The sex toy industry is almost entirely unregulated. In most countries, including the US and Canada, adult products are not classified as medical devices, which means manufacturers don't need to disclose what their toys are made from, test for safety, or meet any materials standard before putting something on a shelf. That's not a scare tactic — it's the actual legal situation, and it matters because some of the most common cheap toy materials contain chemicals that genuinely shouldn't be going near mucous membranes.
The vaginal and anal tissues are highly permeable. Unlike the outer skin, they lack a thick protective layer, which means anything that leaches off a toy in those areas has a direct path to the bloodstream. This is why the same phthalate levels that are regulated in children's toys, because they're considered too risky for children to mouth, are found in some adult toys with no restriction at all. The sensitivity of the tissues involved, and the nature of how toys are used, makes material choice meaningfully different than, say, choosing a plastic spoon.
Phthalates are a family of chemical plasticizers added to rigid plastics to make them soft and flexible. They're what makes "jelly rubber" toys feel squishy rather than hard. The US Environmental Protection Agency classifies several phthalates as possible human carcinogens and known endocrine disruptors — meaning they interfere with hormone signaling. They've been linked to male fertility issues, insulin resistance, asthma, and neurodevelopmental problems in children. Some variants are already banned in the EU for use in children's toys. They haven't been banned in adult toys in most markets, which is why you still find them in cheap, brightly colored gel vibrators and realistic jelly dildos.
The giveaway that a toy likely contains phthalates is material labeling. If a toy is described as "jelly," "rubber," or "PVC" without further specification, it almost certainly contains phthalates. A strong chemical smell, a sticky or greasy surface texture, and a semi-transparent or translucent look are all warning signs of phthalate-containing materials.
Jelly rubber and PVC are the main offenders. These are porous materials, meaning they have microscopic holes that trap bacteria, bodily fluids, and cleaning product residue even after washing. They cannot be fully sterilized, so bacteria from one use survives to the next. Combined with the phthalate issue, these are the toys researchers and harm-reduction organizations most consistently flag as problematic.
TPE and TPR (thermoplastic elastomer and thermoplastic rubber) are softer, more modern materials that are sometimes presented as safer alternatives. The reality is more complicated: TPE and TPR are also porous, and what exactly goes into them varies considerably by manufacturer and price point. Some formulations may be fine for external use; none should be used internally without a condom barrier, since they can't be sterilized.
Latex is allergenic for a meaningful portion of the population and degrades chemically over time, making it unreliable for anything beyond limited-use products.
Medical-grade silicone is the gold standard. It is non-porous, hypoallergenic, chemically inert (meaning it doesn't leach anything into the body), easy to clean, and can be fully sterilized by boiling or running through a dishwasher without soap. It warms quickly to body temperature and has a smooth surface that's comfortable internally. The Couples Co. silicone dildo collection is built on this standard — the collection description specifically calls out body-safe and hypoallergenic as category requirements.
A quick way to spot real silicone: it is never fully transparent or see-through. Genuine silicone is always at least slightly opaque. If a toy is labeled silicone but is completely clear, it likely contains filler materials. Real silicone also leaves no residue on your fingers when you rub it, and it has no chemical smell.
ABS plastic (the same hard plastic used in Lego bricks) is another fully body-safe material for the hard, non-flexible parts of a toy, such as the handle or motor housing of a vibrator. It's non-porous and easily sanitized. The Magic Wand Micro explicitly lists phthalate-free on its product specs — a straightforward confirmation that it uses materials that meet this standard.
Borosilicate glass and stainless steel are also fully body-safe, non-porous, and can be boiled or run through a dishwasher. Glass toys are firm and smooth, and because glass conducts temperature well they can be warmed or cooled for sensation play. Stainless steel toys are heavy and extremely durable. Both materials are completely inert and among the easiest to clean of any toy material.
It's a useful signal, but it's not the whole picture. A toy can be phthalate-free and still be made from porous TPE or TPR that harbors bacteria. The MADE SAFE organization, which reviews consumer products for toxic ingredients, notes that phthalate-free labeling only addresses one category of concern and doesn't guarantee the absence of other chemical additives or the non-porous quality needed for safe internal use. The safest approach is to look for phthalate-free and non-porous (or 100% silicone / borosilicate glass / stainless steel) together, rather than treating either label as sufficient on its own.
Silicone-based lubricants bond with silicone toy surfaces and cause them to degrade over time, leaving the material pitted and porous — which defeats the entire point of buying a non-porous toy. The fix is straightforward: always use a water-based lubricant with silicone toys. Our water-based lubes are compatible with all toy materials, body-safe, and formulated to provide comfort without damaging the surface of high-quality silicone products. This is one of the most commonly overlooked maintenance rules, and it matters more as toys get more expensive.
Before buying any toy, look for explicit material disclosure — the full material name, not a vague term like "body-safe rubber" or "premium jelly." Check that the toy is described as non-porous. Look for phthalate-free and, for vibrators, ensure the hard parts are ABS plastic. Trust the smell: a toy that smells like a hardware store or has a strong plastic or chemical odor is telling you something. If you can't find clear material information and the brand doesn't respond when you ask, that's usually a meaningful signal about what's inside.
The safest materials for toys used internally are medical-grade silicone, borosilicate glass, stainless steel, and ABS plastic for hard components. Avoid jelly rubber, PVC, and unlabeled "rubber" toys. For anything porous, use a condom barrier. Use only water-based lubricants with silicone. And when a toy smells strongly of chemicals right out of the box, trust that instinct.
