Polyvinylpyrrolidone is a water-soluble polymer commonly used in the pharmaceutical, cosmetic and food industries, not a plastic in the traditional sense.
PVP is highly regarded for its ability to help substances dissolve in water and is often used to increase the solubility of drugs and vitamins. It can also act as a binder, thickener and emulsifier, making it a valuable ingredient in cosmetics and personal care products.
While PVP has important industrial uses, it is generally considered safe for humans and the environment. It is non-toxic and biodegradable and does not accumulate in the environment like many other plastics.
