Technically speaking, it means the material meets the requirements to use as a medical implant and is non-toxic when in contact with the body for prolonged periods of time. It’s the same material used to make breast implants and catheters, so we’re talking internal use too.
Medical-grade silicone is non-reactive, meaning it doesn’t breakdown, react with or degrade after being in contact with the body or bodily fluids.
Because medical-grade silicone is also non-porous and water-repellent, it is more resistant to bacterial and fungal growth than other more absorbent period products. That means it’s not a breeding ground for germs - and is why you can leave your Coralcone in for longer than you would tampons.
We chose our silicone because it is high quality and medical grade, meeting global standards such as ISO 10993, European Pharmacopoeia 3.1.9 and FDA 21 CFR 177.2600. There are varying grades of silicone, and not all of them are created equal. One way to test the quality of your cup is to stretch it. If it turns white, then there may be fillers or additives. High quality silicone should also be odourless. That’s why you’ll find no chemically, plasticky smells with our Coralcone cups.
The medical-grade silicone we use has a high tear strength and is durable enough to be medically sterilised without degrading, so you know you can get your cup perfectly clean.
Boiling your Coralcone to sterilise it or leaving it in direct sunlight won’t cause the silicone to breakdown, meaning you don’t ever have to compromise on hygiene.
We use only food grade colourants (mmmm delish!) that contain no heavy metals [2]. They are safe to combine with medical-grade silicone, and don’t affect the strength, hygiene or durability of the materials [3].
Just like the medical-grade silicone, the colours also don’t degrade or deteriorate at high heats or under UV light, meaning less discolouration over time.
The materials used for Coralcone are thoroughly researched and rigorously tested. We think it’s only right that we share the technical details with you, so you know exactly what’s going in your vagina.
