Biodegradability of Polyvinyl Alcohol Based Film Used for Liquid Detergent Capsules

Abstract Questions and potential misperceptions have arisen about the contribution of liquid detergent capsules to environmental microplastics issue. The film these detergents is highly water soluble, also in cold water, as it must fully dissolve during every type washing process. Water-soluble grades polyvinyl alcohol, most commonly used capsule material, are recognised be biodegradable. In current paper, adequate biodegradability confirmed by means ready biodegradation screening tests, across a range alcohol grade films. high solubility itself implies that films not within microplastic scope. Furthermore, their ensures there no concern for persistence or accumulation environment.
