Polyvinylpyrrolidone ethanol
Did you know?
PVP is soluble in water and other polar solvents. For example, it is soluble in various alcohols, such as methanol and ethanol, as well as in more exotic solvents like the deep eutectic solvent formed by choline chloride and urea (Relin). When dry it is a light flaky hygroscopic powder, readily absorbing up to 40% of its weight in atmospheric water. In solution, it has excellent wetting properties and readily forms films. This makes it good as a coating or an additive to coatings.
