Medical-grade silicone menstrual cups – the benefits

Menstrual cup materials: why silicone?

A menstrual cup completely replaces disposable period products like pads and tampons. It's sustainable, because it can be reused again and again for many years. Menstrual cups are made from silicone, thermoplastic elastomer or rubber. Medical-grade silicone products are manufactured under strict quality controls to meet the applicable FDA and EU regulations. Read on to find out why we only recommend a menstrual cup made from medical-grade silicone.
Why silicone?
Silicone is one of the most versatile materials there is. It found its way into our homes long ago, and we're not exaggerating when we say: silicone is now almost everywhere. Liquid silicone often appears in the form of pastes and gels in personal care products. The kitchen would be hard to imagine without it, too: as silicone rubber it's used for baking tins and mats, ice cube trays and dummies, for example.
Unlike plastic, silicone is not made from crude oil, which makes it safer for your health. No fossil fuels are needed for its production either.
Chemically speaking, silicones are long chains of silicon and oxygen atoms (= silicon oxide). Did you know that these elements bond with each other particularly readily? Two thirds of the earth's crust consists of exactly this compound. Sand and pebbles are nothing other than just that. We'll skip the rest – this isn't a chemistry lesson, after all: through further processing, "sand" becomes the all-rounder "silicone".
Unlike many types of plastic, silicone needs no plasticisers, is tear-resistant, UV-resistant and far more durable. But what's an advantage on one side is a drawback on the other: because it lasts so long, silicone is also difficult to biodegrade, so it's important that it is recycled properly.
What is medical-grade silicone?
From condoms to lipstick to creams, as a gel, oil or resin, for catheters or contact lenses, as a sealant or for insulation – silicone is everywhere. But wait! Not all silicone is created equal. A distinction is made between industrial silicone, food-grade silicone and medical-grade silicone.
In short: medical-grade silicone has properties that allow safe, close contact with living tissue. It is considered non-toxic and hypoallergenic, meaning it only very rarely triggers allergies. That's why it's used so widely in the medical field, for example for prostheses, probes, implants such as pacemakers, artificial joints and contact lenses.
Medical-grade silicone has to meet higher standards than industrial silicone. Medical-grade silicone products are manufactured under strict quality controls to comply with the applicable FDA and EU regulations.
The benefits of medical-grade silicone
100% medical-grade silicone: menstrual cups by SELENACARE
Our SELENACARE period cups are all made from 100 per cent medical-grade silicone. Menstrual cups are generally very well tolerated, as they don't dry out the vaginal flora. They collect the fluid rather than absorbing it. Dry vaginal flora is more susceptible to infections and vaginal thrush.
Tip: If your vagina happens to be very dry, simply moisten the menstrual cup with warm water or a water-based lubricant to make insertion even easier. When the menstrual cup is full – which, depending on how heavy your flow is, can take around 4–12 hours – it's simply emptied, cleaned and reinserted.
Menstrual cup vs. tampon
A medical-grade silicone menstrual cup beats a tampon by miles: it's gentler, as it doesn't dry out the vagina, it can hold more blood, and it's cheaper, because it can be reused for many years. For comparison:
A regular tampon can absorb an average of 9–12 millilitres of fluid, while a super tampon reaches its limit at 18–21 millilitres. Our menstrual cups, on the other hand, can hold between 21 and 33 millilitres of blood, depending on the size.
A period cup is also very leak-proof and adapts to your every movement, making it ideal for sport too. You can even go swimming with it without any trouble.
Say goodbye to disposables
The waste created every day around the world by tampons and pads is enormous and, above all, one thing: unnecessary. On top of that, many people simply flush their pads or tampons down the toilet, which causes even more problems.
With the knowledge and options we have today, using disposable hygiene products like pads and tampons simply no longer feels in keeping with the times. Their use is hard to reconcile with a clear conscience.
While a menstrual cup isn't made from renewable raw materials either, its lifespan of several years is considerably longer, saving a huge amount of single-use waste. If we assume that we menstruate 500 times in our lives and use several tampons and/or pads over three to five days each time, every menstruating person gets through 10,000 to 17,000 period products in their lifetime. More than 600,000 happy customers can't be wrong.
