elastomer/rubber)
The genuinely ambiguous category. TPE is phthalate-free and cheaper than silicone, which is why it’s widely used. But it’s porous, so it can’t be sterilised and shouldn’t be shared.
TPE isn’t dangerous in the way jelly rubber is. It’s a material with a shorter safe lifespan. Treat it as consumable — replace it periodically rather than keeping it for years.
What about phthalates?
Phthalates are plasticisers used to soften rigid plastics. Several have been restricted in children’s toys across the EU, UK and US on the basis of endocrine research.
Sex toys generally aren’t covered by those restrictions. The evidence on real-world exposure from occasional toy use is genuinely limited — this is an area where honest uncertainty is the right position, and anyone claiming definitive harm or definitive safety is overstating what’s known.
The practical answer is simple: body-safe silicone, ABS, glass and steel don’t require phthalates at all. Choosing them removes the question entirely rather than requiring you to resolve it.
Reading the label
| Listing says | What it likely means |
|---|---|
| “100% platinum-cure silicone” | Trustworthy — specific and verifiable |
| “Medical-grade silicone” | Usually fine, though “medical-grade” isn’t a regulated term here |
| “Silicone blend” | Contains something else. Assume porous |
| “Body-safe material” (unspecified) | A non-answer. Ask or skip |
| “Skin-friendly rubber” | Almost certainly TPE or jelly |
| “Novelty material” | Avoid |
| No material listed | Avoid |
The reliable heuristic: manufacturers using good materials say so specifically, because it justifies their price. Vagueness is a choice, and it’s rarely an innocent one.
Three physical checks
Smell it. Body-safe materials are close to odourless. A strong chemical or plastic smell means off-gassing.
Feel it. Silicone has slight drag against dry skin. Jelly and TPE feel slicker and oilier.
Look at it. Translucent, brightly coloured and very soft together is the classic jelly signature. Quality silicone is usually opaque.
Practical rules
- Non-porous for anything shared or used internally. If a toy is used with a partner, it must be sterilisable — or covered with a fresh condom each time.
- Never mix materials in storage. Some silicones react on contact with certain plastics, leaving both tacky. Store separately, in fabric bags rather than pressed together in a drawer. Full detail in our cleaning and storage guide.
- Replace porous toys on a schedule. TPE isn’t permanent. Every year or two for regularly used items.
- Retire anything damaged. Cracks and tears in any material create places bacteria can’t be cleaned out of.
- Use condoms over porous toys if you’re keeping one — the simplest way to make a TPE toy shareable and easier to clean.
Frequently asked questions
Can I boil a silicone toy? Fully silicone toys with no motor, yes — three minutes in boiling water. Anything containing electronics must never be submerged in boiling water; wash the surface instead.
Is “medical-grade silicone” a real standard? Not a regulated one in this context. It’s a marketing term that usually accompanies decent material but doesn’t guarantee it. “Platinum-cure” is the more meaningful signal.
How do I know if a toy has gone bad? Stickiness, weeping, colour change, softening, cracking, or a smell that’s developed over time. Any of these mean replace it.
Are expensive toys always safer? No — but price and material honesty correlate. Brands investing in silicone tend to say so, because it’s what they’re charging for.
The short version
Choose platinum-cure silicone, ABS plastic, borosilicate glass or stainless steel. Treat TPE as consumable and replace it regularly. Avoid jelly rubber and anything whose material the seller won’t name.
That’s most of sex toy safety, and it costs you nothing but reading the listing properly before you buy.
