It is an alcohol. But the only alcohol that is in beverages is ethyl alcohol.

The polyvinyl alcohol is soluble in water. Is Polyvinyl alcohol halal? PolyVinyl Alcohol is a synthetic polymer and it is Halal.

Polyvinyl alcohol is a synthetic resin prepared by the polymerisation of vinyl acetate, followed by partial hydrolysis of the ester in the presence of an alkaline catalyst. The physical characteristics of the product depend on the degree of polymerisation and the degree of hydrolysis. EU Food Improvement Agents.

Polyvinyl alcohol is used as an aid in suspension polymerizations. Its largest application in China is its use as a protective colloid to make polyvinyl acetate dispersions. In Japan its major use is the production of Vinylon fiber.

Polyvinyl alcohol is a man-made or synthetic polymer. PVA polymer molecule contains vinyl and alcohol groups. It is a very useful polymer due to its adhesive properties. PVA is water soluble, crystalline and flammable in nature. Presence of alcohol group in it makes it flammable.

Polyvinyl Alcohol is a synthetic water-soluble polymer which happens to be white (colourless) and odourless. It is also known as PVOH, PVA, or PVAl. The ideal formula of the Polyvinyl Alcohol or PVOH is [CH2CH(OH)]n and is widely used in the industry of papermaking, textiles and a variety of coatings.

PVOH, PVA, or PVAL - otherwise known as Polyvinyl alcohol - is a plastic (bendy and stretchy) that dissolves in water. It's become a popular material with many eco-friendly brands, but just how 'eco-friendly' is it really? Proponents say it 'biodegrades', but how long until takes to biodegrade is unclear.

By PVA – either polyvinyl acetate or polyvinyl alcohol, but the answer for either is no. Because the polymers are made via free radical polymerization through a vinyl group they are actually quite similar to polypropylene in terms of their polymer backbone. Polyvinyl alcohol or acetate just have some different side groups than polypropylene.
