Colgate Zig Zag, one of India’s leading toothbrush brands, is now equipped with 100% Anti-Bacterial bristles, transforming into Colgate Zig Zag Anti-Bacterial. Infused with Silver Ions, these unique bristles inhibit bacteria build up on the bristle surface. Silver Ions (Ag+) attach themselves to the cell membrane on the surface of the Anti Bacterial product. Incoming Cell's protein wrapped bacteria will be destroyed on contact with the metal ion. Destroyed bacteria become extinct when it comes in contact with air keeping the surface bacteria-free.
