"Body-safe" is printed on almost everything and means almost nothing on its own. There's no certification behind it, no regulator checking, and no legal definition — a seller can write it about a material they'd rather not name.
Which is why the useful skill isn't recognising the phrase. It's reading a listing and working out what you're actually being sold.
The short answer
A material is body-safe if it's non-porous, phthalate-free, and named. Medical-grade silicone, borosilicate glass and stainless steel meet all three. TPE is porous but acceptable if you treat it as a consumable and replace it. Anything sold as "jelly", "skin-like", "premium material" or with no material stated at all should be avoided — because those aren't materials, they're the absence of an answer.
The single test that does most of the work
Does the listing name the material?
That's it. A seller confident in what they're selling states it plainly, because it's a selling point. A seller using vague language is usually not withholding by accident.
| This is a material | This is not |
|---|---|
| Medical-grade silicone | Premium material |
| Body-safe TPE / TPR | Skin-like / lifelike |
| Borosilicate glass | Jelly |
| Stainless steel | Soft touch |
| ABS plastic | Medical grade (of what?) |
Porosity — the property that actually matters
Everything else is downstream of this one.
Non-porous means the surface has no microscopic openings. Nothing gets in, so washing genuinely cleans it and it can be sterilised. Porous means the surface has openings you can't see, where fluid and bacteria can sit. Washing removes what's on the surface; it can't reach what's below.
That single difference determines whether a toy can be shared, whether it can be boiled, and how long it lasts.
| Material | Porous? | Sterilise? | Lasts | Verdict |
|---|---|---|---|---|
| Medical silicone | No | Yes — boil 3–5 min if no motor | Years | The default. Buy this unless there's a reason not to. |
| Borosilicate glass | No | Yes | Indefinite unless chipped | Excellent. Rigid, so not a first purchase. Inspect for chips. |
| Stainless steel | No | Yes | Effectively forever | Excellent. The weight is the point. Not a starter. |
| ABS plastic | No | Wipe only | Years | Fine. Usually handles and bases rather than contact surfaces. |
| TPE / TPR | Yes | No — heat damages it | Months to ~2 years | Acceptable if treated as a consumable. Softer and cheaper — that's the trade. |
| "Jelly" / unnamed | Usually, unknown | No | Unknown | Avoid. May contain phthalate softeners. You have no way to check. |
The bit where we tell you something that costs us
We sell both silicone and TPE. Adam™ and Peach Please™ Medium are TPE, and TPE is porous, cannot be boiled, and will need replacing eventually.
That's the honest trade: TPE is softer, stretchier and cheaper than silicone, which is genuinely better for some things — a stroker sleeve needs to stretch in a way silicone doesn't. The cost is that it's a consumable rather than a lifetime object.
You should know that before you buy rather than discovering it in eight months. If a seller isn't willing to tell you which of their products are porous, ask why.
Phthalates, briefly
Phthalates are chemical softeners historically used to make hard plastics flexible and squishy. They're what made old "jelly" toys feel the way they did, and they're the reason those toys often had a strong chemical smell.
Reputable manufacturers stopped using them in body-contact products years ago, and any decent listing states "phthalate-free" explicitly. The risk today sits almost entirely with cheap unbranded products where nothing is stated.
The practical signal: a strong chemical or plasticky smell out of the packet is a bad sign. Body-safe silicone smells of essentially nothing.
Four checks before you buy
- Is the material named? If not, stop here.
- Does it say phthalate-free? Reputable sellers say so plainly.
- Are there real dimensions? Length and, for anything insertable, width. A seller who publishes specs is a seller who knows their product.
- Is there a warranty? Ours is 180 days. Nobody warranties something they expect to fail.
And two after it arrives: smell it (chemical is bad), and feel it (tacky or greasy straight out of the box is a bad sign — quality silicone feels dry and slightly matte).
What we make, and out of what
| Product | Material | What that means for you |
|---|---|---|
| Noah™ · Beads™ · Arc™ | 100% medical-grade silicone, phthalate-free | Non-porous. Soap and water is genuinely enough. Lasts years. Don't boil — they have motors. |
| Adam™ | 100% body-safe TPE | Porous. Never boil. Dry completely inside and out. Replace when it turns tacky. |
| Peach Please™ Medium | Body-safe TPE | Porous. Use a condom if sharing. Water-based lube only. A consumable. |
Prices correct at the time of writing. Material named on every product page, 180-day warranty across the range.
Ways to get this wrong
- Trusting the words "body-safe" alone. No certification sits behind them.
- Buying from a listing that won't name the material. The single clearest red flag there is.
- Assuming soft means safe. Softness usually means softeners.
- Ignoring a chemical smell. Good silicone smells of nothing.
- Sharing a porous toy without a barrier. Cleaning can't reach below the surface.
- Boiling TPE. Heat damages it. Silicone only, and only without a motor.
- Silicone lube on silicone. Permanent surface damage on first contact.
- Keeping a TPE toy forever. It's a consumable. Replace it when it turns tacky.

Frequently asked questions
What does body-safe actually mean?
Non-porous, phthalate-free, and named. There's no certification or legal definition behind the phrase itself, so it means nothing on its own — what matters is whether the seller states the actual material. Medical-grade silicone, borosilicate glass and stainless steel all qualify.
Is silicone or TPE better?
Silicone is non-porous, can be sterilised and lasts years. TPE is porous, can't be boiled and lasts months to a couple of years. TPE is softer, stretchier and cheaper, which suits some products genuinely well — the trade is that it's a consumable.
What is porosity and why does it matter?
A porous surface has microscopic openings where fluid and bacteria can sit below the surface, where washing can't reach. It determines whether a toy can be shared safely, whether it can be sterilised, and how long it lasts. It's the property everything else follows from.
Are jelly sex toys safe?
Avoid them. "Jelly" isn't a material, it's a texture description covering unknown plastics that historically contained phthalate softeners. Since you can't tell what's in it, and it's porous, there's no way to use it confidently.
What are phthalates?
Chemical softeners historically used to make hard plastics squishy — they're what made old jelly toys feel the way they did, and why those toys often smelled strongly of chemicals. Reputable makers stopped using them in body-contact products years ago.
How can I tell if a toy is body-safe after it arrives?
Smell it and feel it. Body-safe silicone smells of essentially nothing and feels dry and slightly matte. A strong chemical or plasticky smell, or a tacky greasy surface straight out of the packet, are both bad signs.
Can I sterilise my sex toy?
Silicone, glass and steel can be boiled for three to five minutes if there's no motor inside. TPE cannot — heat damages it. Anything with electronics gets soap and warm water only, never submersion.
Is medical-grade silicone different from ordinary silicone?
It's a higher purity standard with tighter controls on what's in it, which is why reputable sellers specify it rather than just saying "silicone". In practice, look for the phrase alongside "phthalate-free" — sellers who meet the standard say so.
Why is my toy sticky?
The material is breaking down, which happens with porous materials like TPE over time. If washing doesn't fix it, it's time to replace it. A cornstarch-based renewing powder can restore softness temporarily, but never use talc.
Does more expensive mean safer?
Not reliably. Price mostly tracks brand, import costs and marketing. What tracks safety is whether the material is named, whether phthalate-free is stated, and whether the seller publishes real specs and offers a warranty — all of which a modestly priced product can do.
We make sex toys, not diagnoses — this is a guide, not professional advice. For adults, obviously.
