Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone.

Uses
Used in the cosmetics and beauty industry as a binder film former, emulsion stabilizer, suspending agent and hair fixative, and is seen primarily in products such as mascara, eyeliner, hair conditioners, hair sprays, shampoos and other hair care products, according to the Cosmetics Database and CosmeticsInfo.org.
Benefits
- It keeps emulsions from separating into their oil and liquid components, and hold together the ingredients of a compressed tablets or cakes. Polyvinylpyrrolidone (PVP) also has the ability to dry and form a thin coating on the skin, nail or hair, and when it is seen as an ingredient in hair products, it is used to hold hair styles in place by preventing the hair’s ability to absorb moisture. It is also used in contact lens solution, and as the thickening agent in whitening toothpastes and tooth whitening gels (Wikipedia).Polyvinylpyrrolidone (PVP) is FDA approved (specifically “as a clarifying agent in beer, wine, and vinegar, and as an adjuvant in coatings on fresh citrus fruits”) and CIR approved as well.
Cautions
- The U.S. Food and Drug Administration (FDA) has approved this chemical for many uses, and it is generally considered safe. However, there have been documented cases of allergic reactions to PVP/povidone, particularly regarding subcutaneous (applied under the skin) use and situations where the PVP has come in contact with autologous serum (internal blood fluids) and mucous membranes. For example, a boy having an anaphylactic response after application of PVP-Iodine for treatment of impetigo was found to be allergic to the PVP component of the solution. A woman, who had previously experienced urticaria (hives) from various hair products, later found to contain PVP, had an anaphylactic response after povidone-iodine solution was applied internally. She was found to be allergic to PVP. In another case, a man experiencing anaphylaxis after taking acetaminophen tablets orally was found to be allergic to PVP.Povidone is commonly used in conjunction with other chemicals. Some of these, such as iodine, are blamed for allergic responses, although testing results in some patients show no signs of allergy to the suspect chemical. Allergies attributed to these other chemicals may possibly be caused by the PVP instead.
