We have all asked ourselves, should we worry about plastic particles in our water bottles? Read on to find out!
BPA, BPS, BPF and other acronyms in your Water
First things first: Yes, plastic residues in water can and do have a harmful effect on health.
Sounds logical and most people are aware of this. Ever since this information first hit the media, it has been impossible to imagine our supermarkets without the "BPA free" slogan.
BPA or "bisphenol A" is a plasticizer used in many plastic products. Plasticizers like BPA have been shown to have estrogen-like effects in the body, throwing the respective sex hormones of both genders out of balance. One result associated with increased exposure to BPA has been declining sperm counts in men for years. A study published in 2017 speaks of a 52.4 percent decrease between 1973 and 2011. (HumanReproductiveUpdate: Levine et al., 2017) An unnatural increase in estrogens is also not good for the female body. A number of different cancers, like breast cancer, are associated with hormone imbalance.
The result of this commercially disseminated knowledge is a decrease in the use of BPA. Other plasticizers and substitutes, such as BPS (bisphenol S), BPF (bisphenol F) or DEHP (diethylhexyl phthalate) are finding increased use as a result. As the name of the first two already suggests, BPS and BPF come from the same family as BPA and presumably have largely similar effects on the human organism. Basically more of the same.
Okay, it should be noted that plasticizers have no place in the body. But let us assume a utopian world where a plastic bottle does not contain any plasticizers. What else is there?
Study after study found that so-called microplastics have become an integral part of our environment. We breathe plastic, eat plastic, and unfortunately, we drink plastic. While certain foods, such as seafood, can be deliberately avoided to reduce plastic pollution, there is one elixir of life that cannot be dispensed with.
The daily consumption of water is an integral part of a healthy diet and is also essential for survival. An average fluid intake of 2l ensures the maintenance of vital bodily functions.
So where does the water we drink come from?
Unfortunately, not all of us have our own spring behind the house, so the choice often ends up being bottled water. And not too seldom the water comes, for various reasons, in plastic bottles. These are much lighter than glass bottles and, unfortunately, often the cheapest version of mineral water in the supermarket.
Aside from the fact that most "inexpensive" water bottles are quite obviously full of plasticizers, there is another, much more general, problem with using them.
The plastic from which the bottles themselves are made.
According to this survey from the State University of New York:
- 259 individual bottles from 27 different batches of 11 brands were tested. They were purchased at 19 locations in 9 countries.
- 93% of the bottled water showed signs of microplastic contamination.
- With microplastic residues about 100 microns in size, roughly the diameter of a human hair, bottled water samples contained more than twice as many microplastic pieces per liter (10.4) as tap water samples (4.45).
Okay, got it. Avoid plastic bottles. If you have to, buy in glass bottles in a supermarket. We have a direction now, but… the study leads us to believe that a harmful part of the plastic residues in the water are due to the lid. 54% of the polymers detected was polypropylene, a commonly used plastic for bottle lids. This is usually also made of plastic in glass bottles and the process of first unscrewing ("crack!") causes small plastic particles to enter the water.
Well... tap water it is. In many European countries, tap water is of drinking water quality anyway and is often checked more critically than some bottled water. But what do we fill the water from the tap into? Ideally, into a bottle that is easy to carry and without danger of simply breaking when we put it down. Sounds like a plastic bottle again, or am I mistaken?
As mentioned above, this is not the solution. A better bottle must be found! Which is what we set out to do.
At KEEGO, we have made it our mission to counteract the problem of the "pay-off" between the practicality of a plastic bottle and the health benefits of using a metal bottle and, somehow, to merge these two worlds. But how do you get a bottle that is light and squeezable like a typical plastic bottle and tasteless and plasticizer-free like a metal bottle? We decided on a core made of titanium and an outer layer made of qualitative soft-touch material, which protects the sensitive core and gives the bottle a pleasant touch.
Welcome to the world of KEEGO.
