Ingredient Transparency
You asked about PVA. Good. You should. We are not going to dodge it.
PVA is polyvinyl alcohol. It is the thin film that holds the sheet together. It dissolves the second it touches water.
It is the same material in dishwasher pods. Laundry pods. Medical products. Food packaging.
It is a synthetic polymer. People call it plastic. That is where the fear starts.
But a plastic bottle is built to last for decades. PVA is built to dissolve and break down. Those are not the same thing.
Dissolving is not the same as breaking down. This is the honest concern. It is the right one.
Sugar dissolves. Then it biodegrades. Some things dissolve. Then they linger.
So the real question is simple. Once our PVA is gone from sight. Does it actually break down.
We tested it to find out.
Our PVA was tested to OECD 301B. It is the international standard for ready biodegradability. It measures how much of a material microbes turn into CO2 over 28 days. The pass mark is 60%.
It passed the mark inside the first week. It reached 90% by day 28.
Here is the part that matters most. This test uses ordinary microbes. Not special ones trained on PVA. Our sheet still broke down to 90%. That is not a material vanishing from view. That is a material being eaten and gone.
We keep the full report private because it names our manufacturing partner. If you have a real technical reason to see it. Email us and we will talk.
The fear is that dissolved PVA turns into microplastic in the water. The biodegradation result is the direct answer to that.
It does not stay as intact polymer. Microbes consume it. A material that passes a ready-biodegradability test is the opposite of one that persists.
We are not going to tell you PVA has zero footprint. Nothing does. We will tell you ours is tested. It clears the standard. It behaves like a dissolving sheet should.
The film dissolves fully. It rinses away in the wash. Nothing coats your fabric.
The molecules are far too large to pass through skin. They cannot enter your body.
And here is a fair thing to sit with. A refillable spray bottle is still plastic. It sheds. It stays under your sink for years. A sheet that dissolves leaves you nothing to keep.
Because the thing it replaces is worse. The plastic jug is heavy. Rigid. Single use. It ships water around the world. It sits in landfill for decades.
A film that dissolves and passes a biodegradation test beats another plastic jug. Every time. That is the comparison that actually matters. It is the one the jug brands would rather you never made.
We are not done. We are researching alternatives to PVA right now. As Aira grows we will move into real testing of replacement materials.
We are not there yet. We will not pretend we are. We would rather not depend on a synthetic polymer at all. That is the direction we are heading. It is not a box we have already ticked.
If we find something better and prove it works. You will read it here first.
