For liquid detergent packaging, a suitable grade of PVA (Polyvinyl Alcohol) is often one with a high degree of hydrolysis, typically around 80-88%, combined with a medium to high molecular weight. This ensures good solubility in water and provides the necessary strength and durability to withstand handling and storage conditions. Additionally, grades with low viscosity are preferred for ease of processing and filling.
In quantities equal in a fifth yes you can get drunk from polyvinyl alcohol
Polyvinyl alcohol (PVA) is made by the hydrolysis of polyvinyl acetate, which involves breaking down the acetate groups in polyvinyl acetate to form the alcohol groups in PVA. This process typically involves the use of a catalyst and water to facilitate the reaction. The degree of hydrolysis determines the properties of the resulting PVA polymer.
Heat is needed to assist in dissolving polyvinyl alcohol because it increases the kinetic energy of the solvent molecules, allowing them to break the intermolecular forces holding the polymer chains together. This results in a faster and more thorough dissolution of the polyvinyl alcohol in the solvent.
Mixing borax and polyvinyl alcohol does not result in a chemical change. Instead, it forms a physical change known as cross-linking, where the borax molecules create bonds with the polyvinyl alcohol molecules to form a flexible slime-like material.
PVOH is one abbreviation (though probably not the most common) for poly(vinyl alcohol).
PolyVinyl Alcohol is a synthetic polymer and it is Halal.

Is polyvinyl alcohol detected by scram bracelet
Polyvinyl alcohol was first prepared by Hermann and Haehnel in 1924 by hydrolyzing polyvinyl acetate in ethanol with potassium hydroxide.
No, polyvinyl alcohol is not flammable. It is a synthetic polymer that does not easily catch fire or burn.
Polyvinyl alcohol is used to make hospital laundry bags because it has good tensile strength, water solubility, and biodegradability. These properties make it suitable for holding soiled laundry in hospital settings where infection control and cleanliness are a priority. Additionally, polyvinyl alcohol can easily dissolve in water, making it convenient for washing the laundry without having to remove it from the bag.
Polyvinyl alcohol is made through the hydrolysis of polyvinyl acetate. The key steps in its production process include polymerization of vinyl acetate, hydrolysis of the polymer to form polyvinyl alcohol, purification, and drying.
It is an alcohol. But the only alcohol that is in beverages is ethyl alcohol.

Polyvinyl alcohol is a covalent compound because it is made up of carbon, hydrogen, and oxygen atoms that are linked together through covalent bonds. It does not contain any ions.
