The Claim No One Checks
No regulator inspects those three words. No standards body certifies them against a sex-toy benchmark, because no such benchmark exists in India. A seller can print “medical-grade silicone” on a product moulded from something far cheaper and far less stable, and face nothing for having done so.
The distance between the claim and the proof is the entire subject of this article. Material is the one decision in intimate wellness that your body cannot forgive later. A motor can disappoint you. A shape can be wrong. Those are matters of preference, and you move on. The surface pressed against the most permeable tissue you own is a matter of health, and it does not negotiate. It is why every object LaNoira curates starts with one question long before it reaches shape or function: what is it actually made of, and can that be proven.
At a Glance
- “Medical-grade silicone” is not a certified standard in India. It is a claim, and the burden of proof sits with the seller, not a regulator.
- The property that matters is non-porosity. A non-porous surface can be cleaned completely. A porous one cannot, which is why it is the real risk.
- Platinum-cured silicone is the standard you pay a little more for. It is inert, stable, odourless, and can be boiled for sterilisation.
- The materials to avoid are jelly rubber, PVC, and most TPE or TPR, along with anything sold as a vague “silicone blend” or “silicone feel”.
- Independent research has found that common toy materials shed microplastics and carry phthalates, a class of hormone-disrupting compounds.
- In an unregulated market, you verify material three ways: a stretch-and-pinch check, the smell, and, above all, a seller willing to state the exact grade in writing.
What “Medical-Grade Silicone” Actually Means, and What It Doesn’t
The term sounds precise. It is not. There is no single global definition of “medical grade,” and there is certainly no Indian one written for intimate products. The phrase describes a silicone that has been tested against a recognised biocompatibility standard, formulated for sustained contact with the body. The honest version of the sentence ends there, with testing, not with a government seal.
Two standards do the real work behind the label. The first is USP Class VI, an American pharmacopoeia benchmark for materials in shorter-term bodily contact. The second is the ISO 10993 series, a broader biological evaluation used for devices that sit in or on the body for longer periods.
ISO 10993 defines biocompatibility as the ability of a material to perform with an appropriate response from the body in a specific application. That is the language a credible manufacturer can point to. It is also language you will almost never see on a cheap listing, because the material underneath was never put through it.
A common misunderstanding needs clearing here. People assume the FDA, or some equivalent, “approves” medical-grade silicone. It does not approve raw materials in isolation. Regulators approve finished devices built from materials that meet a given standard. So a manufacturer cannot truthfully say their silicone is “FDA approved” as a substance.
What they can say, if it is true, is that the material meets USP Class VI or has been evaluated under ISO 10993. The precision of the claim tells you a great deal about the people making it.
Then there is the question of cure, which is where quality quietly separates itself. Silicone is set, or cured, in one of two ways. Peroxide curing is cheaper and leaves behind by-products that can make the material less stable and more prone to leaching over time. Platinum curing, named for the platinum catalyst that drives the reaction, produces a cleaner, more inert result.
Platinum-cured silicone is the grade to seek out by name. It gives off no strange odour, holds its integrity under heat, and tolerates boiling without degrading. When a product is described specifically as platinum-cured or as liquid silicone, the maker is signalling that they understand the distinction and have paid for the better side of it. You can feel the difference in something like our liquid-silicone dildos, where the material is the point rather than an afterthought.
Why Non-Porosity Is the Whole Argument
Strip away the vocabulary and one physical property decides whether a material belongs against your body. Porosity. It is less glamorous than motor technology and less visible than finish, and it matters more than either.
A porous material is riddled with microscopic openings, far too small to see, large enough to hold what you cannot remove. Bodily fluids, lubricant, and residue settle into those spaces during use. Bacteria, yeast, and mould follow. No amount of washing reaches fully inside a porous surface, which means a porous toy cannot be sterilised. It can only be made to look clean. Every subsequent use builds on what the last one left behind.
A non-porous material has no such hiding places. Its surface is sealed, so nothing penetrates below it, and a proper clean genuinely removes what needs removing. This is the single reason platinum-cured silicone, borosilicate glass, and surgical steel sit at the top of every credible list. They can be taken back to a truly hygienic state, again and again, across years of use.
India sharpens this point in a way global guides tend to miss. Our climate is not neutral. Through the monsoon and across the humid months, warmth and moisture accelerate microbial growth, and a porous toy stored in a bathroom cupboard becomes a small, damp reservoir of everything it has absorbed. A sealed silicone surface endures that environment.
A porous one degrades in it. We treat storage as part of material care for exactly this reason, and we set out the full method in our guide to cleaning and storing intimate wellness products.
The Materials Dressed Up to Look Safe
The counterfeit of safety is more dangerous than its honest absence, because it disarms you. Several materials dominate the cheaper end of the Indian market, and most of them are porous, unstable, or both. Knowing their names is the beginning of refusing them.
Jelly rubber and PVC are the oldest offenders. Soft, translucent, often strongly scented, they are porous and frequently contain plasticising additives to achieve that squishy feel. That chemical smell rising from a new toy is not a manufacturing quirk to air out. It is the material itself, off-gassing.
TPE and TPR, thermoplastic elastomer and its rubber variant, are the modern replacements and the more confusing case. They feel pleasant, they cost little, and they are genuinely popular. They are also porous at the microscopic level, which means they carry the same fundamental limitation: they cannot be fully sterilised. Some TPE formulations contain phthalates. Others do not.
Without laboratory testing, you cannot know which is in your hands, and the label will not tell you honestly. The cautious position, and ours, is to treat TPE as unsuitable for internal use, to use a barrier if you own one already, and to replace it on a short cycle rather than trusting it indefinitely.
Then there is the cleverest deception of all, the one aimed squarely at buyers who have learned that silicone is the answer. A product described as a “silicone blend,” “silicone feel,” or “premium silicone material” is almost never solid medical-grade silicone. The vague phrasing is deliberate.
It allows a maker to include a small fraction of real silicone alongside cheaper, porous fillers, and still invoke the word that sells. Specificity is your defence. “One hundred per cent platinum-cured silicone” means something. “Silicone feel” means someone is choosing their words to avoid a commitment.
The health concern beneath all of this is no longer speculative. A 2023 study from researchers at Duke University and Appalachian State, published in the journal Microplastics and Nanoplastics, tested four categories of commercially available toys and found that each shed micro and nanoplastic fragments under abrasion, and that all of them contained phthalates.
Phthalates are a class of compounds associated with hormone disruption, which is why they are restricted in children’s products across much of the world. The researchers were careful to say their abrasion method represents accelerated wear rather than ordinary use, and that further investigation is warranted.
The signal, even stated conservatively, is reason enough to care what sits against your body. Non-porous, properly cured silicone is how you remove yourself from that experiment.
The Body-Safe Shortlist
Enough of what to avoid. The materials that earn a place are few, and they are best known by their qualities rather than their marketing.
Platinum-cured silicone is the most versatile of them and, for most people, the right default. It is non-porous, soft enough to feel considered against the skin, hypoallergenic, and chemically inert. It carries vibration beautifully, which matters for anything motorised, and it tolerates thorough cleaning.
One caution travels with it, and we return to it below: it must be paired with the correct lubricant. This is the material behind most of our silicone intimate instruments, and it is where a nervous first buyer can place their trust without reservation.
Borosilicate glass surprises people. It is non-porous, entirely free of leaching concerns, and strong enough to resist thermal shock, which is why it can be warmed or cooled for temperature play. It cleans perfectly and lasts, in practice, indefinitely.
Surgical stainless steel, specifically the 316L grade, is the other non-porous metal that earns a mention. Weighty, elegant, easy to sterilise completely. The grade matters here, because cheaper steels can contain enough nickel to trouble sensitive skin. 316L is the specification to look for.
ABS hard plastic completes the shortlist, usually as the rigid casing of a vibrator rather than the insertable surface. It is non-porous and safe, with a single limitation to remember: it cannot be boiled, because it will deform under that heat. For ABS, warm water and a body-safe cleanser is the method.
How to Verify Material in a Market That Won’t Do It for You
Since no Indian authority will check the claim for you, the responsibility becomes yours, and it is more manageable than it sounds. A handful of checks will separate the credible from the counterfeit most of the time.
Start before anything physical, with the seller’s language. A trustworthy source states the exact grade in writing and does so specifically. Platinum-cured. One hundred per cent silicone. A named standard such as USP Class VI. Evasion is itself an answer. If a listing will only say “silicone feel,” or if a question about the precise material is met with vagueness, you have learned what you needed to learn.
The quality of a store’s disclosure is the quality of its products, and it is a central reason to buy from a source whose standards you can actually interrogate, a point we make in our guide to buying intimate wellness in India.
With the object in hand, a few physical tells help. The stretch-and-pinch check is the simplest: genuine solid silicone stretches and springs back cleanly, while a filled or blended material can feel oily, tacky, or oddly sticky at the surface. Smell is the next instrument. Real platinum-cured silicone is essentially odourless.
A chemical or plasticky scent is the material announcing itself, and it is a reason to stop. For the committed, a flame test is definitive but destructive: pure silicone resists catching, tends to leave a white or grey ash, and self-extinguishes, where TPE and rubber will readily ignite and keep burning. It will ruin the toy, so it is a test for a suspect object you have already decided not to trust, not for something you intend to use.
None of these is a laboratory. True certainty comes only from independent testing, which is neither practical nor affordable for an individual buyer. That is precisely why the material question should be settled by the seller’s integrity before a product ever reaches you. The verification you do at home is a safeguard. The verification that counts was supposed to happen before the sale.
Living With the Material You Chose
Owning the right material is the start. Keeping it in good condition asks for two small disciplines, both easy once they are habit.
The first is lubricant, and it carries the one genuine pitfall of silicone. A silicone-based lubricant can bond with and slowly degrade a silicone toy, clouding and spoiling that flawless surface over time. The pairing to use is water-based, which is kind to both silicone and skin. We set out the full logic of this choice in our comparison of water-based and silicone-based lubricants, and it is the reasoning behind keeping a good water-based lubricant alongside anything made of silicone.
The second is cleaning, which non-porous materials make genuinely simple. Warm water and a pH-balanced, body-safe cleanser before the first use and after every use is the whole of it. Fully silicone, glass, and steel pieces with no motor can be boiled for a deeper sterilisation. Anything with a motor, battery, or charging port never goes near boiling water, and is cleaned by hand instead. The material rewards the care by lasting, cleanly, for years.
The LaNoira Standard
We do not stock jelly rubber. We do not stock PVC, and we do not stock TPE for internal use. This is not an aesthetic preference, and it is not a way to justify a price. It is the one line we drew before the brand existed, because material is the place where a compromise costs the buyer rather than the seller.
Every object in our collection is chosen for non-porosity and provenance you can question. Platinum-cured and liquid silicone, borosilicate glass, surgical steel, properly specified ABS. When we call a material medical-grade, we mean a grade we can name and stand behind, not a phrase borrowed to close a sale. A first purchase should be the beginning of trusting this category, not a gamble you only understand in hindsight, which is the spirit of our beginner’s guide to luxury wellness instruments.
The market will keep printing three reassuring words on products that have not earned them. You now know what the words are supposed to mean, why the proof matters more than the claim, and how to tell the difference in your own hands. That knowledge is the real protection. Everything else follows from it.
Frequently Asked Questions.
No. India has no regulatory body and no standard that certifies sex toy materials, which means the phrase is a seller’s claim rather than a verified seal. The way to judge it is to ask whether the seller will name the exact grade in writing. A credible source states something specific, such as platinum-cured, one hundred per cent silicone, or a recognised benchmark like USP Class VI. Vagueness is itself the answer.
It is the method used to set the silicone. Peroxide curing is cheaper and leaves behind by-products that can make the material less stable and more prone to leaching over time. Platinum curing, named for the platinum catalyst that drives the reaction, produces a cleaner, more inert result that gives off no odour and tolerates boiling without degrading. When a product is described as platinum-cured or as liquid silicone, the maker understands the distinction and has paid for the better side of it.
TPE is porous at the microscopic level, which means it holds fluids and residue in spaces that cleaning cannot fully reach. A porous toy cannot be sterilised, only made to look clean. Some TPE formulations also contain phthalates, and without laboratory testing you cannot know which does. Our position is to treat TPE as unsuitable for internal use. If you already own one, use a barrier such as a condom every time and replace it on a short cycle.
Two simple checks help. The stretch-and-pinch test: genuine solid silicone stretches and springs back cleanly, while a filled or blended material feels oily, tacky, or sticky at the surface. The smell test: real platinum-cured silicone is essentially odourless, so a chemical or plasticky scent is the material announcing itself. A flame test is definitive but destructive, since pure silicone resists catching and leaves a pale ash where TPE and rubber ignite and keep burning. None of these is a laboratory, which is why the grade should be settled by the seller before a product reaches you.
No. A silicone-based lubricant can bond with and slowly degrade a silicone surface, clouding and spoiling it over time. The correct pairing is water-based, which is kind to silicone, glass, steel, and skin alike. This is the one genuine pitfall of an otherwise forgiving material, and it is easily avoided once you know it.
A 2023 study from Duke University and Appalachian State, published in the journal Microplastics and Nanoplastics, tested four categories of commercially available toys. Each shed micro and nanoplastic fragments under abrasion, and all of them contained phthalates, a class of compounds associated with hormone disruption. The researchers noted that their method represents accelerated wear rather than ordinary use, and called for further investigation. The signal, even stated conservatively, is reason to care. Non-porous, properly cured silicone removes you from the concern entirely.
