Choosing a non-toxic shower curtain

Did you see the title and roll your eyes? We know. We’ve been there. There’s only so much you can do to protect your family from the toxins of the world and just when you think you’ve got a lot of it covered, you learn about something else to avoid or change. Here’s the thing, when you know better you do better and a non-toxic shower curtain is an easy fix that you can control, unlike so many of the toxins in our environment that you can’t.

So let’s start with what makes many shower curtains, especially the liners, toxic. Many curtains and liners are made out of PVC. You may recognise this from the fresh smell that comes from the curtain when first unpacking it – it’s deceiving really, something that can smell like fresh water (at least that’s what it smells like to me at times) can really be so toxic. Really though, you can’t bottle fresh!

Not all PVC smells like this, however. No matter the smell (just trying to give you a point of reference), PVC, especially in the form of a shower curtain, is bad. Here’s why: “Vinyl chloride, the chemical used to make PVC, is a known human carcinogen, according to the World Health Organisation’s International Agency for Research on Cancer (IARC)”(Healthy Child Healthy World). It also causes reproductive damage, it irritates the nasal passages and the lungs, and it can cause headaches, among other things. One fact about vinyl chloride I find extra scary is this: An excess of spontaneous abortions has been reported among spouses of workers who had been exposed to vinyl chloride (Hazardous Substance fact Sheet). We realise this wasn’t from exposure in the shower, but the fact is that if it can do this much damage secondhand, it’s not safe to have around in an area where it’s used daily, especially in a shower, because the chemicals used to make PVC are released under warm and moist conditions, thus making a shower a dangerous place for these already hazardous compounds. What makes them leach is that the additives to PVC do not form a chemical bond with the plastic but exist within the PVC as a mixture. As a result plasticisers and other additives can migrate from the PVC polymer into the environment (Greenpeace).

PVC ALSO PRODUCES:

Dioxins – Dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer (World Health Organization).

Phthalates – “In the past few years, researchers have linked phthalates to asthma, attention-deficit hyperactivity disorder, breast cancer, obesity and type II diabetes, low IQ, neurodevelopment issues, behavioural issues, autism spectrum disorders, altered reproductive development and male fertility issues”(The Guardian).

Ethylene Dichloride – “Exposure to low levels of ethylene dichloride can occur from breathing ambient or workplace air. Inhalation of concentrated ethylene dichloride vapour can induce effects on the human nervous system, liver, and kidneys, as well as respiratory distress, cardiac arrhythmia, nausea, and vomiting. Chronic (long-term) inhalation exposure to ethylene dichloride produced effects on the liver and kidneys in animals. No information is available on the reproductive or developmental effects of ethylene dichloride in humans”(US Environmental Protection Agency).

Lead – The effects of lead normally accumulate over time through a series of low level doses. Children under the age of 6 and foetuses exposed through lead in their mother’s blood are most susceptible. Lead poisoning has been linked to anemia, central nervous system, kidney and immune system damage and learning disabilities. The degree of damage is dependent on the amount of lead taken into the body over time (UofM Department of Environmental Safety).

Organotins, Cadmium and Organochlorines are also found in PVC products.

NON-TOXIC OPTIONS TO PVC SHOWER CURTAINS

Many people are under the false assumption that EVA or PEVA liners are safe. While they are better than PVC, as they are made from chloride-free vinyl, they are still made from petroleum and contain chemicals, like plasticisers, that are used to make it pliable.

Hemp shower curtains have been around for a while. These are nice and thick, making for a great curtain, but have a tight enough weave that no liner is needed. Organic hemp fabric is naturally resistant to mildew, fungi and bacteria, so these will last a long time and is worth the investment.
