Nitrocellulose
What is Nitrocellulose?
Nitrocellulose is a synthetic polymer derived from cellulose, a natural polysaccharide from plant cell walls, through a nitration process that attaches nitro groups to enhance solubility in organic solvents. In cosmetics, it primarily appears in nail lacquers and hair styling formulations. Upon application and solvent evaporation, it dries to form a flexible, transparent film that adheres to surfaces, imparting high gloss, improving product longevity, and resisting water or wear. This film-forming action traps pigments and particles, preventing clumping or settling for uniform color and texture. Its non-comedogenic nature makes it suitable for various formulations without pore-clogging concerns, and it contributes to smooth application in both leave-on and rinse-off products.
