Sex Toy Materials: What’s Safe and What Isn’t

Silicone, ABS, glass, stainless steel, TPE, jelly, a clear guide to what each material is, how to tell them apart, which to buy, which to be cautious about and which to avoid outright.

Of every question a first-time buyer asks, this is the one that matters most. Material determines whether a toy can be truly cleaned, whether it can be shared safely, how long it will last, whether it will react with lube, and, in some cases, whether it will off-gas chemicals that shouldn’t be in prolonged contact with mucous membranes. Every other characteristic of a toy is downstream of this one.

The good news is that the modern market is dominated by good materials at every price point. The category has mostly moved on from the porous-plastic era of twenty years ago. But the old materials still exist, they still get sold, and buyers who don’t know how to identify them can still end up with them.

The Green Light: Non-Porous, Safe, Long-Lived Materials

Silicone

Silicone is the modern standard, and rightly so. Medical-grade silicone is soft, warm to the touch, completely non-porous, hypoallergenic, sanitisable by boiling, safe with any water-based lube, and remarkably durable. A silicone toy, cared for properly, will last for years.

Not all silicone is created equal. Higher grades feel softer and warmer; lower grades feel stiffer and more plasticky. But even the low end of medical-grade silicone is orders of magnitude better than the porous alternatives. The one material caution is that silicone-based lubes bond with silicone toys and permanently damage the surface, use water-based lube with silicone toys, without exception.

Genuine silicone is difficult to identify by sight alone. A quick test: touch a small drop of silicone lube to an inconspicuous part of the toy. If the toy is real silicone, the two will start to bond in a way you can feel; if the toy is TPE marketed as silicone, nothing happens. This is a destructive test, the toy will develop a slight tacky spot where the lube touched, but it’s a definitive one.

ABS Plastic

ABS plastic is the hard, smooth plastic used in the shells of many vibrators, in some non-porous dildos, and in the handles of most rechargeable toys. It is non-porous, easy to clean, and completely safe. It has none of the softness of silicone, so it is used mostly for structural components and for firm, smooth-surfaced insertable toys.

ABS is not a caution material at all; it is a safe, boring standard. If a toy’s outer casing is ABS and its insertable part is silicone, that combination is common and fine.

Borosilicate Glass

Glass toys are made from borosilicate glass, the same material used in laboratory glassware, and are surprisingly durable. They are non-porous, sanitisable at high temperatures, safe with all lubes, and produce a distinctive sensation: firm, cool to the touch, weighty. Glass is excellent for internal stimulation, particularly G-spot work, where firmness matters.

The obvious caution is that glass is glass. A dropped glass toy on a hard floor can chip or break. This is why trusted glass toy manufacturers use borosilicate rather than ordinary soda-lime glass, borosilicate is much more resistant to thermal shock and to fracture. Never use a glass toy that shows any sign of cracking or chipping. Store glass toys somewhere they won’t be jostled.

Stainless Steel

Stainless steel toys, usually 316L medical-grade, are the heaviest, firmest, most durable option on the shelf. They are non-porous, sanitisable, safe with all lubes, and last forever. A well-made stainless steel toy is a lifetime purchase.

Weight is the defining characteristic. Users who like steel usually love it; users who prefer softer sensations usually don’t. This is not a first-purchase material for most people, but it is an excellent second or third purchase if the sensation profile appeals.

The Yellow Light: Use With Knowledge and Care

TPE (Thermoplastic Elastomer) and TPR (Thermoplastic Rubber)

TPE and TPR are soft, skin-like materials that dominate the manual stroker category and appear in some inexpensive insertable toys. They are cheaper than silicone, softer, and often marketed as “skin-safe” or “body-friendly.” They are also porous, cannot be truly sanitised, and will need to be replaced periodically.

TPE and TPR are not, usually, actively dangerous. They are, however, a compromise. If you buy a TPE stroker knowing what it is, treating it accordingly, cleaning thoroughly after every use, drying completely, replacing every twelve to eighteen months, the material is workable. If you buy a TPE insertable toy expecting silicone-like longevity and sanitisation, you will be disappointed and possibly at risk.

Some TPE formulations also contain plasticisers that off-gas over time, the “new toy smell” some products have, and while modern manufacturing has reduced this significantly, older or cheaper TPE toys can produce a smell that is a real indicator of chemistry you probably don’t want in prolonged contact with mucous membranes.

The rule of thumb: TPE is acceptable for strokers where the category is dominated by it and the alternative is a stiffer silicone experience. TPE is not acceptable for insertable toys, where silicone is available at similar prices and the safety trade-off is not worth it.

Elastomer Blends

“Elastomer” is a broad category that overlaps with TPE. When a toy is described as “elastomer” without further specification, treat it as TPE and apply the same considerations.

The Red Light: Avoid

Jelly

Jelly toys are made of PVC softened with phthalates, plasticisers that soften the material and give it its distinctive squishy feel. Phthalates have been linked to reproductive-system effects in animal studies and are banned in children’s toys in the United States and Europe for that reason. Their use in adult toys is legal but generally considered inadvisable.

Beyond the chemistry concern, jelly is porous, cannot be sanitised, degrades quickly, and produces a distinctive smell that many users find unpleasant. There is no scenario in which a jelly toy is a better buy than a silicone equivalent. Skip.

PVC

PVC toys without phthalates exist but are rare. In practice, PVC in the sex toy category usually means jelly, and the same guidance applies.

Latex

Latex is used in some restraints and inflatable products. It is not inherently dangerous but is a common allergen, and users with latex sensitivity should avoid it. Silicone alternatives exist for most latex-based products.

Any Unlabelled Material

If a product is described as “skin-safe”, “body-safe”, “body-friendly” or “premium material” without a specific material named, the ambiguity is intentional. Credible manufacturers name the material. Ambiguous descriptions usually hide TPE or jelly.

Testing a Material at Home

The silicone lube test, a small drop of silicone lube on an inconspicuous part of a supposed silicone toy, will tell you whether the toy is genuine silicone or a TPE substitute. Genuine silicone will develop a tacky spot; TPE will not. This is a definitive test.

A less-reliable smell test: fresh silicone is nearly odourless. Fresh TPE has a faint plasticky smell. Jelly has a strong, distinctive plastic smell that most users can identify. If a toy smells strongly, it is not silicone.

Lube Compatibility Summary

Water-based lube is compatible with every toy material and is the safe default. Silicone-based lube is incompatible with silicone toys. Oil-based lube is incompatible with latex and can degrade some plastics; it also stains fabrics and is generally impractical.

If you own toys in multiple materials and want to keep a single lube in the drawer, keep water-based. This eliminates every compatibility question.
