Body-Safe Materials for Sex Toys: The Complete Guide

The safest materials for a sex toy are medical-grade silicone, borosilicate glass and stainless steel: they are non-porous and clean thoroughly. Soft PVC and jelly can contain phthalates, and TPE is porous and doesn't last long. Plasticising phthalates (DEHP, DBP, BBP) have been banned in children's toys for 20 years, and since July 2020 the EU has capped four phthalates (DEHP, DBP, BBP and DIBP) at 0.1% in the flexible plastic of items that touch mucous membranes or skin for prolonged periods, sex toys included. Even so, a cheap product with no technical data sheet may be made from materials that don't meet those limits.

This guide explains the 8 materials found on the market, with their real porosity, the tests and standards that matter (USP Class VI, ISO 10993, REACH), home tests to spot toxic materials before you use them, and how to clean each material properly.

TL;DR

If you've got 30 seconds

  • ✓ Buy: 100% medical silicone, borosilicate glass, 316L surgical steel, good-quality ABS plastic. The first three are non-porous and can be sterilised; ABS is non-porous but must not be boiled.
  • ⚠ Be careful with: TPE/TPR (porous, 1-2 year lifespan), latex (some people are allergic), real leather (can't be sterilised).
  • ✗ Avoid: jelly/gelatin/soft PVC: they may contain phthalates (endocrine disruptors and toxic to reproduction) and other additives. A strong chemical smell is a red flag.
  • → Smell test: open the packaging. If it smells strongly of "new car plastic", do NOT use it internally. Medical silicone is practically odourless.
  • → Uncomfortable truth: in the EU there is no specific regulation for sex toys as medical devices. They don't go through prior approval like a medicine, but general product safety and chemical substance rules do apply to them, and complying with those rules is the responsibility of the manufacturer and the seller. Even so, it's best to buy from shops that publish the material of each product.

2. The science: porosity, phthalates and why it matters

Body-safe isn't a marketing term, it's a technical concept with verifiable criteria. A body-safe material meets 3 conditions at once: (1) non-porous at microscopic level, (2) chemically inert (doesn't transfer compounds to the body), (3) able to withstand sterilisation methods. If it fails even one, it isn't body-safe.

What is porosity and why is it critical?

Porosity measures how much a material absorbs liquids, bacteria and residue at a microscopic level. The rectum and vagina contain dense bacterial flora : fungi, bacteria, viruses. A porous material traps that flora in its surface, where it multiplies between uses however well you wash the visible surface.

With a porous material, cleaning reaches the inside less well, which is why it's recommended to use it with a condom and replace it over time. Non-porous materials (silicone, glass, steel) clean much better, but washing them doesn't make them sterile. In a small study of 12 women (Anderson et al., 2014), right after cleaning the vibrators with a commercial cleaner, HPV was still detected in 44% of the samples from the silicone one and 56% from the TPE one; after 24 hours it was only still present on the TPE one. If you share your toy, use a condom.

Phthalates: the invisible contaminant

Phthalates are plasticisers that make PVC and TPE flexible. They are known endocrine disruptors : they alter hormonal systems with prolonged exposure. The EU banned DEHP, BBP and DBP in children's toys in 2007 and, since July 2020, has capped those three and DIBP at 0.1% in the flexible plastic of any item that touches mucous membranes or skin for prolonged periods, such as a sex toy. There is no specific standard for sex toys and no check before sale. That's why it's worth checking what each product is made of before you buy it.

Independent analyses have detected phthalates in "novelty" toys sold on major platforms.

Why is medical silicone the standard?

Medical-grade silicone is silicone that has passed biocompatibility tests such as USP Class VI or ISO 10993. These are lab tests, not a legal seal: USP Class VI covers short-term contact with tissue, not long-term implants, and the manufacturer can claim it without anyone checking. It is biocompatible, non-porous, hypoallergenic, resistant to temperatures of 200°C+ (which is why it withstands boiling), and doesn't degrade with normal use. That's why it's the gold standard: it meets all 3 body-safe conditions at once, with room to spare.

3. The 8 materials explained

①

100% medical silicone: the gold standard

It has passed biocompatibility tests such as USP Class VI. Hypoallergenic, non-porous, boilable. Reputable brands (LELO, Fun Factory, Tantus, We-Vibe, Womanizer) use 100% medical silicone.

Be careful: "silicone" with no further qualifier can be industrial silicone mixed with other polymers. Look for "100% medical grade silicone" in the specs.

How to identify it: slightly matte surface, not sticky, no smell. Boil it in water: if it releases a chemical, it is NOT pure medical silicone.

②

Borosilicate glass: practically indestructible

The same material as laboratory glassware. It handles temperature changes well, but avoid extreme jumps (from freezer to boiling water): it can chip or break. It's chemically inert and lasts many years if it isn't knocked.

Pros: can be sterilised indefinitely, conducts temperature (temperature play), a uniquely smooth feel, transparent to show depth.

⚠ Fragile if dropped. Inspect before each use for micro-cracks (colour/light changes). Brands: Nebula by Ibiza, Icicles.

③

316L surgical steel: the most durable

Surgical-grade stainless steel (the same as orthopaedic implants and needles). Inert, hypoallergenic, non-magnetic, resistant to corrosion from body fluids.

Be careful: NOT 304 steel (industrial) or galvanised steel. Confusing labels are common, so look specifically for "316L surgical steel". Brands: njoy, Le Wand, Metal Hard.

The only drawback: weight (250-700g typical). Ideal for temperature play or intense sensations.

④

Good-quality ABS plastic: for casings

Rigid, non-porous plastic that contains no phthalates. It's the material of the external parts of many toys (Womanizer, Satisfyer casings, etc.).

Pros: affordable, lightweight, easy to clean.

Cons: it can NOT be boiled (warps at 80°C+), and internal use only if it's covered in silicone or is high-quality sealed ABS.

ABS alone doesn't guarantee that a toy is safe: in a pilot in vitro study with extracts from 20 toys (Svobodova et al., 2020), several ABS, PVC and latex samples gave positive results with possible effects on health, repeatedly. It's a small sample, but it's a reason for the part that goes inside to be silicone, glass or steel and not just ABS.

⑤

Natural latex: allergens and degradation

An elastic natural material. Body-safe in itself, but 1-3% of adults are allergic to latex (more among people with previous hospital exposure).

Be careful: oils (massage oil, petroleum jelly, creams) degrade it and can break a condom. Water-based or silicone-based lubricant is safe with latex. Short lifespan (1-3 years from natural oxidation).

Its use has declined: silicone is better in almost every way. Latex is still common in condoms but less so in toys.

⑥

TPE / TPR: the acceptable problem material

Thermoplastic elastomer. Softer and more "skin-like" than silicone, and much cheaper. It's porous : it traps bacteria on the surface.

Acceptable for: solo use (no partner), masturbators with a short life cycle (1-2 years), low-cost pocket toys.

NOT acceptable for: deep internal use, sharing with a partner, use without a condom.

If you buy TPE, replace it every 12-18 months. Daily cleaning and drying it completely are essential.

⑦

Soft PVC: the problem material

Flexible plastic, VERY cheap to make. It usually contains phthalates (10-30% of its weight) to make it elastic. A strong, characteristic chemical smell : you can tell as soon as you open the packaging.

Risk: phthalates are endocrine disruptors (they alter hormones). Prolonged exposure on mucous membranes hasn't been studied in humans for ethical reasons, but animal studies show effects.

Recommendation: avoid for internal use. Acceptable only for external toys without sustained contact (e.g. cock rings).

⑧

Jelly / Gelatin: AVOID

The worst material on the market. It usually combines PVC + phthalates at 25%+ + industrial plasticisers. Extreme chemical smell, sticky, rubbery texture.

Why it's still sold: it's super cheap. It's still sold as a "novelty" in some low-cost shops.

If you read "jelly", "jelly-like" or "jelly-soft" in the specs: do NOT buy it for internal use. Replacing it with equivalent silicone costs more up front, and it's worth the investment.

4. Head to head: 4 common dilemmas

⚔️ Medical silicone vs TPE: cost vs health

The classic budget dilemma: pay more for medical silicone, or less for TPE?

Medical silicone: higher upfront cost but lower annualised cost (10+ years of life). Sterilisable. No risks.

TPE: 1/3 of the price, but you have to replace it every 1-2 years. Cleaning limitations. Cost over 5 years: one silicone toy versus three to five TPE replacements. Similar in economic terms; for health, silicone wins hands down.

⚔️ Silicone vs glass: flexibility vs feel

Both are top-tier body-safe. The choice is down to preference, not safety.

Silicone: flexible, warm to the touch, soft. Better for beginners and for longer use.

Glass: rigid, with a uniquely smooth texture, conducts temperature (hot/cold). A more intense feel because of its hardness. Best for temperature play and for experienced users who want controlled firmness.

⚔️ 316L steel vs ABS: durability vs price

For rigid external toys or accessories.

316L steel: indefinite lifespan, a weight of 250-700g adds to the sensation. Absolute premium.

ABS: 5-10 year lifespan with normal use, lightweight, comfortable to handle. Better choice for beginners and when weight matters (small hands).

⚔️ Real leather vs synthetic leather (BDSM)

For whips, paddles, handcuffs and accessories.

Real leather: lasts decades with care. But it can NOT be sterilised (body fluids ruin it). Only for use without contact with fluids.

Synthetic leather (PU): can be cleaned with a cloth and soap. Cheaper. Better for intensive use or if fluids are involved. Lifespan 2-5 years.

6. Home tests: is it really body-safe?

If you have a toy and aren't sure what it's made of, there are four home checks that give you clues. None of them is proof: only a lab analysis confirms what a toy is made of.

Test 1: The smell test (most reliable)

Open the new packaging. Bring your nose to the toy (not TOO close).

  • ✓ Odourless or a slight neutral smell: probably medical silicone, glass or steel.
  • ⚠ A mild "new plastic" smell: ABS or mid-quality TPE.
  • ✗ A STRONG "new plastic" smell, chemical, like petrol: high probability of PVC/jelly with phthalates. Do NOT use.

Test 2: The boiling water test

Only for toys with no motor or battery, made of a material that tolerates 100 °C: silicone, glass or steel. Never for a vibrator or for TPE, ABS or jelly.

  • Submerge the toy in boiling water for 60 seconds.
  • ✓ Water stays clear, no smell: pure material.
  • ✗ Water turns cloudy, releases dye or smells chemical: it contains releasable additives/phthalates.

Test 3: The fire test (we don't recommend it)

We don't recommend this test: burning plastic releases irritating fumes, it destroys the toy and it isn't a reliable test. If you've seen it on other sites, treat it only as a clue and ask the seller for the material data sheet instead.

  • ✓ Pure silicone: it chars, leaving white/grey ash. It does NOT smell strongly of burning. It does NOT drip.
  • ✗ TPE/PVC: it melts into a sticky blob, gives off toxic black smoke and has a strong chemical smell.

Test 4: The stretch test

Gently stretch a flexible part of the toy.

  • ✓ Medical-grade silicone: it springs back to shape instantly and isn't left deformed.
  • ⚠ TPE: it returns to shape after a slight delay (1-2 sec).
  • ✗ Jelly/PVC: it stays partly deformed and recovers slowly.

7. How to clean each material

MaterialDaily cleaningDeep sterilisingCompatible lubricants
Medical-grade siliconeWarm water + mild soap or a toy cleanerBoil for 5 min OR dishwasher (no battery)Water-based lubricant ONLY (silicone lube damages the material)
Borosilicate glassWarm water + soapBoil for 5 min · dishwasher · isopropyl alcoholAny type (water, silicone, oil)
316L steelWarm water + soapBoil for 5 min · isopropyl alcohol · autoclaveAny type
ABS plasticWarm water + mild soapDo NOT boil · toy cleanerWater- or silicone-based
LatexWater + mild soapDo NOT boil · NO alcoholWater or silicone; never oils
TPE / TPRWarm water + antibacterial soapNOT sterilisable: replace every 12-18 monthsWater-based lubricant ONLY

Universal rules

  • Clean straight after use. Bacteria multiply exponentially in warm residue. Don't wait until the next morning.
  • Dry completely. Moisture trapped in cavities = mould/bacteria. Use a microfibre cloth, then leave to air-dry for 30 min.
  • Store each toy in its own fabric bag. Plastics can react with other materials (silicone in particular can stick to other silicone).
  • NEVER use silicone lubricant on a silicone toy. It causes chemical degradation: invisible micro-cracks that ruin the toy and can harbour bacteria.

8. Frequently asked questions (14 honest answers)

Why aren't sex toys regulated like children's toys?

Because of how they're classified in law. Sex toys are consumer products: they aren't medical devices or children's toys and have no standard of their own, but the general rules do apply to them. Since July 2020, for example, REACH has limited four phthalates (DEHP, DBP, BBP and DIBP) to 0.1% in flexible plastic that touches mucous membranes or skin for a prolonged time. The problem is compliance: a cheap product with no data sheet gives you no guarantees. Brands such as LELO, Womanizer or Fun Factory state in their product details what material their products are made of.

How do I know if a toy is really medical-grade silicone or just "branded" silicone?

3 indicators: (1) the data sheet says "100% medical grade silicone" or "USP Class VI". If it only says "silicone": it's probably a blend. (2) It survives boiling without warping or giving off a smell. (3) A brand with a good reputation: LELO, Fun Factory, Tantus, We-Vibe, Womanizer (heads). If you're unsure, ask for the material data sheet: no home test is conclusive.

Is it safe to buy toys on big marketplaces (Amazon, AliExpress)?

Medium-high risk. These platforms don't verify what materials are used. Independent studies have found discrepancies between what's declared in the specs ("100% silicone") and lab analysis (blends with PVC). Our advice: if you buy on a general marketplace, stick to well-known brands with a track record you can check. If you want to experiment with cheap toys, buy from a specialist sex shop, where the retailer is responsible.

Has my old jelly toy harmed me?

Realistically, the acute risk from a one-off use of a jelly toy is low: the effects of phthalates come from cumulative exposure. If you've used it now and then, there's no reason to panic. If you've been using one regularly for years, it's a good idea to switch to medical-grade silicone from now on. There's no need to have tests done or anything like that.

How much does it cost to get into body-safe toys?

Much less than you think. A Satisfyer Pro 2 (silicone and ABS), a silicone dildo of around 12 cm such as the Fun Factory Limba Flex S or a Satisfyer bullet vibrator: safe doesn't mean expensive. The barrier isn't money, it's information.

Do I need to sterilise my toys, or is cleaning enough?

For normal personal use, basic cleaning with soap is enough. Sterilising is only necessary if: (1) you share with a partner, (2) you switch areas (anal → vaginal), (3) after a bacterial or vaginal infection. Sterilising monthly as a routine is good practice if you use your toys a lot.

Can glass or steel cause physical harm?

If they're well made, NO. Borosilicate glass is the same as laboratory glassware: it won't break under normal pressure. 316L steel can't be deformed. The real risk: dropping it on the floor (glass can crack, so CHECK it before every use). With steel: weight (250g+) can cause uncomfortable pressure if you're not used to it.

Why do some toys smell of "perfume" or "bubblegum"?

Scenting: chemical compounds (not natural ones) are added to mask the smell of PVC/jelly. It's a red flag: if the material needs perfuming, it's because it smells of chemicals. Medical-grade silicone is naturally odourless. Sweet bubblegum smells are typical of toxic jelly.

Can you rely on "phthalate-free" certifications?

It depends. "Phthalate-free" is a manufacturer's claim, and in most cases not an independent certification. Reputable brands (LELO, Tantus) have third-party tests done and publish the results. Low-cost brands simply claim it with no verification. Look for "tested by SGS" or similar in the specs: that is an independent certification.

Can wood be body-safe?

Yes, but only wood SEALED with resin or medical-grade lacquer (not industrial lacquer). Brands such as NobEssence work hardwood with a sealant made for internal use. Lifespan 3-5 years (the lacquer wears away). NOT sterilisable. Appealing look, but it needs specific care.

Can I trust "medical grade" labelling without checking?

Not automatically. "Medical grade" with no further detail is marketing in many cases. Look specifically for "USP Class VI" (US Pharmacopeia tests) or "ISO 10993" (the international biocompatibility standard). These are real lab tests, although they're usually declared by the manufacturer itself.

What about toys with a motor (vibrators)? How does the material affect them?

The outer body is usually ABS (the casing) and the part that touches your body is medical-grade silicone. That combination is body-safe. Be careful with cheap vibrators where EVERYTHING is jelly or TPE: the motor generates heat, which speeds up the release of plasticisers. Premium brands (LELO, Womanizer) are always safe in this respect.

Can I use a toy that has changed colour/texture over time?

No. A change in colour/texture points to chemical degradation: the material is releasing compounds. Especially with TPE/PVC: if the surface has gone sticky or yellowed, throw it away. With pure silicone, this should NEVER happen. If it does, it probably wasn't pure silicone.

Are there European quality marks for sex toys?

Not specific to the category. But there are applicable standards: "CE" (basic European compliance, NOT body-safe), "ISO 10993" (biocompatibility of medical products), "USP Class VI" (US standard for medical plastics). Serious brands voluntarily seek at least one of the last two. If only "CE" appears: it only meets basic electrical safety rules (relevant for vibrators) but does NOT certify the material.

9. Verdict + our selection

Our verdict

4 materials are body-safe without question: medical-grade silicone, borosilicate glass, 316L stainless steel and, for casings and parts that aren't inserted, good-quality ABS. Before you buy, check the material in the product details. We also sell toys made of TPE and TPR, which are porous: if you choose one, use a condom, clean it thoroughly and replace it when it degrades. If you have doubts about a specific toy, ask us in the chat: we have the specs for all of them.

If you only remember one tip: check the material in the product details before you buy. Any toy that smells strongly of chemicals when you open the packaging: do NOT use internally.
