Sodium Chlorate
What is Sodium Chlorate?
Sodium chlorate is an inorganic compound, the sodium salt of chloric acid (NaClO3), manufactured industrially via electrolysis of brine. In cosmetics, it functions mainly as an oxidizing agent in oxidative hair colorants and bleaches, enabling dye precursors to form permanent colors through precise electron transfer reactions. It also serves in deodorants by oxidizing volatile sulfur compounds from bacteria, thus curbing odor without halting perspiration. This strong yet controlled oxidizer requires formulation expertise to maintain product stability, prevent unwanted reactions, and ensure compatibility with other actives like hydrogen peroxide in hair systems. Its presence supports reliable performance in targeted personal care items, distinguishing it from milder antioxidants.
