Pvp

PVP (polyvinylpyrrolidone) is a film-forming binder/fixative used in cosmetics (e.g., hair sprays, mascaras, skincare) typically around ~0.1–5%, and it is generally well tolerated because it is a large, non-reactive polymer with minimal skin penetration. Clinical experience and patch-test data suggest low irritancy overall, though occasional stinging/irritant reactions can occur from film formation/occlusion or impurities and in highly compromised barriers (e.g., eczema), so I do not classify it as fully inert. Safety Notes: In consumer skincare and personal care, PVP (polyvinylpyrrolidone) is most often used as a film former/binder or styling-fixative polymer, with very low levels (~0.05–0.5%) appearing in leave-on lotions/serums and some cleansers to aid feel, adhesion, or film formation. Mid-range usage (~1–5%) is common in peel-off masks and certain long-wear or water-resistant leave-on formats where a stronger polymer film is desired. The highest OTC levels observed are in high-hold film-forming products (e.g., peel-off masks and adjacent consumer cosmetics/personal care fixatives) where PVP can reach ~10–15% depending on grade/viscosity targets; it is not specifically concentration-restricted by FDA/EU, with practical limits driven by tack, flaking, and solubility/viscosity.
