Dewaxed Bleached Shellac is a highly refined, light-colored natural resin derived from seedlac through an aqueous-alkali process followed by controlled bleaching using Sodium Hypochlorite. This method ensures the removal of natural waxes and the lightening of the resin to its near-transparent form, making it especially suitable for applications that demand high purity and minimal coloration. Once bleached, the shellac is precipitated with Sulphuric Acid and then dried, yielding a product that retains the versatile and film-forming properties of shellac while meeting stringent aesthetic and safety standards. Being non-toxic, food-safe, and biodegradable, Dewaxed Bleached Shellac is a favored ingredient in cosmetics, food coatings, pharmaceutical coatings, and specialty industrial formulations.
