Polyvinyl Alcohol
What is Polyvinyl Alcohol?
Polyvinyl Alcohol is a water-soluble synthetic polymer derived from the hydrolysis of polyvinyl acetate, a vinyl monomer polymerized under controlled conditions. Commonly found in rinse-off facial masks, cleansers, shampoos, and styling products, it functions by dissolving in water-based formulations to create flexible, cohesive films upon drying. As a binder, it unites powders and solids into durable compacts or sticks, enhancing structural integrity. Its film-forming ability deposits a sheer layer on skin or hair, promoting adhesion, water repellency, and removal of residues in peel-off applications. Additionally, it modulates viscosity, ensuring smooth flow, even suspension of particles, and pleasant sensory feel across lotions, gels, and emulsions. This multifunctional ingredient supports product performance without penetrating deeply into skin.
