Polyvinyl alcohol (PVA) is generally considered safe for use in various applications and has low toxicity. When consumed orally, PVA is not absorbed by the body and passes through the digestive system without being metabolized. It is essentially inert and does not have any nutritional value.
Since PVA is water-soluble, excessive ingestion of large amounts could potentially cause gastrointestinal discomfort, such as bloating or diarrhea. However, it is worth noting that PVA is not intended for consumption and is not a food ingredient.
In medical and pharmaceutical applications, Polyvinyl alcohol is used in various forms, including eye drops, contact lenses, and drug delivery systems. In these cases, PVA is designed to be safe for specific uses and is tested and regulated accordingly.
As with any substance, it is important to use PVA in accordance with its intended purpose and follow safety guidelines provided by manufacturers. If you have specific concerns or questions about the use of PVA or any other substance, it is recommended to consult with a healthcare professional.
