We’ve been getting a lot of questions about our podz. Are they wrapped in plastic? What's the casing made of? Does it contain microplastics? Here we go...
What is Polyvinyl Alcohol?
It’s a chemistry wonder! Polyvinyl Alcohol (PVA, PVOH or PVAI) is a synthetic polymer. This means it’s made up of many molecules strung together like a necklace. PVA starts as ethylene. Then, oxygen and acetic acid (or vinegar when it’s diluted) turn the ethylene into vinyl acetate — which is then dissolved into alcohol to become Polyvinyl Alcohol.
What is Polyvinyl Alcohol used for?
So many things you may not even realize!
- It makes yarn stronger.
- It makes fast food paper wraps grease resistant.
- It’s safe enough to be used in your eyes as a lubricant.
- It’s even used to create Slime!
Here at HopePodz, we use it to create the pods’ pouch that holds our glass, bathroom, multi-surface and disinfectant cleaning formulas.
Just drop the HopePodz refill (PVA-pouch and all) into an empty spray bottle, fill with water — and you’re ready to clean.
Is Polyvinyl Alcohol bad for you?
Does Polyvinyl Alcohol contain microplastics?
We get this question all the time! There is definitely a lot of misinformation out there. An independent German study (Degruyter, March 2021) concludes that the PVA in our Podz does NOT contribute to the Planet's micro-plastics issue.
According to the study:
- Our Podz PVA casing dissolves into a non-harmful monomer (i.e., NOT microplastics)
- The study concludes that PVA does NOT meet any of the definitions of micro-plastic: 1) it is not micro- or nano-sized; 2) it is highly water-soluble; 3) it is biodegradable in the environmental condition where it is discharged (i.e., the bottle you saved from landfill)
In addition, HopePodz are Green Seal Certified to 100% biodegrade into a non-harmful monomer that's safe for aquatic life & eventually decompose into reusable nutrients over time.
To sum up: the science tells us PVA non-toxic monomers are a whole lot better than having billions of single-use plastic bottles in landfill, or even worse, in our poor ocean animals’ stomachs.
Is Polyvinyl Alcohol the same as Polyvinyl Acetate?
Nope! It’s easy to confuse the different polyvinyl polymers, especially since they all go by PVA. Polyvinyl acetate (aka PVA, PVAc) is used in wood glue. Polyvinyl chloride is a poisonous plastic. Our HopePodz' Polyvinyl Alcohol is the non-toxic, biodegradable polymer.
That's why we always say that HopePodz (especially the PVA casing) are a chemistry wonder!
