Polyvinyl Pyrrolidone (PVP)

[Product Introduction]

Homopolymer of Vinylpyrrolidone is a versatile ingredient widely used in the Cosmetics & Personal Care industry. It forms clear aqueous solutions at all concentration levels, and the polymers are non-ionic, meaning neutralization is not required. It excels at stabilizing suspensions, emulsions, and dispersions, making it an ideal Thickening Agent in a variety of cosmetic formulations. The polymer demonstrates high compatibility with inorganic salts, resins, and other Cosmetic Raw Materials, which makes it suitable for use in diverse cosmetic products. Additionally, films formed by this polymer have a high capacity for water absorption, offering moisturizing and conditioning properties.
