The PVA/PVOH film used in Ariel PODS® is safe, water-soluble, and is not considered a microplastic under either the European Chemicals Agency (ECHA) definition or the EU Synthetic Polymeric Microparticles Regulation. The safety of water-soluble grades of PVA/PVOH that are used in POD® films has been thoroughly assessed by regulatory bodies around the world, including ECHA, European Food Safety Authority (EFSA), the US Environmental Protection Agency (EPA), the US Food and Drug Administration (FDA), and the US-based Center for Research on Ingredient Safety (CRIS). This article explains the science behind this material and its proven safety.
What is PVA/PVOH?
PVA/ PVOH is a versatile polymer derived from common ingredients: ethylene gas and acetic acid. Ethylene gas is a naturally occurring compound that ripens fruits like bananas, while acetic acid is the key component of household vinegar. The material properties of PVA/PVOH are well known and approved for use in a range of everyday items including food, medicine, and cosmetics and textiles for over 20 years.
Why is PVA/PVOH used in Ariel PODS®?
In Ariel laundry detergents, specialized, water-soluble grades of PVA/PVOH form the film that encapsulates the liquid detergent. This innovative technology allows for a pre-measured dose of detergent, ensuring convenience and preventing spills. The film is engineered to be strong and stable when dry, protecting the detergent until use, but to rapidly dissolve upon contact with water during the wash cycle.
Is the PVA/PVOH used in Ariel PODS® plastic? Does it contribute to microplastic pollution?
The films used in Ariel products are water-soluble and completely dissolve upon contact with water during use. They meet all regulatory safety criteria mandated by the Classification, Labelling and Packaging (CLP) Regulation and do not contribute to microplastic pollution, as per both the ECHA definition and that of the EU Synthetic Polymeric Microparticles Regulation.
Does the PVOH / PVA film used in Ariel PODS® biodegrade in the environment?
Studies have been done on the water-soluble grades of PVOH/PVA as used in Ariel PODS® films using the OECD 301 test series, which are generally considered to be conservative; these studies demonstrate the film components degrade, and do not persist or build up in the environment.

Is the PVOH / PVA film used in Ariel PODS® safe?
Yes, all ingredients used in Ariel PODS®, including the water-soluble grade PVOH/PVA used in the detergent film are safe for consumers and non-harmful to the environment when used and disposed of as intended. PVA/PVOH has been rigorously tested for safety and is approved for food, medicine, and cosmetics and textiles for over 20 years.
Which other ingredients are present in the film besides PVA/PVOH?
Other common ingredients in the film include naturally sourced materials like glycerol (for flexibility) and surfactants (to improve solubility and processing), like those found in soaps and shampoos.
