Activated charcoal powder is a fine, black powder made from carbon-rich materials like wood, coconut shells, or coal. It's processed at high temperatures with steam or gas to make it highly porous. This porous structure increases its surface area, allowing it to "adsorb" (bind to) toxins and impurities from liquids and gases. Key characteristics Porous: The activation process creates numerous tiny pores within the charcoal particles, greatly expanding its surface area. Adsorbent: It effectively attracts and binds toxins and other substances to its surface, preventing their absorption into the body or removal from water/air. Negatively Charged: The porous texture also creates a negative electrical charge, which attracts positively charged molecules like toxins and gases. Fine Texture: Usually in powdered form, it can also be found as granules, pellets, or even infused in cloth.
